Table 2 Sample content from the expert-designed OCT image interpretation examination

From: Immersive educational curriculum on intracoronary optical coherence tomography image analysis among naïve readers

Exam Content

 1. Identify the minimal lumen frame, MLA, MLD, and percentage area stenosis

 2. Identify the reference frame, reference lumen area, and reference mean diameter

 3. Identify the location of all observed branches by frame number

 4. Measure the minimal and mean FCT

 5. Measure the total calcium and lipid arcs

 6. Identify the presence of TCFA

 7. Characterize the plaque type as fibrotic, calcified, lipid, mixed, or no plaque

 8. Measure the length of TCFA as defined as < 65 µm

 9. Measure the length of TCFA as defined as < 100 µm

 10. Technical knowledge

  ▪ Image-based free text: identifying the OCT feature

  ▪ Multiple-choice: characterizing and identifying features of lipid plaque, plaque rupture, macrophages, white and red thrombus, and vessel wall layers
