Abstract PDF: The coronavirus disease 2019 (COVID-19) pandemic prompted the development of messenger RNA vaccines. Following extensive vaccination campaigns worldwide, several adverse reactions to these vaccines have been reported. This is a case series of unilateral lower extremity lymphedema after COVID-19 vaccination in two patients with a history of cervical cancer. An 82-year-old woman and a 68-year-old woman visited the outpatient clinic with unilateral leg edema after receiving a COVID-19 booster vaccine (BNT162b2; Pfizer-BioNTech) in the deltoid muscle. Both patients had a common history of cervical cancer treated with surgery, chemotherapy, and radiotherapy and were in complete remission. Gynecological evaluations, including laboratory and imaging studies, revealed no specific findings. Lymphoscintigraphy revealed delayed lymphatic drainage with diffuse dermal backflow in a unilateral lower extremity. This case series explores adverse reactions to COVID-19 vaccination in patients who are at high risk of developing lymphedema, providing novel data for similar clinical presentations.

Abstract PDF: BACKGROUND
We investigated the difference in right ventricle (RV) volume and ejection fraction (EF) according to the pulmonary valve (PV) annular extension technique during Tetralogy of Fallot (TOF) total correction. METHODS: We divided patients who underwent the procedure from 1993 to 2003 into two groups according to PV extension technique (group I: PV annular extension, group II: no PV annular extension) during TOF total correction. We then analyzed the three segmental (RV inlet, trabecular and outlet) and whole RV volume and EF by cardiac magnetic resonance imaging (MRI). RESULTS: Fourteen patients were included in this study (group I: 10 patients, group II: four patients; male: nine patients, female: five patients). Cardiac MRI was conducted after a 16.1 years TOF total correction follow-up period. There was no statistical difference in RV segmental volume index or EF between groups (all p>0.05). Moreover, the total RV volume index and EF did not differ significantly between groups (all p>0.05). CONCLUSION: The RV volume and EF of the PV annular extension group did not differ from that of the PV annular extension group. Thus, PV annular preservation technique did not show the surgical advantage compared to PV annular extension technique in this study.

Abstract PDF

We report on a patient who showed visual recovery following bilateral occipital lobe infarct, as evaluated by follow up functional magnetic resonance imaging (fMRI) and diffusion tensor tractography (DTT). A 56-year-old female patient exhibited severe visual impairment since onset of the cerebral infarct in the bilateral occipital lobes. The patient complained that she could not see anything, although the central part of the visual field remained dimly at 1 week after onset. However, her visual function has shown improvement with time. As a result, at 5 weeks after onset, she notified that her visual field and visual acuity had improved. fMRI and DTT were acquired at 1 week and 4 weeks after onset, using a 1.5-T Philips Gyroscan Intera. The fiber number of left optic radiation (OR) increased from 257 (1-week) to 353 (4-week), although the fiber numbers for right OR were similar. No activation in the occipital lobe was observed on 1-week fMRI. By contrast, activation of the visual cortex, including the bilateral primary visual cortex, was observed on 4-week fMRI. We demonstrated visual recovery in this patient in terms of the changes observed on DTT and fMRI. It appears that the recovery of the left OR was attributed more to resolution of local factors, such as peri-infarct edema, than brain plasticity.

Abstract PDF: PURPOSE: To radiologically differentiate renal oncocytoma from other renal solid tumors, we analyzed and characterized, retrogradely, radiologic findings of renal oncocytomas. MATERIALS AND METHODS: Radiologic findings of pathologically proven renal oncocytoma were analyzed in 9 patients. CT was performed in all patients, ultrasonography in 4 patients and MRI in 3 patients. (51) RESULTS: On ultrasonography, the echogenicity of the mass was slightly more hyperechoic than normal renal parenchyma in all 4 cases. Two cases were homogeneous and the remaining two cases were relatively homogeneous. On CT, all 8 cases showed iso-density to slightly low density compared to normal renal parenchyma and 5 cases were homogeneous but the central portion of the mass was of a slightly lower density than the peripheral portion in 3 cases. All six cases had an arterial phase scan and were heterogeneously enhanced. An irregular, lower-enhancing portion was found in the central portion of the mass. Segmental inversion of contrast enhancement was found in 5 of 6 cases that had a dynamic enhancement study. On MR T1-weighted imaging, the mass was of iso-signal intensity to normal renal parenchyma and the central portion of the mass had a slightly hypo-signal intensity than the peripheral portion. On T2-weighted imaging, 2 cases were heterogeneous; the peripheral portion was of low signal intensity and the central portion was of higher signal intensity than normal renal parenchyma. One case was relatively homogeneous and showed a slightly lower signal intensity than that of normal renal parenchyma, except for a central small portion showing high signal intensity. For 2 cases that had a dynamic study, a segmental inversion of contrast enhancement was noted. CONCLUSION: Renal oncocytoma is seen as a well-marginated solid mass lesion. On enhanced scans it is heterogeneously enhanced and segmental inversion of contrast enhancement may be seen. The possibility of oncocytoma can be suggested in cases showing these radiologic findings.

Abstract PDF: PURPOSE: The purpose of this study was a phantom study to measure the diffusion properties of water molecules by steady-state free precession diffusion-weighted imaging (SSFP-DWI) with a low b-value and to determine if this sequence might be useful for application to the evaluation of bone marrow pathology. MATERIALS AND METHODS: 1. The phantom study: A phantom study using two diffusion weighted sequences for the evaluation of the diffusion coefficient was performed. Three water-containing cylinders at different temperatures were designed: phantom A was 3degrees C, B was 23degrees C and C was 63degrees C. Both SSFP and echo planar imaging (EPI) sequences (b-value: 1000 s/mm2) were performed for comparison of the diffusion properties. The Signal to noise ratios (SNR) and apparent diffusion coefficient (ADC) values of the three phantoms using each diffusion-weighted sequence were assessed. 2. The Clinical study: SSFP-DWI was performed in 28 patients [sacral insufficiency fractures (10), osteoporotic lumbar compression fractures (10), malignant compression fractures (8)]. To measure the ADC maps, a diffusion-weighted single shot stimulated echo-acquisition mode sequence (650s/ mm2) was obtained using the same 1.5-T MR imager RESULTS: For the phantom study, the signal intensity on the SSFP as well as the classic EPI-based DWI was decreased as the temperature increased in phantom A to C. The ADC values of the phantoms on EPI-DWI were 0.13x10(-3) mm2/s in phantom A, 0.22x10(-3) mm2/s in B and 0.37x10(-3) mm2/s. in C. The SSFP can be regarded as a DWI sequence in view of the series of signal decreases. CONCLUSION: Bone marrow pathologies with different diffusion coefficients were evaluated by SSFP-DWI. All benign fractures were hypointense compared to the adjacent normal bone marrow where as the malignant fractures were hyperintense compared to the adjacent normal bone marrow.

Abstract PDF

Purpose：The aim of this study was to compare the dose distribution of intensity modulated radiation therapy (IMRT) with 3 dimensional conformal radiation therapy (3DCRT) in prostate cancer. Materials and Methods：The IMRT plan and the 3DCRT plan used the 9 fields technique, respectively. In IMRT, tumor dose was a total dose of 50 Gy at 2.0 Gy per day, 5 days a week for 5 weeks. All cases were following the dose volume histogram (DVH) constraints. The maximum and minimum tumor dose constraints were 5,075 cGy and 4,925 cGy, respectively. The rectum dose constraints were <35% over 40 Gy. The bladder dose constraints were <35% over 30 Gy. The femur head dose constraints were <15% over 16 Gy. Tumor dose in the 3DCRT were 50 Gy.
Results
：In IMRT, the maximum dose of PTV was 101.9% and minimum dose was 89.5% for given dose. In 3DCRT, the maximum dose of PTV was 103.5% and minimum dose was 86.5% for given dose. The rectum dose was 29.2% over 40 Gy in IMRT compared with 67.9% in 3DCRT. The bladder dose was 30.1% over 30 Gy in IMRT compared with 30.6% in 3DCRT. The right femur head dose was 5.3% over 16 Gy in IMRT compared with 8.3% in 3DCRT. The left femur head dose was 6.8% over 16 Gy in IMRT compared with 9.1% in 3 DCRT.
Conclusion
：The dose of critical organs (rectum, bladder, and femur head) in IMRT showed to reduce than dose of 3DCRT. The rectum dose over 40 Gy in IMRT was reduced 38.7% than 3DCRT. The bladder dose over 30 Gy in IMRT was similar to 3DCRT. The femur head dose over 16 Gy in IMRT was reduced about 2.3∼3% than 3DCRT.

Abstract PDF: Purpose：This study compared 3 dimensional conformal radiation therapy (3DCRT) to intensity modulated radiation therapy (IMRT) in parotid glands sparing in head and neck cancers. Materials and Methods：Planning target volume (PTV) was outlined on each CT slice. The dose of 50.4 Gy was prescribed to the PTV with the conventional fraction, 5 fractions per week. We also outlined spinal cord and both parotid glands. With Eclipse 3 dimensional planning system, 3DCRT and IMRT planning were done.
Results
：After plan optimization, PTV dose distribution was evaluated with dose volume histogram. The 90% isodose curve covered almost all of PTV for both techniques. Maximum and median dose for spinal cord were 36.8 Gy and 34.2 Gy in 3DCRT, 39.9 GY and 37.5 Gy in IMRT. For parotid glands, mean and median dose were 33.6 Gy and 37.6 Gy in 3DCRT, 24.9 Gy and 24.5 Gy in IMRT.
Conclusion
：For the non-pharyngeal head and neck cancers, 3DCRT was cost effective radiation modality in prevention radiation therapy induced xerostomia.

Abstract PDF: Adrenal glands are relatively small than other upper abdominal solid organs but they are affected by complex physiologic and neoplastic processes. In the past, normal adrenal gland and small adrenal masses are difficult to examine because adrenal gland is small and located deeply in the abdominal cavity. However, by the recent remarkable advance of the MR and CT machines and imaging techniques detection of normal adrenal gland and detection and differential diagnosis of various adrenal lesions are possible. And so radiology is playing a critical role in not only the detection of adrenal abnormalities but in characterizing them as benign or malignant. In the diagnosis of adrenal lesions, various imaging modalities are used including, ultrasonography, CT, MR imaging and nuclear medicine imaging. Ultrasonography plays a role as a screening imaging modality. CT is the imaging modality of choice for both detection and characterization of adrenal masses. MR imaging is a problem solving modality in cases of inconclusive or insufficient on CT. The purpose of this article is to give an overview of adrenal diseases and their imaging appearances and describe the current concepts of differentiating a benign from a malignant adrenal mass.

Abstract PDF: A thromboembolic stroke is believed to be precipitated by a rupture of vulnerable atheromatous plaques. Until recently the assessment of a further risk of stroke in high-risk patients in whom atherosclerosis has presented with a transient ischaemic attack (TIA), has been confined to a quantitative assessment of the luminal patency of the internal carotid artery. These traditional stratification parameters are no longer believed to be the most accurate predictors of a thrombo-embolism. This is because the process of vessel wall remodeling can maintain a luminal patency, and consequently, quite large friable plaques may remain unidentified. Accordingly, there is a need for an improved risk assessment. The fibrous cap of a vulnerable plaque is thinner, and an intraplaque hemorrhage and inflammation can occur during the development of atherosclerotic plaque. Several imaging methods for identifying vulnerable plaques have been developed. Recently, high resolution magnetic resonance (MR) imaging has emerged as an accurate non-invasive tool that can characterize the carotid plaque components in vivo. A High resolution carotid magnetic resonance is capable of distinguishing an intact, thick fibrous cap from a thin and ruptured cap in carotid plaque. In addition, a plaque MR can identify the active inflammation and detect a hemorrhage. High resolution carotid MR imaging is a valuable noninvasive method for quantifying the plaque components and identifying vulnerable plaque.

Abstract PDF

Even though the nonketotic hyperglycemia is a metabolic disorder, it complicates hemic- horea-hemiballism rarely. Moreover, generalized chorea-ballism associated with nonketotic hyperglycemia in diabetes mellitus is very rare, so it has not been reported in Korean literature. Although the precise pathophysiologic mechanisms of these disorders are still poorly understood, deficiency of gamma aminobutyric acid (GABA) in nonketotic hyperglycemia or reduced GABAnergic inhibition by striatal lesion may increase inhibitory output to subthalamic nucleus. These result loss of pallidal inhibition and produce contralateral hemichorea-hemiballism. The striatal lesions, such as transient ischemia with reactive astrocytosis or small amount of petechial hemorrhage, are related with changes of magnetic resonance image (MRI) findings presumably. We report a diabetic old woman who developed generalized chorea-ballismus as a very rare complication of nonketotic hyperglycemia. Her brain MRI showed high signal intensity in left lentiform nucleus and right pallidum on T1 weighted images and low signal intensity in bilateral putamen on T2 weighted images with highly enhanced corresponding lesions on T1 weighted enhancement images.

Abstract PDF: BACKGROUND
In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. MATERIAL AND METHOD: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. RESULTS: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. CONCLUSION: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

Abstract PDF: BACKGROUND
The purpose of this study was to evaluated the usefulness of diffusion-weighted magnatic resonance imaging for monitoring the response to radiation therapy in metastatic bone marrow of the spines. MATERIALS AND METHOD: Twenty-one patients with metastatic bone marrow of the spine were examined with MRI. Diffusion-weighted and spin-echo MRI were performed in 10 patients before and after radiation therapy with or without systematic chemotherapy, and performed in 11 patiemts after radiation therapy alone. Follow up spin-echo and diffusion-weighted MRI were obtained at 1 to 6 months after radiation therapy according to patients' condition. The diffusion-weighted imaging sequence was based on reversed fast imaging with steady-state precession(PSIF). Signal intensity changes of the metastatic bone marrows before and after radiation therapy on conventional spin-echo sequence MRI and diffusion-weighted MRI were evaluated. Bone marrow contrast ratios and signal-to-noise ratio before and after radiation therapy of diffusion-weighted MRI were analyzed. RESULTS: All metastatic bone marrow of the spinal bodies were hyperintense to normal bone marrow of the spinal bodies on pretreatment diffusion-weighted MRI and positive bone marrow contrast ratio(p<0.001). and hypointense to normal spinal bodies on posttreatment diffusion-weighted MRI and negative bone marrow contrast ratio(p<0.001). The signal to noise ratio after treatment decreased comparing with those of pretreatment. Decreased signal intensity of the metastatic bone marrows on diffusion-weighted MRI began to be observed at average more than one month after the initiation of the radiation therapy. CONCLUSION: tThese results suggest that diffusion-weighted MRI would be an excellent method for monitoring the response to therapy of metastatic bone marrow of the spinal bodies. However, must be investigated in a larger series of patients with longer follow up period.

Abstract PDF: MR findings in nine patients(three female, six male) with neuroBehcet's disease were retrospectively analyzed. NeuroBehcet's disease was diagnosed on the basis of typical clinical symptoms. Involved site, pattern, signal intensity, and contrast enhancement pattern on MRI were evaluated. In addition, follow up MR imaging was performed in four patients. The midbrain(7/9), internal capsule(7/9), pons(6/9), thalamus(6/9), basal ganglia(5/9), middle cerebella peduncle(4/9), medulla oblongata(2/9), and subcortical white matter(2/9) are involved on MRI. The size of lesions were 1cm to 3cm and their margin was ill-defined and patchy. Inhomogeneous high signal intensity on the T2-weighted images and low signal intensity on T1-weighted images was seen respectvely. In four of nine cases, there was focal enhancement. On follow up MR imaging, improvement or recurrance of the lesions was found. Also in two cases of follow up cases there was artophy in brainstem and/or middle cerebellar peduncles. In conclusion, MR imaging with systemic clinical symptoms is useful for diagnosing neuro-Behcet's disease.

Abstract PDF

Internuclear ophthalmoplegia is a conjugated gaze disorder characterized by impaired adduction on the side of a lesion involving the medial longitudinal fasciculus with dissociated nystagmus of the other abducting eye. Six patients with INO (who had clinical cerebrovascular diseases) underwent MR imaging and the results were as follows: 1. The MLF lesions were identified by MR imaging in 5 cases 2. The ratio of unilateral INO to bilateral INO was 5:1 3. The nature of lesions was infarction in 4 cases and hemorrhage in 1 case 4. The sites of MLE lesion were in the midbrain in 4 cases and in the pons in 1 case 5. All 5 cases of INO identified by MR imaging had other lesion sites in addition to MLE lesion.
