Overview
MRI scan may be helpful in the diagnosis of gastrointestinal stromal tumor.
MRI
MRI is more accurate and sensitive than a CT scan for delineating rectal GISTs and in identifying liver metastasis, hemorrhage and necrosis.[1][2][1][2] Presence of necrosis, haemorrhagic and cystic change make appearances variable:
- T1:
- Low signal intensity solid component
- Enhancement is usually present, and predominantly peripheral in larger lesions
- T2: high signal intensity solid component
