In this work we describe a new method of field-cycling
relaxometric imaging based on the view-sharing technique
known as keyhole imaging. We have employed this
technique to generate images containing a new form of
endogenous contrast based on the variation of R1 with
the external magnetic field. Relaxometric imaging
results are presented from a phantom study and a human
volunteer in order to demonstrate the accuracy and
practicality of the method.
