One challenging procedure involved a patient with severe claustrophobia. I ensured the patient was comfortable by explaining each step, allowing frequent breaks, and using relaxation techniques. By maintaining clear communication and empathy, the patient felt reassured and we successfully completed the scan without complications.

Patient safety is paramount. I verify no metal objects are present, review patient history for contraindications, and explain the procedure thoroughly. During the scan, I monitor the patient's condition via intercom and have emergency protocols ready. Ensuring the MRI environment is safe and the patient is informed minimizes risks.

Quality control starts with regular equipment calibration. I also follow strict protocols for patient positioning and use advanced imaging techniques. Regular training on new technologies and staying updated with best practices ensures high-quality images, which are crucial for accurate diagnoses.

In such cases, I first try to calm the patient by explaining the importance of stillness and offering reassurance. If necessary, I might use sedation under medical supervision. Additionally, I ensure the patient understands the procedure to reduce anxiety, which often helps in maintaining stillness.

I have worked with various MRI scanners, including 1.5T and 3T machines. Each has unique features like higher resolution and faster imaging times. Understanding these differences allows me to optimize patient care and image quality, adapting my techniques to the specific capabilities of each scanner.
