Conclusion
Previous Reports
- No report on T-SLIP hepatic MR arteriography in 3T
- 1 paper on T-SLIP hepatic MR arteriography in 1.5T (normal volunteers,
Shimada K,
et al.
Eur J Radiol 2011)
- 1 paper on unenhanced hepatic MRA using other technique (1.5T,
axial plane-based,
Puippe GD,
et al.
Eur J Radiol 2012)
Remaining Problems
- Poor visualization of peripheral small branches
- Poor visualization due to irregular respiration or visualization of vein or bile duct
- Overdiagnosis of stenosis
- Banding artifacts due to imaging sequence used (SSFP)
- Unknown effects of previous treatments
- Unknown effects of cardiac function or aortic diseases
- No comparison between 1.5T and 3T
- No systematic comparison between CE-CTA and T-SLIP-MRA
Conclusion
Our results suggested that anatomy of hepatic artery can be assessed and classified using T-SLIP hepatic MR arteriography at 3T-MRI.
