Jogi J, et al. - The ability of ventilation/perfusion single-photon emission computed tomography (V/P SPECT) to evaluate and quantify pulmonary congestion was assessed when used as a non-invasive method in heart failure (HF) patients, using right heart catheterization as reference method. Also, researchers determined how V/P SPECT performed in the clinical setting vs chest X-ray (CXR). Based on the findings, they concluded that, for the detection and quantification of pulmonary congestion in patients with HF, V/P SPECT can be used as a non-invasive method. Also, V/P SPECT offered more accurate diagnosis of pulmonary congestion in the clinical setting, vs CXR.
