摘要
Gastrointestinal bleeding scintigraphy performed with Tc-99m-labeled autologous erythrocytes or historically with Tc-99m-sulfur colloid has been a clinically useful tool since the 1970s. This article reviews-the history of the techniques, the different methods of radio-labeling erythrocytes, the procedure, useful indications, diagnostic accuracy, the use of SPECT/CT and CT angiography to evaluate gastrointestinal bleeding, and Meckel diverticulum imaging. The causes of pediatric bleeding are discussed by age.
