Why the study?
Does gated blood pool scintigraphy improve detection of abnormalities of the ascending aorta in patients undergoing ventricular function evaluation?
Does gated blood pool scintigraphy improve detection of abnormalities of the ascending aorta in patients undergoing ventricular function evaluation?
Gated blood pool scintigraphy, typically used for ventricular function, may also be useful for detecting and evaluating abnormalities of the ascending aorta.
May enable incidental aortic evaluation during routine gated studies; leaves open prospective validation before practice change.
Radionuclide angiography has been used for visualization of aortic arch pathology. Gated blood pool scintigraphy generally has been reserved for the evaluation of ventricular function. By observing the aorta in relation to other cardiac structures, additional information about relative size and shape is available, and can be integrated with ventriculographic observations. This may enhance understanding of the mechanism of disease in the individual patient. Five selected case histories illustrating this point are presented. The last example demonstrates the ability of the technique to uncover unsuspected thoracic aorta pathologic findings. The sensitivity and specificity of this technique to diagnose aortic disease requires further study.
