Abstract:
Objective To compare the image quality of half-fourier acquisition single-shot turbo spin-echo(HASTE)sequence based on deep learning(DL)reconstruction algorithm(HASTE-DL)sequence with conventional BLADE turbo spin echo(TSE)(BLADE-TSE)sequence in liver T2WI scanning,and to explore the application value of HASTE-DL sequence.Methods Forty-four patients underwent liver BLADE-TSE and HASTE-DL sequences scanning and the image quality was subjectively and objectively evalua-ted.The image overall quality,detail sharpness,liver anatomical sharpness,bile duct clarity and artifacts of the two sequences were qualitatively scored by the quadripartite method for subjective evaluation.The objective evaluation included quantitative analysis of the signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR)and scanning time of the two sequences.Results There were no sig-nificant differences in image overall quality,liver anatomical sharpness and artifacts scores between the two sequences(P＞0.05).Compared to the BLADE-TSE sequence,the score of the image bile duct clarity of the HASTE-DL sequence was higher(P＜0.001),how-ever the detail clarity of the HASTE-DL sequence was lower(P＜0.001).In addition,both the SNRliver and CNRliver/erector spinal muscle of the HASTE-DL sequence were better(P＜0.001).The scanning time of the HASTE-DL sequence was much shorter.Conclusion Compared with BLADE-TSE sequence images,the overall quality of HASTE-DL sequence images meets the diagnostic requirements,with higher bile duct clarity,better SNRliver and CNRliver/erector spinal muscle,and shorter scanning time.Thus,HASTE-DL sequence can be used as a supplement to conventional BLADE-TSE sequences for liver MRI scanning.
