Abstract:

Objective The study aimed to investigate the application value of 3D free breathing pinwheeltechnology（Multi Vane XD）combined with chemical shift technology hydrolipid separation imaging （Dixon）sequence in cervical magnetic resonance（MR）enhancement. Methods A total of 61 patients underwent neckMRI scans using 3D MultiVane XD Dixon sequence and conventional T1WI frequency attenuated inversion recovery（SPAIR）enhanced sequence. The image quality of enhanced T1WI sequences in the two groups were scored andstatistically analyzed. Results In terms of fat suppression and image artifacts，the image quality score of 3DMultiVane XD Dixon sequence was higher than that of conventional T1W SPAIR sequence，and the difference wasstatistically significant（P < 0.05）. It was higher than 3D MultiVane XD Dixon sequence and the difference wasstatistically significant（P < 0.05）. Conclusion 3D MultiVane XD Dixon sequence could significantly reduceneck MR ⁃ enhanced swallowing and breathing，vascular pulsation and metal susceptibility artifacts，which has agood fat suppression effect.
