[Magnification technique in abdominal angiography (author's transl)].

The authors describe the requirements for improved information with magnification in abdominal angiography. The low effect of the microfocus tube limits its use in conventional technique mainly because of the grid. Magnification technique combined with high sensitive screens and no grid will compensate for the low effect of the tube. Unsharpness due to motion is more marked with magnification technique but is in practical work of little importance. A useful technique for renal and pancreatic angiography is discussed.
