DWI

DWI is a useful technique for the evaluation of cholesteatomas. It can be used to detect them when the physical examination is difficult and CT findings are equivocal. Moreover, it is especially useful in the evaluation of recurrent cholesteatoma.

Non-EPI DWI assists in detection and evaluation of the lesion. Image dataset acquired at Siemens Aera 1.5 Tesla, courtesy of Bac Nguyen.
