Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

COVID causes increase risk of clotting. Example of a pulmonary embolism. CT pulmonary angiograms in a 77-year-old man with COVID-19 and a saddle embolus to pulmonary arteries (black arrow in A) extending into right and left pulmonary arteries (white arrows) in (A, B) axial and (C) coronal planes. Arrowheads show pulmonary changes associated with COVID-19 and possible lung infarction (black arrow in C). (D) Axial image at the level of the ventricles shows right-sided heart strain. RSNA.
