title: Correlation of computed tomography, echo-planar diffusion-weighted magnetic resonance imaging and surgical outcomes in middle ear cholesteatoma.
abstract: CONCLUSIONS
  Echo-planar diffusion-weighted magnetic resonance imaging (DW MRI) is more reliable than high-resolution computed tomography (HRCT) in predicting the presence and localization of cholesteatoma before tympanomastoid surgery.
  
  
  OBJECTIVE
  To evaluate the diagnostic accuracy of HRCT and echo-planar DW MRI in the detection and localization of cholesteatoma.
  
  
  METHODS
  Fifty-nine patients were prospectively included in this study. Patients with suspected primary cholesteatoma were evaluated by HRCT and echo-planar DW MRI before tympanomastoid surgery. Radiological findings were correlated with intraoperative findings.
  
  
  RESULTS
  HRCT and echo-planar DW MRI accurately predicted the presence or absence of cholesteatoma in 40/59 (67.8%) and 52/59 (88.1%) patients, respectively. The sensitivity, specificity, and positive and negative predictive values of HRCT were 68.97%, 66.67%, 66.67%, and 68.97%, respectively. However, sensitivity, specificity, and positive and negative predictive values of echo-planar DW MRI were 85.71%, 90.32%, 88.89%, and 87.50%, respectively.
