PA (posteroanterior) projection means the X-ray beam enters the posterior (back) of the patient and exits the anterior (front). AP (anteroposterior) is the opposite, with the beam entering the front and exiting the back. PA is preferred for chest X-rays as it minimizes heart magnification and provides a more accurate representation of thoracic anatomy. AP is often used for bedridden or immobile patients.
Check that the medial ends of the clavicles are equidistant from the spinous processes on the image. This symmetry confirms proper patient positioning. Additionally, ensure the patient’s shoulders are level and aligned with the image receptor.
Adapt positioning techniques based on the patient’s condition, communicate calmly and clearly, and use immobilization devices if necessary. Collaboration with other staff may also help ensure safety and image quality.
Use the ABCs approach:
- Anatomy: Ensure all necessary anatomy is included.
- Brightness/Contrast: Check for proper exposure.
- Centering/Collimation: Confirm alignment and field of view.
Ensure the image is free from artifacts and meets diagnostic standards.
They may accompany the patient but they will have to stand behind the barrier.
Before the patient enters the room, it is important to make sure the x-ray board is wiped to ensure that everything is sanitary.
If the patient insists on what the radiographer thinks about the images, please remind them that you are not allowed to disclose your thoughts, only the doctor can officially diagnose the patient.
