Prostate Volume Calculator

Ultrasound and MRI reports give the prostate as three measurements, and the volume is worked out from them with the ellipsoid formula: length times width times height times 0.52. Enter the three dimensions in centimetres or millimetres and the tool returns the volume in cc, the slightly larger figure a report using pi/6 exactly would print, and an approximate weight. Add a serum PSA value and it also divides one by the other to give the PSA density. This reports a measurement, not a diagnosis, and the ellipsoid formula is an approximation that repeat scans of the same gland disagree with by ten percent or so.
