摘要
目的探讨乳腺癌的乳腺X线和MRI影像学表现及其诊断价值。方法选择2017年3月~2018年10月疑似乳腺癌患者50例为研究对象,其均接受乳腺X线、MRI影像学检查以及病理检查,以病理检查结果作为金标准,对疑似乳腺癌患者的乳腺X线、MRI检验结果进行分析。结果经手术后病理检查确诊为恶性肿块者35例,良性肿块15例;乳腺X线检查,检出良性包块25例,检出恶性包块25例,其恶性包块的X线表现主要为团块阴影、结节影、乳腺皮肤增厚、细砂样或针尖样钙化、边缘分叶状、毛刺征、腋下淋巴结肿大、乳头凹陷;良性包块的X线表现主要为粗大棒状钙化影、局部密度增高影、类圆形结节影(边缘光滑);MRI检查,检出良性包块18例,检出恶性包块32例,其恶性包块的MRI表现为结节及团块影、腋窝淋巴结肿大、乳腺皮肤水肿、毛刺征;良性包块的MRI表现为包块边缘较为光滑,且其周围分界清晰,为块状影或结节影;病理、MRI对乳腺癌的确诊率均明显高于乳腺X线的确诊率,差异有统计学意义(P<0.05);病理对乳腺癌的确诊率与MRI检出率相比,差异无统计学意义(P>0.05)。结论乳腺X线、MRI在乳腺癌诊断中应用,均具有一定的价值临床应根据患者的具体情况合理选择影像学检查方法。
Objective To investigate the mammography and MRI imaging findings of breast cancer and their diagnostic value.Methods A total of 50 patients with suspected breast cancer from March 2017 to October 2018 were enrolled in the study.All of them underwent mammography,MRI imaging and pathological examination.The results of pathological examination were used as the gold standard,and the mammography and MRI results of patients with suspected breast cancer were analyzed.Results 35 cases of malignant masses and 15 cases of benign masses were diagnosed by pathological examination after operation.In mammography,25 cases of benign mass were detected and 25 cases of malignant mass were detected.The mammography findings of malignant mass were mainly shadow of the mass,nodular shadow,thickening of the breast skin,fine sand or needle-like calcification,marginal lobulation,burr sign,axillary lymph node enlargement and nipple depression.Mammography findings of benign mass were mainly thick rod calcification,local density increase,round nodules(smooth edge).18 cases of benign mass and 32 cases of malignant mass were detected by MRI examination.The MRI findings of malignant mass were nodule and mass block shadow,axillary lymph node enlargement,breast skin edema and burr sign.The MRI findings of benign mass were smooth edge of the mass,and clear surrounding boundary,which was blocky or nodular shadow.The diagnosis rate of pathology,MRI for breast cancer was significantly higher than that of mammography.The difference was statistically significant(P<0.05).There was no significant difference between the diagnosis rate by pathology and the detection rate by MRI in breast cancer(P>0.05).Conclusion The application of mammography and MRI in the diagnosis of breast cancer has certain value.Clinically,the imaging examination method should be reasonably selected according to the specific conditions of the patient.
