Identification of residual–recurrent cholesteatoma in operated ears: diagnostic accuracy of dual-energy CT and MRI

The aim of this study was to compare the diagnostic accuracy of magnetic resonance imaging (MRI) and dual-energy computed tomography (DECT) to identify residual–recurrent cholesteatoma using the second-look surgery as the reference standard. This prospective, institutional review board-approved study included 19 consecutive patients (11 males and 8 females; mean age of 62.2, range 34–80 years). Since five patients were studied bilaterally, a...
