MR of Brain Metastases
Since its introduction, MR proved to be an effective method of diagnosis of intracranial tumors. Its sensitivity in the detection of intraaxial neoplasm, particularly low grade glioma, is now considered to be superior to that of CT scan. Generally accepted mode of MR evaluation of intracranial neoplasms is a spin-echo sequence with short and also prolonged TR/TE intervals. MR presentation of metastatic intraaxial lesions on Tl and T2 weighted sequences, as correlated with histological diagnosis is the subject of this investigation.
