OBJECTIVE To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600). A total(More)
PURPOSE To retrospectively identify apparent diffusion coefficient (ADC) values of pediatric abdominal mass lesions, to determine whether measured ADC of the lesions and signal intensity on diffusion-weighted (DW) images allow discrimination between benign and malignant mass lesions. MATERIALS AND METHODS Approval for this retrospective study was obtained(More)
OBJECTIVE The purpose of this study was to use MRI and anatomic correlation in cadavers to delineate the anatomic features of the distal attachment of the brachialis muscle. MATERIALS AND METHODS MRI was performed on 13 cadaveric elbows. The MRI findings were compared with those in anatomic sections and histologic preparations. The brachialis muscle of(More)
OBJECTIVE As part of the lateral ligament complex of the elbow, the annular ligament has an adjunctive role in stabilizing the proximal radioulnar joint. Knowledge of the anatomy of this ligament may enhance our understanding of its functional role in maintaining integrity of the elbow joint in fracture and dislocation. The purpose of this study is to(More)
Osteopoikilosis (OPK) is a rare benign sclerosing disease of the skeleton and inherited as an autosomal dominant trait. OPK is associated with inflammatory rheumatic disorders, such as rheumatoid arthritis, scleroderma, reactive arthritis and familial Mediterranean fever (FMF). We report a rare case of OPK coexistent with ankylosing spondylitis and FMF. The(More)
Pleomorphic xanthoastrocytoma is a rare, cortically based, partially cystic astroglial tumour with a strongly enhancing solid mural nodule. We report an 11-year-old boy with a pleomorphic xanthoastrocytoma in the contralateral hemisphere to that affected by Sturge-Weber syndrome. This unique case supports the association between Sturge-Weber syndrome and(More)
Ionizing radiation is known to induce mutations and cell transformations, predominantly by causing single-strand and double-strand DNA breakage, thereby leading to chromosome instability and carcinogenesis. The aim of this study was to evaluate genotoxic effects in hospital staff exposed to low-dose ionizing radiation in comparison with a selected control(More)
Psoas abscess secondary to tuberculous spondylodiskitis is usually a complication of thoracolumbar vertebrae disease. The psoas abscess may be difficult clinically to diagnose because of its rarity, insidious onset of the disease, and nonspecific clinical presentation. We report multidetector CT and MR imaging findings of a psoas abscess secondary to(More)
The anatomy of the peroneus longus and tibialis posterior tendons is well described in literature from both anatomy and radiology. Though a slip connecting these two structures is described in the anatomic literature, its existence has not been confirmed with magnetic resonance imaging (MRI). In this study in a cadaver, such a connection is(More)
