PET scan is an imaging test that allows your doctor to check for diseases in your body. MRI scan This technology uses radioactive positrons (positively charged particles) to detect differences in metabolic and chemical activity in the body. CT scan uses a special digital x-ray detectors, which are located directly opposite the x-ray source.

MRI costs range from $1200 to $4000  (with contrast);which is usually more than CT scans and X-rays, and most examining methods. CT scan costs range from$1,200 to $3,200 they usually cost less than MRIs (about half the price of MRI ). PET scans cost $3,000 to $6,000 much higher than regular CT scans.

CT stands for computed or computerized tomography. This is essentially a series of X-rays in "slices" through the body, which are then analyzed by a computer, and an image constructed from the data.
MRI scans use magnets rather than X-rays to produce the image.This technology uses radioactive positrons (positively charged particles) to detect differences in metabolic and chemical activity in the body. An area with increased activity will show on a colored image.

ct scan or magnetic resonance  (MRI)uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body. PET scan reveals the cellular level metabolic changes occurring in an organ or tissue.
