Metastatic Intra‐Axial Neoplasia

The role of MRI imaging in the metastatic work‐up is to detect the spread of tumor to the brain parenchyma, and define the location. Intravenous contrast (gadolinium‐DTPA) provides the greatest sensitivity for detecting brain lesions and is almost always indicated except when there is no intravenous access. This unit presents a for imaging intra‐axial brain metastases and specific modifications are discussed for the case of metastatic brain tumors demonstrating evidence of hemorrhage. The sequences described in this unit are based on 1.5 T scanner (Echospeed GE Medical Systems, Milwaukee, Wisconsin), but can be expected to be equally applicable to other field strengths and scanners from other manufacturers.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145372/1/cpmia0301.pd
