Impaired Limb Functional Outcome of Peripheral Nerve Regeneration Is Marked by Incomplete Recovery of Paw Muscle Atrophy and Brain Functional Connectivity in a Rat Forearm Nerve Repair Model

Table 1

Establishing the optimal sequencing parameter for measuring the forepaw intrinsic muscle volume.

Parameter	Sequence	Resolution (mm)	FoV read (mm)	FoV phase (%)	Slice thickness (mm)	SNR	TR (ms)	TE (ms)	Confidence of the segmentation					Total time (mm:ss)
									Rater 1	Rater 2	Rater 3	Rater 4	Average score
1	TSE		35.00	79.70	1.20	1.00	2000	24	1	2	2	1	1.5	28:18
2	GRE		130.00	100.00	1.00	5.25	28	4	2	1	1	2	1.5	13:18

We did not further increase the resolution of the TSE scanning sequence, due to the tremendous amount of imaging time (>28 min) at this parameter.
