The presented work aims to compare maps of the fractional pulmonary blood volume (fPBV) generated using the Two-Compartment Inversion Recovery (TCIR) method to the clinical reference standard single photon emission computed tomography/computed tomography (SPECT/CT) in an animal experiment. For the assessment of the performance of TCIR seven anesthetized pigs were studied via CT, as well as dynamic contrast enhanced MRI and SPECT. This animal experiment demonstrated a qualitative agreement in the assessment of blood distribution between contrast agent free TCIR and DCE MRI and conventional SPECT/CT.
