Evolução interessante uma vez que a biópsia tinha efeitos secundarios possíveis como disfunção eréctil e uma taxa de detecção correcta (de tumores agressivos que requerem atenção imediata) muito baixa:

"The biggest leap in diagnosing prostate cancer "in decades" has been made using new scanning equipment, say doctors and campaigners.
Using advanced MRI nearly doubles the number of aggressive tumours that are caught.
And the trial on 576 men, published in the Lancet, showed more than a quarter could be spared invasive biopsies, which can lead to severe side-effects.
The NHS is already reviewing whether the scans can be introduced widely.
Prostate cancer is the most common cancer in British men (...)"
"If men have high prostate specific antigen (PSA) levels in the blood, they go for a biopsy.
Twelve needles then take random samples from the whole of the prostate.
It can miss a cancer that is there, fail to spot whether it is aggressive, and cause side-effects including bleeding, serious infections and erectile dysfunction.
"Taking a random biopsy from the breast would not be accepted, but we accept that in prostate," said Dr Hashim Ahmed, a consultant and one of the researchers.
Around 100,000 to 120,000 men go through this every year in the UK."

"93% of aggressive cancers were detected by using the MRI scan to guide the biopsy compared with just 48% when the biopsy was done at random."
