| 目的 探讨磁共振肺灌注成像(MRPP) 联合Gd2DTPA 增强磁共振血管造影(MRA) 诊断急性肺栓塞
(APE) 的可行性及其作用。方法 对10 只犬肺栓塞模型,利用2D 快速扰相梯度回波序列(2D FSPGR) 和3D 快速
扰相梯度回波序列(3D FSPGR) 行MRPP 和增强MRA 检查,以肺X 线血管造影和肺血管解剖为对照,计算MRPP
和MRA 诊断急性肺栓塞的敏感度,探讨其诊断价值。结果 MRPP 和MRA 图像质量良好,MRPP 显示较大面积灌
注不良效果良好,敏感度为6512 % ,MRA 诊断外周肺动脉血栓的准确率较高,敏感度达8216 %。结论 MRPP 联合
MRA 扫描是诊断急性肺栓塞的可行方法,有待于进一步行临床研究。 |

| Objective To probe into the feasibility and value of magnetic resonance pulmonary perfusion (MRPP) combined with Gd-DTPA enhanced magnetic resonance angiography (MRA) in the diagnosis of acute pulmonary embolism
(APE) . Methods Ten dogs with experimental APE were scanned with two-dimensional fast spoiled gradient echo sueence
(2D FSPGR) to obtain MRPP and contrast-enhanced MRA. The images of MRPP and MRA were analyses according to the
findings of X-ray pulmonary angiography and pathological dissection. Results The quality of MRPP and MRA were good.
The sensitivity of MRPP ,and MRA was 65. 2 % and 82. 6 % respectively. Conclusion MRPP combined with contrast2enhanced MRA is a feasible method to diagnose APE ,and the clinical investigation should be done in future. |
