[Morphometric differentiation of tumor and inflammation in angiography (author's transl)].
The angiographic differential diagnosis of malignant, benign and inflammatory lesions should be facilitated by mathematical analysis of the underlying vascular structure. A rotating screen with parallel lines -- especially developed for this purpose -- is used for the first time to verify statistically essential criteria in tumor diagnosis. Random samples are taken from 2 kidneys with severe inflammatory lesions and 1 hypernephroma in order to extract mathematical indices for fluctuation of caliber, vascular avulsion, change of direction and diameter. The index for the flucutation of caliber is the single most important criterion to differentiate the vascular structure of tumor and inflammation.
