Figure Lengend Snippet: FIGURE 2 (A) Schematic illustration of the scanning technique employed to visualize hindlimb muscles of experimental rats; (B) topographic location of vastus lateralis (VL), vastus intermedius (VI), rectus femoris (RF) and vastus medialis (VM) muscles; (C) a normalized ultrasonogram containing individual muscles with a green line illustrating a possible positioning of a polygonal region of interest (ROI) used for determining echotextural characteristics of RF parenchyma; and (D) a summary of digital image analysis performed with ImageProPlus ® computer software (Mean, mean numerical pixel values; Std Dev, pixel heterogeneity; X Min and X Max, minimal and maximal pixel intensity values within ROI; and Sum, a total number of pixels encapsulated by an ROI; a red graph is a pixel distribution histogram with pixel intensity values along the x-axis and the numbers of detected pixels of specific intensities on a y-axis).
Article Snippet: Image analysis based on arbitrarily chosen clusters of echointensity values (EI bands) The regions of interest in the images containing the largest cross-sectional area of the rectus femoris were delineated using a polygonal tool and subjected to the bitmap analysis using ImageProPlus® analytical software (Media Cybernetics Inc., Experimental Biology and Medicine Published by Frontiers Society for Experimental Biology and Medicine09 Rockville, MD, United States).
