Abstract: Objective: To investigate the value of Multivane XD technique in liver T2-weighted imaging (T2WI). Methods: Fifty-six patients(29 men, 27 women; age ranged 25-84 years, average 54 years) underwent liver MR imaging including conventional T2WI and Multivane XD T2WI were analyzed. Sixteen patients had focal hepatic lesions (FHL). Qualitative analysis was performed by two abdominal radiologists. Overall image quality was scored 5-scales ranged from 1 to 5. Signal intensity of right lobe, left lobe and FHL, and background SD were measured. SNR_{right lobe}, SNR_{left lobe}, CNR_{right lobe}, CNR_{left lobe} and contrast between FHL and liver parenchyma were calculated and compared between Multivane XD T2WI and conventional T2WI. Results: Overall image quality score of Multivane XD T2WI was significantly higher than that of conventional T2WI [(4.70±0.50) vs (2.86±0.80), P=0.001]. SNR_{right lobe} and SNR_{left lobe} were significantly higher than those of conventional T2WI [(189.84±112.39) vs(3.52±70.08), P<0.001; (218.82±136.24) vs (28.70±96.97), P<0.001]. There was no significant difference in CNR_{right lobe}, CNR_{left lobe} and contrast [(4.30±51.86) vs (3.52±70.08), P=0.447; (24.68±82.61) vs (28.67±96.95), P=0.742; (2.94±1.43) vs (2.92±1.16), P=0.958] between Multivane XD T2WI and conventional T2WI. Conclusions: Multivane XD technique can reduce motion artifacts and improve the imaging quality of T2WI.
