- PSA density | Radiology Reference Article | Radiopaedia. org
The PSA density (PSAD) is calculated at diagnosis of prostate cancer and is the serum prostate-specific antigen (PSA) level (ng mL) divided by the prostate gland's volume (mL), resulting in a value in the units ng mL2 1 Prostate volume is calcul

The PSA velocity (PSAV) is a statistically derived measure of how prostate specific antigen (PSA) levels change over time and has been used as a marker of how prostate cancer progresses or regresses Calculation Calculating PSA velocity, or si

- Prostate specific antigen - Radiopaedia. org
Prostate specific antigen (PSA) is used as a tumour marker for prostate cancer PSA is a 33-kilodalton glycoprotein produced in prostate epithelial cells Its normal physiologic role is as a liquefying agent for seminal fluid; only a tiny amount leaks into the blood, so its normal serum level is usually very low Prostate specific antigen can exist in the serum in two forms: bound complexed
