This study investigated how changes in field of view (FOV) and voxel size impact the ability of cone-beam computed tomography (CBCT) scans to detect erosions in the temporomandibular joint (TMJ).
A total of 32 TMJs, including both erosive and normal cases, were analyzed using three different imaging protocols, with the scans evaluated by two radiologists for erosion presence.
Results showed that the 6-in FOV protocol had the best diagnostic efficacy compared to the larger FOVs, and it also had the lowest effective radiation dose among the imaging options tested.
