PAIRE is a software as a medical device for PET-CT examination with FDG, highlighting lesions on the PET scan. It receives DICOM images from the PET-CT modality and computes new images. Then, it returns them into the physician viewer as new images for the same study. It is fully integrated, vendor neutral, available in less than 5 minutes and requires no action from the radiologist. Its aim is to save time and improve the diagnosis with new information.
