iMARIterative metal artifact reduction
The iterative algorithm for metal artifact reduction, iMAR,1 allows artifacts—often caused by implants, artificial joints, or pacemakers—to be significantly reduced, thus improving the image quality of your CT and attenuation-corrected PET and SPECT images. The ability to see more detail in these types of challenging exams leads to efficient image interpretation and accurate quantification.

The amount of metal artifact reduction and corresponding improvement in image quality depends on a number of factors including: composition and size of the metal object, patient size, anatomical location and clinical practice. It is recommended to perform reconstruction with iMAR enabled in addition to conventional reconstruction without iMAR.
