Abstract

Since its introduction in the 1970s diagnostic computed tomography CT imaging has grown rapidly and developed into a standard diagnostic test for a wide variety of cardiovascular conditions Although this has undoubtedly led to improved medical care it has also been associated with a significant increase in populationbased radiation exposure and the potential downstream increase in cancer is a justified concern For cardiovascular CT new CT scanner technologies were initially directed toward maximizing image quality rather than minimizing radiation exposure Only more recently have technologic advances yielded dosesaving protocols for cardiovascular applications with impressive reduction of radiation exposure The achievable limits of populationbased exposure are dependent on responsible evidencebased use of CT for cardiovascular imaging as well as exploitation of available and emerging dosesaving strategiesConflicts of interest P Schoenhagen none CThompson has received grant support from Philips Healthcare CT Division SS Halliburton has received grant support from Philips Healthcare CT Division and Siemens Medical Solutions Angiography Division has received honoraria from Philips Healthcare CT Division as a Medical Advisory Board member and has received payment from Philips Healthcare CT Division for being on the speakers’ bureau
