1.5T vs. 3.0T MRI Machines

Overview of Differences

So many decisions and so many products to choose from.  

Remember,  there are more things to consider besides cost when purchasing an MRI machine. Such as location, shielding, and safety. In today’s article we will go over the differences between 1.5T vs. 3.0T. We’ll cover the pros and cons of each unit.

Things to Consider before Purchasing an MRI Machine

  1. Cost: What is your budget? For most imaging departments this will be the limiting factor. (1.5 T units are budget friendly and the obvious choice)
  2. Cases performed: Abdomens, extremities, etc. can be performed on 1.5T and 3.0T MRI machines. If performing vascular, neuro and brain, or other intricate exams where detail is the priority, then 3.0T is the better choice.
  3. Patient volume: Full schedule where speed is the priority or turnaround times aren’t critical. 3.0T machines can provide accurate images in less time versus 1.5 T machines
  4. Patient population: pediatrics, bariatric patients etc. If scanning larger patients the bore size of the magnet will be a consideration along with magnetic strength.

For referance, Tesla indicates the strength of a magnetic field. 1.5T is about 15,000 gauss, which is 30,000 times stronger than the magnetic field of the earth.

3.0T is double the strength which means it is 60,000 times stronger than
