Multi-centre registry trial tests use of PSMA tracer for early detection of prostate cancer

Led by researchers at Lawson Health Research Institute, a multi-centre registry trial is testing the use of a new imaging tracer, called a PSMA tracer, for early detection of recurrent prostate cancer. The registry gives patients access to a new type of imaging and will assess the impact on patient care.
