[Digital subtraction angiography in the diagnosis of kidney carcinomas].
We report on the results of a comparison of intravenous and intraarterial digital subtraction angiography (iv and ia-DSA) with conventional angiography in patients with known renal masses. Whereas more than 80% of the tumours were diagnosed via IV-DSA, none of the benign renal cysts were identified. The overall detection rate, therefore, is 65% in all patients (n = 21) of the study group. The value of ia-DSA as a time sparing procedure, saving film-cost and contrastmedia, is discussed. The diagnostic accuracy of selective renal angiograms in digital and conventional technique yields equal results in our comparative study.
