Cerebral Metastases Clinical Trial
Official title:
Prospective Study of Predictive Value of Dynamic Contrast Enhancement Magnetic Resonance Imaging With Gadolinium on the Response of a Cerebral Tumor to a Treatment With Gamma Knife
Hypothesis: the pattern of MRI contrast enhancement after gadolinium injection is different
in tumors that respond well to gamma knife.
We are going to acquire sequential T1-weighted images of brain lesions before, during and
after injection of Gd-DTPA. This will be repeated before and after a treatment with gamma
knife. We will then analyse our results to see if there are common enhancement
characteristics between lesions that will respond well to the radiosurgery treatment.
Response will be clinically assessed by tumor volume as determined by MRI approximately 4 to
6 months after treatment.
