Brain DCE MRI is a powerful technique for evaluating
blood-brain-barrier leakage in tumors, multiple
sclerosis lesions, and other neurologic disorders.
DCE-MRI is an active area of research but lacks a gold
standard making it difficult to evaluate novel image
acquisition, reconstruction, and processing techniques.
We introduce the use of patient-derived digital phantoms
that provide ground-truth and the ability to generate
data with arbitrary temporal resolution, and perform
sensitivity analysis over a broad range of inputs. We
demonstrate its application to the evaluation of sparse
sampling and constrained reconstruction methods.
