Plain radiography

B.

Fluoroscopy

C.

Mammography

D.

Magnetic resonance imaging (MRI)

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is D

Explanation

When performing X-ray imaging on a pediatric patient with suspected scoliosis, using gonad shields is essential to protect the child's reproductive organs from unnecessary radiation exposure.

a. Performing X-rays at a higher resolution may provide better visualization of the spine, but it is not directly related to the safety measure required for a pediatric patient with suspected scoliosis.

b. Applying lead aprons to protect the child's abdomen and chest only does not adequately protect the reproductive organs. Gonad shields are specifically designed for this purpose.

c. While limiting the number of X-ray images taken is a good practice to minimize radiation exposure, it may not be feasible for diagnostic purposes in cases of suspected scoliosis that require multiple images for evaluation and treatment planning.

Correct Answer is B

Explanation

For an X-ray of the chest, the patient should wear loose-fitting clothing that does not contain any metal, such as zippers, buttons, or jewelry, to avoid interference with the X-ray image and ensure optimal visualization of the chest.

a. Refraining from eating or drinking for 24 hours before the procedure is not necessary for a chest X-ray, as it is a non-invasive procedure that does not require fasting.

c. While it is essential for the patient to lie still during the X-ray, this instruction is not specific to a chest X-ray; it applies to all X-ray procedures to prevent motion artifacts.

d. Emptying the bladder is not required for a chest X-ray, as the bladder is not in the field of view for this particular imaging procedure.
