DETECTABILITY AND ANATOMICAL CORRELATION OF MIDDLE EAR CHOLESTEATOMA USING NON ECHO PLANAR DIFFUSION-WEIGHTED IMAGING AND HIGH RESOLUTION COMPUTED TOMOGRAPHY

Abstract

This study was conducted to evaluate the role of non-echoplanar diffusion weighted imaging with apparent decient coefcient values and high resolution computed tomography in detection and anatomical extend of middle ear cholesteatoma, the extent of invasion of cholesteatoma using diffusion weighted imaging and high resolution computed tomography, and ability of MRI non-echoplanar DWI sequence unequivocally conrming the diagnosis of cholesteatoma. A cross sectional study with a t Materials and method: otal of 32 patients was conducted at Chettinad Hospitals and Research Institute's Department of Radiology between January 2020 and July 2021 after being diagnosed with chronic otitis media using otoscope as per inclusion and exclusion crietria . Written informed consent was taken to participate in the study, which was authorised by our institution's ethics committee. All statistical analyses we Results: re carried out on Microsoft Windows PCs using the SPSS, version 17. The descriptive data was represented using numbers and %ages. The data was expressed using the mean and standard deviation. To analyse qualitative data, the chi-square test was used. The screening test was carried out utilising a receiver operating characteristic (ROC) curve developed by the researchers. A p value 0.05 was judged statistically signicant on both sides of the equation. Combining DWI with HRCT is a Conclusion: valuable method for evaluating the soft tissue of the middle ear. It has high sensitivity and specicity for detecting all primary cholesteatomas in their various stages of development
