Abstract
Our aim was to improve the detection of prostate cancer by evaluating whether contrast-enhanced ultrasound (CEUS) or sonoelastography (SE) is more helpful in guiding targeted biopsy (TB) performed before systematic biopsy (SB). A total of 52 patients suspected of having prostate cancer were prospectively included and randomly assigned to either the CEUS or SE group. Different, independent radiologists performed TB and twelve-core SB. Within each group, cancer detection rates based on core number were compared between SB and TB. We evaluated the effect of TB on core-based cancer detection rates between the CEUS and SE groups. Cancer detection was higher in overall TB cores 16.4% (28/171) than SB cores 11.4% (71/624) in both groups. In the SE group, TB cores revealed higher cancer detection than did SB cores from 4.49% (14/312) to 12.86% (9/70) (p = 0.01). Compared with CEUS, SE may improve detection rates when considering additional TB guidance methods.
