Abstract:
Objective To investigate the value of multi?arterial phase differential sub?sampling with cartesian ordering (DISCO) technique in the evaluation of hepatic vascular anatomy with gadolinium?ethoxybenzyl?diethylenetriamine pentaacetic acid (Gd?EOB?DTPA). Methods Forty?eight patients with suspected hepatic malignancy were prospectively enrolled and underwent both of Gd?EOB?DTPA enhanced DISCO MRI and CTA within two weeks. The hepatic arterial anatomy of two examination methods were evaluated by four?point scoring method. The arterial scores between DISCO and CTA images were compared by Wilcoxon test. The difference among multiple arterial scores of DISCO and CTA were compared by Kruskal?Wallis H test respectively. Results There was no difference of arterial scores in celiac artery, common hepatic artery, proper hepatic artery, left hepatic artery, right hepatic artery, first branch of right hepatic artery, splenic artery, left gastric artery and gastroduodenal artery between DISCO and CTA (P>0.05), but the arterial score of first branch of left hepatic artery [2 (2,2)] was lower than that of CTA [2 (2,3)] (Z=-3.138,P=0.002). In the multiple comparison among different arteries, there were differences between PHA and LAH (P<0.05), B?LHA and B?RHA (P<0.05) in DISCO, but no difference was found in CTA (P>0.05). Conclusion The DISCO sequence with Gd?EOB?DTPA enhancement MRI can supply comparable image quality to CTA in hepatic artery and its main branches display, which has no ionizing radiation and can also provide more diagnostic information for clinic.
