Quantitative MR imaging method
Target Audience: Researchers and clinicians interested in quantitative MR imaging. Purpose: A patient receiving a typical MR exam can expect to lie in the scanner for as long as 45 min or so as the anatomy of interest gets repeatedly imaged, using a variety of tissue contrasts. The proposed approach allows the main MR parameters such as M0, T1, R2, R2′, B1 and B0 to be rapidly and quantitativel...
متن کاملEvaluation of superparamagnetic iron oxide for MR imaging of liver injury: proton relaxation mechanisms and optimal MR imaging parameters.
PURPOSE To investigate the proton relaxation mechanisms and the optimal MR imaging parameters in superparamagnetic iron oxide (SPIO)-enhanced MR imaging of liver injury. METHODS A liver injury model was created in the rat using carbon tetrachloride. The T1 and T2 relaxation effects of SPIO in normal and injured liver were estimated by ex vivo relaxometry. In vivo laser confocal microscopy of ...
متن کاملMr Imaging of the Liver Ii: Diseases
Hepatocellular carcinoma (HCC) is the most common primary cancer of the liver. The overall 5-year survival rate without any treatment is less than 5%.9 HCC is less frequent in Western countries than in the East or Southeast Asia. The incidence of HCC, however, is rising in Europe and North America.9, 38 In a recent study, the incidence of HCC in the United States increased from 1.4 per 100,000 ...
متن کاملAnalysis of Fluctuation in Cerebral Venous Oxygenation Using MR Imaging: Quantitative Evaluation of Vasomotor Function of Arterioles
PURPOSE Cerebral arteriolar vasomotor function plays an important role in brain health. Since respiratory changes in the partial arterial pressure of CO2 (PaCO2) cause arterioles to vasodilate or vasoconstrict, resting-state arteriolar vasomotion results in the fluctuation of venous blood oxygenation, which can be monitored by observing magnetic resonance (MR) signals. Focusing on the superior ...
متن کاملEvaluation of liver and kidney function in favism patients
Backgrounds: G6PD deficiency is the most common enzymopathy of red blood cells. The clinical symptoms of favism are jaundice, hematuria and haemolytic anaemia that seem to affect liver and kidney in long term. Thus we evaluate kidney and liver function of favism patients in an endemic area of the disease with a high rate of fava beans cultivation. Methods: This study was performed on favism pa...
