摘要
对７６例消化道出血患儿作￣（９９ｍ）Ｔｃ腹部显像，经随访确诊１２例，其中腹部有异常放射性浓聚者７例，由手术诊断美克耳憩室６例、肠重复畸形１例、无异常放射性浓聚者５例，证实为空肠粘膜下血管畸形，未成熟畸胎瘤等。其对异位胃粘膜所致小儿下消化道出血有较高的诊断符合率，是一种安全、简便、有效的检测手段。
eventy six child patients with intestinal bleeding were exanuned by 99mTc-pertechnetateabdominal scintigraphy and 12 of them were dia gnosed by follow-up. 7 cases showed positiveimaging wich included 6 surgically confirmed Meckel’s diverticuli cases and 1 duplication cyst. The other 5 cases werethe negative imaging.They are confirmed to be angiodeformity of jejunalmucosa and unmature teratoma etc. These res ults indicated that the accuracy of abdomin alimaging was high in the diagnosis of children’s intestinal hemorrhage caused by ectopic gastricmucosa.Therefore,it is a safe, convenient,and effective means in diagnosing of these diseases
