  • QUANTITATIVE DIFFERENTIAL PULMONARY PERFUSION - MR-IMAGING VERSUS RADIONUCLIDE LUNG-SCANNING Silverman, J. M., JULIEN, P. J., Herfkens, R. J., Pelc, N. J. RADIOLOGICAL SOC NORTH AMERICA. 1993: 699-701

    Abstract:

    To compare the results of quantitative analysis of differential pulmonary artery blood flow performed with phase-contrast cine magnetic resonance (MR) images with those of differential radionuclide pulmonary perfusion scanning in preoperative lung transplantation patients.Forty preoperative lung transplantation patients underwent prospective, quantitative analysis of differential pulmonary artery blood flow performed with MR imaging and radionuclide pulmonary perfusion scanning. MR imaging analysis was performed at 1.5 T with a phase-contrast cine pulse sequence to acquire data perpendicular to each central pulmonary artery.Comparative analysis of differential pulmonary perfusion showed excellent correlation between the two modalities in all patients (P = .0001). MR imaging enabled calculation of the pulmonary artery blood flow to each lung; radionuclide lung scanning enabled only calculation of relative perfusion to each lung.MR imaging is as effective as radionuclide lung scanning in assessment of relative, and superior for determination of absolute differential, pulmonary perfusion.
