In order to obtain a patient-specific AIF for DCE-MRI,
it has been proposed to measure the T1 of blood in a
large vessel. This work demonstrates through the use of
physical and virtual phantoms that these measurements
are highly compromised by flow at physiological rates
and that this strategy may be unfeasible.
