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 MRI,Leiomyosarcomas commonly manifest as large infiltrating mass of heterogeneous hypo intensity on T1-weighted images,with irregular and ill-defined margins.On T2-weighted images,they usually show intermediate-to-high signal intensity, with central hyper intensity indicative of extensive necrosis.Hemorrhage is common and foci of calcification may be present.
