Abstract Objective: To evaluate the value of Dixon-VIBE technique in cervical enhanced scanning. Methods: Eighty patients underwent cervical contrast-enhanced MRI scanning were divided into four groups randomly, using the Simens Skyra 3.0T MR imaging instrument and the 16 channels head and neck coil for the routine axial and coronal scanning and enhanced scanning. T1-FS-TSE, T1-Dixon-TSE, T1-FS-VIBE and T1-Dixon-VIBE(in turn as S1, S2, S3, S4) were performed in enhanced scanning. All post-enhancement images were evaluated and analyzed subjectively and objectively. The subjective evaluation includes resolution of soft tissue, fat suppression homogeneity and artifact of blood vessels. The objective evaluation includes image noise, signal to noise ratio(SNR) and contrast to noise ratio(CNR). Result: The difference of resolution of soft tissue, fat suppression homogeneity and vascular artifact control in the four groups were statistically significant(P<0.01). The difference of image noise, SNR and CNR among different parameter setting groups were statistically significant(P<0.01). Conclusion: The Dixon-VIBE technique can improve overall image quality and provide more signifcant information for the clinical diagnosis.
