PURPOSE: To find out the utility of cervical backbone MRI in blunt trauma analysis for instability after a damaging non-contrast cervical backbone CT.
METHODS: A overview of medical data recognized all grownup sufferers with blunt trauma who underwent CT cervical backbone adopted by MRI inside 48 h over a 33-month interval. Utility of subsequent MRI was assessed by way of findings and affect on final result.
RESULTS: A complete of 1,271 sufferers with blunt cervical backbone trauma underwent each cervical backbone CT and MRI inside 48 h; 1,080 sufferers have been included within the examine evaluation. Sixty-six p.c of sufferers with a CT cervical backbone examine had a damaging examine. Of those, the next cervical backbone MRI had optimistic findings in 20.9%; 92.6% had steady ligamentous or osseous accidents, 6.zero% had unstable accidents and 1.three% had probably unstable accidents. For unstable damage, the NPV for CT was 98.5%. In all 712 sufferers present process each CT and MRI, only one.5% had unstable accidents, and solely zero.42% had vital change in administration.
CONCLUSIONS: MRI for blunt trauma analysis stays not rare at our establishment. MRI could have utility solely in sure sufferers with persistent irregular neurological examination.
KEY POINTS: • MRI has restricted utility after damaging cervical CT in blunt trauma. • MRI is regularly optimistic for non-specific soft-tissue damage. • Unstable damage missed on CT is rare.
