简要总结
Previous studies demonstrated the high diagnostic value of non-echoplanar diffusion weighted magnetic resonance imaging (non-EP DWI) for residual cholesteatoma. However, limited data are available regarding a suitable length of imaging follow-up. The present study aimed to determine the optimal duration of non-EP DWI follow-up for residual cholesteatoma
详细描述
A retrospective, monocentric study was performed between 2013 and 2019 and included all patients regularly followed-up after canal wall-up tympanoplasty with at least two non-EP DWI performed on the same 1.5T MRI scanner. MR images were reviewed independently by two radiologists. Sensitivity and specificity values were calculated as a function of time after the surgery. Receiver operating characteristics (ROC) curves were analyzed to determine the optimal follow-up duration.

主要结局
MRI sensitivity and specificity values as a function of the duration of the follow-up
时间窗: 1 day
MRI sensitivity and specificity values as a function of the duration of the follow-up. Since no official recommendations are available in the literature, the decision regarding the number of MRIs and the time lapse between any two was left to the discretion of the surgeon
次要结局
- Receiver operating characteristics (ROC) curves(1 day)
