Study Notes
PA Chest Projection
- Rotation should be avoided in a PA chest projection because it can lead to obscured lung markings and altered cardiac silhouette, making diagnosis challenging.
Ensuring No Rotation
- To ensure no rotation in a PA chest projection, the following should be checked:
- The patient's shoulders should be parallel to the image receptor.
- The medial ends of the clavicles should be equidistant from the vertebral column.
- The spinous processes of the thoracic vertebrae should be midline and not rotated.
Challenges in Patients with Scoliosis and Kyphosis
- It is difficult to obtain a true PA chest projection in patients with scoliosis and excessive kyphosis because their spinal deformities can cause the patient's thorax to be rotated, making it challenging to position them correctly for a PA chest projection.
