Characteristics of the clinically significant lesions that ARFI imaging detected and missed as a function of estimated histologic lesion volume and Gleason grade, color-coded by location in the anterior (blue) or posterior (red) region of the prostate. “Multifocal disease” is defined as a prostate having four or more cancerous foci. Note that ARFI did not miss any of the highest Gleason grade lesions (Gleason 8 and 9), and the majority of the missed clinically significant lesions had volumes <1.0 mL or were located in the anterior (blue). The numbers on the plots associated with some of the high-volume lesions indicate the absolute volumes of the lesions that fall off the scale of each plot. ARFI = acoustic radiation force impulse.
