PURPOSE The goal of this study was to evaluate the diagnostic accuracy of a software program that automatically analyzes the liver surface to diagnose significant fibrosis, by comparing it to the subjective analysis of a radiologist and to transient elastography (Fibroscan(®)). PATIENTS AND METHODS One hundred fourteen patients with chronic liver disease(More)
OBJECTIVES The objectives of this study are to describe the standardization and dissemination of dynamic contrast-enhanced ultrasound (DCE-US) for the evaluation of antiangiogenic treatments in solid tumors across 19 oncology centers in France and to define a quality score to account for the variability of the evaluation criteria used to collect DCE-US(More)
BACKGROUND Experience was gained management of intra-gastric migration of adjustable gastric banding. METHODS From July 1996 to January 2003, 4236 patients who underwent laparoscopic adjustable gastric banding were proposed for routine follow-up. Gastrograms were performed in case of band adjustment. Radiological controls and endoscopy were performed(More)
PURPOSE To retrospectively determine whether magnetic resonance (MR) volumetry of rectal cancer is a reproducible method for predicting disease-free survival (DFS) in patients with locally advanced low or midrectal tumors who undergo combined chemotherapy and radiation therapy (CRT) before total mesorectal excision. MATERIALS AND METHODS The institutional(More)
OBJECTIVES To compare adrenal gland volume in septic shock patients and control patients by using semi-automated volumetry. METHODS Adrenal gland volume and its inter-observer variability were measured with tomodensitometry using semi-automated software in 104 septic shock patients and in 40 control patients. The volumes of control and septic shock(More)
PURPOSE To evaluate the accuracy of computed tomography (CT) scan imaging in distinguishing lymphedema from deep venous thrombosis (DVT) and lipodystrophy (lipedema) in patients with swollen legs. MATERIAL AND METHODS CT scans of the lower limbs were performed in 55 patients with 76 swollen legs (44 lymphedemas, 12 DVT and 20 lipedemas). Thirty-four(More)
PURPOSE To evaluate the sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of ultrasonography (US), Doppler US, and laboratory findings in the diagnosis of appendicitis. MATERIALS AND METHODS A total of 125 consecutive patients suspected of having appendicitis were prospectively included for US appendiceal(More)
To determine the relationship between quantitative Doppler parameters of portal, hepatic, and splanchnic circulation and hepatic venous pressure gradient (HVPG), variceal size, and Child-Pugh class in patients with alcoholic cirrhosis, we studied forty patients with proved alcoholic cirrhosis who underwent Doppler ultrasonography, hepatic vein(More)
OBJECTIVES The impact of recruitment maneuvers on gas exchange, hemodynamics, alveolar recruitment, and hyperinflation is highly variable among patients with acute respiratory distress syndrome. The objective was to determine whether differences in lung morphology, defined as differences in the pulmonary distribution of aeration loss, predict the response(More)
PURPOSE To evaluate rectal cancer volumetry in predicting initial neoadjuvant chemotherapy response. MATERIALS AND METHODS Sixteen consecutive patients who underwent neoadjuvant chemotherapy (CX) before chemoradiotherapy (CRT) and surgery were enrolled in this retrospective study. Tumor volume was evaluated at the first magnetic resonance imaging (MRI),(More)
