“…Detailed descriptions of the available reconstruction options for each protocol, taking into account the average heart rate and the variability during data acquisition, have been published in a considerable number of studies [11, 14, 31]. Reconstructions of data acquired in the retrospective spiral mode can be performed either using a fraction of the R-R interval or an absolute time-point prior to or following the R-wave of each cardiac cycle, the latter showing some advantages in case of variable heart rates and arrhythmia.…”

Over the past years, the number of coronary computed tomography angiography (CTA) studies performed worldwide has been steadily increasing. Performing a coronary CTA study with appropriate protocols tailored to the individual patient and clinical question is mandatory to obtain an image quality that is diagnostic for the study purpose. This process can be considered the primary mainstay of each coronary CTA study. The secondary mainstay is represented by the correct analysis and interpretation of the acquired data, as well as reporting of the pertinent imaging findings to the referring physician. The latter process requires knowledge of the advantages and disadvantages of various post-processing methods. In addition, a standardized approach can be helpful to avoid false-positive and false-negative findings regarding the presence or absence of coronary artery disease. By implementing various radiation dose reduction techniques, care needs to be taken to keep the radiation dose of coronary CTA as low as reasonably achievable while maintaining the diagnostic capacity of the examination. This review describes a practical approach to the analysis and interpretation of coronary CTA data, including the standardized reporting of the relevant imaging findings to the referring physicians.

“…A large number of studies have described the various protocols available, their individual use depending on the patient’s habitus and heart rate, and the different post-processing options [10, 11]. Interestingly, studies detailing the analysis and interpretation as well as reporting the data are conspicuously rare.…”

“…Retrospective gating acquires images through the entire cardiac cycle which allows for image reconstruction at different times in the cycle. 2 Prospective ECG triggering acquires images at a specific time, substantially reducing radiation exposure, but can limit the options for image reconstruction. 6 Following radiation safety policies, prospective gating should be used whenever feasible; nonetheless, if acquisition of images throughout the cardiac cycle yields pertinent information (atrial septal aneurysm, tumors with mobile components), retrospective gating should be favored.…”
