About this Program

Chest radiography continues to be the most frequently ordered imaging exam due to its accessibility, low cost, low radiation dose, and high diagnostic value. This webinar explores foundational image assessment strategies used by radiologists to analyze chest radiographs, as well as the crucial contributions technologists make to ensure diagnostic-quality images. Participants will learn how to recognize radiographic patterns and anatomical landmarks that aid in the localization of pathology.

Concepts such as the Silhouette Sign, hilar overlay, cardiac curves, and chest consolidations will be reviewed, along with techniques for evaluating image quality and patient positioning. The session emphasizes the technologist's role in optimizing exposure, respiration, and positioning—factors that directly influence the diagnostic potential of each radiograph.

Agenda:

  • Principles of Chest Image Assessment
  • Five Radiographic Densities and Their Applications
  • The Silhouette Sign and Related Radiographic Concepts
  • Types and Indicators of Chest Consolidation
  • Cardio-Thoracic Ratio and Radiographic Analysis
  • Identification of Cardiac Curves and Anatomical Landmarks
  • Evaluation of Chest Lines, Stripes, and Other Key Structures
  • Structured Approaches to Reviewing Chest Radiographs
  • Technologist Strategies for Enhancing Diagnostic Image Value
    • Positioning, Respiration, and Exposure Techniques
    • Indicators of Image Rotation and Quality Variations

  • Recognize abnormal chest radiographs using the Silhouette Sign concept
  • Identify the general location of chest consolidations using the Silhouette Sign and hilar overlay techniques
  • Distinguish between the four classes of chest consolidations
  • Diagram the pulmonary acinus to explain the process of fluid accumulation and aeration in lung tissues
  • Calculate the cardio-thoracic ratio and explain its significance
  • Label the left and right cardiac curves seen on chest radiographs
  • Identify key anatomical structures commonly seen on chest radiographs
  • Explain the technologist’s role in maximizing image quality and the consequences of suboptimal imaging
