摘　　要：目的探究乳腺钼靶X线摄影和磁共振成像(MRI)在乳腺癌诊断中的临床应用价值。方法选取2017年6月至2019年10月本院收治的经手术病理确诊为乳腺癌的患者64例,所有患者术前均行钼靶X线检查和MRI检查,比较两种检查方法的病灶检出率、恶性肿瘤确诊率、钙化病灶检出率和病灶大小符合率。结果MRI的病灶检出率为91.55%,高于钼靶X线(71.83%,P<0.05);MRI的浸润导管癌(IDC)检出率高于钼靶X线检查(P<0.05),浸润小叶癌(LDC)和导管内原位癌(DCIS)检出率比较,差异无统计学意义(P>0.05);MRI检查的恶性肿瘤确诊率高于钼靶X线检查,钙化病灶检出率低于钼靶X线检查(P<0.05);钼靶X线、MRI与病理检查肿瘤最大直径测量值呈正相关,且MRI与病理检查符合度高于钼靶X线(rMRI>r钼靶X线)。结论MRI对乳腺癌诊断的准确率和病灶大小符合率高于钼靶X线检查,但钼靶X线对呈钙化表现的乳腺癌的诊断具有重要意义,临床可通过乳腺钼靶X线摄影联合MRI检查提高对乳腺癌诊断的准确率。Objective To explore the clinical value of mammography and magnetic resonance imaging(MRI)in the diagnosising breast cancer.Methods 64 patients with breast cancer confirmed by surgical pathology between June 2017 and October 2019 were selected.All patients completed mammography and MRI examinations before surgery.The detection rates of lesions,diagnosis rates of malignant tumors,detection rates of calcified lesions,and the coincidence rates of lesion size were compared between the two methods.Results The lesion detection rate of MRI(91.55%)was higher than that of mammography(71.83%)(P<0.05),and the detection rate of invasive ductal carcinoma(IDC)by MRI was higher than that by mammography(P<0.05).There was no statistically significant difference in the detection rate of invasive lobular carcinoma(ILC)or ductal carcinoma in situ(DCIS)(P>0.05).The diagnosis rate of malignant tumors by MRI was higher than that by mammography,and the detection calcified lesions was lower than mammography(P<0.05).The maximum tumor diameters measured by mammography and MRI were positively correlated with that measured by pathological examination,and the conformity of MRI with pathological examination was higher than mammography(r MRI>r mammography).Conclusion The accuracy of MRI in diagnosising breast cancer and the coincidence rate of lesion size are higher than those of mammography,but mammography is of great significance in diagnosising breast cancer with calcification.Clinically,mammography can be combined with MRI examination to improve the diagnostic accuracy of breast cancer.
