Comparison of Clinical Value of Transrectal Ultrasound, Contrast-enhanced Ultrasonography and Dynamic Contrast Material-enhanced Magnetic Resonance Imaging for Detecting Prostate Carcinoma

Objective To compare the clinical value of transrectal ultrasound(TRUS), contrast-enhanced ultrasonography(CEUS) and dynamic contrast material-enhanced magnetic resonance imaging(DCE-MRI) for detecting prostate carcinoma. Methods Sixty-three patients were suspected clinically of prostate carcinoma and underwent systematic biopsy further. We retrospectively analyzed the relative test data of TRUS, CEUS and DCE-MRI before operation. The pathological results of biopsy were performed to evaluate the diagnostic value of TRUS, CEUS and DCE-MRI. Results In diagnosing prostate carcinoma, the sensitivity, specificity and accurate rates were 48.84%, 60% and 52.38% with TRUS, 74.42%, 65% and 71.43% with CEUS and 69.77%, 85% and 74.60% with DCE-MRI, retrospectively(P>0.05). Area under ROC curves of TRUS, CEUS, DCE-MRI were 0.550, 0.723, 0.781, and DCE-MRI had the highest sensitivity and accuracy. Conclusion The screening for patients suspected of prostate carcinoma, CEUS and DCE-MRI have higher accuracy than TRUS. The sensitivity and accuracy of DCE-MRI are the highest.
