MRI-Targeted Biopsy in Prostate Cancer Screening

Abstract
To the Editor: In the STHLM3-MRI trial, Eklund et al. (July 9 issue)1 report that the percentage of men in whom clinically insignificant cancer was detected was lower with the use of magnetic resonance imaging (MRI)–targeted biopsy than with standard systematic biopsy, whereas the percentage of those who received a diagnosis of clinically significant cancer was higher with MRI-targeted biopsy.
