A magnetic resonance method for imaging blood volume in parenchyma via magnetic transfer (MT) includes: determining a MT effect of parenchyma; determining a MT effect of tissue; and quantifying the parenchymal blood volume using the difference between the MT effect of parenchyma and the MT effect of tissue. In one embodiment, the parenchymal blood volume is quantified through the following: MTRpar=MTRtissue(1−BV/Vpar), where MTRpar is the magnetization transfer ratio of parenchyma, MTRtissue is the magnetization transfer ratio of tissue, BV is the blood volume, and Vpar is a total parenchymal water volume.
