Lung Perfusion in Patients With Pulmonary Hypertension: Comparison Between MDCT Pulmonary Angiography With minIP Reconstructions and 99mTc-MAA Perfusion Scan

Abstract

MinIP reconstructions can identify different patterns of pulmonary parenchymal attenuation, which show high concordance with perfusion patterns seen on radionuclide studies in patients with pulmonary hypertension. MinIP is a promising technique to evaluate lung perfusion in PH and may be used as an alternative to scintigraphy in the diagnostic work-up of these patients.
