Ultrasound (US) was compared with surgical findings in 98 patients with carcinoma of the ovary undergoing follow-up laparotomy after chemotherapy. US had an overall accuracy of 94% in the pelvis, with only small and sheetlike lesions escaping detection. It was more sensitive than clinical examination. Overall accuracy for the liver was 91% with very few false-positive results. For the peritoneal cavity in general, however, accuracy was low, with even large masses escaping detection. Ascites is reliably detected (accuracy of 97%) but is a poor indicator of peritoneal involvement. US is a useful noninvasive complement to laparoscopy in the follow-up of patients with carcinoma of the ovary.

The selection of levels for tomographic sections of the kidneys during intravenous urography has previously been based on empirical observation. Three hundred abdominal computed tomographic scans were analyzed for the anteroposterior (AP) midpoints of the kidneys and their relationship to the patient's AP abdominal diameter. A graph for selection of tomographic levels was generated and compared with existing methods. These guidelines enable a more objective approach to urographic tomography.
