“…The consensus across the literature is that MDCT is the imaging modality of choice for adult patients with complex facial bone trauma . The liberal use of MDCT has become a concern because the ED exceeds that of plain radiography at an average of 1.5–2.9 mSv per facial bone CT compared to 0.02–0.1 mSv for x‐ray .…”

“…The accumulative dose from facial bone trauma would increase over time due to ongoing imaging through the treatment and follow‐up phases . The substantial ED attributed to MDCT warrants ongoing research to optimise dose and prevent reversal of the risk‐benefit ratio . The dose to patients from MDCT depends upon the technique factors and protocols used; examples of average exposures are shown in Table …”

“…In response to the radiation burden of facial bone MDCT scans, a number of dose optimisation measures have been proposed. Potential solutions have continued to emerge over time as limitations are recognised . Trending research has examined the use of protocol changes in MDCT, as well as novel methods including the use of cone‐beam CT (CBCT), intraoperative CT, and dual‐source CT (DSCT) systems.…”

“…Another protocol‐based approach to dose reduction in the literature is the elimination of dedicated facial bone MDCT scans . It was proposed that head CT data performed as a part of initial trauma imaging, could be reconstructed using soft tissue and bone algorithms to adequately show the facial structures without rescanning the patient.…”

“…Image processing, artefact suppression of dental amalgam, multi‐planar reconstructions and 3D imaging, can be used to optimise spatial and contrast resolution and provide a comprehensive view of the facial anatomy (Fig. ) . This technology also allows for treatment planning and post‐operative assessments .…”

Trauma to the facial area accounts for a significant number of admissions to the emergency department. Diagnostic imaging is almost always required, and is critical in determining patient management. Multi‐detector computed tomography (MDCT) appears consistently in the literature as the gold‐standard imaging modality for facial bones, but results in a high radiation dose to the patient. This makes the application and advancement of dose reduction and dose optimisation methods vital. This narrative review presents a critical analysis of the literature concerning diagnostic imaging of facial bone trauma, with an emphasis on dose reduction methods for MDCT. Databases including Pubmed, Medline, Web of Science and Scopus were used to investigate this topic, with the key words: facial bone trauma, computed tomography (CT) imaging and dose reduction. Exclusion criteria included studies on nasal bone fracturing, dental imaging, elective surgeries and paediatric imaging. The literature shows overwhelming support for MDCT, given its accuracy, efficiency and ease of operation. Noise reducing reconstruction algorithms show promise as a successful method of dose reduction in facial bone imaging. Investigations of more innovative techniques also appear within the literature, including diagnostic cone‐beam CT (CBCT), intraoperative CBCT and dual‐source CT (DSCT), but further research is required to confirm their clinical value.

The purpose of this study was tried to remove the noise and improve the spatial resolution in the computed tomography (CT) by using anisotropic 2-dimensional (2D) diffusion based filter. We used 4-channel multi-detector CT and american association of physicists in medicine (AAPM) phantom was used for CT performance evaluation to evaluate the image quality. X-ray irradiation conditions for image acquisition was fixed at 120 kVp, 100 mAs and scanned 10 mm axis with ultra-high resolution. The improvement of anisotropic 2D diffusion filtering that we suggested firstly, increase the contrast of the image by using histogram stretching to the original image for 0.4%, and multiplying the individual pixels by 1.2 weight value, and applying the anisotropic diffusion filtering. As a result, we could distinguished five holes until 0.75 mm in the original image but, five holes until 0.40 mm in the image with improved anisotropic diffusion filter. The noise of the original image was 46.0, the noise of the image with improved anisotropic 2D diffusion filter was decreased to 33.5(27.2%). In conclusion improved anisotropic 2D diffusion filter that we proposed could remove the noise of the CT image and improve the spatial resolution.
