The diagnostic value of ultrasound and angiography is compared in 80 renal masses. Whereas the overall accuracy is approximately the same (95%), there are inherent limitations to both methods. As to sonography, the limiting factors consist of size, complex echopattern and lack of tissue distinction. Angiography, on the other hand, has its limitations in hypovascular tumors as well as in benign lesions simulating malignancy (abscess, hamartoma).
对80例肾肿块患者比较了超声和血管造影的诊断价值。尽管总体准确率大致相同（95%），但两种方法都有其固有的局限性。对于超声检查，限制因素包括肿块大小、复杂的回声模式以及缺乏组织分辨能力。另一方面，血管造影在低血供肿瘤以及模拟恶性肿瘤的良性病变（脓肿、错构瘤）中也存在局限性。
