In this work we present a new technique for fast T1 estimation where the intensity of each pixel is linearly related to its T1 value. The technique is based on a modified Double Inversion Recovery pre-pulse and only requires the acquisition of a single 2D or 3D dataset. The technique was validated in a T1 phantom and in a pre-clinical study of renal perfusion using a gadolinium based contrast agent. Potential applications include fast T1 quantification in myocardial perfusion, infarct or fibrosis imaging.
