The feasibility of dynamic single line
acquisition of diffusion tensor parameters is
demonstrated in a flow phantom and in in vivo
skeletal muscle on a 3T clinical scanner. This
method, Single Line Multiple Echo Diffusion
Tensor Acquisition Technique SL-MEDITATE),
encodes each of multiple echoes generated by
five RF-pulses with different diffusion
weighting. A single line is selected by
orthogonal slice selective gradients. The
resulting dynamic acquisition can be used to
study the transient changes in diffusion tensor
parameters, such as in muscle tissue following
exercise, where traditional DTI methods lack
temporal resolution.
