The major reason for artifacts in T2-weighted prostate imaging is motion-induced blurring caused by slight displacements between averages. Here, a non-rigid elastic registration is proposed to properly align the images before averaging. The method is evaluated in 12 patients and is shown to improve image quality in 71% of all investigated cases. Identification of pathology was improved in 42%. While only 58% of the conventional images achieved good or excellent image quality, this was the case for 88% when applying motion correction. As demonstrated, non-rigid registration results in clearly reduced motion artifacts and improves image quality and diagnostic confidence.
