Left renal vein entrapment: a frequent feature in children with postural proteinuria

In most Asian subjects with postural proteinuria, ultrasonic imaging and Doppler flow scanning disclose entrapment of the left renal vein in the fork between the aorta and the superior mesenteric artery. Little information is available on the possible occurrence of left venal rein entrapment in European subjects with postural proteinuria. Renal ultrasound with Doppler flow imaging was therefore performed on 24 Italian or Swiss patients with postural proteinuria (14 girls and ten boys, aged between 5.2 years and 16 years). Signs of aorto-mesenteric left renal vein entrapment were noted in 18 of the 24 subjects. In conclusion, aorto-mesenteric left renal vein entrapment is common also among European subjects with postural proteinuria.

Differential diagnosis of CT focal liver lesions using texture features, feature selection and ensemble driven classifiers

The aim of the present study is to define an optimally performing computer-aided diagnosis (CAD) architecture for the classification of liver tissue from non-enhanced computed tomography (CT) images into normal liver (C1), hepatic cyst (C2), hemangioma (C3), and hepatocellular carcinoma (C4). To this end, various CAD architectures, based on texture features and ensembles of classifiers (ECs), are comparatively assessed.
