Rapid advances in imaging technology have dramatically expanded the diagnostic capabilities of physicians in general and cardiologists in particular. An increasing number of cardiologists are evaluating the feasibility of using new imaging technologies to enhance patient care. In addition to deciding which imaging modalities are most effective, physicians will choose whether to acquire these new technologies or refer patients to other locations. This report will provide insight into cardiologists’ roles in ordering and performing cardiac imaging procedures today and in the years to come. The report is based on interviews with 220 cardiologists to learn which imaging scans are currently ordered by cardiac condition, where these scans are performed (in their office or in local hospitals or imaging centers), and what they expect to order for these same conditions 3 years from now. It includes comparisons to data collected 2 years ago.
