The Use of Tuned Shape Window for the Improvement of Scars Imaging in Static Renal Scintigraphy in Children

Physiological renal processes are evaluated based on planar images registered by a gamma camera, SPECT or PET. However, detection of small disorders in standard planar scintigraphic imaging is difficult and sometimes impossible. The aim of the research conducted at Pomeranian Medical University is to increase the sensitivity of the method for detecting the areas of renal functional disorders called scarring. The image recorded as a result of the test was subject to digital processing. In that purpose, a novel window function was used for filter designing. Standard and processed images were presented to three independent experts. The diagnosis results were subject to statistical analysis. As a result, a large share of changes in diagnosis was reported in the total number of conducted tests, a strong correlation between positive evaluation of the role of processed images and a change in diagnosis as well as an increased possibility of kidney condition evaluation.
