WebbMRI is ideally suited to the quantification of fat, since most of the acquired signal comes from water and fat protons. Fat fraction (FF, the proportion of the acquired signal derived from fat protons) has, therefore, emerged as an objective, image-based biomarker of … WebbProstate volume formula. This calculator uses the ellipsoid formula: H × W × L × 0.523 based on the height (H), width (W), and length (L) of the prostate. The normal prostate measures approximately 3 × 3 × 5 centimeters, and has a volume of about 25 mL. The most commonly used threshold for prostatomegaly is >30 mL.
