Where There is certainly more sign using a 1.5T magnet than the usual one.2T magnet, you will discover fantastic alternatives concerning what can be achieved with the additional sign – you'll be able to operate shorter scan occasions (reduces feasible motion) and also have greater good quality pictures. 

The Mind, spinal cord and nerves, and also muscles, ligaments, and tendons are viewed far more clearly with MRI than with normal x-rays and CT; for this reason MRI is commonly accustomed to graphic knee and shoulder injuries.

The image good quality of an MRI depends on signal and area power.  So a 3T device has much more sign than the usual 1.5T machine.  3T pictures can provide extremely crystal clear and vivid photographs and will frequently be carried out faster, lowering General scan time.
