目的 探讨3.0T MRI多序列联合 扫描在评定颅脑损伤严重程度中的应用价 值。方法 收集2014年2月-2016年3月我院 收治的80例颅脑损伤患者的临床资料，所 有患者均完成3.0T MRI多序列检查，比较 不同严重程度颅脑损伤患者MRI影像学特 点，分析各序列对颅脑损伤病灶的检出 价值。结果 ESWAN检出颅脑损伤患者出 血灶数目高于其他各序列，其次为FLAIR 序列，以颞枕顶叶、额叶出血灶数目较 多；轻型组MRI出血灶检出数目低于中型 组与重型组(P<0.05)，中型组出血灶检出 数目低于重型组(P<0.05)；轻型组不同 部位出血灶体积均小于中型组与重型组 (P<0.05)，中型组出血灶体积又小于重型 组(P<0.05)。结论 3.0T MRI多序列联合 扫描可全面性显示颅脑损伤患者颅内病 变情况，其中ESWAN序列对出血灶显示率 高，且随颅脑损伤程度的加重，患者出血 灶增多，体积增加。

Objective To investigate the application value of combined scanning of 3.0T MRI multiple sequences in evaluating the severity of craniocerebral injury. Methods The clinical data of 80 patients with craniocerebral injury admitted to our hospital from February 2014 to March 2016 were collected. All patients were examined with 3.0T MRI multiple sequences. MRI features in patients with different degrees of craniocerebral injury were compared, and the value of each sequence in the detection of craniocerebral injury was analyzed. Results The number of bleeding foci in patients with craniocerebral injury detected by ESWAN was more than other sequences, followed by FLAIR sequence. Lesions in temporal and occipital parietal lobes and frontal lobe were relatively more. The lesions in the mild group detected by MRI were less than that the moderate group and the severe group (P<0.05), and the detected lesions in the moderate group were fewer than the severe group (P<0.05). The volume of hemorrhage in different parts of the mild group was smaller than that in the moderate group and the severe group (P<0.05), and the volume of hemorrhage in the moderate group was smaller than that in the severe group (P<0.05). Conclusion The combined scanning of 3.0T MRI multiple sequences can fully display intracranial lesions in patients with craniocerebral injury, and the display rate of ESWAN is the highest. With the exacerbation of craniocerebral injury, hemorrhage increases and the volume increases.
