Does Thallium-201 myocardial scintigraphy correlate with right ventricular systolic pressure and pulmonary artery mean pressure in patients with right ventricular overloading?
The RV/IVS uptake ratio derived from Thallium-201 myocardial scintigraphy closely correlates with right ventricular and pulmonary artery pressures, providing a non-invasive parameter for estimating right ventricular overloading.
Owada et al. (1982) studied this question.
