An MRI scan is often associated with claustrophobia and fear. However, there are different types of MRI scanners like the newer 3T ones with ambient experience that significantly reduce the incidence of claustrophobia. So, if you need an MRI scan, what kind of scanner should you choose? The first thing to remember is that every scanner has a different magnetic strength, measured in Tesla units. Generally, the MRI machines available today have strengths ranging from 0.2T to 3.0T – of which the 3.0T MRI produces the clearest images. Apart from the Tesla strength, MRI machines are differentiated into 3 categories based on their structure and design – these include closed MRI machines, wide bore MRI machines, ‘truly’ open MRI machines and open upright MRI scanners.
A common rule of thumb? The lesser the diameter of the bore of the scanner, the greater the clarity of the image.
Let’s have a look at the different MRI scanners available.
