Abstract
To investigate the application value of 3D free-breathing starVIBE technology in enhanced MRI scanning of neck.From April 2022 to March 2023,the data of enhanced neck MRI from 41 patients were prospectively collected in Beijing Tongren Hospital Capital Medical University.3D free breathing starVIBE enhanced and TSE Dixon fat suppression enhanced T1-weighted imaging were performed using 3.0T MR Scanner and 16-channel combined head-and-neck coils.The image quality of the two groups was evaluated.The objective evaluation was to calculate the signal intensity and background noise of the lymph nodes and the erector ridge muscle of the corresponding layer in the tissue,and calculate the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the images.The subjective evaluation was a series of subjective scores,which including the degree of fat suppression,mucosal enhancement,muscle edge clarity,vessel clarity,lesion edge sharpness,lesion sharpness,respiration and swallowing motion artifact,vascular pulsation artifact,and overall image quality.Independent sample t test or Wilcoxon rank sum test were used to compare the differences in objective indicators and subjective scores between the two groups of images.The SNR of lymph nodes in TSE_T1WI-Dixon group was higher than that in 3D-starVIBE group(P＜0.001),there was no significant difference between muscle SNR of 3D-starVIBE group and TSE_T1WI-Dixon group(P=0.341＞0.05),and the CNR of TSE_T1WI-Dixon group was higher than that in 3D-starVIBE group(P＜0.001).There was no significant difference in the scores of fat suppression,mucosal enhancement and lesion sharpness between 3D-starVIBE group and TSE_T1WI-Dixon group(P＞0.05).The following parameters were scored as significantly better for the 3D-starVIBE group than for the TSE_T1WI-Dixon group:muscle edge clarity,vascular clarity,lesion edge clarity,respiration and swallowing motion artifact,vascular pulsation artifact and overall image quality(P＜0.001).Weighted Kappa coefficients were 0.616-0.863(P＜0.001).3D free breathing starVIBE enhanced sequences can reduce the neck respiration and swallowing motion artifacts and vascular pulsation artifacts,improve ability of demonstrating the neck soft tissue clarity,and can be used in clinical practice as a supplement or alternative to provide more confidence in diagnosis.关键词
