Fig. 7From: A deep learning approach for 18F-FDG PET attenuation correctionPET reconstruction using a deepAC and b acquired CT-based attenuation correction (CTAC) for a 59-year-old male with a brain tumor. The tumor region was indicated by a red arrow in CTAC PET image. Low reconstructed PET error is observed by using the proposed deepAC approach given the presence of brain metastasisBack to article page
