What breathing technique is recommended for thoracic spine radiographs?

• A. Deep inspiration
• B. Breath-hold on expiration
• C. Free breathing
• D. Expose on expiration

Answer: (D)

The breathing technique for thoracic spine radiographs focuses on reducing diaphragmatic overlap and motion to make the vertebrae clearer. Exposing on expiration moves the diaphragm up and deflates the lungs, which lowers the amount of lung tissue overlying the lower thoracic spine. That upward displacement of the diaphragms and reduced lung volume lessen shadowing and blur from breathing, giving a sharper view of the vertebral bodies and intervertebral spaces. Having the patient hold or momentarily stabilize at end-expiration helps minimize motion during exposure, further improving detail. Deep inspiration would push the diaphragms downward and inflate the lungs, increasing overlap and potential blurring of the thoracic spine. Free breathing introduces more motion and inconsistent anatomy from breath to breath. A breath-hold on expiration achieves a similar effect, but the conventional technique described for this view is to expose on expiration to ensure the diaphragms sit higher and the spine is seen with better clarity.
