Comparison of cardiac CT systems including Dual Source CT

The following question was sent by E.I. Steenkamp, South Africa:

Can you direct me to specific articles explaining the pros (and cons) of Cardiac CT and its place in Cardiology?
Cardiac CT in general please. I also would like some specific information why the DSCT is more appropriate, if so.
Regards.
