Here are the main differences between an MRI, an MRA, a CT SCAN, a PET SCAN & an X-RAY:
MRI: Magnetic Resonance Imaging is a medical imaging technique that uses strong magnetic fields, radio waves, and computer technology to produce detailed images of the internal structures of the body. It is particularly useful for imaging soft tissues, such as organs, tendons, and ligaments, which are not visible on X-rays. It's commonly used to diagnose conditions such as joint and musculoskeletal disorders, certain types of cancer, and neurological disorders.
MRA: Magnetic Resonance Angiogram is a non-invasive MRI scan that examines the body's blood vessels. It uses radio waves and a magnetic field to create images of blood flow and blood vessel walls.
CT: Computed Tomography scan is a medical imaging test that uses X-rays and computer algorithms in order to produce detailed images of the inside of the body. It's commonly used to diagnose injuries or abnormalities in organs, bones and soft tissues. It also detects and monitors diseases, such as cancer, vascular diseases, and internal injuries while monitoring the effectiveness of treatments.
PET: Positron Emission Tomography scan is a type of medical imaging test that helps visualize the metabolic activity within the body.
It uses a radioactive tracer (usually a sugar molecule) that's injected into the body.
This tracer accumulates in areas with high metabolic activity, such as cancer cells.
X-RAY: Known as a Radiograph, which is a type of radiation called electromagnetic waves. It uses invisible beams to produce images of internal tissues, bones, and organs on film or digital media. It is performed for many reasons, including diagnosing tumors or bone fractures/injuries.
