Abstract

This study investigates which filters are preferred by radiologists for diagnosing particular pathologies found in digitally acquired renal studies. Four types of filters are applied to twenty digitally acquired renal arteriograms demonstrating a wide distribution of pathologies. Three radiologists, who knew the pathology of the patients, examined representative unfiltered and filtered images from each study and then judged whether the filtered image helped demonstrate the pathology. The Butterworth filter was the most versatile filter, the statistical difference filter was most useful for separating overlapping vessels in arterial phase images and the two edge enhancement filters were least useful, only aiding diagnosis 20%. Overall, filtering was thought by the radiology panel to improve diagnosis for only 65% of the ten abnormal cases in this study.
