Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

Left, a 3-D rendering of a heart from a cardiac CT exam. Right, a lung-CT exam showing the heart and ground glass lesions in the lungs of a COVID-19 patient. CT has become a front-line imaging modality in the COVID era because it offers both cardiac and lung information to help determine a patients disposition with chest pain, COVID-19 and COVID-caused myocarditis and pulmonary embolism. #COVID19 #CCTfirst #YesCCT
