[Measurement and differential demonstration of renal blood flow by computer angiography (author's transl)].
A new computer-aided x-ray technique is presented which, unlike conventional cine- or video-densitometry, allows a high-resolution quantitative display of the parameters of renal blood flow as so-called 'functional images'. The parameters include blood flow velocity and local perfusion of the kidney. This technique, which we call computer angiography, has decisive advantages; the functional images provide more, and more rapid, information on renal blood flow dynamics than can be obtained by the qualitative evaluation of a series of pictures. The clinical relevance of computer angiography is illustrated by a nephrotic syndrome, polycystic disease and a hypernephroma.
