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.[1]

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, they usually show intermediate-to-high signal intensity, with central hyperintensity indicative of extensive necrosis. Hemorrhage is common and foci of calcification may be present.[2]
