The increasing use of coronary computed tomographicangiographic (CTA) requires the establishment of standardsmeant to ensure reliable practice methods and qualityoutcomes. The Society of Cardiovascular ComputedTomography Guidelines Committee was formed to developrecommendations for acquiring, interpreting, and reportingof these studies in a standardized fashion. Indications andcontraindications for specific services or procedures are notincludedinthescopeofthese documents.Theserecommen-dations were produced as an educational tool for practi-tioners to improve the diagnostic care of patients, in theinterest of developing systematic standards of practice forcoronary CTA based on the best available data. Because ofthe highly variable nature of individual medical cases, anapproach to scan performance that differs from these guide-lines may represent an appropriate variation based on alegitimate assessment of an individual patient’s needs.
