Gated SPECT assessment of left ventricular function is sensitive to small patient motions and to low rates of triggering errors: A comparison with equilibrium radionuclide angiography

Contrary to RNA, gated SPECT is vulnerable to small patient displacements, and thus, specific efforts might be useful for limiting this potential cause of erroneous results. Both techniques may be affected by low rates of triggering errors, suggesting that small acceptance windows on cycle length should be recommended not only for RNA but also for gated SPECT.
