Diagnostic Accuracy and Predictive Values of Systematic 12-Core Biopsy and Targeted Magnetic Resonance Imaging/Transrectal Ultrasonography Fusion Biopsy for Detection of Tumors Greater Than 500 mm³

Biopsy method	Sens (%)	Spec (%)	Accuracy (%)	PPV (%)	NPV (%)
Systematic 12-core biopsy	25	90.9	54	77.8	48.8
Targeted MRI/TRUS fusion biopsy	53.6	86.4	68	83.3	59.4

Sens=sensitivity; Spec=specificity; PPV=positive predictive value; NPV=negative predictive value; MRI/TRUS=magnetic resonance imaging/transrectal ultrasonography.
