PerfusieCTMR
PerfusieCTMR is a multimodal imaging concept that combines perfusion data acquired with computed tomography (CT) and magnetic resonance imaging (MRI) to characterize tissue hemodynamics. It may be implemented on hybrid CT-MR systems that can perform CT perfusion (CTP) and MR perfusion in a single examination, or through sequential CT perfusion and MR perfusion studies with subsequent image fusion and co-registration to a common space.
CT perfusion measures dynamic iodinated contrast passage to estimate cerebral blood flow (CBF), cerebral blood volume
Potential advantages include complementary information: CT provides rapid acquisition and high spatial resolution; MR yields superior
Limitations include increased contrast load and radiation exposure, longer exam times, the need for expertise in
