    Study Notes

    Radiographic Errors

    • The primary cause of most radiographic errors is patient positioning error.

    Technique and Projection Errors

    • A grid error is not a type of technique and projection error in radiography.

    Radiopaque Artifact Errors

    • A radiopaque artifact in a radiograph indicates a processing error.

    Film Handling Errors

    • A dropped film corner in a radiograph indicates a film handling error.
    • A black line in a radiograph indicates a film handling error, specifically a static electric discharge.

    Contrast Errors

    • An image with high and low contrast in radiography results from overexposure or underexposure error.

    Anatomical Structure Errors

    • The most common anatomical structure that appears ghosted in an OPG error is the vertebral body.

    Artifact Errors

    • A artifact that resembles its real counterpart, has the same morphology, but appears on the opposite side is a mirror image artifact.
    • A black line on the film indicates a static electric discharge error.
    • Patient's shoulders touching the cassette during exposure causes a patient positioning error.
    • Patient movement during exposure causes a positioning error, leading to distortion in the radiograph.

    Film Defects

    • A white spot or patch on the film indicates a film defect.
    • A smudge (finger print) on the film is a form of film defect error.
