The usefulness of ultrasonography (US) in the diagnosis of aldosterone-producing adenoma(s) (APA) was compared with computed tomography (CT) and adrenal scintigraphy in 13 patients. The initial examination with US could demonstrate four of seven right APA. Repeat examinations later in two patients whose tumors were initially not detectable did reveal a tumor in one patient. On the other hand, two left APA were delineated on the initial trial. The other seven left APA, except two small APA in one patient, could be delineated during repeat US examinations performed on other days. With CT, all APA were detected during the first or second trial except for the smallest one. The rate of localization by adrenal scintigraphy with dexamethasone pretreatment was 11 of 13 patients. CT had the highest localization rate. However, US was shown to be useful in the localization diagnosis of APA on repeat examinations with a high delineation rate comparable to CT.
在13例患者中，将超声检查（US）与计算机断层扫描（CT）及肾上腺闪烁显像术在醛固酮瘤（APA）诊断中的效用进行了比较。初次US检查可显示7例右侧APA中的4例。最初未检测到肿瘤的2例患者后来复查时，有1例发现了肿瘤。另一方面，初次检查时就勾勒出了2例左侧APA。除1例患者中的2个小APA外，其他7个左侧APA在其他日期进行的重复US检查中得以勾勒出来。CT检查时，除最小的APA外，所有APA在首次或第二次检查时均被检测到。经地塞米松预处理的肾上腺闪烁显像术的定位率为13例患者中的11例。CT的定位率最高。然而，在重复检查时，US在APA的定位诊断中显示出有用性，其勾勒率高，可与CT媲美。
