A 2.5-minute NeuroMix-based MRI protocol appears to be comparable to standard pediatric MR imaging for identifying clinically relevant intracranial abnormalities, according to research to be presented on Tuesday afternoon.
The study findings outline a way to reduce acquisition time and imaging artifacts, presenter Johannes Decker, MD, PhD, of Stanford University and colleagues suggested.
"Prolonged acquisition times and motion artifacts limit the use of MRI in the pediatric emergency department, frequently necessitating sedation, reducing workflow efficiency, or exposure to ionizing radiation of CT," the group noted.
To explore the use of a short MRI protocol in this population in the ED, Decker's team identified pediatric patients who underwent both a standard pediatric emergency department MRI protocol and NeuroMix over a one-year period, constructing a cohort of 100 studies that included 44 positives and 56 controls. Three radiologist readers reviewed both the standard and NeuroMix exams, and assessed diagnostic interchangeability.
Decker and colleagues found the following:
· Overall diagnostic accuracy was identical for NeuroMix and standard imaging (87.7%).
· Interreader agreement for identifying of clinically relevant findings was solid for both NeuroMix (κ = 0.65) and the standard protocol (κ = 0.73).
· Mean acquisition time was shorter for NeuroMix than for the standard protocol (median 2.67 minutes versus 15.26 minutes [p < 0.001]).
Attend this session to learn more about the potential for this fast MRI protocol for use among children in the ED.
