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.

AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
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 proposal eliminates plan 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.

'One-stop-shop' CT stroke protocol reduces scan time, contrast dose and radiation exposure

The protocol integrates CT angiography of the head and neck with the tomography perfusion acquisition, eliminating the need for two separate scans.

American College of Radiology (ACR) CEO Dana H. Smetherman, MD, MPH, MBA, FACR, explains why opportunistic screening is an important AI imaging technology trend radiology practices should be paying attention.

AI opportunistic screening may have tremendous potential to help patients, ACR CEO says

American College of Radiology leader Dana Smetherman, MD, MBA, discusses the new technology trend and why radiologists should be paying attention.

Using high concentration contrast media reduces patients' pain and discomfort during injections

While most safety considerations associated with contrast injections, like hypersensitivity reactions and extravasation, rarely become reality, pain at the injection site is much more common.

Automated CT-derived markers identify those at higher risk of developing diabetes and other conditions

These measures could be utilized as an opportunistic screening tool in individuals who undergo routine health screenings.

Radiology experts recommend routine chest CT as ‘cost free’ method to assess other concerns in certain patients

Lung transplant recipients are at an increased risk of osteoporosis following surgery and already must undergo multiple such scans following the procedure.

Test bolus of diluted contrast optimizes scan timing during CTA

It also reduces iodine uptake and radiation dose in patients, without sacrificing image quality.

Commercially available AI tool detects 76% of PE that rads initially missed on CT

Improving the detection of pulmonary embolism has been a popular target among multiple AI vendors.

COVID-19 survivors with diabetes may require long-term lung monitoring

Three years after recovery, individuals with diabetes had higher incidence of respiratory symptoms, lung abnormalities on CT scans, and problems moving oxygen into the blood.
