A comparative diagnostic study was carried out on 40 patients with pathologically proven renal malignancies which were staged both by angiography and CT. CT is more accurate than angiography for the detection of both perirenal and pararenal extension of the primary tumour (T-staging), and angiography is only slightly superior to CT in the evaluation of intravascular extension of the malignancy. The diagnostic performance of CT is clearly superior to angiography in detecting malignant lymphatic spread (L-staging) and distant metastases (M-staging). CT is, therefore, becoming the primary diagnostic approach for the staging of renal malignant tumours.
对40例经病理证实的肾恶性肿瘤患者进行了一项对比诊断研究，这些患者均通过血管造影和CT进行分期。在检测原发性肿瘤的肾周和肾旁扩展（T分期）方面，CT比血管造影更准确，而在评估恶性肿瘤的血管内扩展方面，血管造影仅略优于CT。在检测恶性淋巴转移（L分期）和远处转移（M分期）方面，CT的诊断性能明显优于血管造影。因此，CT正成为肾恶性肿瘤分期的主要诊断方法。
