Quantitative CNR and SNR analysis

	ss-DTI		rs-DTI		ss-DTI vs. rs-DTI
	Mean	SD	Mean	SD	P-value
Reader 1
SNR	6.08	2.35	6.57	2	0.558
CNR	0.5	0.11	0.52	0.09	0.624
Reader 2
SNR	6.1	2.53	6.49	1.97	0.475
CNR	0.5	0.1	0.54	0.1	0.709

For both sequences and readers, CNR and SNR are given as mean ± SD. Paired t-tests were performed to assess potential between group differences. CNR, contrasttonoise ratio; rs-DTI, readout-segmented echo planar diffusion-tensor imaging; SD, standard deviation; SNR, signal-to-noise ratio; ss-DTI, single-shot echo planar diffusion-tensor imaging.
