Radiologic Technologist Practice Exam

Which of the following image artifacts will appear as an area of increased brightness?

1. 1 and 2

2. 1 and 3

3. 2 and 3

4. 1, 2, and 3

The correct answer is: 1, 2, and 3

The correct choice indicates that all the artifacts referenced in the question will appear as areas of increased brightness on a radiographic image. Image artifacts can be caused by various factors, leading to variations in the final image quality observed. Increased brightness generally occurs due to the presence of excessive radiolucency or excessive exposure in the areas concerned. Artifacts contributing to this phenomenon may include factors such as a foreign object within the imaging field, the presence of air or gas in the area imaged, or construction artifacts from the imaging system itself. Each of these types can lead to an erroneous bright appearance in specific areas of the radiograph. Understanding these radiographic principles is essential for technologists, as recognizing and correcting for such artifacts is crucial in ensuring accurate diagnosis and patient care. This knowledge also builds a foundation for troubleshooting imaging challenges which may arise during routine practice.
