I understand the importance of radiation safety and consistently practice it in my daily work.

7. Describe your experience with different types of CT contrast media.

   • Answer: I have experience administering and managing various types of CT contrast media, including both iodinated and non-iodinated agents. I am proficient in assessing patient allergies and contraindications before administering contrast, and I am familiar with the potential side effects and how to manage them. I also understand the importance of proper contrast media handling and disposal.

8. How do you identify and troubleshoot common CT scanner malfunctions?

   • Answer: I am adept at identifying and troubleshooting common CT scanner malfunctions, such as image artifacts, system errors, and mechanical issues. My approach involves systematically checking the scanner's parameters, reviewing error logs, performing basic troubleshooting steps, and escalating complex issues to biomedical engineers. I am familiar with the scanner's diagnostic codes and can quickly identify the source of the problem to minimize downtime.

9. How do you ensure the quality of CT images?

   • Answer: I ensure the quality of CT images through meticulous attention to detail in every step of the process. This begins with appropriate patient preparation and positioning, careful selection of scan parameters, and monitoring image acquisition for any artifacts. Post-acquisition, I review the images for quality and make adjustments as needed before sending them to the radiologist. Regular quality control checks on the equipment are also crucial.

10. Explain your understanding of different CT scan protocols.

    • Answer: I am familiar with a wide range of CT scan protocols for various anatomical regions and clinical indications, including head, neck, chest, abdomen, pelvis, and extremities. I understand the specific parameters and techniques required for each protocol, including contrast administration where appropriate. I can adapt protocols based on the patient's specific needs and the radiologist's orders.

11. How do you handle an emergency situation during a CT scan?

    • Answer: In an emergency situation, I would immediately stop the scan, assess the patient's condition, and provide appropriate first aid or basic life support (BLS) as trained. I would then alert the appropriate medical personnel, such as the emergency response team or physician, and follow their instructions. Maintaining patient safety and providing timely assistance is my highest priority.

12. What is your experience with PACS (Picture Archiving and Communication System)?

    • Answer: I have extensive experience working with PACS systems. I am proficient in accessing, reviewing, and managing CT images within the PACS system. I understand the workflow associated with image routing, storage, retrieval, and distribution to radiologists and other healthcare professionals.

13. Describe your experience with post-processing techniques for CT images.

    • Answer: I am familiar with various post-processing techniques used to enhance CT images, such as multiplanar reconstruction (MPR), volume rendering, and maximum intensity projection (MIP). I understand how these techniques can aid in the diagnosis and assessment of various pathologies. My experience includes using dedicated software for these post-processing tasks.

14. How do you maintain accurate and up-to-date patient records?

    • Answer: I maintain accurate and up-to-date patient records by meticulously documenting all aspects of the CT scan procedure, including patient demographics, medical history (as relevant), scan parameters, contrast administration details, and any unusual occurrences. I ensure all information is entered correctly into the electronic health record (EHR) system and adhere to strict confidentiality protocols.

15. How do you handle difficult or challenging patients?

    • Answer: I approach each patient with empathy and understanding. Even with challenging patients, I maintain a calm and professional demeanor, communicating clearly and patiently.
