title: [Sonographic and roentgenologic course controls following radiotherapy of retroperitoneal neoplasms].
abstract: Twelve patients with retroperitoneal tumors were examined sonographically and roentgenologically before and after radiation therapy. The sonograms were evaluated quantitatively by planimetry. Nine cases revealed analogous results in roentgenologic and in sonographic examinations. In three cases sonography revealed a tumor regression which was not verifiable with X-rays. In consideration of these results, sonography is used by us as a primary method for examination of retroperitoneal tumors during the follow-up control.
