MALLO, María Lourdes et al. 64 - Detector CT findings in the study of the ear. Rev. argent. radiol. [online]. 2010, vol.74, n.4, pp.367-374. ISSN 1852-9992.

The ear is a complex anatomic structure. Its study and understanding represent a constant challenge for the radiologist. As a consequence the computed tomography becomes an essential tool for its examination. Conventional tomographic examination with both axial and coronal reconstruction of the image allows a satisfactory visualization of the different structures. However, the study requires long periods of time for its acquisition and uncomfortable or intolerable positions for the patients. Moreover, the characterization of some structures of the ear becomes limited. Sixty-four slice multidetector computed tomography allows the optimal study of the small and complex ear anatomy. Volumetric acquisitions with 0.5 mm slices, with multiplanar reconstructions in the three basic plans, in tri-dimensional reconstructions and curved plans, allow detailed visualization of structures in a few seconds, thuf avoiding patient discomfort. Our purpose in this article is to demonstrate the utility of reconstructions particularly in oblique planes, and reaching an optimal visualization of the temporal bone.
