What is the difference between a CT scan and an MRI scan?

Both types of scan have similar uses, but they produce images in different ways. A CT scan uses X-rays, whereas an MRI scan uses strong magnetic fields and radio waves. CT scans are more common and less expensive, but MRI scans produce more detailed images.

Is there any preparation before an MRI?

Before an MRI exam, eat normally and continue to take your usual medications, unless otherwise instructed. You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as: Jewelry. Hairpins.

Why do I need both MRI and CT scan?

Radiologists use both CT and MRI to detect and monitor cancer. Each imaging method has strengths that make it appropriate for a particular reason. Learn how doctors choose which technique to use. CT (computed tomography) and MRI (magnetic resonance imaging) are both used to diagnose and stage cancer.

What is the difference between CT scan and MRI scan?

The MRI machine is similar to the CT machine in external appearance. However the mechanism is totally different. MRI scan gives better images than CT about the soft tissues. Brain and spinal cord images are better with MRI scan. MRI scan can be used in pregnancy as this is safe.

Why do doctors use CT scans and MRIs?

Our doctors use advanced imaging tests, such as CT scans, MRIs, and PET scans, to help detect and diagnose disease, make appropriate treatment recommendations, and monitor your response to therapy. What concerns do people have about either imaging method?

Do you get an MRI or CT scan first for cancer?

We usually use CT first for most people, unless a tumor is much better seen on MRI. But we go back and forth as needed. If we see something on a CT scan we’re unsure about, we may recommend an MRI for further evaluation.

What is an MRI scan?

MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation.
