Imaging Studies I: CT and MRI

641
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

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
  • Radiology
  • Medical Imaging

Background:

  • Cone beam computed tomography (CBCT) is widely used in dentomaxillofacial applications.
  • Variations in CBCT hardware and software protocols exist across different manufacturers and models.
  • Standardization is lacking, leading to potential inconsistencies in image quality and diagnostic outcomes.

Purpose of the Study:

  • To critically review the clinical challenges associated with patient-specific and indication-oriented dentomaxillofacial CBCT.
  • To highlight the impact of unit and protocol variability on diagnostic accuracy and treatment planning.
  • To emphasize the importance of artifact management and appropriate CBCT selection for specific clinical indications.

Main Methods:

  • This study is a critical review of existing literature on dentomaxillofacial CBCT.
  • Analysis of factors influencing image quality, diagnostic accuracy, and 3D model precision.
  • Evaluation of challenges related to specific clinical indications and artifact reduction.

Main Results:

  • Significant variations in CBCT units and protocols lead to variable diagnostic and 3D model accuracy.
  • Specific indications present unique challenges for CBCT unit and parameter selection, affecting image quality, segmentation, and artifacts.
  • Artifacts from dental materials are a major concern, influencing CBCT system choice.
  • Heterogeneity in CBCT performance impacts the generalizability of research findings.

Conclusions:

  • Clinical application of CBCT requires careful consideration of unit-specific performance and indication-based requirements.
  • Findings from one CBCT unit cannot be directly extrapolated to another due to performance heterogeneity.
  • Standardized protocols and further research are needed to ensure reliable and reproducible dentomaxillofacial CBCT imaging.
