Abstract

We investigated the relationship between pathological findings and MR images of 5 resected soft tissue tumors. These included desmoid, hemangioma, liposarcoma, schwannoma and malignant schwannoma. The increase of collagen was an important histological feature of tumors, and this was seen on MRI as a decrease in signal intensity, especially, on T2 weighted images. Minute amounts of fat tissue appeared as high intensity on T1 weighted images on MRI. This study suggested that MRI may reflect minute histological changes in the matrix of soft tissue tumors.
