A quantitative dual-isotope single-photon emission tomography (SPET) technique for the
assessment of lung ventilation (V) and perfusion (Q) using, respectively, technetium-99m …

The aim of this study was to evaluate a method for quantification of inhomogeneity in
ventilation single-photon emission tomography (SPET). Nine emphysematous patients, nine …

To date, there has been neither a good method to clarify the three-dimensional distribution
of pulmonary ventilation/perfusion (V. A/Q.) ratios, nor a convenient way to assess V. A/Q …

The purpose of this study was to evaluate the effects of gravity and lung volume on regional
pulmonary perfusion using technetium-99m macroaggregated albumin (99m Tc MAA) single …
