Abstract
The authors, from their experience in 60 patients, demonstrate that technetium-99m-labelled red blood cell scintigraphy is a sensitive (91%) and specific (76%) diagnostic procedure with a high predictive value, when both positive (81%) and negative (92%). It is preferable to and more cost-effective than selective angiography as a first-line diagnostic test for occult gastrointestinal bleeding.
摘要
作者根据他们对60例患者的经验表明，锝-99m标记的红细胞闪烁扫描术是一种敏感（91%）且特异（76%）的诊断方法，具有较高的预测价值，阳性预测值为81%，阴性预测值为92%。作为隐匿性胃肠道出血的一线诊断试验，它比选择性血管造影更可取且更具成本效益。
