摘　　要：目的探究3.0T磁共振检测前列腺癌中多参数成像(magnetic resonance imaging+diffusion weighted imaging+dynamic contrast-enhanced,MRI+DWI+DCE)与动态增强磁共振成像(dynamic contrast enhanced-magnetic resonance imaging,DCE-MRI)方式的诊断价值。方法选取2022年1月—2023年10月菏泽市中医医院收治的86例疑似前列腺癌患者,以手术切片或穿刺活检的病理诊断结果为金标准,对比MRI+DWI+DCE与DCE-MRI对前列腺癌的诊断结果及诊断效能。结果86例疑似患者确诊前列腺癌25例,前列腺增生61例。DCE-MRI与MRI+DWI+DCE多参数成像的一致性检验kappa值为0.646与0.887。MRI+DWI+DCE多参数成像对前列腺癌诊断的灵敏度、特异度、准确度均高于DCE-MRI,差异均有统计学意义(P均<0.05)。结论3.0T磁共振检测前列腺癌中多参数成像方式相比单一动态增强成像对前列腺癌的诊断准确率更高,误诊与漏诊风险更低,与病理诊断结果具有高度一致性。Objective To investigate the diagnostic accuracy of multi parameter imaging(magnetic resonance imaging+diffusion weighted imaging+dynamic contrast-enhanced,MRI+DWI+DCE)and dynamic contrast enhanced-magnetic resonance imaging(DCE-MRI)in 3.0T magnetic resonance imaging for detecting prostate cancer.Methods A total of 86 patients with suspected prostate cancer admitted to Heze Hospital of Traditional Chinese Medicine from January 2022 to October 2023 were selected.The pathological diagnosis results of surgical section or puncture biopsy were taken as the gold standard,and the diagnostic results and diagnostic efficacy of MRI+DWI+DCE and DCE-MRI for prostate cancer were compared.Results Among suspected 86 patients,25 were diagnosed with prostate cancer and 61 with prostate hyperplasia.The kappa values for consistency testing between DCE-MRI and MRI+DWI+DCE multiparametric imaging were 0.646 and 0.887,respectively.The sensitivity,specificity,and diagnostic accuracy of MRI+DWI+DCE multi parameter imaging in the diagnosis of prostate cancer were significantly higher than DCE-MRI,the differences were statistically significant(all P<0.05).Conclusion In the detection of prostate cancer using 3.0T magnetic resonance imaging,the multi parameter imaging method has a higher diagnostic accuracy and lower risk of misdiagnosis and missed diagnosis compared to a single dynamic enhanced imaging method.It is highly consistent with pathological diagnostic results.
