Background/Purpose
The 64-slice multidetector CT (64-MDCT) has bolstered the sensitivity and specificity of coronary CT angiography (CCTA) for detecting coronary artery disease. We performed this study to understand the current status of CCTA using 64-MDCT, so as to determine further promotion and optimal regulation schemes of CCTA in Taiwan.Methods
Information about CCTA from 68 domestic hospitals with 64-MDCT was collected by means of a questionnaire from July 2009 to January 2010. The studied details included: (1)聽the implementation background of CCTA; (2) the interdisciplinary cooperation and report processing of CCTA; and (3) the promotion strategy of CCTA.
Results
The majority of CCTA sites (89.7%) were administered by diagnostic radiologists. Most cardiologists and cardiac surgeons have confirmed its clinical value by referring patients to undergo CCTA. Of the CCTA reports by radiologists, 41.2% had their report supplemented by referring cardiologists. Such cooperation amongst specialists promoted the development of CCTA. Of CCTA studies, 89.7% included coronary calcium scoring. Most (60.3%) respondents asserted the cost of a study to be 15,000 to 20,000 new Taiwan dollars. Nearly two-fifths (41.2%) of the respondents supported the restriction of subjects for CCTA to those who were high risk group for coronary artery disease or those > 40 years of age.
Conclusion
Diagnostic radiologists are primarily in charge of managing CCTA sites in Taiwan. The interdisciplinary cooperation amongst radiologists and cardiologists in reporting CCTA may expedite the development of CCTA. The domestic radiologists are expected to standardize the process, which includes interpreting and reporting CCTA findings.
