What is the primary purpose of fluoroscopy?

  1. To capture still images of internal organs and structures

  2. To perform minimally invasive procedures under real-time X-ray guidance

  3. To detect and diagnose bone fractures and injuries

  4. To measure the density of tissues and organs


Correct Option: B
Explanation:

Fluoroscopy is primarily used to provide real-time X-ray images during medical procedures, allowing physicians to visualize internal organs and structures in motion.

Which type of radiation is utilized in fluoroscopy?

  1. Ultrasound waves

  2. Magnetic fields

  3. X-rays

  4. Radio waves


Correct Option: C
Explanation:

Fluoroscopy utilizes X-rays to generate real-time images of internal structures.

What is the main advantage of fluoroscopy over conventional X-ray imaging?

  1. It provides higher resolution images

  2. It can capture images of moving structures in real-time

  3. It requires less radiation exposure

  4. It is less expensive


Correct Option: B
Explanation:

Fluoroscopy's primary advantage is its ability to provide real-time imaging, allowing physicians to observe dynamic processes and movements of internal organs and structures.

What is the term used to describe the continuous X-ray beam emitted during fluoroscopy?

  1. Pulsed beam

  2. Continuous beam

  3. Intermittent beam

  4. Modulated beam


Correct Option: B
Explanation:

Fluoroscopy involves the use of a continuous X-ray beam to generate real-time images.

What is the primary component of a fluoroscopy system?

  1. X-ray tube

  2. Image intensifier

  3. Fluorescent screen

  4. Computer monitor


Correct Option: B
Explanation:

The image intensifier is the core component of a fluoroscopy system, converting X-rays into visible light, allowing real-time imaging.

What is the role of the fluorescent screen in fluoroscopy?

  1. It converts X-rays into visible light

  2. It amplifies the X-ray signal

  3. It displays the real-time images

  4. It controls the X-ray beam


Correct Option: C
Explanation:

The fluorescent screen in fluoroscopy displays the real-time X-ray images generated by the image intensifier.

What is the purpose of the collimator in fluoroscopy?

  1. To focus the X-ray beam

  2. To limit the area of X-ray exposure

  3. To adjust the brightness of the images

  4. To control the X-ray pulse rate


Correct Option: B
Explanation:

The collimator in fluoroscopy is used to limit the area of X-ray exposure, reducing unnecessary radiation scatter and minimizing patient exposure.

What is the typical radiation dose associated with a fluoroscopy procedure?

  1. Less than 1 mSv

  2. 1-10 mSv

  3. 10-100 mSv

  4. More than 100 mSv


Correct Option: B
Explanation:

The typical radiation dose associated with a fluoroscopy procedure ranges from 1 to 10 mSv, depending on the duration and complexity of the procedure.

What is the primary concern regarding radiation exposure in fluoroscopy?

  1. Long-term health effects

  2. Immediate skin reactions

  3. Eye damage

  4. Nausea and vomiting


Correct Option: A
Explanation:

The primary concern regarding radiation exposure in fluoroscopy is the potential for long-term health effects, including an increased risk of cancer.

What is the recommended method to minimize radiation exposure during fluoroscopy?

  1. Using lead aprons and shields

  2. Limiting the duration of the procedure

  3. Using pulsed X-ray beams

  4. All of the above


Correct Option: D
Explanation:

To minimize radiation exposure during fluoroscopy, it is recommended to use lead aprons and shields, limit the duration of the procedure, and utilize pulsed X-ray beams.

What is the typical application of fluoroscopy in medical procedures?

  1. Barium swallow studies

  2. Cardiac catheterization

  3. Endoscopic procedures

  4. All of the above


Correct Option: D
Explanation:

Fluoroscopy is commonly used in medical procedures such as barium swallow studies, cardiac catheterization, and endoscopic procedures, providing real-time X-ray guidance.

What is the role of the fluoroscopist in a fluoroscopy procedure?

  1. Operating the fluoroscopy equipment

  2. Interpreting the X-ray images

  3. Administering contrast agents

  4. All of the above


Correct Option: D
Explanation:

The fluoroscopist is responsible for operating the fluoroscopy equipment, interpreting the X-ray images, administering contrast agents, and ensuring the safety of the patient during the procedure.

What is the term used to describe the temporary cessation of X-ray exposure during fluoroscopy?

  1. Fluoroscopic pause

  2. X-ray blackout

  3. Beam interruption

  4. Image hold


Correct Option: A
Explanation:

Fluoroscopic pause refers to the temporary cessation of X-ray exposure during fluoroscopy, allowing the physician to review the captured images.

What is the recommended frequency for quality assurance checks on fluoroscopy equipment?

  1. Annually

  2. Semi-annually

  3. Quarterly

  4. Monthly


Correct Option: D
Explanation:

Quality assurance checks on fluoroscopy equipment are typically recommended to be performed monthly to ensure optimal image quality and safety.

What is the primary limitation of fluoroscopy?

  1. High radiation exposure

  2. Poor image quality

  3. Limited field of view

  4. All of the above


Correct Option: A
Explanation:

The primary limitation of fluoroscopy is the potential for high radiation exposure to the patient and healthcare providers.
