Abstract

Small focal areas of intestinal infarction were produced experimentally in mice by two techniques: (1) intussusception and (2) suture strangulation of a loop of jejunum. The radionuclide technetium 99m diphosphonate (99mTc-diphosphonate) was subsequently administered intravenously, and abdominal scans were obtained. The scans demonstrated focal infarcted lesions accurately, and every positive scan was associated with an area of infarction, as demonstrated by pathologic examination. However, negative scans did not definitely exclude an area of infarction: in the intussuception study there were five false negative scans in 25 animals, and in the loop ligation study there were two false negative scans in 28 animals. The technique may have clinical application in such intestinal diseases as necrotizing enterocolitis in infancy in which early diagnosis of small areas of necrosis is currently difficult by clinical and radiologic methods.
