OBJECTIVE
Eighteen healthy persons underwent unenhanced MR angiography with a breath-hold ECG-synchronized 3D half-Fourier fast spin-echo technique to evaluate the visibility of the portal vein and its branches.
CONCLUSION
Our results indicated that unenhanced MR angiography with a singlebreath-hold ECG-synchronized 3D half-Fourier fast spin-echo sequence facilitates precise visualization of the anatomic features of the portal vein and its branches without the use of contrast agents.
目的
18名健康受试者采用屏气心电图同步三维半傅里叶快速自旋回波技术进行非增强磁共振血管造影，以评估门静脉及其分支的可视性。
结论
我们的结果表明，采用单次屏气心电图同步三维半傅里叶快速自旋回波序列的非增强磁共振血管造影，无需使用造影剂即可清晰显示门静脉及其分支的解剖特征。
