Radiographic Seminar Exam 2 Practice

Short scale radiography yields which level of contrast?

High contrast Low contrast Moderate contrast No contrast

Correct Answer:

High contrast

Explanation:

Short scale radiography yields high contrast. Contrast is the difference in density seen on the image between adjacent tissues. When the scale is short, there are only a few gray tones, so differences between structures are stark. This happens with lower kVp and high subject contrast, where dense tissues like bone attenuate the beam far more than soft tissue, making bone appear very white against a darker background and soft tissues appear in limited gray shades. If you raise kVp, the image has more gray levels and lower contrast—longer scale.
