摘　　要：目的探讨3D Bravo、3D Cube Flair两种MR增强扫描序列用于肺癌脑转移病灶的检验能力。方法选择我院肿瘤科2016年1月至2020年1月期间收治100例肺癌脑转移病灶患者为研究对象,全部观察对象均分别接受本研究方案的MR增强扫描,对比两组检查技术的检出情况、判读结果和信号强度。结果3D Bravo MR增强扫描对于脑膜转移和脑内转移的临床检出率均明显高于3D Cube Flair MR增强扫描,两种方法病灶部位检出数据对比差异具有统计学意义(P<0.05),3D Bravo序列检出率为93.2%,漏诊率6.8%,误诊率为0.4%,3D Cube Flair序列检出率96.8%,漏诊率3.2%,误诊率为1.4%,数据分析结果比较差异具有统计学意义(P<0.05),两种序列的图像质量都比较理想,但部分患者可见伪影情况,3D Bravo和3D Cube Flair序列图像测量的信号强度CR符合正态性分布特征,但两者病灶与正常灰质、病灶与正常白质的信号强度对比差异具有统计学意义(P<0.05)。结论3D Cube Flair序列MR增强扫描用于肺癌脑转移病灶的检查和诊断,应用效果较好,但3D Bravo与3D Cube Flair序列联合应用能够提高检查的可靠性。Objective To evaluate the ability of 3D Bravo and 3D cube flair enhanced MR sequences in detecting brain metastases from lung cancer.Methods from January 2016 to January 2020,100 patients with brain metastases from lung cancer in our hospital were selected as the research objects.All the observation objects received the enhanced MR scanning of this research scheme.The detection,interpretation results and signal intensity of the two groups were compared.Results the clinical detection rate of meningeal metastasis and intracerebral metastasis in 3D Bravo enhanced MR scan was significantly higher than that in 3D cube flair enhanced MR scan,and the difference was statistically significant(P<0.05).The detection rate of 3D Bravo sequence was 93.2%,the missed diagnosis rate was 6.8%,the misdiagnosis rate was 0.4%,the detection rate of 3D cube FLAIR sequence was 96.8%,the missed diagnosis rate was 3.2%,and the misdiagnosis rate was 1.4%,The difference of data analysis results was statistically significant(P<0.05).The image quality of the two sequences was ideal,but artifacts could be seen in some patients.The signal intensity CR measured by 3D Bravo and 3D cube flair sequences was consistent with the normal distribution characteristics,but the lesions of the two sequences were similar to those of normal gray matter and gray matter There was significant difference in signal intensity between lesions and normal white matter(P<0.05).Conclusion 3D cube FLAIR sequence enhanced MR scanning has a good effect in the detection and diagnosis of brain metastases of lung cancer,but 3D Bravo combined with 3D cube FLAIR sequence can improve the reliability of the examination.
