肾上腺影像学检查定位诊断价值的比较

自１９５８年５月－１９９４年１月行肾上腺皮质与髓质肿瘤手术共６５１例，其中７５例术前同时进行了ＩＶＵ、Ｂ超、ＣＴ及γ照相检查，其肿瘤定位符合率分别是２．７％、８８％、８６．７％及７３．３％。我们体会对肾上腺肿瘤可采用Ｂ超和ＣＴ定位，这二项检查可相互补充，我们根据其中任何一项阳性定位手术探查尚未遇假阳性结果。当这二项检查定位有困难时选用γ照相则有助于肾上腺肿瘤的定位。ＭＩＢＧ对多发性嗜铬细胞瘤，肾上

The diagnostic evaluation of IVU,B-type ultrasonograpby, CT and scintigraphy in three entities of adrenal tumors

From May 1958 to January 1994, 651 patients with tumors of adrenal cortex and medulla were treated surgically. Preoperative IVU,B-type ultrasonography,CT and scintigraphy were carried out simultaneously in 75.The conformable rates of these modalities were 2,7%, 88%, 86.7%and 73.3% respectively. As a routine,we usually employ sonography and CT in localizing adrenic tumors as they can be mutually replenished. Surgical exploration always verified the positive localization of sonography or CT.Only when difficulty was encountered with these two methods,scintigraphy was added. There are special merits with MIBG imaging examination for the localization of multi-pheochromocytoma, extra-adrenal pheochromocytoma and matastatic malignant pheochromocytoma.
