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.

ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.
Medicare opts not to make CT radiation-related quality measure mandatory in 2027
The measure evaluates the proportion of scans that exceed certain thresholds for image noise or radiation dose across 18 categories.
Emphysema on baseline lung cancer CT a sign of future mortality risk
“Lung cancer screening shouldn’t just be looking for nodules. That’s a small part of what we see on the CT scan.”
FDA clears GE Revolution Vibe CT scanner aimed at rapidly growing CCTA market
“FDA clearance comes at the perfect time, with guidelines being adopted clinically for cardiac CT and with positive reimbursement driving procedure growth," says Jean-Luc Procaccini, CEO, molecular imaging and CT.
How to address CCTA staffing shortages
Jaime Warren, EdD, FACC, vice president of care transformation at MedAxiom, an ACC company, explains what is needed to address staffing shortages created by a 94% increase in cardiac CT volumes over the past 5 years.

VIDEO: The many benefits of spectral CT for cardiovascular imaging

Suhny Abbara, MD, editor of Radiology: Cardiothoracic Imaging and chief of cardiothoracic imaging for University of Texas Southwestern Medical Center, discusses how spectral computed tomography (CT) can help both cardiac and general CT imaging.

Neuroimaging recedes behind other cost compilers in stroke care

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.

What factors influence low follow-up adherence after a positive LDCT cancer screening?

Experts are calling for strategies to improve follow-up adherence among individuals who have positive lung cancer screenings after a new analysis revealed low rates of compliance.

New DL model detects effects of long COVID using only x-rays

The model could be beneficial for long COVID patients in areas where CT scans are not readily available, researchers concluded.

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.
