Prostate Cancer Gene 3 (PCA3) Test
The PCA3 assay is a genetic diagnostic test and can be used in conjunction with traditional tests to diagnose prostate cancer. PCA3 is highly prostate cancer specific. It uses urine to measure the PCA3 and PSA messenger RNA; these are then used to calculate the PCA3 score. The PCA3 score is not affected by the prostate volume. It is, however, not a definitive test and should be reviewed in conjunction with other investigations.
Gadolinium Enhanced MRI (Magnetic Resonance Imaging)
MRI is a medical imaging technique used to visualise the internal structure and function of the body. A gadolinium enhanced MRI is used to scan the prostate and pelvic area using a special contrast agent which can show up abnormal areas within the prostate. If the MRI is read by an experienced uro-radiologist, it can give valuable information regarding the diagnosis of prostate disease.
