Fast approximation to pixelwise relaxivity maps: validation in iron overloaded subjects

PURPOSE: Liver iron quantification by MRI has become routine. Pixelwise (PW) fitting to the iron-mediated signal decay has some advantages but is slower and more vulnerable to noise than region-based techniques. We present a fast, pseudo-pixelwise mapping (PPWM) algorithm. MATERIALS AND METHODS: The...
