BLOOD SIGNAL SUPPRESSED CONTRAST ENHANCED MAGNETIC RESONANCE IMAGING
First Claim
Patent Images
1. A method of magnetic resonance imaging (MRI) with blood signal suppression comprising:
- a. applying a pulse sequence having a preparatory section designed to modify signal from organ tissue differently than blood pool signal followed by an inversion RF pulse;
b. waiting for a period of time that is sufficiently long to allow organ tissue with dissimilar T1 relaxation times to have disparity in signal yet short enough so that blood signal has greater negative magnetization than the tissues of interest, wherein the wait time is sufficiently short to result in blood pool signal suppression compared with some tissues of interest but does not result in a black blood image; and
c. acquiring MRI data from the region-of-interest with a phase sensitive reconstruction.

Abstract
Methods for achieving suppression of blood pool signal to image contrast-enhanced organs and vascular walls using magnetic resonance (MR) imaging technology. MRI data is then acquired with phase sensitive reconstruction so that blood pool signal is suppressed compared with the tissues of interest.
