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.

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.

ED docs overusing CT imaging for gastrointestinal bleeding, study finds

Despite its high accuracy, CTA can come with tradeoffs including requiring radiologists to review a high number of images looking for findings that can be subtle, increasing case complexity and workloads.

80% of requests for emergency head CT inadequate, single-center study finds

Addressing these inappropriate imaging referrals is necessary to reduce healthcare costs, radiation exposure and pollution, experts write in Insights into Imaging.

CT findings linked to dangerous subdural hematoma expansion

If left untreated, SDH expansion puts added pressure on the brain, which can lead to damage, impaired neurological function and even death.
