Axial images of contrast-enhanced neck CT at the level of oropharynx reconstructed by using 30% adaptive statistical iterative reconstruction (A) and model-based iterative reconstruction (B). Note a decrease in the streak artifacts related to dental amalgam particularly in the region of the base of the tongue, parotids, and foramen magnum and a poorer definition of fat planes in the parapharyngeal space on MBIR images.
