摘　　要：目的:统计分析西门子Skyra 3.0T磁共振在老年前列腺癌中的应用诊断价值及准确性。方法:选取2021年1月~2023年12月时段为基础开展数据统计,以该时段首诊80例疑似老年前列腺癌患者为研究对象,均开展西门子Skyra 3.0T磁共振检查与病理检查,对两种技术诊断结果、效能指标、影像学参数与特征加以比较分析。结果:3.0T MRI技术与病理检查的前列腺癌诊断结果对比,差异无统计学意义(P>0.05);3.0T MRI技术诊断前列腺癌的准确性为96.25%,灵敏度为96.49%,特异度为95.65%,阳性预测值为98.21%,阴性预测值为91.67%;依据3.0T MRI技术检查结果,前列腺癌病例的速率常数、容积运转常数高于前列腺良性病变者,容积分数低于前列腺良性病变者,组间数据差异对比有显著性意义(P<0.05);3.0T MRI用于前列腺癌诊断的影像学特征包括血流灌注增强、血管密度增加、毛细血管渗透性增强、血流量增加、低信号特征、边缘模糊不清、单发或多发结节状低信号区等。结论:老年前列腺癌筛查诊断中,应用西门子Skyra 3.0T磁共振技术,能够保证较为准确、可靠的疾病诊断结果。Objective:To statistically analyze the diagnostic value and accuracy of Siemens Skyra 3.0T magnetic resonance imaging in elderly prostate cancer.Methods:The study selected the period from January 2021 to December 2023 as the basis for data statistics.During this period,80 suspected elderly prostate cancer patients were admitted as the research subjects,all of whom underwent Siemens Skyra 3.0T magnetic resonance imaging and pathological examination.The diagnostic results,efficacy indicators,imaging parameters and characteristics of the two technologies were compared and analyzed.Results:There was no statistically significant difference in the diagnostic results of prostate cancer between 3.0T MRI technology and pathological examination(P>0.05);The accuracy of 3.0T MRI technology in diagnosing prostate cancer was 96.25%,sensitivity was 96.49%,specificity was 95.65%,positive predictive value was 98.21%,and negative predictive value was 91.67%;According to the results of 3.0T MRI technology examination,the Kep and Ktrans of prostate cancer cases were higher than those of benign prostatic lesions,and Ve was lower than those of benign prostatic lesions.The difference in data between groups was compared(P<0.05);The imaging features of 3.0T MRI used for the diagnosis of prostate cancer include enhanced blood flow perfusion,increased vascular density,enhanced capillary permeability,increased blood flow,low signal features,blurred edges,single or multiple nodular low signal areas,etc.Conclusion:In the screening and diagnosis of elderly prostate cancer,the application of Siemens Skyra 3.0T magnetic resonance technology can ensure more accurate and reliable disease diagnosis results.
