Overview
MRI is an imaging method using signal detection from spinning protons exposed to a magnetic field and offers superior soft tissue contrast to and better evaluation of tumor size, spread, and neurovascular involvement than CT. It also has a valuable role in follow-up for the evaluation for tumor recurrence.
MRI
On T1-weighted images of MRI, leiomyosarcomas has the following descriptions:
- large infiltrating myometrial mass of heterogeneous hypointensity with irregular margins.
On T2-weighted images, tumors have the following features:
- Intermediate-to-high signal intensity, with central hyperintensity indicative of extensive necrosis.
- Hemorrhage is common and calcification may be present.[1]
