[Recurrence of rectal cancer in computerized tomography].

Abstract

In contrast to conventional methods of x-ray diagnosis, recurrence of a rectum carcinoma may be visualized directly by means of computerized tomography. CT criteria of a tumor relapse are discussed. Based on own cases, it is shown that the method is usually employed too late. CT as follow-up examination should be used as a routine procedure in order to establish an early diagnosis of tumor recurrence.
