To highlight the importance of examiningthe heart in every thoracic CT examination , even if there is no suspicion of cardiac disease ; To suggest a systematic check-list approach for the evaluation of every cardiac structure; To describe cardiac abnormalities detectable in non-ECG- gated CT .
Cardiovascular disease is one of the leading causes of morbidity and mortality. Improvements in CT technology havereduced scanning times and now provide images of the heart that are much less degraded by cardiac motion artifacts and that allow a more detailed evaluation of the cardiac structures. Therefore, although frequently overlooked by radiologists ,
many incidental cardiac findings can be obtained from non-ECG-gated CT, which can explain the clinical manifestations or influence the...
Imaging findings OR procedure details
CORONARY ARTERY DISEASE √ Normal origin? ( Fig. 1 ) ⇒ Right coronary artery should arise from the right coronary sinus and left coronary artery from the left coronary sinus (can be hard to assess without ECG-gating).
The left anterior descending artery should originate from the left coronary artery. Coronary artery calcifications ( Fig. 2 ) The amount of coronary artery calcification correlates with coronary artery disease,
one of the leading causes of death worldwide.
CT is highly sensitive...
Cardiac evaluation is often overlooked in non-gated CT. Many of the cardiac findings mentioned can have an impact in the patient’s prognosis. Every radiologist should be familiar with these pathologies and report them whenever present.
