Using AI for Attenuation Correction in PET Imaging
Researchers from the National Cancer Institute have proposed an AI tool to generate attenuation-corrected PET images directly from non-attenuation-corrected PET scans, reducing the reliance on CT scans. The deep learning algorithm, based on a GAN architecture, was trained using paired AC-PET and NAC-PET images from prostate cancer patients. The AI model effectively bypasses the need for low-dose CT scans during PET-CT studies, demonstrating promising results in terms of image quality and accuracy.
