PURPOSE To correlate intra voxel incoherent motion (IVIM) diffusion parameters of liver parenchyma and hepatocellular carcinoma (HCC) with degree of liver/tumor enhancement and necrosis; and to assess the diagnostic performance of diffusion parameters vs. enhancement ratios (ER) for prediction of complete tumor necrosis. PATIENTS AND METHODS In this IRB approved HIPAA compliant study, we incl...

An efficient measurement methodology is proposed to construct the scattering parameters of a multi-port device using a four-port vector network analyzer (VNA) without the external un-terminated ports. By using the four-port VNA, the reflected waves from the un-terminated ports could be minimized. The proposed method significantly enhances the accuracy of the S-parameters with less number of mea...

This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from full knowledge of the albedo operator at the boundary of a bounded domain of interest. We present optimal stability results on the reconstruction of the absorption and scattering parameters for a given error in the measured albedo operator.

introduction: cytomegalovirus (cytome-galovirus: cmv) infection is a common cause of morbidity and mortality in patients who are the candidate for liver transplant. serological monitoring of individuals rece-iving and giving the liver transplant is necessary for prevention, early diagnosis and treatment strategies and reducing the prevalence of infection. the aim of this study was to assess the...

Serum concentrations of fazadinium were measured in eight patients with cirrhosis and eight patients with total biliary obstruction who underwent abdominal surgery. A biexponential decay of the concentration was observed after a single i.v. injection of fazadinium. A two-compartment open model was used in the pharmacokinetic analysis of the data. The pharmacokinetic parameters were compared wit...

background: recent studies demonstrated that resveratrol has many therapeutic effects on liver disorders. resveratrol significantly increased survival after liver transplantation, decreased fat deposition, necrosis, and apoptosis which induced by ischemia in wistar rats. it provided liver protection against chemical, cholestatic, and alcohol injury. resveratrol can improve glucose metabolism an...

effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...

Objective(s):  Protective effects of different extracts and essential oil from Pimpinella anisum           L. seeds were examined against carbon tetrachloride (CCl4)-induced toxicity. The parameters such as serum transaminases, lactate dehydrogenase activity, hepatic glutathione content, liver lipid peroxidation and histopathological changes of liver were assessed as toxicity markers. In the in...
