Why the study?
Does radionuclide equilibrium gated blood-pool imaging reliably assess aortic and mitral regurgitation in patients with valvular disease?
Does radionuclide equilibrium gated blood-pool imaging reliably assess aortic and mitral regurgitation in patients with valvular disease?
Caution must be exercised when using radionuclide equilibrium gated blood-pool imaging to assess valvular regurgitation, specifically in how ventricular regions of interest are defined.
Caution advised in defining ventricular ROIs for gated blood-pool imaging; leaves open reliability for regurgitation assessment pending validation.
A non-invasive nuclear medicine technique for the assessment of aortic and mitral regurgitation may be of importance in the management of patients with valvular disease. Rigo et al (1979) introduced a method based on measuring the ratio of the left ventricular stroke volume to the right ventricular stroke volume from radionuclide equilibrium gated blood-pool images of the heart. In this paper we report our results using this technique. They indicate that caution should be exercised, and in particular that methods used to define the ventricular regions of interest must be carefully examined.
