Which type of X-ray imaging is commonly used for evaluating the digestive system and the movement of contrast agents in real-time?

Fluoroscopy is a type of X-ray imaging that provides real-time moving images of blood vessels and organs in the body. It is commonly used for procedures such as angiography and barium studies.

a. Plain radiography, also known as X-ray radiography, is used to visualize bones and some soft tissues but does not provide real-time moving images like fluoroscopy.

c. Mammography is a specialized type of X-ray imaging used for breast examination, primarily for detecting breast cancer.

d. Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create detailed images of organs and tissues, but it does not use X-rays for imaging.

Requesting others in the room to wear protective lead aprons is an effective way to reduce radiation exposure to other patients and staff in the vicinity of the X-ray procedure.

a. Keeping the X-ray room door open during the procedure can lead to increased radiation exposure to people outside the room. The door should be closed during X-ray imaging to minimize radiation scatter.

b. Placing the X-ray machine at a higher elevation does not affect radiation exposure to other patients and staff in the room. The proper use of protective lead aprons is more effective.

d. Increasing the number of X-ray images taken at one time does not reduce radiation exposure to others in the room. The number of images taken should be limited to those necessary for diagnostic purposes while minimizing radiation dose to all individuals present.
