Purpose of Review
Cardiac computed tomography (CT) is an established tool for evaluating cardiovascular disease, which may incidentally depict extracardiac findings (ECF). The aim of this study is to identify the spectrum and the prevalence of incidental findings detected on cardiac CT.
Recent Findings
This systematic review found a median ECF occurrence of 45% in cardiac CT (range, 7–100%) among papers published between 2006 and 2018. The median clinically significant ECF occurrence was 17% (1–67%) among studies. Respectively, the five most commonly reported ECF were lung nodules or masses, lung parenchymal changes, lymphadenopathy, emphysema, and liver nodules or cysts.
Summary
ECF are frequently encountered on cardiac CT. Therefore, interpreting physicians should be aware of the occurrence of clinically significant findings and be familiar with the follow-up recommendations endorsed by current guidelines.
