Question

Match the special diagnostic techniques with their correct definitions.

-Radiopaque substances are given and x-rays taken

Quizplus · Accepted Answer

Contrast studies involve the use of a radiopaque substance, such as iodine or barium, which is given to the patient and then imaged using x-rays or other modalities.

Answer: B
 Computed tomography (CT) involves taking x-rays of the body from multiple angles and then using a computer to reconstruct detailed cross-sectional images.

Answer: G
 Positron emission tomography (PET) involves injecting a small amount of radioactive material into the body, which is then imaged using a special camera that detects the radiation emitted by the material.

Answer: E
 Interventional radiology involves using imaging techniques to guide minimally invasive procedures, such as biopsies or the placement of catheters and stents.

Note: The other techniques listed (nuclear medicine, lymphoscintigraphy, ultrasonography, magnetic resonance imaging) do not involve the use of radiopaque substances and are therefore not matched with the given definition.
