Radiotherapy response of cerebral metastases quantified by serial MR imaging

J Neurooncol. 1994;21(2):171-6. doi: 10.1007/BF01052901.

Abstract

A patient with cerebral metastases, treated with radiotherapy, underwent serial gadolinium-enhanced MR imaging. The MR images were quantified using home developed software to evaluate the changes in volumes of tumor mass and edema after radiotherapy (mean precision of the quantification technique less than 5%). The decrease in tumor volume and edema observed after radiotherapy preceded clinical improvement. The presented technique can be used to accurately assess, more directly than using clinical scales, the effect of putative therapies.
