MRI

An MRI uses magnetic fields but it is a different type of image than what is produced by computed tomography (CT) and produces detailed images of the body. Like computed tomography (CT), a contrast agent may be injected into a patient’s vein to create a better picture.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.
