Gated technetium-99m-tetrofosmin SPECT and cine MRI to assess left ventricular contraction.

Abstract

Gated 99mTc-tetrofosmin imaging provides an accurate assessment of myocardial wall motion, thickening and thickness in normal left ventricles but is less valuable in poorly functioning ventricles. Six percent of segments could not be assessed because of inadequate tracer uptake.
