Overview
On MRI scan of the head, orbital cellulitis is characterized by hypointense signal on T1-weighted images, and hyperintense signal on T2-weighted images.(RADIOPAEDIA) MRI has demonstrated equivilance to CT in diagnosing orbital disease and is also accepted as a gold standard diagnostic imaging modality. (Sephadari & Merck). .Although a magnetic resonance imaging(MRI)scan is safer in children since there is no risk of radiation exposure, the long acquisition time and the need for prolonged sedation make CT scan the imaging modality of choice.(EyeWiki)
