What is the effect of incorrect kVp settings on radiographic imaging?

Incorrect kVp settings can significantly impact both the quality of the radiographic image and the amount of radiation exposure to the patient.

When the kilovolt peak (kVp) is set too low, it results in insufficient energy to penetrate dense tissues, leading to images that are overly dark or exhibit increased contrast. This can result in a lower clarity of images, making it difficult to differentiate between anatomical structures. Inadequate penetration means that some details may be obscured, ultimately affecting the diagnostic quality of the radiograph.

On the other hand, if the kVp is set too high, it can lead to excessive radiation being delivered to the patient since higher energy levels increase the likelihood of radiation interaction with the patient's body. This not only exposes the patient to unnecessary radiation but can also produce images that are too light or have reduced contrast, resulting in a loss of important diagnostic information.

Thus, incorrect kVp settings can indeed lead to both increased patient radiation exposure and lower clarity of images, making the option that includes both effects the accurate choice.
