A full-body PET Scan is the most trending preventive diagnostic tool that apparently tells you what is happening in your body from brain to toe and aids in detecting diseases like cancer when it is still curable. Of all the internal imaging technologies used in getting a full-body scan, PET Scans are the most detailed one.
