CAMRT Radiography Practice Exam

What breathing instructions should be given for imaging upper ribs?

1. Expiration

2. Inspiration

3. Shallow breathing

4. Hold breath

The correct answer is: Inspiration

When imaging the upper ribs, the appropriate breathing instruction is to take a deep inspiration. This is important because during inspiration, the diaphragm moves down and the thoracic cavity expands, creating maximum separation between the ribs and enhancing the visibility of the upper rib structures on the radiograph. The increased lung volume can also help to elevate the ribs, thus reducing overlapping of bony structures and allowing for clearer imaging. Instructing the patient to breathe deeply helps to increase the contrast of the skeletal structures by expanding the thorax, which is crucial for obtaining optimal images of the upper ribs. This technique helps in achieving clearer delineation, making it easier to assess any potential pathologies or abnormalities in that area.
