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)
iii Abstract In early 2010, the Long-Baseline Neutrino Experiment (LBNE) science collaboration initiated a study to investigate the physics potential of the experiment with a broad set of different beam, near-and far-detector configurations. Nine initial topics were identified as scientific areas that motivate construction of a long-baseline neutrino(More)
We present a comprehensive and systematic approach for skin detection. We have evaluated each component of several colour models , and then we selected a suitable colour model for skin detection. Such approach is well-known in the machine learning community as attribute selection. After listing the top components, we exemplify that a mixure of colour(More)
Peroneal nerve palsy in traumatic knee dislocations associated with multiple ligament injuries is common. Several surgical approaches are described for this lesion with less-than-optimal outcomes. The present case represents the application of plasma rich in growth factors (PRGF) technology for the treatment of peroneal nerve palsy with drop foot. This(More)
Background There is little information on the individual risk of screen-detected cancer in women over successive participations. This study aimed to estimate the 10-year cumulative breast cancer detection risk (ductal carcinoma in situ and invasive carcinoma) in a population-based breast cancer screening program according to distinct protocol strategies. A(More)
We conducted this study to determine the associated factors and outcomes of community-acquired primary bacteremia (PB), to describe the most frequently isolated microorganisms, the antibiotic resistance pattern, and to guide the most appropriate antibiotic treatment. A total of 1,640 community-acquired bacteremia cases in nonneutropenic adults were(More)
Evaluation of efficacy of intravenous flecainide to revert supraventricular arrhythmias to sinus rhythm in patients with respiratory insufficiency. Comparative randomized prospective trial. ICU in a University Hospital 30 patients with acute respiratory insufficiency or acute exscerbation of chronic respiratory insufficiency and supraventricular(More)
A general class of Lorentzian metrics, M0 × R 2 , ·, ·z = ·, ·x + 2 du dv + H(x, u) du 2 , with (M0, ·, ·x) any Riemannian mani-fold, is introduced in order to generalize classical exact plane fronted waves. Here, we start a systematic study of their main geodesic properties: geodesic completeness, geodesic connectedness and multiplicity or causal character(More)
