Computed tomography, heart, with contrast material(s), including noncontrast images, if performed, cardiac gating and 3D image postprocessing; cardiac structure and morphology in congenital heart disease

Computed tomography (CT) is a sophisticated imaging technique that utilizes multiple, narrow beams of x-ray radiation directed around a single rotational axis. This method captures a comprehensive series of two-dimensional images of the heart from various angles. The data collected is then processed by a computer to digitally reconstruct a three-dimensional image of the heart, allowing for the production of thin, cross-sectional images, also known as slices. The CT procedure can be performed with or without the administration of contrast material, which enhances the visibility of the heart structures as the contrast agent circulates through the heart. A critical component of this imaging technique is cardiac gating, which addresses the challenge of capturing clear images of the heart, particularly the coronary arteries, while the heart is in motion. During cardiac gated imaging, the scanner remains inactive while the heart beats, activating only during brief moments when the heart is at rest. This approach not only yields sharp, high-resolution images but also significantly reduces the radiation exposure to the patient. The CPT® Code 0150T specifically reports on cardiac CT imaging that includes the use of contrast material, the acquisition of noncontrast images if performed, the application of cardiac gating, and the postprocessing of three-dimensional images, all aimed at evaluating the cardiac structure and morphology in patients diagnosed with congenital heart disease.
