The use of gated perfusion scanning in the assessment of left ventricular volume

A total of 34 patients underwent both gated SPECT perfusion imaging and ech ocardiography, with each test blinded to the other. Wall motion analysis, c alculation of ejection fraction and ventricular volume were obtained by eac h technique. A close correlation was observed between the ejection fraction s calculated by each method (r = 0.79). There was a Less close relationship between the left ventricular volumes calculated by each method (r = 0.61) this is probably due to the errors which result from geometric assumptions for each technique. Wall motion analysis revealed a good Level of agreement between each method with no significant discrepancies between the techniqu es. (C) 2001 Elsevier Science ireland Ltd. All rights reserved.
