CT scan vs. CAT scan: What’s the difference? A CT scan and a CAT scan are the same thing.
CT stands for computerized tomography and CAT stands for computerized axial tomography.
By my definition, Preventive medicine is focused on diet and exercise and supplements and colonoscopies. By contrast, Predictive medicine is focused on an annual, non-invasive search of all the systems of your body so that doctors might identify life-threatening developments while they are still easily treatable. Your insurance company is unlikely to pay for a full-body scan if you have no symptoms, but if a problem is found by the doctor who performed your scan, your insurance company is required to pay for treatment of whatever problem was discovered. – Indy Beagle
