Subjective image quality assessed by 5-point Likert scale

Image quality score	Group 300 s (range 1–5)	Group 150 s (range 1–5)	Group 60 s (range 1–5)	P value
Overall quality	4.79 ± 0.37	4.37 ± 0.55	3.21 ± 0.46	< 0.001
Image noise	4.67 ± 0.46	4.27 ± 0.52	2.73 ± 0.59	< 0.001
Lesion conspicuity	4.92 ± 0.27	4.62 ± 0.49	4.08 ± 0.74	< 0.001

All scores were presented as mean value ± SD and the images were reconstructed with a voxel size of 3.125 × 3.125 × 1.44 mm³
