Overview
Although, high resolution CT scanning(HRCT) is the best tool to evaluate ossicular chain and tympanic cavity walls and mastoid itself, however, HRCT is unable to differentiate between different types of effusions in the tympanic cavity, also evaluation of cholesteatoma can be challenging. MRI in mastoiditis plays role in the detection of cholesteatoma, also when intracranial and some intratemporal complications are suspected. Specifically, MRI has shown superiority in assessing the severity of intracranial involvement and abscess border visualization. Both CT and MRI are used in the evaluation of mastoiditis and its complications.
