RATIONALE AND OBJECTIVES Contrast-enhanced computed tomography (CT) images of canine renal cortex were analyzed to determine if the heterogeneous pixel intensity patterns met the requirements for fractal analysis and if the heterogeneity could be quantified by a fractal dimension, Df. METHODS Contrast-enhanced CT images were obtained after injection of iodipamide ethyl ester (IDE), a vascular marker, or iohexol, a freely filtered interstitial marker, into the catheterized renal artery of an… CONTINUE READING
