A magnetic resonance (MR) image processing technique that uses a single color image for simultaneous presentation of spin‐echo information and its application to MR studies of the brain is described. Relaxation rate and proton‐density maps were calculated from 160 brain MR studies performed at 1.5 and 1.0 T with standard spin‐echo sequences. Maps were fused into single color images, with R1, R2. and proton density coded, respectively, by red, green, and blue. The possibility of standardizing the technique was evaluated. Comparative analysis of color and conventional MR images of white matter disease and brain tumors was performed to assess intra‐ and interob‐server variability. Unequivocal and reproducible chromatic characterization of normal brain structures and a variety of lesions was obtained. Intra‐and interobserver analysis showed that color images can be used as a diagnostic tool. The technique may provide a simplified and timesaving approach for interpretation and presentation of brain MR studies.
