Key result
Repeated planar radionuclide ventriculography within 3 hours using a single 500 MBq dose of [Tc]pertechnetate showed excellent reproducibility for LVEF (mean difference 0.94%; 95% CI -2.7 to 4.5).

Does repeated planar radionuclide ventriculography within 3 hours using a single standard dose of [Tc]pertechnetate provide reproducible LVEF measurements in patients?
Mean Difference: 0.94 (95% CI -2.7–4.5)
p-value: p=NS
Repeated radionuclide ventriculography with a 3-hour interval using a single standard dose of 500 MBq of [Tc]pertechnetate is highly reproducible for LVEF measurement.
Vleuten et al. (2005) reported an observational. Repeated planar radionuclide ventriculography vs. Initial planar radionuclide ventriculography was evaluated on Mean LVEF difference between baseline and repeat planar radionuclide ventriculography (MD 0.94, 95% CI -2.7 to 4.5, p=NS). Repeated planar radionuclide ventriculography within 3 hours using a single 500 MBq dose of [Tc]pertechnetate showed excellent reproducibility for LVEF (mean difference 0.94%; 95% CI -2.7 to 4.5).
