ABSTRACT
Objective:
To compare and analyze the image quality, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of T 1WI_Star_VIBE_FS sequence in MRI simulation of neck tumors with different scanning methods, aiming to determine the optimal scanning method.Methods:
A retrospective analysis of 78 patients receiving MRI contrast scan was performed. All patients were randomly divided into three groups according to three different scanning methods including bolus mode (group A, n=23), segmentation splicing mode (group B, n=18) and the combination mode (group C, n=37). The image quality, SNR and CNR of the anterior soft tissues of neck were statistically compared.Results:
A higher image quality score was obtained in group C. The mean SNR and CNR in three groups were calculated as 214.70±148.78, 91.95±59.26, 307.61±127.80, and 208.74±148.27, 85.79±59.50, 301.58±127.48, respectively. The image quality score, SNR and CNR in group C were significantly better compared with those in group A and B (all P<0.01).Conclusion:
Combination of bolus and segmentation splicing modes is a recommended approach in MRI simulation during radiotherapy of neck tumors.
