|ClinicalTrials.gov Identifier: NCT00001719|
Recruitment Status : Completed
First Posted : November 4, 1999
Last Update Posted : March 4, 2008
This study will use magnetic resonance imaging (MRI) to examine blood flow patterns in the arteries and veins of the liver and abdomen. It will 1) determine the best way to measure blood flow in these vessels, and 2) make detailed measurements of the blood flow patterns of these vessels. Information about normal liver blood flow may help explain the role of blood flow in liver disease.
Normal healthy volunteers 18 years of age and older may be eligible for this study. They will undergo MRI-a diagnostic tool that uses a strong magnetic field and radio waves to show structural and chemical changes in tissue and the speed of moving blood. The patient lies on a stretcher inside a metal cylinder (the scanner) for 1 to 1.5 hours and will be required to lie very still for 10 to 15 minutes at a time. Blood pressure, heart rate, breathing and the amount of oxygen in the fingertip are measured during the scan.
