Persistent defects were associated with more PH/RV dysfunction; leaves open scintigraphy's additive value beyond echocardiography given high variability.
Can perfusion lung scintigraphy differentiate patients with persistent pulmonary hypertension/right ventricle dysfunction from those without after acute pulmonary embolism?
Lung scintigraphy can help identify patients at risk for persistent pulmonary hypertension or right ventricular dysfunction after acute pulmonary embolism, but it cannot replace echocardiography due to high individual variability.
Ribeiro et al. (1999) studied this question.
