TL;DR: MR imaging for detection of middle ear cholesteatoma can be performed by using non-EP DW imaging sequences alone, with no significant increases in sensitivity, specificity, NPV, or PPV over the use of the non- EP DW imaging sequence alone.

Abstract: MR imaging for detection of middle ear cholesteatoma can be performed by using non–echo-planar diffusion-weighted imaging alone, avoiding the need for contrast agent administration; this technique has much higher sensitivity than delayed gadolinium-enhanced T1-weighted MR imaging.

TL;DR: The removal of high intensity noise with image processing on cDWI could improve cholesteatoma-background contrast-to-noise ratio (CNR) and noise reduction was performed by the cut-off values of apparent diffusion coefficient less than 0 and 0.4 × 10−3 s/mm2.
Zastosowanie badania rezonansu magnetycznego w sekwencjach dyfuzyjnych do oceny chorych po operacji zamkniętej z powodu perlaka
TL;DR: Non EPI MRI DWI can be used as a screening tool to detect residual or recurrent cholesteatoma and may substitute the need of second look surgery in patients after canal wall up surgery due to cholsteatoma.

Colesteatoma: utilidade da sequência de difusão sem echo- planar*
TL;DR: Non-echo-planar diffusion‑weighted imaging represents an alternative to resolve the problem of air-bone interface in the mastoid region, once this method is less subject to this type of artifact.
Importance of diffusion weighted magnetic resonance imaging at differentiation of cholesteatoma and granulation tissue in patients with chronic suppurative otitis media
TL;DR: Echo-planar diffusion-weighted imaging by using ADC and DWI is a valuable tool with high sensitivity and specificity rates in detecting cholesteatoma particularly bigger than 5 mm and in differentiating them from other pathologies.

TL;DR: The objective of the present study was to evaluate the long-term outcomes of the surgical treatment of chronic suppurative otitis with cholesteatoma in terms of prevention of a residual disease and its relapses.

The measurement of observer agreement for categorical data
J. R. Landis,Gary G. Koch +1 more
TL;DR: A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.

Usefulness of Delayed Postcontrast Magnetic Resonance Imaging in the Detection of Residual Cholesteatoma after Canal Wall‐Up Tympanoplasty
TL;DR: Assessment of the usefulness of magnetic resonance imaging using delayed postcontrast T1‐weighted images for the detection of residual cholesteatoma after canal wall‐up tympanoplasty (CWU) in cases where CT was not conclusive.

Detection of postoperative relapsing/residual cholesteatomas with diffusion-weighted echo-planar magnetic resonance imaging.
TL;DR: EPI-DWI may be a useful tool in differentiating between cholesteatomatous and noncholest eatery tissues after closed cavity mastoidectomy, and further investigations are, however, required to establish the practical utility of EPI-D WI on larger series as a screening modality in the follow-up after closed body mastoidectomies.

TL;DR: In this article, the authors used delayed postcontrast Tl-weighted images for the detection of residual cholesteatoma after canal wall-up tympanoplasty (CWU) in cases where CT was not conclusive.

Comparison of Echo-Planar Diffusion-Weighted Imaging and Delayed Postcontrast T1-Weighted MR Imaging for the Detection of Residual Cholesteatoma
TL;DR: Both techniques gave acceptable results for residual cholesteatoma detection and may benefit patients by avoiding undue surgery, and DWI is more specific but less sensitive than DPI.
