What can happen if a neck block is placed too high during a scan?

Placing a neck block too high during a bone density scan can compromise the accuracy of the images captured, leading to a poor outline of the femoral head. This occurs because improper alignment can result in anatomy being misrepresented or excluded from the imaging field, which prevents the machine from capturing a clear representation of the area being studied.

In this scenario, the femoral head is a critical structure that must be visualized accurately for assessing bone density and identifying potential issues like osteoporosis or fractures. A misplacement of the neck block can obscure important anatomical landmarks, ultimately making it difficult for clinicians to evaluate the bone density results effectively.

Understanding the impact of positioning is crucial in imaging procedures, as correct placement is essential for producing reliable and interpretable images.
