100 Angiography Technologist Interview Questions and Answers

  1. What is angiography?

    • Answer: Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs of the body, with a particular focus on the arteries, veins, and heart. It involves injecting a contrast medium into the bloodstream and using X-rays to create images.

  2. Describe your experience with different types of angiography procedures.

    • Answer: (This answer will vary depending on the candidate's experience. A good answer would list specific procedures like coronary angiography, peripheral angiography, cerebral angiography, and potentially others, detailing their involvement in each.) For example: "I have extensive experience in coronary angiography, assisting physicians with catheterization and image acquisition. I'm also proficient in peripheral angiography, particularly in the lower extremities, and have assisted in several cerebral angiographies."

  3. Explain the role of contrast media in angiography.

    • Answer: Contrast media are iodine-based solutions injected into the bloodstream. They temporarily increase the radiopacity of the blood vessels, making them clearly visible on X-ray images. This allows the physician to visualize the blood flow and identify any blockages or abnormalities.

  4. What are the potential risks and complications associated with angiography?

    • Answer: Potential risks include bleeding at the puncture site, allergic reactions to the contrast media (ranging from mild hives to anaphylaxis), infection, hematoma formation, kidney damage (especially in patients with pre-existing kidney disease), stroke (in cerebral angiography), and perforation of a blood vessel.

  5. How do you prepare a patient for an angiography procedure?

    • Answer: Patient preparation includes obtaining informed consent, reviewing the patient's medical history and medication list (especially anticoagulants), assessing for allergies, ensuring NPO status (nothing by mouth) for a specified period, placing an IV line, monitoring vital signs, explaining the procedure, and answering any questions the patient may have. Pre-procedure medication may also be administered as directed by the physician.

  6. Describe the equipment used in an angiography suite.

    • Answer: Angiography suites typically include an X-ray machine (fluoroscopy unit), image intensifier, digital subtraction angiography (DSA) system, hemodynamic monitoring equipment (blood pressure, ECG), injection system for contrast media, catheters of various sizes and shapes, guidewires, various other interventional tools, and sterile supplies.

  7. Explain the process of image acquisition during angiography.

    • Answer: Image acquisition involves injecting the contrast media and using the fluoroscopy unit to obtain real-time X-ray images. The DSA system digitally subtracts background images to enhance the visualization of the blood vessels. The technologist manipulates the X-ray beam and image intensifier to obtain optimal images, taking care to minimize radiation exposure to both the patient and staff.

  8. How do you ensure radiation safety during angiography procedures?

    • Answer: Radiation safety is paramount. We use lead shielding (aprons, gowns, thyroid shields) to protect ourselves and the patient. We use the ALARA principle (As Low As Reasonably Achievable) by minimizing fluoroscopy time, optimizing the image acquisition parameters, and using pulsed fluoroscopy when possible. We also adhere to strict radiation safety protocols and maintain accurate radiation exposure records.

  9. What is the role of the angiography technologist during a procedure?

    • Answer: The angiography technologist plays a crucial role in preparing the patient, setting up the equipment, assisting the physician during the procedure (including catheterization, contrast injection, and image acquisition), monitoring the patient's vital signs, maintaining a sterile field, and ensuring the safety of both the patient and the staff. Post-procedure care, such as applying pressure to the puncture site and monitoring for complications, is also part of the role.
