Abstract
The purpose of this study is the improvement in evaluation of the inflammation extent on the scintigraphic imaging, by utilizing statistical indices (Inflammation Projection Ratio - IPR, skewness, kurtosis and Mean Pixel Value - MPV). Image analysis was performed by means of an Interactive Data Language (IDL) tool. Twelve patients were referred for a radionuclide (Tc99m- Leukoscan) scan, by a GE Healthcare gamma camera, on the suspicion of an infectious lesion in the extremities. The findings of the study are that pathological tissues have a higher IPR index (3.12 to 4.32) compared to normal tissue (∼ 1). Furthermore, MPV, skewness and kurtosis differ significantly (> 5%) from normal to inflammable extremities. As a conclusion, image processing provides effective information in the structure and facilitates diagnosis semi-quantitatively.
