Radiation-induced pelvic insufficiency fractures are a frequent complication of radiation therapy for uterine cervical cancer. Osteolysis and avascular necrosis of the femoral head were also diagnosed using MRI after radiation therapy.

PURPOSE: The purpose of this study was to evaluate the accuracy of the characteristic magnetic resonance imaging (MRI) findings of medial meniscal root tear in the coronal, sagittal and axial planes. METHODS: Thirty arthroscopically diagnosed patients who had undergone preoperative knee MRI were included in this study. They were compared to 30 age-matched patients with medial meniscus tears without root tears. The findings used for imaging analysis were as follows: the radial tear on the menisca

One of the tumors was located in C7. The other nine tumors were located in the thoracic spine, lumbar spine, and sacrum, three in each site. The characteristic findings included an expansile mass with heterogeneous low to intermediate signal intensity on the T2-weighted images (10/10), a curvilinear area of signal void on T1- and T2-weighted images (9/10), and cystic changes within the mass (4/10). Although no imaging feature was pathognomonic, MRI was found to be valuable in identifying the tum

Background The obesity paradox is a topic of increasing interest in oncology and epidemiology research. Although this phenomenon has been observed in melanoma patients receiving immune checkpoint inhibitors, little is known about its mechanism. We aim to investigate the prognostic value of obesity and its association with adiposity and systemic inflammation. Methods This retrospective study evaluates the data of patients who received pembrolizumab or nivolumab for unresectable or metastatic mela

OBJECTIVE: The objective of our study was to compare the indirect MR arthrographic findings of patients with adhesive capsulitis and patients without adhesive capsulitis. MATERIALS AND METHODS: Indirect MR arthrograms of 35 patients (21 women, 14 men; mean age, 50.1 years) diagnosed with adhesive capsulitis clinically were compared with indirect MR arthrograms of 45 patients (23 women, 22 men; mean age, 48.9 years) without adhesive capsulitis. Joint capsule thickness in the axillary recess and t

BACKGROUND: This study aimed to use a superthin, free superficial circumflex iliac artery perforator (SCIP) flap in functional surgery for treating subungual melanoma and to evaluate its outcomes. METHODS: Forty-one patients with primary subungual melanoma of less than or equal to 2-mm thickness who were treated with functional surgery were prospectively enrolled. After oncologic resection, a thin SCIP flap was harvested along the trans-superficial fat layer and transferred to the defect with fu

Isotropic 3D shoulder MR arthrography combined with a multiplanar reconstruction technique can help in the diagnosis of shoulder labral lesions as does 2D MR arthrography, but with shorter imaging times.

PURPOSE: To determine a new cutoff value that can further distinguish between the incomplete and complete discoid lateral meniscus (DLM). MATERIALS AND METHODS: Twenty-one cases of incomplete DLM and 42 cases of complete DLM without tear were included. In all, 105 patients with normal lateral menisci were included as a control group. We measured the ratio of the shortest width of the lateral meniscus to the longest width of the tibia (ratio 1) and the ratio of the shortest width of the medial me

BACKGROUND: Discoid lateral meniscus is more susceptible to tear than normal meniscus. A comparison study for tear types of discoid lateral meniscus between children and adults has not been reported. PURPOSE: To compare tear type of surgically proven discoid lateral meniscus between adults and children, and to analyze diagnostic performance for tear type of discoid lateral meniscus using magnetic resonance imaging (MRI). MATERIAL AND METHODS: Knee MR examinations of 53 children and 84 adults who

BRAF inhibitors were an effective therapeutic option for Korean patients with metastatic melanoma harboring a BRAF V600 mutation regardless of melanoma subtype (acral/mucosa versus cutaneous).

We established a reproducible technique to quantify lymph node enhancement that can distinguish between different agents. The differences in performance suggest that it is possible to optimize agent formulation for indirect sonographic lymphography.
