The development of contrast agents for ultrasound has significantly extended its clinical applications, particularly in the detection and characterization of focal liver lesions. Real-time evaluation of the vascular phase currently can be achieved by combining new microbubble-specific methods with second-generation contrast agents. The enhancement pattern(More)
The appearance of hepatocellular carcinoma (HCC) with contrast-enhanced ultrasound (CEUS) in the vascular phase is described and evaluated as to whether the enhancement pattern correlates with the degree of cellular differentiation. One hundred four HCCs were prospectively evaluated with CEUS using coherent-contrast imaging (CCI) and SonoVue with a low(More)
OBJECTIVE Giant cell arteritis (GCA) may involve the aorta. Retrospective studies have demonstrated a higher prevalence of aortic aneurysm among patients with GCA compared with the general population. We investigated the prevalence of aortic aneurysm in a cohort of patients with biopsy-proven GCA using a defined protocol and assessed whether persisting(More)
The objective of this study was to assess the efficacy of contrast-enhanced ultrasonography (CEUS) with SonoVue R to evaluate the response to percutaneous treatment (ethanol injection/radiofrequency) of hepatocellular carcinoma in comparison with spiral computed tomography (CT) immediately and 1 month after treatment. Forty-one consecutive cirrhotic(More)
The purpose of this study was to compare the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) with spiral computed tomography (SCT) for the characterization of focal liver lesions (FLL) and to determine the degree of correlation between the two techniques. Seventy-seven FLL (45 hepatocellular carcinomas; 12 metastases; ten hemangiomas; two(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)
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)
Hepatocellular carcinoma (HCC) is the leading cause of death in liver cirrhosis. Ultrasound (US) is widely accepted as the screening imaging modality of choice for HCC in patients with a history of chronic liver disease. However, the US characteristics of HCCs are non-specific and thus, other imaging techniques or biopsy are usually necessary to(More)
OBJECTIVE The purpose of this pictorial essay is to review the color Doppler sonographic features of Budd-Chari syndrome. CONCLUSION Combining color and spectral data, sonography provides hemodynamic and anatomic information about vessel patency and collateral vessel formation. The diagnosis of Budd-Chari syndrome is based on the involvement of hepatic(More)
