Abstract

In vivo T-2, ADC, and MT properties of the GM and WM of the rat spinal cord were measured at 7T in the cervical region, The GM T-2, T-2GM = 43.2 +/- 1,0 msec is significantly reduced compared to the WM T-2, T-2WM = 57.0 +/- 1.6 msec. Diffusion is anisotropic for both GM and WM, with a larger ADC value along the cord axis (ADC(GM)//, = 1.05 +/- 0.09 10(-9) m(2) sec(-1) andADC(WM//) = 1.85 +/- 0.18 10(-9) m(2) sec(-1)) than perpendicular to this plane (ADC(GM perpendicular to) similar to 0.50 * 10(-9) m(2) sec(-1) and ADC(WM perpendicular to) similar to 0.18 * 10(-9) m(2) sec(-1)).The MT properties do not significantly differ between the WM and the GM, but allow one to distinguish the thin CSF layer from the WM, DWI with the sensitizing gradient perpendicular to the cord axis leads to the best contrast between GM and WM in the cervical region.
