Radiology Practice Test

Blurred radiographs may result from?

1. The spreading of microorganisms from one person to another.

2. Interproximal/BWX

3. Movement during exposure

4. Orthodontics

The correct answer is: Movement during exposure

Blurred radiographs can occur from movement during exposure. The blurring originates from movement during the x-ray procedure and therefore the result produced may be hard to read. Using a radiographic stabilization device or instructing the patient to stay still can help prevent this issue. The other options, A, B, and D, are incorrect because they do not directly relate to the cause of blurred radiographs. Option A mentions the spreading of microorganisms, which can cause infections but does not affect the quality of a radiograph. Option B refers to specific types of radiographs, which do not necessarily cause blurring. Option D mentions orthodontics, which involves the movement of teeth, but not during the exposure of a radiograph.
