Angiomiolipomi renali sanguinanti.Rilievi con TC

To describe our experience in three cases of abdominal haemorrhage caused by bleeding renal angiomyolipomas, which were studied with Computed Tomography (CT). MATERIALS AND METHODS: A retrospective study carried out at our archives identified 3 patients (aged 58.6 on average) with renal angiomyolipomas clinically manifested with acute abdomen and haemorrhage. The patients underwent an emergency CT scan of the abdomen. One patient also under-went a subsequent renal angiography. All patients had surgery and histological characterizations of the renal lesions. RESULTS: The CT study on all three patients allowed detection of a lesion in the kidneys with inhomogeneous density due to haemorrhage.…

Precision measurement of the K S meson lifetime with the KLOE detector

Using a large sample of pure, slow, short lived K0 mesons collected with KLOE detector at DaFne, we have measured the KS lifetime. From a fit to the proper time distribution we find tau = (89.562 +- 0.029_stat +- 0.043_syst) ps. This is the most precise measurement today in good agreement with the world average derived from previous measurements. We observe no dependence of the lifetime on the direction of the Ks.

MR imaging of pancreatic changes in patients with transfusion-dependent β-thalassemia major

OBJECTIVE. The aim of this study was to evaluate MR imaging changes of the pancreas in patients with transfusion-dependent β-thalassemia major. SUBJECTS AND METHODS. Twenty patients with transfusion-dependent β- thalassemia major were examined using MR imaging at 0.5 T, with spin-echo T1- weighted, fast spin-echo T2-weighted, and gradient-echo T2*-weighted sequences. Image analysis was performed to assess pancreas-to-fat signal intensity ratios for all pulse sequences. Pancreatic exocrine and endocrine function and serum ferritin levels were assessed. Twenty healthy volunteers underwent MR imaging with the same three sequences and served as a control group. RESULTS. The pancreas-to-fat sign…
