Procedure:
A standardized MRA scanning protocol with an echo time of <5
msec was implemented at Montefiore Medical Center in May 2016.
Retrospective chart review identified 29 patients ≤ 21 years with SCA
cerebral vasculopathy and an MRA head pre- and post-May 2016. Level of
arterial stenosis on MRA, echo time, and treatment plans were documented
both pre- and post-implementation. McNemar analysis determined the
significance of change in treatment plans before and after
implementation of the standardized scanning protocol.
