[Radiation dose in renal magnification angiography compared with conventional angiography (author's transl)].

Measurements of skin dose, integrated skin dose area, and integral dose in combined conventional and magnification renal angiography using lanthanoxibromide screens MR 600 and carbon fibre plate in filmchangertop have been made. The mean skin dose in magnification technique was 0.56 rad./film with focus-skin distance of 35 cm, FFD 1 m, 85-90 kV and sagittal diameter of abdomen of 20 cm. The combination of angiographic technique with and without magnification and the use of a high-sensitivity receiving unit makes it possible to keep the total skin dose per investigation (8.5 rad.) within the limits accepted in conventional abdominal angiography.
