X线、MRI对乳腺癌的综合诊断价值

Clinical application value of X -ray and MRI in the diagnosis of breast carcinoma

目的:探讨X线、MRI对乳腺癌的综合诊断价值。方法:分析经手术病理证实的30例乳腺癌患者X线、MRI的影像表现,分别从病灶形态学、钙化、淋巴结、皮肤及胸壁受累情况及信号特点、强化模式等方面进行分析和诊断,比较两种方法在检出率、诊断准确率、病灶范围的确定等方面的价值。结果:X线检出病灶26个,检出率为87.3%,诊断准确率为83.3%;MRI检出病灶32个,检出率为100.0%,诊断准确率为92.7%。结论:乳腺X线摄影检查直观、有效,是诊断乳腺癌的首选检查方法,结合MRI可提高诊断的灵敏度和特异度。

Objective： To investigate the comprehensive value of X-ray mammography and MRI in diagnosing the breast cancer. Methods： 30 cases of patients with breast cancer were enrolled, both mammography and MRI scan were performed, including tumor morphology, calcification, signal characteristics, enhanced mode and Si-time curve. The values of X-ray and MRI were evaluated. Results： 26 masses were found by X-ray mammogram, detection rate was 87.3% and accuracy rate of X-ray was 83.3%; 32 masses were detected by MRI, detection rate was 100.0% and accuracy rate of MRI was 92.7%. Conclusion： A direct and effective means to breast cancer should be based on X-ray. The molybdenum X-ray mammography is helpful in the diagnosis of breast cancer, the sensitivity and specificity combined with MRI are enhanced when compared to that of single modality
