Key result
Recognizing normal cardiac CT anatomy and variants prevents misinterpreting benign findings as pathology.
Highlights common cardiac CT imaging pitfalls where normal anatomy and variants can simulate disease.
Alerts imagers to common CT pitfalls mimicking thrombus; leaves open prospective assessment of misdiagnosis rates.
Advances in computed tomography have led to continuous improvement in cardiac imaging. Dedicated postprocessing capabilities, faster scan times, and cardiac gating methods reveal details of normal cardiac anatomy and anatomic variants that can mimic pathologic conditions. This article will review normal cardiac anatomy and variants that can mimic disease. Radiologists should be familiar with normal cardiac anatomy and anatomic variants to avoid misinterpretation of normal findings for pathologic processes.

Terpenning et al. (2015) conducted a review in Cardiac anatomy and imaging variants. Multidetector computed tomography was evaluated. Awareness of normal cardiac anatomy and variants on CT is crucial for cardiothoracic imagers to avoid misinterpretation of normal findings as pathologic processes.
