A past operating mode in CT was to focus on image quality with less emphasis on limiting CT dose. This may have been practical Abstract. Cardiac and paracardiac masses include benign and malignant tumors and nontumoral mass lesions. Metastatic tumors are far more common than primary cardiac tumors. Although echocardiogra¬phy and magnetic resonance imaging (MRI) are the most frequently used imaging examinations, multi¬detector computed tomography (MDCT) is often used to evaluate these masses, particularly when MRI is contraindicated. MDCT is not only fast but also has high spatiotemporal resolution, multiplanar recon-struction capabilities, and a wide field of view, providing detailed evaluation of cardiac and paracardiac masses and adjacent structures, including the lungs. Knowledge of the characteristic and atypical imaging appearances is essential for thorough evaluation of these masses. In this pictorial review, the CT appear¬ances of the most common cardiac and paracardiac masses are discussed and illustrated. ©2011 Society of Cardiovascular Computed Tomography. All rights reserved.
