Indication for, and valuation of computed tomography following anterior resection of the rectum.

During a controlled study, 55 patients who had an anterior resection of the rectum were thoroughly examined, including by computed tomography. The results verified the following statements: 1. The use of CT as a screening-method for early detection of local tumour recurrence following anterior resection of the rectum appears not to be justified. 2. CT is indicated: a) if there is a laboratory or clinical suspicion of recurrence, despite normal findings on proctoscopy; b) to clarify the question of extramural extension if recurrence has been established by proctoscopy. 3. Following anterior resection of the rectum, CT normally demonstrates no remarkable development of scar tissue, unless the anastomosis is inadequate. 4. Following anterior rectal resection every indefinable tissue thickening in the pelvis must be considered a possible tumour recurrence and must be further investigated by needle biopsy.

Gd-DTPA enhanced MR imaging of the breast in patients with postoperative scarring and silicon implants.

Sixty patients with postoperative scarring with (30) or without (30) silicon implants have been examined by magnetic resonance (MR) with Gd-diethylenetriamine pentaacetic acid. The 60 patients consisted of 28 patients with obvious normal or abnormal findings and of 32 diagnostically difficult patients, who were referred to MR because of uncertain mammographic and/or clinical findings. Scarring older than 6 months postoperatively did not enhance noticeably, whereas scarring younger than 6 months postoperatively enhanced variably (nonsignificant, borderline, or significant). Since all carcinomas larger than the slice thickness enhance significantly (as also confirmed by other studies) contrast enhanced MR allowed an excellent discrimination between scarring older than 6 months and malignancy. Good visualization of the tissue around silicon implants proved to be another advantage of MR. When its use in the diagnostically difficult cases was analyzed, MR proved quite helpful in 23 of 32 cases by excluding or demonstrating malignancy.
