The conclusions drawn from a prospective survey of 500 patients examined by cholecystography (OCG) and ultrasound (UCG) are presented. First, both procedures were found to be highly accurate in detecting calculi, with false-negative rates of 1%. Secondly, if OCG is abandoned in favour of UCG, most acalculous adenomyomatosis (and many polyps) will not be diagnosed. If acalculous as well as calculous disease is regarded as clinically important, fluoroscopic OCG is the examination of choice. However, if a clinician wishes solely to find or exclude stones the investigations are equally accurate. Thirdly, since some calculi and some acalculous disease will be missed by either technique, serious consideration should be given to the further investigation of all gallbladders considered normal by either examination. A protocol is described which, though unorthodox, enables a decision on the status of the gallbladder to be made on a single visit to the radiology department.
本文介绍了对500例患者进行胆囊造影（OCG）和超声检查（UCG）的前瞻性调查得出的结论。首先，发现这两种检查方法在检测结石方面都非常准确，假阴性率为1%。其次，如果放弃OCG而采用UCG，大多数无结石性腺肌增生症（以及许多息肉）将无法被诊断出来。如果无结石性和有结石性疾病都被视为具有临床重要性，荧光透视OCG是首选检查方法。然而，如果临床医生只想发现或排除结石，这两种检查同样准确。第三，由于两种技术都会遗漏一些结石和一些无结石性疾病，因此对于两种检查均认为正常的所有胆囊，应认真考虑进一步检查。本文描述了一种方案，该方案虽非正统，但能在单次前往放射科就诊时就胆囊状况做出决定。
