MARS MRI which is abbreviated for Metal Artifact Reduction Sequences are one of the recent trends in magnetic resonance imaging.

MARS MRI sequences can be created by us, even if your think your scanner is impossible to get MARS sequences to work.   MARS are much easier to create on systems that are high field (1.5 Tesla) or even low to moderate field strength systems such as a 0.7T or a 0.35T, but on the ultra high field system (3.0Tesla) the MARS sequences can be difficult.   The 3T has a higher susceptibility to metal artifacts, plus the metal gets warmer faster from a physical factor known as SAR (Specific Absorption Rate.)

The benefit of MARS MRI sequences allow visualization of pathology and anatomy closer to the metal, where as on typical MRI sequences, there is so much distortion and signal theft, the radiologist is unable to determine if a diagnosis or pathology is present.

We know how to setup MARS MRI sequences on your MRI system, and can help you capture a market share, you would normally not find otherwise.


The 3T MRI system has four times (4X) the SAR that a 1.5T system has, even though it may have twice the signal to noise during the image acquisition phases.

MARS (metal artifact reduction sequence) for MRI.

Metal artifact reduction sequences are valuable especially if one is concerned about infection around a metal implant.  Harrington rods in the lumbar spine, metal hip replacements, shoulder pins, metal knees replacements, ankle screws, and other orthopedic rods, screws, metal parts and even braces when scanning the brain can all disrupt MRI signal and disguise pathology.

Settings can be altered on MARS MRI so that tissue closer to the metal will demonstrate signal where with the regularly run sequence, it could be very difficult to visualize any pathology at all near the metal.

If you would like to have MARS MRI sequences setup on your MRI system for some of the implants mentioned earlier on this page, then
