AB Paired scintigraphic and cine CT studies were performed on 29 patients to assess the accuracy of three scintigraphic methods currently available for determination of right ventricular ejection fraction (RVEF). Following a bolus injection of 30 mCi [99mTc]pertechnetate, a serial mode acquisition of the first transit through the heart was recorded. Processing was performed in three ways: beat-by-beat (fixed ROI), equilibrium multigated acquisition (MUGA) (variable ROI), and first-pass MUGA (variable ROI). RVEF values determined with the first-pass MUGA technique showed the best correlation with cine CT values, while those determined with the beat-by-beat or the equilibrium MUGA techniques consistently underestimated the RVEF. Thus, the scintigraphic technique using a first-pass gated format with variable ROI appears to be reliable by correlation with cine CT as an inexpensive, noninvasive method for evaluation of RV function.
