ON THE COVER
Precise and reliable assessment of left ventricular function and dimensions is prognostically important in cardiac patients. Comparison of SPECT and multislice CT for such assessments is pertinent because of the availability of hybrid scanners combining the 2 techniques. SPECT and multislice CT have been found to agree well over a wide range of clinically relevant values for left ventricular ejection fraction and functional parameters, but interchangeable use of the 2 techniques should be avoided for left ventricular volume, muscle mass, and regional wall motion.
