CAMRT Radiography Practice Exam

What views are necessary for a post-biopsy chest x-ray?

1. Only PA view

2. PA with oblique views

3. PA x-ray inspiration/expiration

4. Lateral and AP views

The correct answer is: PA x-ray inspiration/expiration

The necessity of obtaining both a posterior-anterior (PA) view with inspiration and expiration after a chest biopsy is rooted in the requirement for a comprehensive assessment of the lungs and pleural space. The PA view taken during inspiration allows for a better visualization of the lung fields and any potential complications like pneumothorax, which can occur after a biopsy. In expiration, this view aids in assessing any air that may have been introduced into the pleural space and helps evaluate the lung's ability to expand properly. Together, these views provide crucial information about the patient's condition following the procedure, facilitating early detection of complications. While the other options might provide useful information in specific contexts, they do not encompass the critical combination of views needed to effectively monitor for the complications that can arise post-biopsy. For instance, relying solely on the PA view or using oblique views may miss critical details relating to lung dynamics, while lateral and AP views may not adequately substitute for the necessary assessment of lung expansion in both phases of respiration.
