Significance of ultrasonography combined with shear wave elastography in the diagnosis of prostate cancer

Abstract

In order to explore the diagnostic value of ultrasound combined with shear wave elastography (SWE) for prostate cancer (PCa), 120 patients with suspected prostate cancer were selected for SWE, contrast-enhanced ultrasound (CEUS), SWE and CEUS combined examination. The results showed that among the 120 patients, 57 cases were diagnosed as prostate cancer and 63 cases as benign prostatic lesions by biopsy. Among 58 cases of PCa diagnosed by SWE, 46 cases were confirmed by pathology, with a sensitivity of 80.70% and a specificity of 77.20%. Among 54 cases of PCa diagnosed by CEUS, 41 cases were confirmed by pathology, with a sensitivity of 80.70% and a specificity of 77.20%. 61 patients with PCa were diagnosed by we and CEUS, and 51 patients were diagnosed by pathology. The sensitivity, specificity and accuracy were 89.47%, 84.70% and 85.38%, respectively. Receiver operating characteristic (ROC) curve results showed that the area under the curve (AUC) of swe and CEUS was 0.944, showing the highest diagnostic efficacy. It can be seen that the combined use of SWE and CEUS provides a more superior diagnostic effect for PCa.
