Mean apparent diffusion coefficient (ADC) (± standard deviation) and coefficient of repeatability values obtained in a doped water phantom for each of the diffusion-weighted imaging sequences investigated

Measurement	Echoplanar imaging	RESOLVE	ZOOMit
ADC	1.910 ± 0.026	1.875 ± 0.025	1.891 ± 0.039
Short-term repeatability	0.0155 (0.80%)	0.0125 (0.66%)	0.0597 (3.11%)
Long-term repeatability	0.0620 (3.26%)	0.0667 (3.57%)	0.1183 (6.27%)

All units are ×10⁻³ mm² s⁻¹; percentage values are also given with respect to the corresponding mean values for data used in repeatability calculations.
