乳腺能谱成像对乳腺疾病的诊断价值

The Value of Mammography in the Diagnosis of Breast Diseases

目的:探讨对比增强能谱乳腺X线摄影(CESM)诊断乳腺病变的价值.方法:回顾性纳入经临床检查或超声怀疑有乳腺异常病变,完成乳腺CESM检查,并且最终经病理证实的100例患者.对病理标本进行判读,获得病理分类诊断结果,并根据病理查找转移淋巴结.以病理结果为金标准,分析此种影像方法和病理诊断的一致性.结果:100例患者共检出100个病灶,淋巴结126枚;CESM诊断乳腺恶性病变68例,诊断乳腺恶性病变的转移淋巴结73枚,病理诊断乳腺恶性病例64例,转移淋巴结56枚,CESM与病理结果为金标准对比,符合率分别为94%和76%.结论:CESM显示和诊断乳腺疾病更有价值,值得临床开展,对比增强数字钼靶增强了传统数字钼靶的表现,也为乳腺癌分期提供了一种新的信息手段.

Objective： To evaluate the diagnostic value of contrast enhanced energy spectrum mammography （CESM） in breast lesions. Methods： 100 patients who were suspected to have abnormal breast lesions by clinical ex- amination or ultrasonography, underwent breast CESM examination, and finally confirmed by pathology were included retrospectively. The pathological specimens were identified to obtain the pathological classification diagnosis results, and metastatic lymph nodes were searched according to pathology. Taking pathological results as the gold standard, the consistency of this imaging method and pathological diagnosis was analyzed. Results： 100 lesions and 126 lymph nodes were detected in 100 patients. 68 cases of malignant breast lesions and 73 cases of metastatic lymph nodes of malignant breast lesions were diagnosed by CESM. 64 malignant breast lesions and 56 metastatic lymph nodes were diagnosed by pathological diagnosis. Comparing CESM with the gold standard of pathological results, the coincidence rate was 94% and 76% respectively. Conclusion： CESM is more valuable in displaying and diagnosing of breast diseases, and worthy of clinical development. Contrast enhanced digital molybdenum target enhances the performance of traditional digital molybdenum target, and provides a new information means for breast cancer staging.
