This article will discuss the 1.5T, 2T and 3T MRI, and its uses. We will also discuss some common questions about 3T MRI.
MRI (Magnetic Resonance Imaging) is the radiological diagnostic tool for the diagnosis of abnormalities. MRI produces images of the internal body and blood vessels for the diagnosis of abnormalities in the body. MRI scan uses magnetic waves to create images instead of radiation. Patients should be alert about any implants, allergies or pregnancy before going for any type of MRI
What does T mean in 3T, 2T, and 1.5T MRI tests?
Letter ‘T’ stands for tesla in the 3T, 1.5T and 2T, which is the unit of measure of magnetic strength of the machine. The magnetic strength is measured in tesla and based on the strength of the machine the names are given accordingly to the machines. One tesla is equal to 10,000 gauss which is almost 30,000 times the gravity surface of the earth. So, machines having more units of T are more powerful than those having lower values.
What is the difference between 1.5T, 2T and 3T MRI Scans?
The difference between 1.5T, 2T and 3T MRI scans lies in the strength of the magnetic measurement. The 3T scans are more powerful than the 2T and 1.5T scans. The 3T MRI scan is 2 times more powerful than the 1.5T MRI scan. These values give the idea and strength of test MRI. The higher the strength of the MRI, the higher the quality of the images and the easier it is to detect the abnormality.
Which MRI is Best 1.5T or 3T?
Various factors decide whether to go for a 1.5T or 3T MRI Scan. These factors include:
- Availability
- Primary usage
- Time taken to scan
- Safety
- Cost
- Image artefacts
For a better decision to go between the two MRI scans, It is always better to consult a doctor and decide whether to go for the 1.5T and 3T scans.
Usage difference
For general diagnosis, usually 1.5T MRI scans are done for examination of the conditions. General examination of chest, abdomen, pelvis etc. can be performed through 1.5T MRI. Where as 3T MRI is used to get the detailed images of the condition and the abnormality. 3T MRI get the details of even small structures inside of the body, brian, wrist, bones and neurological abnormalities.
Cost Difference
The cost of MRI scan relies on which part and what type of MRI scan you are going for. A 3T MRI scan can offer a precise and clear picture of the inner structure of your body, it is hence on the costlier side as well, as compared to a 1.5T MRI scan. The cost of a 3T MRI scan can go up to twice the amount you are likely to pay for a 1.5T scan!
Difference of Two Between 2 Scans
The difference between the two is in the amount of time they take for the scanning. A 3T MRI machine offers a quick and easier-on-patient approach while still maintaining the quality and precision of the scan images produced. Therefore, a 3T MRI scanner is as fast as it can scan the body up to and within 60 minutes. The time taken to scan also depends on the time it takes to send signals and the field strength.
Difference in Implant Safety
MRI uses magnetic waves for the detection of abnormalities. 3T MRI uses strong waves for the detection of abnormality. Since the MRI uses magnets and radio waves and not radiation, there are certain implants with which you cannot take a 3T scan at all. There are certain implants with which you can still undertake a 1.5T MRI scan safely since already explained that the 1.5 T MRI scanner doesn't use as strong a magnetic field as the 3T MRI scanner uses. It would be dangerous for you to undergo 3T scanning with these metallic implant devices. If you still do, you may be exposed to a higher risk of developing side effects or complications in the functioning of the metal device.
Difference in image accuracy and detailing
A 3T scanner is capable of providing a more clearer and detailed image. Even a 1.5T MRI scanner can produce a clear enough image but it is not as detailed as the one that a 3T scanner produces. Because the strength of the magnets in a 3T MRI scan is far more than the 1.5T MRI magnet. On the other hand, if you have certain metal devices inside of your body such as a leg rod that is placed after a severe leg fracture, the 3T MRI scanner might not produce as clear an image as the 1.5T MRI scanner may produce. It is because the amount of scattered radiation a foreign object can cause in the imaging is always more when the power of magnets is too high.
Difference in availability
While a 1.5T scanner is available at almost every diagnostic centre near you, hospital, or clinic, a 3T scanner is not available everywhere. They are usually present at prestigious private hospitals. But they are unavailable at certain places, especially at the small centres which are at the outskirts of the city.

Frequently Asked Questions (FAQs)
What is an MRI Diagnostic tool?
MRI (Magnetic Resonance Imaging) is a diagnostic tool that uses magnetic waves for the detection of abnormalities and infections in the body.
What are the benefits of an MRI?
MRI is a non-invasive radiological diagnostic procedure that is painless and accurate.
What are the uses of MRI?
Various uses of MRI include the diagnosis of abnormalities in the body like brain diseases, spinal cord diseases, cancers, injuries, fractures etc.
Who should not go for an MRI?
Persons having metallic implants and contrast allergies should not go for an MRI.
What is the difference between 1.5T and 3T MRI?
