Which of the following is used for a chest x-ray?

A CT scan, or computed tomography scan, provides detailed cross-sectional images of the body using X-rays and computer processing. While it can offer more detailed information than a standard chest x-ray, it is not the primary method for initial chest imaging and involves higher radiation exposure and more complex procedures.

Angiography is a specialized imaging technique used to visualize the inside of blood vessels and organs, primarily to detect blockages or abnormalities in the vascular system. It is not used for chest x-rays, as its focus is on blood vessels rather than the structures visible in a standard chest x-ray.

Fluoroscopy is a technique that uses continuous X-ray imaging to create real-time video of the body’s movements. While it can be useful for observing dynamic processes, such as swallowing or the motion of joints, it is not employed for the static imaging required in chest x-rays.
