CAMRT Radiography Practice Exam

When imaging the kidneys, is the PA projection a viable option? What is the reason?

1. Yes, because it minimizes organ distortion.

2. No, because the kidneys appear magnified in this view.

3. Yes, as it provides a clearer image of the renal system.

4. No, as it fails to highlight other organs effectively.

The correct answer is: No, because the kidneys appear magnified in this view.

The reason the PA projection is not ideal for imaging the kidneys is primarily due to the magnification effect it causes. In this projection, the kidneys are positioned further from the imaging plate (film), which can lead to a distorted and enlarged appearance. This magnification compromises the clarity and accuracy of the anatomical representation, making it challenging to assess the size and function of the kidneys properly. Additionally, the PA projection does not provide the optimal angulation for visualizing the kidneys, which are located at a slight angle in the body. A different projection, such as an AP (anterior-posterior) view, can deliver a more accurate image and better representation of kidney anatomy. This enables improved visualization of the renal structure while minimizing distortion and magnification, thus offering a clearer assessment of the renal system.
