We report the MR imaging findings in a 44-year-old man with a low-grade synovial sarcoma. There was a right-sided epidural and paravertebral mass, widening of the ipsilateral neural foramen at the L4-L5 level, and focal erosion of the right superior articular process of the L5 vertebra. The mass was relatively homogeneous, hyperintense to muscle and(More)
OBJECTIVE The objective of our study was to investigate the clinical feasibility of ultrasound elastography for assessing patients with lateral epicondylosis and to establish an objective and quantitative method of elastographic measurement in the affected tendon. SUBJECTS AND METHODS A total of 97 symptomatic and 89 asymptomatic common extensor tendons(More)
The aim of our study was to analyze the imaging findings of femoroacetabular impingement (FAI). Eight consecutive patients [age range, 19-46 years (mean, 28.6 years); M/F ratio=7:1] who underwent operation for FAI were analyzed. We analyzed bump, acetabular retroversion and protrusion, and osteoarthritis in the radiographs. In MR arthrography, we analyzed(More)
The aim of our study was to examine the locational distribution of paraspinal structures on MRI and to determine any predictable parameters that may be used for the identification of transitional vertebra (TV). We enrolled 534 patients who underwent MRI of their lumbosacral spine. The locations of the paraspinal structures, such as aortic bifurcation (AB),(More)
OBJECT The authors evaluate the biomechanical properties of vertebral bodies (VBs) stabilized with calcium phosphate (CaP) cements for use in vertebroplasty in comparison with polymethylmethacrylate (PMMA). METHODS In the first phase of the study, 73 VBs (T3-L2; thoracic region [T3-8] and thoracolumbar region [T9-L2]) were collected from seven fresh human(More)
We assessed the fibrovascular ingrowth into porous orbital implant with MRI. Twelve cases underwent T1WI, T2WI, Gd-enhanced T1WI, and Short Tau Inversion Recovery (STIR) images. Gd-enhanced T1WI showed homogeneous enhancement (n=4), peripheral and posterior part enhancement (n=7), and anterior part enhancement (n=1) of implants. High signal intensity(More)
PURPOSE To evaluate the postoperative MR findings of healthy anterior cruciate ligament (ACL) grafts, which were confirmed by second look arthroscopic examination. MATERIALS AND METHODS We evaluated 33 MR scans of 29 patients who underwent postoperative MR scans and second look arthroscopic examination (four patients underwent postoperative MRI twice)(More)
PURPOSE To evaluate magnetic resonance (MR) imaging for the discrimination between low-grade chondrosarcoma and enchondroma. MATERIALS AND METHODS MR images of 34 patients who were confirmed with low-grade chondrosarcoma or enchondroma were retrospectively reviewed. After review of medical records, MR findings in 18 patients with low-grade chondrosarcoma(More)
Hoffmann’s syndrome is a hypothyroid myopathy presenting as muscle stiffness and hypertrophy. It is a rare complication of hypothyroidism. MRI features of this syndrome have seldom been described in the literature. We present a case of Hoffmann’s syndrome in a 34-year-old man who underwent lower extremity contrast-enhanced MRI. MRI can demonstrate the(More)
OBJECTIVE The aim of this study was to describe MR findings of osteofibrous dysplasia. MATERIALS AND METHODS MR images of 24 pathologically proven osteofibrous dysplasia cases were retrospectively analyzed for a signal intensity of the lesion, presence of intralesional fat signal, internal hypointense band, multilocular appearance, cortical expansion,(More)
