| 目的 评价TrueFISP序列及Haste序列对主动脉夹层的诊断价值。方法 收集我院彩超高度怀疑主动脉夹层的病例31例,采用西门子1.5T超导MR成像仪,所有病例均行心电门控TrueFISP序列轴位、冠状位及平行于主动脉弓的斜矢状位以及屏气Haste序列轴位扫描。结果 MRI阳性25例,阴性6例,所有阳性病例均能显示明确的真假腔及内膜片,部分病例显示有附壁血栓,Haste序列假腔部分病例呈稍高信号改变,真腔呈黑血改变,TrueFISP序列真假腔均呈亮血改变;内膜片在TrueFISP序列及Haste序列上均呈线样等信号影;阳性病例Debakey分型:Ⅰ型10例,Ⅱ型5例,Ⅲ型10例。结论 高场MR运用TrueFISP序列及Haste序列对主动脉夹层的诊断有重要价值。 |

| Objective To evaluate the value of TrueFISP and HASTE in diagnosing aortic dissection. Methods A total of 31 patients with clinically suspected. A 1.5T MR system as used. Multiple fast sequences including TrueFISP axial, coronal, oblique and HASTE axial was initially applied. Results Twenty-five patients with aortic dissection were found, 6 patients without aortic dissection. Double lumen and intimae flap could be shown in all of 25 patients. There were 10 Debakey type Ⅰ dissections, 5 Debakey type Ⅱ dissections and 10 Debakey type Ⅲ dissections. Conclusion TrueFISP and HASTE is very helpful for making the diagnosis of aortic dissection. |
