Diffusion-weighted imaging – ADC values from intramedullary lesions and normal appearing cord on initial presentation and subsequent follow-ups in three patients.

Patient number	Intramedullary lesion/normal cord ADC values 1. On presentation (mean ± SD)	Intramedullary lesion/normal cord ADC values On follow-ups (mean ± SD)
5	1.40 ± 0.17/1.01 ± 0.15 3.	1.64 ± 0.07/1.23 ± 0.04
7	1.27 ± 0.09/1.19 ± 0.18	1.31 ± 0.01/1.23 ± 0.02
9	1.18 ± 0.02/1.16 ± 0.10	1.21 ± 0.07/1.23 ± 0.04
Average	1.28 ± 0.092/1.16 ± 0.014	1.38 ± 0.055/1.23 ± 0.033

ADC: apparent diffusion coefficient.
