Bottom Line: 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.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.

ABSTRACT
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.

Fig1: Curved multi-planar reformations of the right coronary artery providing an excellent depiction of the vessel along its entire course

Mentions: Multi-planar reformations (MPR) display the dataset in any imaging plane of the three-dimensional space. MPR are easily reconstructed and may be saved and archived to PACS (picture archive and communications system) for further analysis if desired. If reconstructed along a vessel centerline (i.e., “curved” MPR), the depiction of even long and tortuous coronary arteries is possible on a single image. Curved MPR are considered very important for the diagnosis, depiction, and illustration of coronary artery disease because usually the course of coronary arteries is tortuous and complex to view on one two-dimensional image. Curved MPR allow for a display of a whole vessel or coronary artery segment on one image, thus enabling the illustration of a coronary artery stenosis in its full extent (Fig. 1). In general, MPR may be reconstructed quickly on all common post-processing systems and are considered mandatory for the diagnosis of coronary artery disease because a coronary stenosis should be validated on a second imaging plane in all cases to avoid false-positive findings.
