| Research Abstract |
Using an equivalent cross-relaxation rate (ECR) imaging (ECRI), we observed the correlation between ECR values and tissue characterization of rat submandibular gland. ECR values at 5 ppm were correlated with cellular density, whereas ECR values at 19 ppm were correlated with the degree of extracellular matrices. The normal organization of liver tissues showed high ECR value, whereas liver tissues with hepatitis or liver cirrhosis showed lower ECR values. Among liver biochemical tests, values for platelet, albumin, bilirubin and ChE were closely related to ECR values. Therefore, ECRI is a potentially useful method for liver function by MRI.
