The components and value of a CVIS are enumerated and explained, and how the Radiology analogy can and can’t be useful in understanding Cardiology imaging. Vendor product strategies are described, including why Philips purchased Witt, Agfa purchased Heartlab and Emageon purchased Camtronics. He reviews the needs of those who read CT angiograms and the importance and the intricacies of structured reporting. Part 2, Implementing CVIS, is scheduled for November 7.
