Troubleshooting Cone-beam Computed Tomography Imaging: A Review

Abstract

Introduction: Artifacts in radiology refer to the unwanted structures or the discrepancies that appear in the diagnostic image, resulting in
obscuring the region of interest to be studied. This usually occurs when the gray scale values in the image do not display precisely the diminution
values of the content in the persons to be studied. Artifacts sometimes also appear as foreign structures that are not present in the region of
interest and are outside structures such as ear rings or other accessories. Since their presence deteriorates the image quality, the knowledge of
their presence alerts a radiologist, so that the findings should not get misinterpreted and diagnosis should become flawless.
Aim: The aim of this review is to ascertain the possible factors which give rise to the various artifacts in the radiographic image and lead to the
misinterpretation of the CBCT image.
Conclusion: The knowledge of various cone-beam artifacts is essential to limit a clinician in misdiagnosing a pathological condition and to help
an astute clinician in proper treatment planning.
