This paper describes a noise-reduction technique applicable to multiple-measurement systems. This method, known as measurement-dependent filtering (or MDF), can be used to advantage in a number of MRI applications. We present the general theory for one of these applications, material-canceled projec

## Abstract The application of __T__~1~ in the rotating frame (__T__~1ρ~) to functional MRI in humans was studied at 3 T. Increases in neural activity increased parenchymal __T__~1ρ~. Modeling suggested that cerebral blood volume mediated this increase. A pulse sequence named spin‐locked echo plana
