摘要
目的 :评价SPECT显像在美克耳憩室并出血诊断中的价值。材料和方法 :对 17例疑为美克耳憩室并出血的患儿进行了高锝酸盐 (99mTcO4- )腹部平面显像 ,2例作了断层显像。结果 :阴性显像 6例 ,5例经临床表现及相关检查排除美克耳憩室 ,1例经手术证实为美克耳憩室。阳性显像 11例 ,9例经手术及病理证实为美克耳憩室 ,1例为空肠及其系膜巨大海绵状血管瘤 ,1例为回肠管状重复畸形。SPECT显像对美克耳憩室诊断的敏感性、特异性和准确性分别为 90 .0 %、71.4%和 82 .4%。结论 :SPECT显像简单易行 ,是诊断美克耳憩室并出血的首选影像学方法 ,加采断层显像可以提高敏感性。
Purpose: The purpose of this study is to assess the value of SPECT scintigraphy in the diagnosis of Meckel's diverticulum (MD) with hemorrhage. Materials and Methods: 99m TcO 4 - imaging was performed on 17 hospitalized children with a history of gastrointestinal hemorrhage and abdominal pain. Tomographic study was undertaken on 2 cases. Results: Among 6 cases of negative imaging, MD was ruled out in 5 by clinic data and other examinations. One MD was confirmed by surgery. 11 cases had positive imaging. In surgery, 9 were proved to be MD, one jejunal huge hemangioma, and one ileum malformation duplicated. The sensitivity, specificity and accuracy of radionuclide imaging for MD were found to be 90.0%, 71.4% and 82.4% respectively. Conclusion: Pertechnetate abdominal scintigraphy is simple and safe. It should be the first choice for diagnosis of MD, and SPECT imaging could improve sensitivity.
