目的：探讨Ｂ型超声、ＣＴ及（或）同位素检查对肾上腺醛固酮瘤定位诊断的互补作用。方法：对疑醛固酮瘤者作Ｂ超检查２３８例，其中１４１例同时作过ＣＴ检查，２７例作为核素检查。将各种检查与病理对照，再把其中的假阴性与假阳性病例分别与其他两种检查相对照。结果：发现三种检查对漏诊（假阴性）单瘤具用很强的互补性，而对同侧双瘤则均未能幸免漏检其中之一。对误诊（假阳性）亦有很好的互补性，且本组核素无假阳性，但其样本嫌小（仅２７例）。结论：通过对比研究可以明确采用何种检查方法属最佳选择。
Objective: To explore the complementary role of B-mode ultrasound, CT and/or isotope examination in the diagnosis of adrenal aldosteronoma. METHODS: A total of 238 cases of suspected aldosteronoma were examined by B-ultrasound, of which 141 cases had CT examinations at the same time and 27 cases were used as radionuclide examinations. The various examinations were compared with pathology, and the false negative and false positive cases were compared with the other two examinations. RESULTS: It was found that the three tests had strong complementarity for missed (false negative) single tumors, and none of the two tumors on the same side were missed. Misdiagnosis (false positives) is also very complementary, and there are no false positives in this group of radionuclides, but the samples are too small (only 27 cases). Conclusion: The comparative study can clearly determine which test method is the best choice.
