CT: Computerized tomography scans utilize multiple x-rays taken at different angles. They feed this large amount of information into a computer program that uses an algorithm to create a large three dimensional picture of the internal anatomy of an object. This includes hard and soft tissues.
PET: Positron Emission Tomography scans are used in conjunction with MRI or CT scans. This machine measures the positron emissions from common elements like carbon, nitrogen and oxygen. This scan shows molecular functions in tissue. This helps to detect and identify the size of tumors, cancer, and dead or diseased tissue.
MRI: Magnetic resonance technology was introduced in the 1980’s. This scan provides structural information about the internal anatomy. It utilizes super cooled magnets to produce images by measuring the magnetism of electrons and protons. It is particularly useful for identifying diseased and damaged tissues.
