Study Notes
PA Wrist X-ray Positioning
- Correct positioning for a PA wrist X-ray: fingers should not be extended, and the hand should be arched slightly.
- Importance of avoiding extended fingers: to prevent superimposition of fingers over wrist bones.
PA Oblique Wrist X-ray
- Correct part position: wrist should be rotated 45° toward the affected side.
- Importance of including 2-3” of distal radius and ulna: to provide a full view of the wrist and forearm.
- Use of a sponge: to aid patients who are unable to hold the position.
Radiography Abbreviations
- CR stands for: Center Ray or Central Ray.
- OID stands for: Object to Image Receptor Distance.
- PA stands for: Posterior-Anterior or Anterior-Posterior.
Tangential Carpal Tunnel (Gaynor-Hart Method)
- Purpose: to visualize the carpal tunnel and its contents.
- Recommended CR angle: 15-20°.
- Aid for patient positioning: a sponge can be used to help the patient hold the position.
Lateral Wrist Carpals Evaluation
- Important visualization: the lateral wrist carpals should be well visualized without superimposition.
Fan Wrist 3 View Wrist Exam – Logical Order
- Hand position for PA Scaphoid with Ulnar Deviation: the hand should be in ulnar deviation.
Radiographic Anatomy
- PA Oblique Hand Lateral (lateromedial): the wrist part position should be perpendicular to the IR.
- Importance of visualization in the Fan Wrist 3 View Wrist Exam: the scaphoid bone and surrounding anatomy should be well visualized.
X-ray Projections
- Radial Deviation projection: the radial aspect of the wrist should not be foreshortened, and the radial styloid process should be included in collimation.
- Visualization in the Radial Deviation projection: the radial aspect of the wrist should be visualized without superimposition.
- X-table Lateral: a type of radiographic view that refers to a lateral view taken with the X-ray tube above the table.
