Posted on: 04/25/2014. CT scans and MRI scans both provide diagnostic images of the inside of your body. However, they accomplish this important task in very different ways. Here are a few key differences between CT scans and MRI scans.

There is no radiation hazard risk for the patients undergoing an MRI scan. A PET scan, on the other hand, is a procedure with a certain level of radiation involved. The levels of radiation received by patients during a PET scan are comparable with the level of radiation received during a X-ray procedure.

Difference between MRI and PET scan. Published on September 28, 2015. MRI, or magnetic resonance imaging, and PET, or positron emission tomography, are techniques that are designed to create images of what is going on inside the human organism.

Advantages of PET vs. CT scan. CT scans have advantages in viewing anatomical structures. Due to the high contrast resolution of CT scanning, differences between the tissues are more apparent compared to other techniques. Further, imaging in CT scan removes the superimposition of structures other than the area of interest.

1 A PET scan, on the other hand, is a procedure with a certain level of radiation involved. The levels of radiation received by patients during a PET scan are comparable with the level of radiation received during a X-ray procedure.  The price of an MRI scanning procedure varies from $1000 to $4000.

MRI scans do not work this way. Instead of using ionizing radiation, magnetic resonance imaging (MRI) uses radio waves and powerful magnets to produce diagnostic images. An MRI scanner can apply a magnetic field that lines up all of your body’s protons.

Difference between MRI and PET scan. MRI, or magnetic resonance imaging, and PET, or positron emission tomography, are techniques that are designed to create images of what is going on inside the human organism. PET works via detecting emitted gamma rays, while MRI utilizes magnetic waves and radio waves to produce images.

Principle and Procedure. A CT scan relies on a series of X-rays and is usually completed within 5-10 minutes. On the other hand, a PET scan takes anywhere between 2 to 4 hours. The basic principle behind a CT scan relies on the reconstruction of a three dimensional image of an organ, by a computer.

CT Scan vs. PET Scan. CT scan (computer tomography) and PET scan (positron emission tomography) are different but related imaging techniques. A PET scan uses nuclear medicine imaging to produce a three-dimensional picture of functional processes in the body.

CT scans typically take diagnostic images more quickly than MRI scans. For example, a CT scan can often be completed in less than 5 minutes while MRIs take an average of 30 minutes.

A positron emission tomography scan involves a risk of radiation while an MRI scan doesn't involve any radiation hazard risk.
