Do you know the difference between a PET scan and an MRI? We explain the primary difference between the two diagnostic tools. Learn what that difference means.
What’s the difference between a PET scan, CT scan and MRI? 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.
Learn how MRI and PET scans work, what they can reveal, and how they differ in terms of time, radiation, and cost. Find out when to choose each scan for cancer diagnosis and monitoring.
Compared with an X-ray or magnetic resonance imaging (MRI) scan, a PET/CT enables doctors to examine medical conditions and abnormalities at a cellular level. PET scan vs. CT scan Whereas CT scans take pictures from a variety of angles to show images of the patient's body organs, tissues and bones, the PET scan shows how the patient's cells ...
A PET scan can help reveal the metabolic or biochemical function of your tissues and organs, and detect the atypical metabolism of cancer cells. Learn how to prepare, what to expect and how to interpret the results of a PET scan, and how it can be combined with CT or MRI scans.
Learn how PET scans and MRIs differ in their purposes, procedures, and costs. PET scans show cellular-level functions, while MRIs show organ structures. Both can detect and track cancer and other conditions.
Learn the differences and benefits of MRI, CT, and PET scans, three advanced imaging technologies that provide detailed views of your body. Find out what each scan shows, how to prepare, and when to choose one over the other.
Learn how CT, MRI and PET scans use different methods and technologies to produce images of your body. A CT scan shows the shape of organs and structures, an MRI scan shows their function, and a PET scan detects metabolic activity.
Learn how PET and MRI scans work, what they can show, and when they are used for different medical conditions. Compare the pros and cons of each scan, including radiation exposure, contrast, and cost.
Improved safety from significantly reduced radiation exposure: Compared to PET/CT scans, PET/MRI exposes patients to about 50% less radiation. Convenience of two scans in one: PET/MRI eliminates the need for separate appointments.
