Purpose To evaluate the incremental effect of perfusion imaging on biopsy target identification at endorectal multiparametric prostate magnetic resonance imaging (MRI). Materials and methods We retrospectively 52 patients who underwent endorectal multiparametric prostate MRI for suspected or untreated prostate cancer. Two readers independently identified biopsy targets without and with perfusion images. Results Reader 1 identified 36 targets without and 39 targets with perfusion imaging ( P >.05). The corresponding numbers for reader 2 were 38 and 38, respectively ( P =.5). Conclusion Perfusion imaging does not significantly increase the number of biopsy targets identified at endorectal multiparametric prostate MRI.
