Fluoroscopy - Clinical Science Questions and Answers
This set of Clinical Science Multiple Choice Questions & Answers (MCQs) focuses on “Fluoroscopy”.
Answer: a
Explanation: Fluoroscopy is a process that depends upon the radioactivity of the dye to show the image. When the dye is
injected or ingested, it emits radioactive waves which are captured/recorded using devices. Thus, for fluoroscopy, dye is a
necessity.
Answer: b
Explanation: When we swallow something, it always goes to the Gastrointestinal Tract. Radioactive barium in trace amounts
is swallowed and the projected X-Ray beams photograph/record/project the whole process. The GI tract lights up and the
examiner can see inside the track.
3. Which another method can be used to look in the compete for GI tract?
a) Endoscopy
b) Capsule Endoscopy
c) Colonoscopy
d) Laryngoscopy
View Answer
Answer: b
Explanation: Capsule Endoscopy can help look into the whole of the GI tract. The capsule has a miniature camera. The
capsule is swallowed and as it moves down the track, it images the track. The images are either transmitted or stored and
later recovered.
4. The following machine, along with fluoroscopy process is also used for minimal invasive surgery. Which machine is it?
Answer: c
Explanation: C – Arm is used for diagnosis and minimally invasive procedures. The two plates at the end of the two arms
have receiving and transmitting ends for X – Rays. The C – Arm can also rotate and move at various degrees thus providing
access and visuals from many directions and angles.
5. Which of the following agents should not be used as an agent for fluoroscopy?
a) Silver
b) Bismuth
c) Thoria
d) Tungsten
View Answer
Answer: c
Explanation: Thoria stands for thorium dioxide. It was found to cause liver cancer so the use of thoria as an agent for
fluoroscopy was discontinued. All the other three materials are still used for fluoroscopy but the dyes most preferred are
made from iodine.

Answer: d
Explanation: All of the above mentioned processes require some sort of placement. Often some of these surgeries are
minimally invasive so to visualize what is going inside the body, fluoroscopic dyes are used to keep monitoring them.
Sometimes, after a surgery, to ensure that the wound is healing well or that the placements are in proper places, fluoroscopy
can be used.
7. If a PET scan is being used to detect tumors, an important constituent of the injected radioligand will be _____
a) glucose
b) lipids
c) keratin
d) riboflavin
View Answer
Answer: a
Explanation: For any growing or recovering part of the body, the most important content is carbohydrate which is provided
by glucose. Thus, to test for a suspected malignant tumour, a glucose based radioligand is used. This radioligand is absorbed
by a tumour and it collects and becomes part of the normal functioning of the body. The more the collection of the
radioligand at one place, greater is the size or the activity of a tumour.
8. Bone Scintigraphy done with the help of Tc-99m with methylene diphosphonate (MDP) is an example of ________
a) PET
b) SPECT
c) CT
d) MRI
View Answer
Answer: b
Explanation: SPECT uses Tc – 99m in its dyes. Bone Scintigraphy is a process in which the dye is injected and the bones are
imaged. It can help look for cancer, inflammation, fractures etc. Since it can image with respect to time, it can also help plot
out the metabolism of the bone.
