Micro-ultrasound and MRI show similar effectiveness for prostate cancer imaging

Key clinical point: Micro-ultrasound showed similar or better sensitivity and similar specificity to multiparametric MRI for imaging prostate cancer.

Major finding: Micro-ultrasound and multiparametric MRI sensitivities for imaging prostate cancer were 94% vs. 90%, respectively, and negative predictive values were 85% vs. 77%, respectively, while specificities of both were 22% and positive predictive values were 44% and 43%, respectively.

Study details: The data come from a multicenter, prospective study of 1,040 adults with prostate cancer at 11 sites in 7 countries who had undergone multiparametric MRI imaging and underwent imaging with micro-ultrasound.

Disclosures: The Terry Fox Foundation provided funding for the Sunnybrook ExactVue imaging system used in the study. The researchers had no financial conflicts to disclose.
