MSCT双期增强扫描对乳腺癌及早期淋巴结转移的诊断价值

Value of MSCT Dual-phase Enhanced Scan in the Diagnosis of Breast Cancer and Early Lymph Node Metastasis

目的探讨MSCT双期增强扫描对乳腺癌及早期淋巴结转移的诊断价值。方法回顾性分析90例无乳腺症状或体征,并拟手术治疗的乳腺癌患者的临床资料。患者均行常规横轴位胸部MSCT双期增强扫描。术中腋窝淋巴结清扫及术后病理诊断结果作为金标准,记录乳腺癌腋窝淋巴结的CT表现。结果 90例中45例患者乳腺扫描结果异常:26例为原发性乳腺癌,10例为转移性乳腺癌,9例为粘液腺癌。原发性乳腺癌的螺旋CT检出率为28.98%。45例乳腺癌患者共观察腋窝淋巴结80枚,其中转移性淋巴结36枚,非转移性淋巴结44枚。乳腺癌患者年龄在50岁以上。CT扫描肿瘤边缘特征与乳房X线检查和超声检查结果相一致。结论 MSCT双期增强扫描能够检测无症状乳腺癌,对乳腺癌患者腋窝淋巴结转移评估有重要价值。

Objective To investigate the diagnostic value of MSCT dual-phase enhanced scan in breast cancer and early lymph node metastasis. Methods A retrospective analysis of clinical data of 90 cases of breast cancer patients without breast symptoms or signs who intended to receive surgical treatment were conducted. Patients received conventional horizontal position scanning chest MSCT dual-phase enhanced scan,plain chest MSCT dual-phase enhanced scan. With axillary lymph node dissection surgery and postoperative pathological diagnosis as the gold standard,breast cancer axillary lymph nest CT findings were recorded. Results 90 cases of patients,45 cases had abnormal scan results. 26 cases were primary breast cancer,10 cases were metastatic breast cancer,9 cases were benign tumors. Detection rate of primary breast cancer by spiral CT was 28. 98%. 45 cases were breast cancer had 80 axillary lymph nodes,wherein 36 were metastatic lymph nodes,44 were non-metastatic lymph nodes. All breast cancer patients aged 50 years and above. CT scan of the tumor margin characteristics was consistent with the breast X-rays and ultrasound results. Conclusion MSCT dual-phase enhanced scan can detect asymptomatic breast cancer,and it has significant value in evaluation of breast cancer patients with axillary lymph node metastasis.
