Abstract:
【Objective】 To explore the application value of transrectal contrast-enhanced ultrasound (CEUS) microangiography, elastography and conventional ultrasound-guided prostate cancer puncture biopsy in the diagnosis of prostate diseases, so as to provide reference for the early diagnosis of prostate cancer. 【Methods】 A total of 156 patients suspected of prostate cancer treated in our hospital during Jan.2021 and Dec.2022 were selected.The patients were divided into group A (n=52, conventional ultrasound), group B (n=49, elastography) and group C (n=55, CEUS microangiography) according to the puncture methods.The positive rate of puncture and diagnostic value of the three methods were analyzed. 【Results】 The positive rate of puncture was 24.18% in group B and 25.71% in group C, which was significantly higher than that in group A (13.15%, P<0.05).The diagnostic accuracy of prostate cancer was 93.88% in group B and 94.55% in group C, higher than that in group A (75.00%, P=0.002).In group B, the Emax and Emean of malignant lesions were (65.56±14.43) kPa and (59.59±11.02) kPa, respectively, which were higher than those of benign lesions (P<0.001).The difference in blood flow grade detected by CEUS microangiography was statistically significant between benign and malignant lesions, and grade 3 blood flow accounted for 95.65% of malignant lesions.The area under the receiver operating characteristic (ROC) curve (AUC) of Emean in elastography in the diagnosis of prostate cancer was 0.810 (95%CI: 0.690-0.930, P<0.05).The AUC of CEUS microangiography in the diagnosis of prostate cancer was 0.965 (95%CI: 0.913-1.000, P<0.05). 【Conclusion】 Compared with conventional ultrasound-guided prostate cancer puncture biopsy, CEUS microangiography and elastography guided prostate cancer puncture biopsy have better application value in the diagnosis of prostate diseases, which can provide semi-quantitative/quantitative parameter basis for the diagnosis of prostate diseases.
