Fig. 3From: A pilot study in intraparenchymal therapy delivery in the prostate: a comparison of delivery with a porous needle vs standard needleLeft (a): T1 Gadolinium injection image with standard needle (red arrow) and porous needle (black arrow) pointing to the linear needle image entering the prostate from lower edge of prostate. White arrow depicts infusate movement to the urethra. Yellow arrow depicts channels of infusate from the injection site to the urethra. Right (b): Gadolinium concentration map showing outflow moved from the injection site to urethra (dark oval upper center) and subcapsular region in both figures. Note larger porous needle infusate distribution and concentration (red) on right compared to standard needle on leftBack to article page
