BACKGROUND Percutaneous nephrolithotomy (PCNL) is performed on a routine basis for the rapid and efficient removal of large caliceal stones. After percutaneous puncture, rigid dilators or an inflatable balloon are used to dilate the nephrostomy tract to allow access to the collecting system for stone removal. Little is known of the acute impact of tract(More)
PURPOSE To determine diagnostic accuracy of four-channel multi-detector row computed tomography (CT) in emergency room and inpatient populations suspected of having acute pulmonary embolism (PE) who prospectively underwent both CT and pulmonary arteriography (PA). MATERIALS AND METHODS Patients referred for PA to assess suspected PE were eligible.(More)
OBJECTIVE The purpose of our study was to determine the incidence of cysts in and adjacent to the lesser tuberosity and their association with rotator cuff abnormalities and subcoracoid impingement. MATERIALS AND METHODS A retrospective review of 1,000 consecutive MRI examinations of the shoulder was performed by consensus of two radiologists. Cysts were(More)
OBJECTIVE The purpose of this study was to determine the accuracy of IV contrast-enhanced MDCT and MRI for evaluation of the severity and cause of neural foraminal stenosis in patients with cervical radiculopathy. SUBJECTS AND METHODS Eighteen patients with cervical radiculopathy prospectively underwent contrast-enhanced MDCT and MRI. Contrast-enhanced(More)
We retrospectively identified all children with acute hip pain who underwent pelvic magnetic resonance (MR). Children with septic hip or history of trauma were excluded; the remaining children with signs of infection (fever, >38 degrees C; leukocytosis, >12 x 10(9)/L; or elevated erythrocyte sedimentation rate [ESR], >30 mm/h) comprised the study group.(More)
OBJECTIVES To report a retrospective series of 130 Chinese patients with penoscrotal extramammary Paget's diseases (EMPD), with a long-term follow-up, and thus improve the diagnosis and therapy of this disease. PATIENTS AND METHODS The history, clinical presentation, pathology, treatment, and prognosis of 130 patients were analysed. All cases were(More)
White matter (WM) lesions are the classic pathological hallmarks of multiple sclerosis (MS). However, MRI-based WM lesion load shows relatively poor correlation with functional outcome, resulting in the "clinico-radiological paradox" of MS. Unlike lesion based measures, volumetric MRI assessment of brain atrophy shows a strong correlation with functional(More)
OBJECTIVE The purpose of this article is to evaluate the relationship between apparent diffusion coefficient (ADC) values, tumor volume, and total Gleason grade in patients with prostate cancer before radical prostatectomy. MATERIALS AND METHODS A total of 110 patients with prostate cancer who had undergone endorectal prostate MRI at 1.5 T before radical(More)
OBJECTIVE This study was performed to determine whether a modified version of the classic STIR sequence provides similar information about the integrity of the rotator cuff tendon as the commonly used fat-suppressed T2-weighted fast spin-echo sequence. SUBJECTS AND METHODS Sixty-one consecutive MRI examinations of the shoulder in 57 patients were(More)
