Researchers have developed a new method called Lesion-Aware Adaptive Fourier Neural Operator (LAFNO) to improve the synthesis of PSMA PET images from CT scans for prostate cancer patients. Traditional deep learning models often use global losses that can lead to underestimation of tumor activity. LAFNO addresses this by incorporating lesion-specific proxy channels derived from CT scans, focusing on local density variation and texture heterogeneity. This approach enhances the accuracy of total lesion activity (TLA) and tumor-core contrast while maintaining competitive whole-volume image quality. AI
IMPACT This research could lead to more accurate and less invasive diagnostic imaging for prostate cancer patients by improving AI-driven synthesis of PET scans from CT data.
