OBJECTIVES We aimed to develop a model based on noninvasive variables for the prediction of clinically significant portal hypertension (CSPH) and of esophageal varices (EV) in patients with compensated liver disease. METHODS Sixty patients with compensated liver cirrhosis diagnosed by histology were included in the training set. All patients had physical(More)
Temporomandibular joint (TMJ) dysfunction is a common condition that is best evaluated with magnetic resonance (MR) imaging. The first step in MR imaging of the TMJ is to evaluate the articular disk, or meniscus, in terms of its morphologic features and its location relative to the condyle in both closed- and open-mouth positions. Disk location is of prime(More)
BACKGROUND To study the sonographic pattern of autosomal recessive polycystic kidney disease (ARPKD) in early adulthood in order to identify imaging criteria to diagnose this disease and to distinguish between recessive and autosomal dominant polycystic kidney disease (ADPKD) in that age group. METHODS An abdominal ultrasound was performed on four ARPKD(More)
PURPOSE To estimate the sensitivity and specificity of ultrasonography (US) in the diagnosis of autosomal dominant polycystic kidney disease (ADPKD) types 1 and 2, as compared with those of genetic linkage analysis. MATERIALS AND METHODS A renal US and DNA analysis for ADPKD was performed in 319 patients who were at risk, 161 of whom were younger than 30(More)
Multidetector computed tomography (CT) is the choice technique for preoperative evaluation of living renal donors. Living donor transplantation, as opposed to cadaveric donation, is the best option for recipient and graft survival. The need for kidney transplantation has undergone exponential growth over the past 40 years, and cadaveric donations are(More)
OBJECTIVE To determine whether nephrolithiasis is associated with radiographic changes in renal papillae. MATERIALS AND METHODS We performed a prospective study comparing papillae attenuation in a stone-forming group (SFG) and a healthy stone-free control group (CG). The SFG inclusion criteria were active stone disease diagnosed by abdominal computed(More)
This study evaluated the role of duplex Doppler sonography in the diagnosis of VOD of the liver after bone marrow transplantation. Sixteen patients with clinical criteria of VOD were studied. The final diagnosis was achieved by transjugular liver biopsy, and the hepatic venous pressure gradient was measured during the procedure to estimate portal pressure.(More)
PURPOSE The aim of this prospective study was to determine whether sonography with a hydration test to induce diuresis can be used to reliably differentiate between excretory renal obstruction and renal sinus cysts. METHODS We performed sonographic examination of all patients diagnosed with minimal or moderate obstruction of the intrarenal collecting(More)
PURPOSE To evaluate whether CT-identified Randall plaques can be used to foresee the recurrence of stone disease (SD); to define a cut point that could identify a high-risk population. MATERIALS AND METHODS A retrospective study of patients attended for SD from January 2004 to December 2009 was conducted. Study population was patients with a first episode(More)
OBJECTIVES To determine the incidence of computed tomography (CT) identifiable Randall plaques in a CT explored population; to determine the clinical relevance of this radiological finding by a 7-year follow-up; to determine a cut point to identify a population with high risk of developing calcium stone disease (SD). MATERIALS AND METHODS Retrospective(More)
