Localization tests including TC-scans, scintigraphy with 131I-radiolabelled metaiodobenzylguanidine and ultrasound have been performed in 68 patients with diagnosed pheochromocytoma. Diagnosis was based on clinical symptoms and increased catecholamines and/or their metabolites excretion with the urine. Proper diagnosis with CT-scans was 97%, scintigraphy--92%, and ultrasound--93%; false negative results in scintigraphy amounted to 8% (3 patients) and 5% (3 patients) in case of ultrasound. CT-scans were free of such errors. False positive diagnosis was made in 2 (3%) patients with CT-scans and in 1 (2%) patient tested with ultrasound. These results suggest that pheochromocytoma may be precisely localized with non-invasive techniques, especially CT-scans.
对68例已确诊的嗜铬细胞瘤患者进行了包括CT扫描、131I标记的间碘苄胍闪烁显像和超声检查在内的定位检查。诊断依据临床症状以及尿中儿茶酚胺和/或其代谢产物排泄增加。CT扫描的正确诊断率为97%，闪烁显像为92%，超声为93%；闪烁显像的假阴性结果为8%（3例患者），超声为5%（3例患者）。CT扫描无此类错误。CT扫描有2例（3%）患者出现假阳性诊断，超声检查有1例（2%）患者出现假阳性诊断。这些结果表明，嗜铬细胞瘤可用非侵入性技术精确定位，尤其是CT扫描。
