Computed Tomography01:10

Computed Tomography

9.0K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Dentistry and Oral Surgery
  • Radiology and Imaging

Background:

  • Cone beam computed tomography (CBCT) is widely used in oral and maxillofacial surgery.
  • Artifacts in CBCT imaging can compromise diagnostic accuracy and surgical planning.

Purpose of the Study:

  • To systematically review the impact of CBCT artifacts on oral and maxillofacial surgical planning and follow-up.
  • To present illustrative cases of CBCT artifact-related challenges.

Main Methods:

  • Systematic literature search of MEDLINE (PubMed) from February 2004 to February 2017.
  • PRISMA guidelines followed for data extraction and assessment.
  • Analysis of 11 eligible studies and 4 illustrative cases.

Main Results:

  • Three primary artifact types identified: beam hardening, streak, and motion.
  • Most studies indicate significant negative effects of artifacts on surgical planning and follow-up.
  • CBCT remains valuable for identifying metal projectiles in trauma cases despite artifacts.

Conclusions:

  • CBCT artifacts pose a significant challenge to the reliability of oral and maxillofacial surgical planning and follow-up.
  • Awareness and mitigation of artifacts are crucial for optimizing CBCT use in surgical contexts.
