Study Notes
Radiographic Errors
- Majority of radiographic errors fall into the category of positioning errors.
Vertical Angulation Errors
- Incorrect vertical angulation causes a type of artifact called "elongation" or "foreshortening".
Exposure Errors
- Insufficient exposure results in a blank image on the radiograph.
PID Alignment Artifact
- Consequence of PID alignment artifact on the radiograph is a blurred or distorted image.
Radiograph Image Errors
- Apices being cut off on the radiograph is a result of incorrect positioning of the PID.
- High density image (faint) on the radiograph is caused by overexposure.
Film Artifacts
- Dropped film corner causes a type of artifact called a "corner cut-off" or "film edge artifact".
- Distorted image on the radiograph is a result of incorrect film placement or incorrect film size.
Film Errors
- Film with no image at all is a result of underexposure or no exposure.
OPG Ghost Image
- The anatomical structure most often ghosted in an OPG ghost image is the vertebral column.
- OPG ghost image resembles the inverted and blurred shape of the imaged object.
Patient Movement Errors
- Patient movement during exposure leads to distortion on the radiograph.
Film Handling Errors
- Smudge resembling a fingerprint on the film is a result of handling the film carelessly.
- Yellowish brown discoloration on the X-ray film is an indication of outdated or expired film.
- Black line on the X-ray film is an indication of a film with a light leak or a hole.
Lead Apron Artifact
- Lead apron artifact seen in X-rays is caused by the lead apron being in the X-ray beam.
