Prostagram, developed by experts at Imperial College London, employs MRI scanning and is modelled on breast cancer screening, where women are routinely offered a mammogram scan every three years as part of a national programme. A trial of 408 men, the results of which were published in Jama Oncology on Thursday, found that Prostagram detected approximately twice as many clinically significant cancers as the standard PSA (prostate specific antigen) blood test.
