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.

Imaging-based COVID study finds blood clots twice as likely with infection vs. vaccination

A retrospective analysis of cross-sectional venograms shows only 4.5% of a teaching hospital’s COVID-vaccinated patients had a clotting condition in early 2021. Meanwhile the rate for the unvaccinated was 10.1%.
