EPI-DWI may be a useful tool in differentiating between cholesteatomatous and noncholesteatomatous tissues after closed cavity mastoidectomy. Further investigations are, however, required to establish the practical utility of EPI-DWI on larger series as a screening modality in the follow-up after closed cavity mastoidectomies.

SIRIO proved to be a reliable and effective tool when performing CT-guided PLBs and was especially useful for sampling small ([Formula: see text]20 mm) lesions.

• Navigation systems are useful tools in percutaneous imaging-guided procedures. • For lung biopsies, low-dose (LD) CT protocols may be used. • Combining LD protocols with optical CT navigation results in significantly reduced radiation exposure.
