[Resolution of small vessels in abdominal magnification angiography (author's transl)].

In order to assess the resolution of small vessels in abdominal magnification angiography, the influence of iodine concentration and magnification ratio was analyzed in a model experiment using 0.1 mm focus and lanthanoxibromide screens MR 600. The experiment showed that the resolution increases with both increasing magnification ratio and iodine concentration. Assuming that there was no movement of the object, the vessels of 80 micrometer could be resolved in three- to five-fold magnification.
