本文复习一组5年内应用各种放射照相技术在诊断上的正确性问题,特别强调定位的假阳性率。应用定位技术其后果各异,乃取决于患的是肾上腺髓质的疾病还是肾上腺皮质的疾病,以及病人是否曾应用药物准备过。肾上腺定位的方法:①腹部X线平片的敏感度低,只能诊断已钙化的肾上腺。②腹膜后充气造影目前已不采用。③排泄性尿路摄影用来鉴别与肾上腺肿瘤有关的疾病。④肾上腺静脉造影,除用作肾上腺肿块的定位外,还可确定原发肿瘤是否已侵入静脉。由于造影剂过量注入肾上腺静脉,可引起肾上腺梗塞和肾上腺功能丧失,故目前已用来做为肾上腺栓塞治
This article reviews the diagnostic accuracy of a group of radiography techniques within a 5-year period, with particular emphasis on the false positive rate of localization. The consequences of applying the positioning technique vary depending on whether it is an adrenal medulla disease or an adrenocortical disease, and whether the patient has ever used a drug. Adrenal positioning methods: 1 The sensitivity of the abdominal radiograph is low, and only the calcified adrenal gland can be diagnosed. 2 retroperitoneal inflation angiography is currently not used. 3 Drainage urography is used to identify diseases associated with adrenal tumors. Adrenal venography, in addition to the location of adrenal masses, can also determine whether the primary tumor has invaded the vein. Due to excessive injection of contrast agent into the adrenal vein, which can cause adrenal infarct and loss of adrenal function, it has been used as a treatment for adrenal embolization.
