Modified Denver BCVI (Cothren 2005)
Modified Denver BCVI (Cothren 2005). Positive if any sign (arterial hemorrhage; cervical bruit age <50; expanding cervical hematoma; focal deficit; neuro exam incongruous with head CT; stroke on secondary CT) or any risk factor (LeFort II/III; C-spine subluxation, transverse foramen, or C1-C3; basilar skull with carotid canal; DAI with GCS <6; near hanging with anoxia). Imaging indicated when positive. Not Biffl grade, expanded Denver, NEXUS, or Canadian C-spine. magent does not read CTA.
