目的 :评价放射性核素显像在消化道出血检测和定位诊断的价值。方法 :采用99mTc RBC动态显像和99mTcO-4 异位胃粘膜显像。结果 :6例99mTc RBC显像有 4例阳性 ,定位与临床最后诊断均相符合。 6例异位胃粘膜显像阳性 2例 ,诊断为Meckel s憩室。结论 :99mTc RBC显像对消化道出血的检出和定位诊断具有实用价值 ,异位胃粘膜显像可选择性应用于临床疑诊Meckel s憩室并出血的小儿患者。
Objective: To evaluate the value of radionuclide imaging in the detection and localization of gastrointestinal bleeding. Methods: 99mTc RBC dynamic imaging and 99mTcO-4 ectopic gastric mucosa imaging were used. Results: There were 4 cases of 99mTc RBC imaging in 6 cases, which were consistent with the final clinical diagnosis. 6 cases of ectopic gastric mucosa were positive in 2 cases, diagnosed as Meckel s diverticula. CONCLUSION: 99mTc RBC imaging has practical value in detection and localization of gastrointestinal bleeding. Ectopic gastric mucosa imaging can be selectively applied to pediatric patients with clinically suspected Meckel s diverticulum and bleeding.
