多b值DWI联合MRI动态增强在乳腺癌诊断的效能分析

目的 探讨多b值扩散加权成像(DWI)联合磁共振成像(MRI)动态增强在乳腺癌诊断的效能.方法 现对临床收治的75例疑似乳腺癌患者展开研究,入院时间在2018年5月至2019年12月间,所有患者均先予以多b值DWI和MRI动态增强检查,然后再予以患者手术病理检查,最后以病理检查结果为"金标准",探讨两种检查方式单独检查...

Multi-b-value DWI Combined with MRI Dynamic Enhancement in the Diagnosis of Breast Cancer

Objective To investigate the diagnostic efficacy of DWI combined with MRI in breast cancer.Methods 75 cases of suspected breast cancer were studied.The admission time was from May 2018 to December 2019.The patients were examined with multi-b-value DWI and MRI Dynamic enhancement,followed by su rgical and pathological examination.Finally,the diagnostic effica cy of the two examination methods was discussed based on the pathological examination results.Results The specificity,sensitivity,negative and positive predictive values of DWI were 56.76%,31.59%,44.68%and 42.86%respectively when b value=500 s/mm²,which was statistically significant compared with 89.19%,76.32%,78.57%and 87.88%when b value=800 s/mm²(P<0.05),but not statistically significant compared with 59.46%,39.47%,48.89%and 50%when b value=1000 s/mm²(P>0.05),and there was no significant difference in Multi-b value DWI The specificity,sensitivity,negative and positive predictive values were 89.19%,76.32%,78.57%and 87.88%respectively,while the specificity,sensitivity,negative and positive predictive values of dynamic contrast-enhanced M RI were86.49%,71.05%,74.42%and 84.38%respectively.The difference between the two methods was not statistically significa nt(P>0.05),but the diagnostic efficacy of the two methods was higher than that of the combined examination.The difference of diagnostic efficacy was statistically significant(P<0.05).Conclusion Multi-b-value DWI and MRI dynamic contrast-enhanced scan have certain diagnostic value in the diagnosis of breast cancer.However the combination of them can effectively make up for the deficiencies in detection,improve the clinical diagnosis efficiency,and have more significant value in breast cancer diagnosis.
