MR imaging and histopathology of cartilage tumors

The MR imaging-pathologic correlation of cartilaginous bone tumors and the value of intravenously administered Gd-DTPA enhanced MR imaging was studied. The MR studies were retrospectively reviewed. Thirty-seven cases were examined with 0.5 T and 1.0 T scanner and all cases were pathologically proved. We discussed the following MR findings: signal intensities of tumors, Gd-DTPA features, morphological findings, and associated findings. Hyaline cartilage tumors showed low signal intensity on T1-weighted images and very high signal intensity on T2-weighted images. Lobulated marginal enhancements were recognized in chondrosarcomas. This may be an important finding to suspect chondrosarcoma. (author)
