An MRI scan can be used when your organ shape or blood vessels are in question, whereas PET scans will be used to see your body’s function. What is an MRI? MRI exams use magnetic fields and...
A PET scan is used to diagnose cancer, heart disease, and some brain disorders. It supplies information that’s different from an MRI or CT scan. While a CT and MRI scan looks at the “form” of structures inside your body, a PET scan looks at their function and shows unusual cellular activity.
assess brain damage or disorders such as tumors, seizures, or cognitive issues, evaluate damage to the heart following a heart attack, or. assess the state of coronary artery disease. In many cases, a PET scan is used in conjunction with an MRI scan.
A brain positron emission tomography (PET) scan is an imaging test that allows doctors to see how your brain is functioning. The test accurately details the size, shape, and function of...
A neurologist breaks down when they would order a computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) scan to take images of the body.
In this article, we will explore the key differences between MRI (Magnetic Resonance Imaging) and PET (Positron Emission Tomography) scans. We’ll discuss their underlying technologies, imaging capabilities, and specific applications.
Computed tomography (CT) scans use X-rays. Magnetic resonance imaging (MRI) scans use magnets and radio waves. Both produce still images of organs and body structures. PET scans use a radioactive tracer to show how an organ is functioning in real time.
