Angiographic Magnetic Resonance Color Composites of the Normal Brain and Its Vasculature

Vascular magnetic resonance imaging (MRI) has become an important noninvasive adjunct to conventional cerebral MRI studies. To detect parenchymal changes associated with vascular anomalies, optimal diagnostic evaluation requires the comparison of both spin-echo and angiographic gradient-echo MRIs. To compress image data into a single 24-bit color image possessing the combined tissue contrast characteristics of both conventional spin-echo "black-blood" images and flow-sensitive gradient-echo "bright-blood" images, the red-green-blue color model and computer-based image-processing software were used to generate composites of MRI sets in which blood appears bright red while many stationary tissues possess near-natural colors. This technique may have potential applicability to human cerebrovascular MRI.
