Abstract
This study aimed to evaluate magnetic resonance (MR) imaging appearances of 11 gastrointestinal
stromal tumors in the abdomen and pelvis and compared them with some histological
findings. Gastrointestinal stromal tumor showed nonhomogeneous signal intensity and
included hemorrhage in large tumors. Gastrointestinal stromal tumors showed a wide
variety of enhancement, and contrast enhancement of the tumor was consistent with
mitosis index as well as the largest diameter of the tumor. Contrast-enhanced MR imaging
may be useful in the assessment of tumor activity.
