All MRI machines are calibrated in "Tesla Units". The strength of a magnetic field is measured in Tesla or Gauss Units. The stronger the magnetic field, the stronger the amount of radio signals which can be elicited from the body's atoms and therefore the higher the quality of MRI images.

1 Tesla = 10,000 Gauss
Low-Field MRI= Under .2 Tesla (2,000 Gauss)
Mid-Field MRI= .2 to 0.6 Tesla (2,000 Gauss to 6,000 Gauss)
High-Field MRI= 1.0 to 1.5 Tesla (10,000 Gauss to 15,000 Gauss)

Advantages of 3 Tesla MRI

The 3T MRI has twice the field strength of most conventional MRI scanners, which typically operate at 1.5 Tesla. The 3T strength can increase the imaging resolution by 16 times. Tesla is a unit of measure for magnetic field strength. Three tesla is equivalent to 30,000 times the earth’s magnetic field. The 3T MRI captures images with a level of detail, clarity and speed never before possible.

Some of the procedures that the 3T MRI system will particularly benefit include:
MR angiography
• Neurological/brain imaging
• Spine studies • Orthopedic – including elbow, wrist, hip, knee, foot and ankle
• Prostate
• Pelvis – Male and Female
• Abdominal
• Functional imaging, spectroscopy, and brain fiber tracking
