3.0T核磁共振成像LAVA动态增强在乳腺良恶性病变的诊断价值

Enhancing the value of dynamic analysis and diagnosis of benign and malignant breast lesions 3.0T MRI LAVA

目的研究3.0T核磁共振成像LAVA动态增强对乳腺恶性肿瘤的鉴别价值,为治疗提供依据。方法选择2013-02—2016-03间收治的36例乳腺良恶性病变患者为观察对象。采用SIMENS 3.0T超导MRI对患者进行平扫及LAVA动态增强扫描,与术后病理穿刺检测结果进行比较。计算动态增强的灵敏度、特异度、准确度。结果乳腺癌患者LAVA动态增强曲线呈早期信号快速上升,中晚期信号强度逐渐降低表现。患者动态增强曲线呈逐渐上升改变。3.0TMRI平扫显示乳腺良恶性病变信号无统计学意义,LAVA显示良恶性肿瘤形态差异明显。良性肿瘤表现为Ⅰ型曲线,诊断的特异度较高(97.3%),恶性肿瘤表现为Ⅲ型曲线,诊断准确度较高(83.2%)。结论 3.0T核磁共振成像LAVA动态增强序列,可以清晰显示乳腺良恶性病变的形态、边缘,具有较高诊断价值。

Objective To study the dynamic contrast-enhanced 3. 0T MRI LAVA differential value of breast cancer and provide the basis for clinical treatment. Methods From Our hospital February 2013-March 2016 patients with breast benign and malignant lesions admitted to the observed object 36 cases,using SIMENS 3. 0T superconducting MRI scan and the patient LAVA dynamic contrast-enhanced scan sequence and the results with surgery or pathology biopsy test results were compared to calculate the dynamic enhanced sensitivity,specificity and accuracy. Results LAVA dynamic enhancement curves in breast cancer patients showed early signs of a rapid increase in signal intensity decreases with advanced performance; breast cancer patients showed a gradual increase in dynamic enhancement curve change. 3. 0TMRI scan shows benign and malignant breast lesions signal no statistically significant; LAVA dynamic contrast-enhanced sequence shows significant differences between benign and malignant forms. Ⅰ benign performance curve,the higher diagnostic specificity of 97. 3%,malignant tumors showed Ⅲ type curve,the diagnostic accuracy was 83. 2% higher. Conclusion LAVA dynamic contrast-enhanced MRI 3. 0T sequence can clearly show the morphology of benign and malignant breast lesions,the edge has a high diagnostic value.
