1. Iodine-based Dual-Energy CT of Traumatic Hemorrhagic Contusions: Relationship to In-Hospital Mortality and Short-term Outcome
A B
Quantitative DE CT parameters were associated with in-hospital mortality and short-term outcome for hemorrhagic contusions at hospital discharge (disability rating scale and Rancho Los Amigos scale).
On average, a one-unit (milligrams) increase in iodine quantity in pseudohematoma increases the odds of in-hospital mortality by 40% (OR, 1.4; P = .03).
A 1-mg increase in iodine quantity in contusions was associated with lower Rancho Los Amigos scale score by 0.04 per milligram (P = .01) and greater disability rating scale score by 0.19 per milligram (P = .02).
Unenhanced DE CT scans in a 25-year-old shows hemorrhagic contusion (arrow). Iodine overlay shows contrast staining of the penumbra of the contusions (black arrowheads) and helps demarcate from the epicenter (white arrowhead).
