Because of the complexity of the structures studied, imaging the temporal bone requires compliance with a number of image quality criteria, in order to achieve optimum spatial resolution of the most clinically relevant anatomical landmarks. On the other hand, limiting patient exposure to ionizing radiation is a growing concern for the medical world. The challenge here is twofold: to meet a certain number of image quality criteria, in order to achieve optimum spatial resolution for the most clinically relevant anatomical landmarks, while aiming to reduce the radiation dose delivered to patients as much as possible. Despite its routine use, few studies have compared the various commercially available solutions in terms of image quality or dose delivered, in daily practice. The primary objective of our study is a qualitative comparison of 7 different types of CT scans on 17 anatomical structures, useful in clinical practice, taking into account the contrast-to-noise ratio (CNR). The secondary endpoint was a comparison of radiation levels.
