“The use of multi-parametric magnetic resonance imaging (mpMRI) could help avoid a repeat prostate biopsy in some men, according to a new study. The imaging test has a high sensitivity for clinically significant cancers, but could miss some and overdiagnose insignificant cancers as well.
” ‘The prostate cancer diagnostic pathway is very different to that of almost all other solid organ cancers, in that it is calibrated to detect subclinical disease but often misses clinically important disease,’ wrote study authors led by Lucy A. M. Simmons, MBBS, MRCS, of University College London. That imprecision arises from the use of transrectal ultrasound-guided (TRUS) biopsy, which is considered standard in men with elevated prostate-specific antigen (PSA) levels.”
