[Image quality in intravenous digital subtraction angiography of renal vessels].

Visualisation of the renal arteries and image quality of intravenous DSA were evaluated in 62 patients. The left renal artery is visualised less well than overlying more frequently the right renal artery because of gas in the stomach and colon. IV DSA is not adequate for visualisation of the subsegmental arteries, and cannot be used for tumor angiography. It is not possible to prove that central venous injection technique is superior to peripheral venous injection. Patients must be carefully prepared as is necessary for the urogram. Examination is carried out using Buscopan and a compression device.
