Evaluation of Usefulness of an m-DIXON Technique during an Abdomen MRI Examination : A Comparison with an e-THRIVE Technique

Abstract

This research is conducted to identify whether an m-DIXON technique which is useful for an abdomen MRI examination compared with an existing e-THRIVE technique is a clinically useful or not. There was evaluated quantitative and qualitative to 84 subjects who had abdomen MRI exam due to their liver disease were conducted during a period from September in 2013 to February in 2014. First of all the quantitative evaluation, the m-DIXON technique's SNR was 90.42±16.90 and the e-THRIVE technique was 60.42±11.54 and the m-DIXON technique's CNR was 52.38±22.58 and the e-THRIVE technique was 46.31±20.25. Secondly in the qualitative evaluation, the m-DIXON technique's image quality was 4.06±0.34, a artifact was 3.64±0.22, and fat suppression was 4.16±0.15, the e-THRIVE technique's image quality was 3.14±0.35, a artifact was 3.06±0.38, fat suppression was 3.14±0.30. In conclusion, m-DIXON technique for abdomen MRI examination showed superiority over both SNR as a quantitative anaylsis, CNR and a qualitative analysis.
