A very well designed study. However, should there be a clinical concern when the intra- and inter-observer variability coefficients for EF are 8.1 and 9.7%? Is the clinical management of a patient the same when his EF is 45% rather than 53.1%?

This is an excellent study using CT for non-coronary purposes. There continues to be more interest in using CT for purposes outside the coronary artery tree due to its high spatial resolution. As radiation exposure continues to go down, the trend towards increased use of CT will likely continue.
