Assessment of liver oxygenation with BOLD MRI at 3T. Feasibility study
نویسندگان
چکیده
Introduction Liver biopsy is the gold standard for the liver fibrosis evaluation in patients affected by chronic liver disease. In healthy livers the vascular input is provided by the portal vein and hepatic artery, with the portal vein representing the main source of blood supply and normally the oxygenation of the liver is carefully auto-regulated. As hepatic fibrosis progresses it is thought the liver parenchyma become hypoxic which drives an increase in the relative arterial supply which has been observed with many different techniques.

Feasibility of BOLD Magnetic Resonance Imaging of Lung Tumors at 3T
Introduction Significant progress has been made in early detection and therapy for non-small cell lung cancer (NSCLC). However, lung cancer remains the leading cause of cancer death. Better characterization of lung tumors will allow for individualized therapy. There is increasing evidence that hypoxia in tumors predicts poor outcome for many tumor types including lung malignancies, most notably...
متن کاملRetinotopic mapping with spin echo BOLD at 7T.
For blood oxygenation level-dependent (BOLD) functional MRI experiments, contrast-to-noise ratio (CNR) increases with increasing field strength for both gradient echo (GE) and spin echo (SE) BOLD techniques. However, susceptibility artifacts and nonuniform coil sensitivity profiles complicate large field-of-view fMRI experiments (e.g., experiments covering multiple visual areas instead of focus...
متن کاملAssessment of segmental myocardial blood flow and myocardial perfusion reserve by adenosine-stress myocardial arterial spin labeling perfusion imaging.
PURPOSE To determine the feasibility of measuring increases in myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) on a per-segment basis using arterial spin labeled (ASL) magnetic resonance imaging (MRI) with adenosine vasodilator stress in normal human myocardium. MATERIALS AND METHODS Myocardial ASL scans at rest and during adenosine infusion were incorporated into a routine...
متن کاملDynamic contrast-enhanced MRI in the liver at 3T with dual-input pharmacokinetic model analysis
Introduction DCE-MRI has been widely used at 1.5T in a variety of organs and tissues. The aim of this study was to assess the feasibility of DCE-MRI in the liver at 3T, taking into account the challenges of 3T systems, and performed in such a way as to allow a dual-input pharmacokinetic analysis, separating the perfusion contributions from the hepatic artery and portal vein. To our knowledge, t...
متن کاملChanges in human fetal oxygenation during maternal hyperoxia as estimated by BOLD MRI.
OBJECTIVE Changes in blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) signal are closely related to changes in fetal oxygenation. In this study, we aimed to investigate the changes in human fetal oxygenation during maternal hyperoxia by using the non-invasive BOLD MRI technique. METHOD Eight healthy pregnant women in gestational week 28 to 34 were included. With the use of...
