What Is the Difference Between Long Scale Contrast and Short Scale Contrast

Short-scale contrast describes a radiograph in which the density differences between adjacent areas are large. … Long-scale contrast describes a radiograph in which the density differences between adjacent areas are large. Increasing the kVP results in a more penetrating x-ray beam.

What is the difference between long scale and short scale contrast?

In the long scale image, you can see many more subtle steps. In the image of the elbow, the contrast is relatively high so this can be called short scale contrast. One problem with short scale contrast is the fact that subtle details can be missed or not imaged.

What is short scale contrast radiography?

Short-scale contrast Short-scale radiographs are considered ‘high-contrast’ whereby density differences albeit greater, overall possess fewer in density steps (lesser shades of grey).
