Pulmonary regional blood flow: validation of low-dose two-volume dynamic CT perfusion imaging in a swine model

Abstract Background We aimed to validate a low-dose two-volume pulmonary computed tomography (CT) perfusion technique. Methods Five Yorkshire swine (weight 53.6 ± 2.6 kg) underwent 21 independent CT perfusion acquisitions. Intravenous contrast material (370 mg/mL iodine, 0.5 mL/kg) and saline chaser...
