title: Utility and limits of an imaging follow-up in evaluation of response and evolution of cerebral tumors after radiotherapy.
abstract: CT scans of 110 patients with malignant gliomas treated with radiotherapy, postoperative or alone, were reviewed. Our aim was to assess the utility and limits of an imaging follow-up in evaluating tumor response to treatment and evolution. We have tried to define the densitometric parameters of tumors in various evolutive phases, with special emphasis on variations of contrast enhancement during time. CT scan findings were compared with clinical and therapeutic data.
