ABSTRACT
BACKGROUND AND OBJECTIVES:
This study was to done to determine the value of PROPELLER diffusion-weighted imaging in detecting cholesteatoma. SUBJECTS ANDMETHOD:
Sixty-five patients were evaluated by preoperative magnetic resonance imaging (MRI) with PROPELLER diffusion-weighted imaging. Of 65 patients, 16 patients had chronic otitis media without cholesteatoma and 49 patients with cholesteatoma. Surgical and pathologic findings were compared with the preoperative findings by PROPELLER diffusion-weighted imaging to assess the sensitivity, specificity, positive and negative predictive values.RESULTS:
In 49 patients with cholesteatoma, high signal intensity compatible with cholesteatoma was found in 46 patients, whereas in 16 patients without cholesteatoma, high signal intensity was not detected in any of them. The sensitivity, specificity, positive and negative predictive values for PROPELLER diffusion-weighted imaging were 94.1%, 100%, 100%, and 84.2%, respectively.CONCLUSION:
PROPELLER diffusion-weighted imaging can be a useful tool in detecting cholesteatoma.
