Biliary scintigraphy using 99mTc p-butyl acetanilidiminodiacetic acid (BIDA) was performed as part of the diagnostic evaluation on 96 patients with jaundice (serum bilirubin greater than 2 mg/dl) to assess its value in this group of patients. The results of scintigraphy revealed no obstruction to the flow of the scintigraphic agent into the duodenum in 54 patients, delayed appearance of the agent (normal upper limit 60 min) in the duodenum indicating partial obstruction in 22 patients, and complete obstruction of the duct demonstrated by absence of agent in the duodenum in 20 patients. The findings were correlated with the final diagnosis and the overall results show accuracy of 92.7%, sensitivity of 97.3%, and specificity of 89.8%. Biliary scintigraphy was thus found to be useful in differentiating nonobstructive, partially obstructive, and completely obstructive causes of jaundice.
采用99mTc对丁基乙酰苯胺亚氨基二乙酸（BIDA）进行胆道闪烁扫描，作为对96例黄疸患者（血清胆红素大于2mg/dl）诊断评估的一部分，以评估其在该组患者中的价值。闪烁扫描结果显示，54例患者的闪烁造影剂流入十二指肠无梗阻，22例患者十二指肠内造影剂出现延迟（正常上限为60分钟）提示部分梗阻，20例患者十二指肠内无造影剂显示胆管完全梗阻。将这些结果与最终诊断进行关联，总体结果显示准确率为92.7%，敏感性为97.3%，特异性为89.8%。因此，发现胆道闪烁扫描有助于鉴别黄疸的非梗阻性、部分梗阻性和完全梗阻性病因。
