Routine Chest CTA Reliably Quantifies Left Ventricular Myocardial Mass

Background: Routine chest computed tomography angiography (CTA) is the primary imaging modality for thoracic aortic disease, yet cardiac information within these examinations remains underutilized. We evaluated whether left ventricular myocardial mass (LVMM) can be reliably quantified from routine non-electrocardiographically (ECG)-gated chest CTA and its application in thoracic aortic pathology. Methods: CTA scans were obtained from 257 patients without aortic disease and 181 patients with thoracic aortic aneurysm or dissection. LVMM was quantified using automated three-dimensional segmentati
