摘　　要：目的观察磁共振成像(MRI)联合经直肠超声(TRUS)诊断前列腺癌(PCa)的价值及影像特点。方法选取2017年8月至2019年8月本院收治的80例疑似PCa患者为研究对象,均经MRI和TRUS检查,与病理结果进行对照。结果术后组织病理结果显示,80例疑似PCa患者中良性48例,恶性32例,与组织病理学结果对照,MRI诊断PCa的准确性为75.00%,TRUS诊断PCa的准确性为72.50%,MRI联合TRUS诊断PCa的准确性为91.25%。MRI联合TRUS诊断PCa的灵敏度均高于单独检测(P<0.05)。结论MRI、TRUS诊断PCa各有优势和局限性,两者联合可提高PCa的检出率。Objective To observe the value and imaging characteristics of magnetic resonance imaging(MRI)combined with transrectal ultrasound(TRUS)in the diagnosis of prostate cancer(PCa).Methods 80 patients with suspected PCA admitted to our hospital from August 2017 to August 2019 were selected as the study objects;all of them were examined by MRI and TRUS,and compared with the pathological results.Results the results of postoperative histopathology showed that 48 cases were benign and 32 cases were malignant.Compared with the histopathological results,the accuracy of MRI in diagnosing PCA was 75.00%,TRUS in 72.50%,and TRUS in 91.25%.The sensitivity of MRI combined with TRUS in the diagnosis of PCA was higher than that of single detection(P<0.05).Conclusion MRI and TRUS have their own advantages and limitations in the diagnosis of PCA.The combination of them can improve the detection rate of PCa.
