How does patient motion affect PET/CT image quality?

• A. It has no significant effect
• B. It can enhance the image clarity
• C. It can lead to blurring and artifacts
• D. It makes the images more detailed

Answer: (C)

Patient motion can significantly degrade the quality of PET/CT images, and the correct response highlights this impact by indicating that it can lead to blurring and artifacts. When a patient moves during the imaging process, the resulting images may not accurately represent the location of radiotracers that have been injected into the body. Instead of a clear and precise representation of metabolic activity and anatomical structures, motion can cause smearing, misregistration of the image data, and the introduction of artifacts that compromise diagnostic accuracy. Blurring occurs because the position of the radiotracer changes while the camera is capturing the data, leading to a loss of spatial resolution. Artifacts can mislead practitioners into interpreting areas as abnormal when they are simply the result of motion, which can influence clinical decisions and patient management. Thus, minimizing motion during PET/CT scans is critical for achieving high-quality imaging, which is essential for accurate diagnosis and treatment planning.
