If an image of the scapula was underpenetrated, how should the technique be adjusted?

When an image of the scapula is underpenetrated, it means that the image appears too light and lacks sufficient contrast and detail, indicating that the x-ray beams did not adequately penetrate the tissue. To remedy this underpenetration, an increase in the penetrating power of the x-ray beam is necessary. This is typically achieved by increasing the kilovoltage peak (kVp) value, as a higher kVp increases the energy of the x-rays, allowing for better penetration through the denser tissues of the scapula.

On the other hand, adjusting the milliampere-seconds (mAs) involves changing the quantity of x-rays produced, which affects the overall density of the image but does not directly address the issue of penetration. For an underpenetrated image, increasing the kVp while potentially adjusting the mAs if necessary would lead to a better-quality image.

In the context of this question, the correct answer suggests a specific mAs and kVp combination that likely aligns with common technique charts used for imaging the scapula, ensuring that there is sufficient penetration and contrast in the resultant images. The selected values provide a balance suited to producing a well-penetrated image of the scapula, illustrating a careful approach to imaging technique adjustments.
