Compared with other investigations, images produced from arrhythmia-insensitive rapid (AIR) cardiac T₁ mapping pulse sequences contain significant random noise which limits the accuracy of quantitative measurements. Therefore, denoising filters were used to reduce noise present in the images. From our analysis, the non-local means filter was best able to reduce the amount of noise while still maintaining accurate T₁ measurement data.
