Abstract Objective: To evaluate the application values of 3.0T MR NATIVE True-FISP sequence in hepatic portal venography by comparing with the research of contrast-enhanced magnetic resonance angiography(MRA) of the hepatic portal vein. Methods: Magnetic resonance enhancement imaging and NATIVE True-FISP sequence hepatic portal vein imaging were performed in 17 patients with suspected hepatic lesions in our hospital. The scanned images were subjectively scored by two deputy directors MR diagnosticians for the display of the portal vein and its branches, and compared the differences between the two examination methods for the portal vein were. Results: Fourteen patients completed the examination, while the other three did not because of trouble breathing. The NATIVE True-FISP sequence showed that its image quality of portal vein had no significant statistical difference(P>0.05) with dynamic contrast-enhanced MRA. Conclusion: 3.0T MR NATIVE True-FISP sequence can achieve similar effects with dynamic contrast-enhanced MRA in hepatic portal vein imaging.
