Quantitative proton density mapping: correcting the receiver sensitivity bias via pseudo proton densities

► Proton density mapping based on linearity between R1 and 1/PD in brain tissue. ► Method tested for healthy subjects and four clinical cases (MS, stroke, tumours). ► New method yields similar results as bias field correction in healthy subjects. ► New method yields more plausible results for brain tumours. ► ROI analysis for six healthy subjects and comparison with literature values.
