One challenging case involved a patient with severe claustrophobia. To manage this, I reassured the patient throughout the procedure, explaining each step and allowing frequent breaks. I also adjusted the equipment settings to minimize the scanner's noise, creating a more comfortable environment. By maintaining clear communication and empathy, I was able to complete the scan without compromising the quality of the images.

Patient safety is paramount. I ensure thorough pre-scan checks of all equipment and follow strict radiation safety protocols. I also educate patients on the potential risks and benefits, ensuring they understand the procedure. During the scan, I monitor the patient continuously, ready to intervene if any issues arise. Post-scan, I ensure proper disposal of radioactive materials and follow up with the patient to address any concerns.

Maintaining image quality involves regular calibration of the scanner, using optimal imaging protocols, and ensuring patients follow preparation guidelines. I also conduct daily quality control checks and participate in continuous education to stay updated on the latest techniques. By meticulously following these practices, I ensure that the images are of high quality, aiding in accurate diagnosis and treatment planning.

In such situations, I first try to understand the reasons behind the non-compliance. I then provide clear, concise explanations of why the instructions are crucial for accurate results. If necessary, I collaborate with the patient's healthcare team to address any concerns or misunderstandings. By fostering a supportive and understanding environment, I aim to ensure patient cooperation and successful scan outcomes.

I have worked with various PET/CT scanner models, including the GE Discovery and Siemens Biograph. Each model has unique features, such as advanced motion correction technology or higher resolution imaging. I am adept at navigating their interfaces and optimizing settings for different patient needs. My experience allows me to adapt quickly to new models and leverage their features to enhance diagnostic accuracy.
