RV visualization on thallium-201 imaging was associated with elevated RV pressure; hypothesis-generating for noninvasive detection, requiring prospective validation.
Does visualization of the right ventricle on resting thallium-201 myocardial imaging detect right ventricular pressure or volume overload in patients?
Resting thallium-201 myocardial imaging is a sensitive noninvasive method for detecting right ventricular pressure or volume overload compared to standard chest x-ray, echocardiogram, and electrocardiogram.
