目的分析乳腺癌的X线钼靶与MRI影像学表现,评价X线钼靶与MRI对乳腺癌的诊断价值。方法分析58例经手术病理证实的乳腺癌X线钼靶与MRI表现。MRI分别采用自旋回波T1WI、短时反转恢复(STIR)序列及动态增强扫描;X线钼靶采用常规方法摄片。结果MRI诊断正确53例,诊断准确率为91.37%,显示钙化8例,钙化显示率为13.97%;X线钼靶诊断正确42例,诊断准确率为72.41%,显示钙化38例,钙化显示率为65.52%。两者差异均有统计学意义(P<0.01)。结论动态增强MRI对乳腺癌的诊断价值明显优于X线钼靶,钼靶对钙化显示较好,两者联合对乳腺癌的临床诊断具有重要意义。
Objective To analyze the mammography and MRI features of breast cancer and evaluate the diagnostic value of mammography and MRI for breast cancer. Methods Fifty-eight cases of breast cancer with X-ray mammography and MRI confirmed by surgery and pathology were analyzed. MRI using spin echo T1WI, short-term reversal recovery (STIR) sequence and dynamic contrast-enhanced scanning; X-ray mammography using conventional methods of radiography. Results Fifty-three cases were correctly diagnosed by MRI, and the diagnostic accuracy rate was 91.37%. Eight cases showed calcification and the rate of calcification was 13.97%. Forty-two cases were correctly diagnosed by X-ray, the diagnostic accuracy was 72.41%. 38 cases showed calcification, Is 65.52%. The differences were statistically significant (P <0.01). Conclusions Dynamic contrast-enhanced MRI is significantly superior to X-ray mammography in the diagnosis of breast cancer. The mammography shows good calcification, which is of great significance in the clinical diagnosis of breast cancer.
