OBJECTIVE To evaluate the radiographic and MR appearance of idiopathic synovial osteochondromatosis of the hip. MATERIALS AND METHODS Radiographs and MR images of 15 patients with idiopathic synovial osteochondromatosis of the hip were assessed. The former were analysed in terms of the presence of 1) juxta-articular calcified and/ or ossified bodies, 2)(More)
OBJECTIVE The purpose of this study was to assess the usefulness of magnetic resonance (MR) arthrography of the glenohumeral joint in the diagnosis of adhesive capsulitis. METHODS MR arthrography of the glenohumeral joint was performed in 16 patients with arthroscopically proven adhesive capsulitis and 11 controls. Thickness of the joint capsule and(More)
The aim of the study was to evaluate whether MR Imaging of the knee at 30° and 55° of flexion can improve the diagnosis of anterior cruciate ligament and menisci injuries compared to arthroscopy and imaging during extension of the knee joint. Knee joints from 40 patients with clinical suspicion of an anterior cruciate ligament (ACL) rupture were examined(More)
PURPOSE We evaluated follow-up magnetic resonance (MR) images for osteoid osteoma treated with percutaneous radiofrequency ablation (RFA). MATERIALS AND METHODS Sixteen patients with osteoid osteoma treated with RFA underwent follow-up MR imaging. The protocol included T1, T2 and contrast-enhanced (CE) T1-weighted images with fat saturation at each visit(More)
BACKGROUND Magnetic resonance imaging (MRI) is well accepted for the contemporary diagnosis of venous malformation (VM), providing hemodynamic and anatomic information on the lesion, including its relationship with surrounding tissues and organs. STUDY DESIGN A total of 196 clinically suspected VM patients were reviewed retrospectively to assess the(More)
To evaluate the effects of facet joint injection (FJI) reducing the need for percutaneous vertebroplasty (PVP) in cases of vertebral compression fracture (VCF). A total of 169 patients who were referred to the radiology department of our institution for PVP between January 2011 and December 2014 were retrospectively evaluated. The effectiveness of FJI was(More)
OBJECTIVE We compared polymethylmethacrylate (PMMA) leakage from vertebral bodies in osteoporotic compression fractures with and without intravertebral vacuum clefts (IVCs) on computed tomography (CT) after vertebroplasty. METHODS Percutaneous vertebroplasty was performed in 59 patients, comprising 36 compression fractures with IVCs in 33 patients and 49(More)
Serial changes of bone density in 26 femora and 22 tibiae that underwent leg lengthening by distraction osteogenesis were investigated by measuring the pixel value shown on a picture archiving and communication systems (PACS) monitor. The pixel value of the original cortex did not change significantly until the external fixator was removed. The pixel value(More)
OBJECTIVE The objective of our study was to describe the imaging findings of Kimura's disease in the soft tissue of the upper extremity. CONCLUSION Kimura's disease should be considered as a possible diagnosis when a partially or poorly defined subcutaneous mass of high signal intensity on T1- and T2-weighted images with homogeneous enhancement,(More)
OBJECTIVE To estimate and compare radiation exposure and intervention time during lumbar epidural steroid injection (ESI) 1) under different practitioners and methods with continuous fluoroscopic monitoring, and 2) under one practitioner with different methods and monitoring. MATERIALS AND METHODS We consecutively recruited 804 patients who underwent(More)
