Study Notes

Upper Limb Imaging

For upper limb imaging, the recommended exposure factors are those that ensure sufficient density.
The ideal positioning principle for correct centering is to align the central ray with the area of interest.
The recommended routine protocols for upper limb imaging include using a 4-sided collimation to reduce scatter radiation and improve image quality.
For trauma and post-reduction imaging, the recommended protocol is to use a high-contrast technique to visualize fractures and soft tissue injuries.

Patient Considerations

When imaging pediatric patients, consider using sedation or immobilization to reduce motion and ensure accurate imaging.
When imaging geriatric patients, consider their physical limitations and potential cognitive impairments.
For trauma patients, ensure accurate imaging by considering the patient's injuries and potential internal injuries.

Radiation Protection

'ALARA' stands for As Low As Reasonably Achievable, which means using the lowest radiation dose possible to produce a diagnostic image.
A recommended technique for radiation protection is to use the 4-sided collimation to reduce scatter radiation and improve image quality.

Markers and Positioning Aids

The recommended marker placement for radiographic imaging is to place markers on the image receptor to identify the patient's orientation and position.
Positioning aids like sponges, tongue depressors, tape, and cotton swabs are used to help position the patient correctly and comfortably.

Image Receptor and Exposure Factors

The recommended type of image receptor (IR) for capturing images during a radiography procedure is a digital image receptor.
The recommended exposure factor for upper limb imaging is to use a high kVp to avoid shape and size distortion.
The principle of isocentrism helps avoid shape and size distortion in radiography by keeping the source-to-image receptor distance (SID) consistent.

General Considerations

Patient possessions like rings, watches, bracelets, and long sleeve clothing should be removed before an x-ray to avoid artifacts.
The recommended source-to-image receptor distance (SID) for radiography is 40 inches (100 cm) to ensure accurate imaging.
The patient should be positioned comfortably and correctly to ensure accurate imaging.
