The study tested the estimation accuracy of Neurite
orientation dispersion and density imaging (NODDI) using
a common 2-shell protocol with the same gradient
direction at each shell. The experiment used visual and
quantitative comparisons to demonstrate that the common
2-shell protocol had very similar performance as the
optimized NODDI protocol, but is easy to configure in a
commercial scanner, thus can be widely adopted in
clinical study.
