If you cannot distinguish intervertebral spaces, what should you do?

• A. Rotate the image
• B. Invert the image
• C. Increase the resolution
• D. Look for patient artifacts

Answer: (B)

In the context of bone densitometry imaging, if intervertebral spaces are indistinguishable, inverting the image can be a useful approach to enhance the visibility of the anatomical structures. Inversion changes the contrast of the image, which can help differentiate between the vertebral bodies and the intervertebral spaces, making it easier to evaluate the region of interest.

This technique relies on the way different tissues interact with the imaging modality, allowing finer details to emerge when colors are reversed. By altering the visual characteristics of the image, clinicians can sometimes gain the clarity needed to identify key structures that might otherwise be obscured.

While other techniques like rotating the image or increasing the resolution might seem beneficial, they may not address the specific issue of distinguishing the intervertebral spaces as effectively as inverting the image does. Therefore, in situations where clarity is compromised, inverting the image is a strategic option to enhance diagnostic capability.
