Abstract

Abstract: This study explored the application of MRI combined with transrectal ultrasound (TRUS) targeted puncture in the diagnosis of prostate cancer (PCA). 234 patients with prostate disease diagnosed by MRI combined with transrectal ultrasound targeted puncture were selected as the targeted group, including 114 patients with PCA (PCA group) and 120 patients with benign prostatic hyperplasia (benign group), and then the imaging features of the two groups were compared. In addition, 106 patients in the same period with prostate disease who received traditional 12-needle transrectal ultrasound puncture were selected as the control group. Compared the number of puncture needles and the length of cancer tissue obtained by the two puncture methods. The results showed that in MRI features, the proportion of patients with low T2WI signal, irregular lesion morphology, blurred lesion boundary and diffusion-weighted imaging with high signal in PCA group was significantly higher than that in benign group (P<0.05). Comparison of ultrasound imaging features, the proportion of patients with hypoecho, irregular shape of lesions, microcalcified lesions, posterior echo attenuation, and blood flow grade (2-3) in PCA group was significantly higher than that in benign group (P<0.05). The average number of puncture needles in the targeted group was significantly lower than that in the control group (P<0.05). The length of cancer tissue obtained by puncture in the targeted group was longer than that in the control group (P<0.05). MRI combined with transrectal ultrasound targeted puncture has higher clinical value in the diagnosis of prostate cancer.
