Which imaging procedure does NOT include ultrasound?

The imaging procedure that does not include ultrasound is computed tomography (CT). CT scans utilize X-ray technology to create detailed cross-sectional images of the body, allowing for the visualization of internal structures. The process involves rotating an X-ray tube around the patient and capturing multiple images, which are then compiled by a computer to produce comprehensive images.

In contrast, ultrasound employs high-frequency sound waves to create images of structures within the body, which means it relies on a completely different mechanism than CT. Similarly, magnetic resonance imaging (MRI) uses strong magnetic fields and radio waves, while fluoroscopy combines X-ray imaging with a fluorescent screen to obtain real-time images of moving structures within the body, neither of which involve the ultrasound technique. Plain radiology, or traditional X-rays, also does not involve ultrasound technology. Thus, the correct identification of CT as not incorporating ultrasound is valid.
