OBJECTIVE Assessment of disease extension and activity is crucial to guide treatment in Crohn's disease. The objective of the current cross-sectional study was to determine the accuracy of MR for this assessment. DESIGN 50 patients with clinically active (n = 35) or inactive (n = 15) Crohn's disease underwent ileocolonoscopy (reference standard) and MR.(More)
With the advent of filmless radiology, it becomes important to be able to distribute radiologic images digitally throughout an entire hospital. A new approach based on World Wide Web technologies was developed to accomplish this objective. This approach involves a Web server that allows the query and retrieval of images stored in a Digital Imaging and(More)
PURPOSE To assess the value of chemical shift gradient-echo (GRE) magnetic resonance (MR) imaging with the fast low-angle shot (FLASH) technique to detect fatty metamorphosis in hepatocellular carcinoma (HCC). MATERIALS AND METHODS Sixty-three cirrhotic patients with 69 HCCs underwent MR imaging at 1.0 T with chemical shift GRE technique. Both(More)
PURPOSE Our goal was to compare in-phase (IP) and opposed-phase (OP) GRE and conventional SE sequences in T1-weighted (T1-W) imaging of the liver and to evaluate chemical shift GRE imaging in characterizing liver/lesions for fat content. METHOD IP and OP T1-W GRE with fast low angle shot (FLASH) technique and T1-W SE sequences were compared in 162(More)
PURPOSE To evaluate proton fat-water chemical shift fast low-angle shot magnetic resonance (MR) imaging for differentiation of fat-containing hyperechoic liver nodules from hyperechoic liver nodules without a fatty component. MATERIALS AND METHODS T1-weighted fast low-angle shot fat-water chemical shift gradient-echo MR imaging was performed in 96(More)
OBJECTIVE Unsedated gastroscopy is unpleasant for some patients. The identification of factors related to tolerance would permit the selection of patients for sedation. The aim of the present study was to identify these factors. METHODS Five hundred and nine patients underwent diagnostic gastroscopy after the administration of topical pharyngeal(More)
Thirty-six consecutive patients with advanced hepatocellular carcinoma and chronic liver disease were randomly allocated to two groups: group I included 20 patients who were treated with 10 mg bid. tamoxifen and group II with 16 non-treated patients. The two groups were homogeneous according to clinical and analytical data. Survival curves in the(More)
A two-site enzyme-linked immunosorbent assay was used to quantitate levels of basic fibroblast growth factor in the vitreous from 36 patients undergoing vitrectomy for a variety of retinal conditions, including proliferative diabetic retinopathy, macular pucker, and retinal detachment with and without proliferative vitreoretinopathy. Basic fibroblast growth(More)
Spiculated breast lesions may be caused by both benign and malignant processes, including sclerosing adenosis, postsurgical scar, radial scar, tuberculosis (rare), posttraumatic oil cysts, infiltrating ductal carcinoma, ductal carcinoma in situ (rare), infiltrating lobular carcinoma, and tubular carcinoma. Mammographically, such lesions are often similar,(More)
