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.

Urinary stones in the ED: What will it take for ultrasound to gain ground on costly, radiative CT?

Professional consensus supports the use of ultrasound for initial imaging evaluation of patients presenting in the ED with suspected urinary stone disease (USD). However, as of 2018, only 2% of these patients received ultrasound while some 59% had CT.

Sean Fain, PhD, vice chair of radiology and research and a professor of radiology, Division of Cardiovascular and Thoracic Imaging, University of Iowa, discusses how long-COVID lung damage can be tracked using xenon (Xe) gas magnetic resonance imaging (MRI) and quantitative computed tomography (CT). He spoke to Health Imaging at RSNA 2022.

Follow-up care improves with reporting template for incidental findings

Use of the template, which included PCP notifications, also resulted in an increase of biochemical testing, follow-up imaging and specialist referrals in patients with incidental adrenal masses.

why are T. Rex arms so short?

Experts hope CT can help unlock age-old question: Why were T. Rex arms so short?

Experts are hoping that, by imaging the dinosaur’s shoulder girdle and forelimb, they can create a digital model that could help in determining a T. Rex arm’s range of motion and strength.
