Overview

Randomized trial compares HRCT and non-EPI DWI-MRI for cholesteatoma diagnosis, indicating improved preoperative evaluation.

Key Points

  • This study aims to compare the diagnostic effectiveness of HRCT and non-EPI DWI-MRI for middle ear cholesteatoma and their combined use for preoperative assessment.
  • Retrospective analysis of imaging data from 85 subjects, including 65 with confirmed cholesteatoma.
  • Comparison of HRCT and non-EPI DWI-MRI interpretations against reference standards.
  • Assessment of diagnostic metrics such as sensitivity, specificity, accuracy, and interobserver agreement (κ).
  • HRCT exhibited high sensitivity (95.4%) for detecting bony erosions and ossicular abnormalities.
  • Non-EPI DWI-MRI showed greater specificity (85.0%) in differentiating cholesteatoma from other soft tissues.
  • Combined HRCT+DWI-MRI demonstrated optimal performance: sensitivity 93.8%, specificity 92.0%, accuracy 93.2%, with a localization error of 1.8 mm.
