Perfusion MRI is routinely used for brain tumor diagnosis and treatment follow-up. This work compares the performance of the standard dynamic susceptibility contrast sequence against a new fast dynamic contrast-enhanced sequence for brain metastasis follow-up after stereotactic radiosurgery. This new sequence enables the simultaneous measurement of blood brain barrier permeability that could help differentiate tumor recurrence and pseudo-progression. Our preliminary results show a correlation between relative cerebral blood volume estimates from both methods. A trend towards significance after analysis of thirteen lesions is expected to reach significance after inclusion of the remainder of our cohort.
