Abstract

Objective: In this study, we aimed to
identify the position in which temporal bone anatomical structures and
pathologies could be best visualized by applying reconstruction to
cross-sections obtained on an axial plane in temporal bone computed
tomography (CT) scans.




Methods: Sixty
patients were examined with temporal bone CT between July 2008 and
March 2009. We obtained multiplanar reformatted images by applying
retro-reconstruction on various planes from the axial plane sections.





Results: We
determined that the reconstructed images increased the anatomical and
pathological details and significantly contributed to evaluating the
relationship between anatomical structures and their pathologies with
other normal components.




Conclusion:
Obtaining multiplanar reformatted images by retro-reconstruction
decreased the need for visualization of coronal sections used in
standard temporal bone CT exams since the anatomical details were
diversified using the new planes. In addition, the dose of radiation
received by the patients and the duration of the examination could be
reduced by eliminating routine coronal plane sections and obtaining new
images using retro-reconstruction.
