OBJECTIVE The purposes of this study were to determine the feasibility of diffusion-weighted imaging (DWI) with a single-shot echo-planar sequence and parallel technique for depicting endometrial cancer and to examine the role of this technique in preoperative assessment. SUBJECTS AND METHODS A total of 31 patients were recruited for MRI evaluation of(More)
The purpose of this study was to assess the diagnostic accuracy and pitfalls of MR imaging in preoperative staging of cervical cancer. Magnetic resonance imaging was performed to determine the tumor staging for 41 patients with cervical carcinoma emphasizing tumor size, parametrial invasion, vaginal invasion, and lymph node metastases. According to the(More)
OBJECTIVE This study was an attempt to identify key CT features that can potentially be used to differentiate between lipid-poor renal angiomyolipoma and renal cell carcinoma (RCC). MATERIALS AND METHODS We conducted an analysis of patients who received nephrectomy or renal biopsy from 2002 to 2011 with suspected RCC. We included tumors smaller than 7 cm(More)
BACKGROUND To evaluate the accuracy of helical computerized tomography urography (CTU) in diagnosing urinary tract disease. METHODS We collected 102 patients who underwent CTU from March 2001 to September 2002. The clinical symptoms of these patients included: flank pain or hematuria, which were clinically suggestive of urinary system disorders. All(More)
The purpose of this study was to compare the efficacy of two laxatives, castor oil and bisacodyl, in the routine bowel preparation of outpatients for intravenous urography (IVU). We used castor oil in patients undergoing IVU for 1 month, and then used bisacodyl in patients undergoing IVU for another month. Two uroradiologists, unaware of the method of bowel(More)
We describe herein an extramedullary plasmacytoma (EMP) in the retroperitoneal space, an uncommon manifestation of plasma cell tumor occurred in a rare site. Only a few cases have been reported in a search of English-language literature. In this report, the imaging appearances of the tumor in both computed tomography (CT) and sonography will be presented.(More)
Renal cell carcinoma (RCC) is the most common malignant renal tumor in adults. The kidney can usually be adequately imaged with real-time ultrasound (US) scanners. To summarize the ultrasonographic manifestations of RCC, we reviewed 78 patients with pathologically proved RCC. Within a per iod of 5 years , sevent y-eight patients were found to have renal(More)
This study prospectively evaluated the diagnostic value of unenhanced computerized tomography (CT) urography in patients with acute renal colic. Fifty-nine patients with clinical manifestations of acute renal colic underwent unenhanced helical CT to evaluate urinary tract abnormalities. Reformatted three-dimensional CT urography was performed in all(More)
BACKGROUND The purpose of this prospective study was to evaluate the feasibility of replacing intravenous urography (IVU) with unenhanced computed tomography (CT) as the first line diagnostic modality for acute renal colic in the emergency department. METHODS In the 1-year study period, 82 patients who presented themselves to the emergency room with acute(More)
