In the head/neck/mouth area, CT scanning is used for surgical planning for craniofacial and dentofacial deformities, evaluation of cysts and some tumours of the jaws/paranasal sinuses/nasal cavity/orbits, diagnosis of the causes of chronic sinusitis, and for planning of dental implant ...

Another common complication regards air-filled structures, such as sinuses and air cavities, due to their low-density nature and the resulting sharp transitions of attenuation values between surrounding tissue [8]. These challenges can lead to the presence of artefacts in the sCT images. Therefore,...

there are some troubles with CTA. One is an added radiation dose of approximately 2.5 mSV after the NCCT which is also 2.5 mSV (total of 5 mSV). Another is that intravenous contrast agents may probably cause contrast nephropathy, especially in patients with a history of nephropathy11....

Sharp delineation of vascular structures, especially cavernous and sigmoid sinuses as well as carotid and subclavian vessels reflect the high overall image quality and low noise level in the Biograph Vision images.

‘’Head and Neck’’ was used because the data acquisition for CT scans of the sinuses is done supine. The coronal cuts extend all the way down to the upper teeth to include the gums and the roots of the teeth. These cuts also include a significant portion of the parotid glands and ...
Mucosal thickening, soft tissue hyperdense masses in the nasal cavity and/or sinuses, and clear (uninvolved) ethmoid cells amid diseased cells, were significant CT features that characterized invasive fungal infection. Opacification of the sinus represented extensive disease with tissue necrosis. When ...
