“…Recent literature has shown the potential of ultra-low-dose imaging for detecting the mandibular canal at a CTDIvol of 1.74 mGy, 11 linear measurements for oral implant planning at 0.29 mGy, 12 13 CAD-model fabrication at 0.99 mGy, 14 and image-guided surgery at 0.76 mGy. 15 Furthermore, organ-based dose-modulation reduced the dose to the eye lenses by about 27%-50% at an equivalent CTDIvol, without reducing the image quality.…”

Purpose Maxillofacial trauma predominantly affects young adults between 20 and 40 years of age. Although radioprotection is a legal requirement, the significant potential of dose reduction in computed tomography (CT) is still underused in the clinical routine. The objective of this study was to evaluate whether maxillofacial fractures can be reliably detected and classified using ultra-low-dose CT. Materials and Methods CT images of 123 clinical cases with maxillofacial fractures were classified by two readers using the AOCOIAC software and compared with the corresponding results from post-treatment images. In group 1, consisting of 97 patients with isolated facial trauma, pre-treatment CT images at different dose levels (volumetric computed tomography dose index: ultra-low dose, 2.6 mGy; low dose, <10 mGy; and regular dose, <20 mGy) were compared with post-treatment cone-beam computed tomography (CBCT). In group 2, consisting of 31 patients with complex midface fractures, pre-treatment shock room CT images were compared with post-treatment CT at different dose levels or CBCT. All images were presented in random order and classified by 2 readers blinded to the clinical results. All cases with an unequal classification were re-evaluated. Results In both groups, ultra-low-dose CT had no clinically relevant effect on fracture classification. Fourteen cases in group 2 showed minor differences in the classification code, which were no longer obvious after comparing the images directly to each other. Conclusion Ultra-low-dose CT images allowed the correct diagnosis and classification of maxillofacial fractures. These results might lead to a substantial reconsideration of current reference dose levels.

Mandibular canal vs. inferior alveolar canal: Evidence‐based terminology analysis

et al. 2020

View full text Add to dashboard Cite

Introduction The mandibular canal, as it was formerly named in Terminologia Anatomica (TA), has also been called the inferior alveolar (nerve) canal in many scientific publications. This study was conducted to investigate how these terms have been understood in different regions and different areas of expertise and to discuss the appropriate future application of the term “mandibular canal.” Methods A literature search was conducted using PubMed, and articles using different terms for this structure were classified into two groups, inferior alveolar canal/inferior alveolar nerve canal (IAC/IANC) and the mandibular canal (MC). The 50 most recent articles in each group were included. Publication year, journal title, country of the first author, and affiliation of all authors were recorded in both groups for all 100 articles. Results There was a significant difference between the IAC/IANC and MC groups in the numbers of anatomy journals, other journals, and anatomy affiliations. Turkey published most frequently with a total of 15 articles, followed by Iran with 10 articles, and China/India/United States with seven each. When the six countries of the first author that had three or more publications in each group were compared, only Turkey appeared in both groups; otherwise, different countries were in the two groups. Conclusions Based on the results of this analysis, and considering that the tentative new term “inferior alveolar foramen” is used in the latest TA, we suggest that the mandibular canal should be renamed the “inferior alveolar canal.”

“…Iterative Bildrekonstruktionen mit komplexen mathematischen Rechenmodellen verbessern die Bildqualität von dosisreduzierten Untersuchungen und zeigen in Abhängigkeit vom verwendeten Algorithmus und der klinischen Fragestellung eine mögliche Dosiseinsparung von bis zu 80 % [22]. Für die Zahn-und Kieferheilkunde konnten bereits folgende indikationsspezifische ALADA-CT-Dosen (CTDIvol) ermittelt werden: Trauma Mittelgesicht 2,6 mGy [23,24]; Implantologie mit Detektion und Messgenauigkeit des Mandibularkanals 1,74 mGy [25] bzw. lineare Messgenauigkeit des Implantatbetts 0,29 mGy [26,27]; Herstellung von CAD-Modellen 0,99 mGy [28]; und Computer-assistierte Chirurgie 0,76 mGy [29].…”

ZusammenfassungZiel dieses Kurzreviews ist es, einen kompakten Überblick zum Thema Röntgenstrahlenschutz zu bieten. Für das Verständnis von Strahlenschutz sind Grundlagen der Physik der Röntgenstrahlung, ihrer biologischen Wirkung, sowie der Dosimetrie notwendig. Zu den deterministischen Gesundheitsrisiken zählen die Radiodermatitis und die posteriore, subkapsuläre Linsentrübung. Als stochastische Effekte werden eine mögliche Lebenszeit-attributable Risikoerhöhung von Krebserkrankungen v. a. für die erhöht strahlensensiblen Kinder und jungen Erwachsenen, sowie Frauen im gebärfähigen Alter diskutiert. Die EURATOM-Richtlinie 2013/59 verpflichtet alle EU-Mitgliedstaaten zu strenger rechtfertigender Indikationsstellung anhand wissenschaftlich basierter Guidelines, Anwendung und Review von diagnostischen Dosis Referenzwerten, sowie Dosismanagement unter Anwendung des „as low as reasonably achievable“ (ALARA) bzw. „as low as diagnostically acceptable“ (ALADA) Prinzips. Insbesondere Schnittbildgebung wie digitale Volumentomografie und Computertomografie erfordern durch die rasanten technischen Weiterentwicklungen zur Dosisreduktion einen kontinuierlichen, indikationsangepassten Optimierungsprozess von Untersuchungsprotokollen.
