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.

Dual-energy CT offers insight into how lung cancer patients might respond to surgery

“In patients with lung cancer, DECT has further potential to quantify postsurgical global and regional changes in lung volume and perfusion,” authors of a new paper in AJR suggested.

The fall and rise of trauma CT on the front and back of COVID-19

When COVID-19 social-distancing orders eased across a densely populated county in the southwest, trauma visits spiked 35% over the pre-pandemic normal. This was accompanied by a 17% increase in average daily trauma CT exams.

A GE Revolution CT system on display at the 2022 Society of cardiovascular Computed Tomography (SCCT) meeting is an example of the types of the systems being sought in the U.S. and Western Europe replacement CT market. It features AI enhanced features to automate protocol and help reduce dose, 160 mm of anatomical coverage per rotation and offers spectral imaging using fast kV switching between different energies during one scan.

14 House members—7 Democrat, 7 Republican—press CMS to step up its game on CCTA

A bipartisan group in the U.S. House is asking CMS to acknowledge the cost-effectiveness of coronary CT angiography by comprehensively covering the exam for patients who present with acute but stable chest pain or other early signs of arterial plaque buildup.

Risks of ionizing radiation exposure: Have patients been duped by internet misinformation?

The internet is a known breeding ground for misinformation, but political ideologies aside, how do popular medical/healthcare platforms hold up when providing patients with fact-based insights and advice?
