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.

GE HealthCare launches new cardiac CT scanner with advanced AI capabilities
GE HealthCare designed the new-look Revolution Vibe CT scanner to help hospitals and health systems embrace CCTA and improve overall efficiency.
Many CT techs unprepared to manage adverse contrast reactions
Though rare, some reactions can be life-threatening, making the understanding of how to appropriately manage them a critical aspect of a technologist's responsibilities.
Percutaneous transthoracic core needle biopsy: 3 factors that influence procedural success
A new analysis in Clinical Radiology is intended to help guide interventional radiologists in their decision-making processes regarding PCNB to reduce the likelihood of diagnostic failure.
New scanners and strategies for the ‘golden age of CCTA’
As coronary CT angiography (CCTA) continues its rapid expansion, scanner vendors are now offering more economical solutions to ensure access to imaging technology beyond premium systems most often only found at flagship hospitals and academic centers. To conquer CCTA’s technical challenges, new technologies and AI are being incorporated into a new scanner to simplify acquisition and consistently improve image quality.
Ultralow-dose CT aids in diagnosing pneumonia among immunocompromised patients
In a prospective study involving 54 adults, ultralow-dose CT, denoised with deep learning, “substantially” cut radiation exposure while accurately detecting pneumonia.

Routine abdominal CTs offer insight into cardiovascular risk

During this year's RSNA meeting, providers were especially interested in how AI applications could enhance opportunistic screening capabilities.

New scoring system accurately predicts coronary risk in women

The system combines findings from SPECT myocardial perfusion imaging with lifestyle and clinical factors to predict risk of major cardiovascular events.

Abnormal CT findings increasingly common among countertop workers

Individuals who work with engineered stone countertops are increasingly being diagnosed with silicosis—a chronic lung condition that is the result of inhaling large amounts of silica dust.

New AI-enabled CT system is officially available in North America

The scanner is equipped with features aimed at addressing some of the biggest pain points of both radiologists and technologists.

Incidental interstitial lung abnormalities largely underreported

Less than half of incidental interstitial lung abnormalities on CT exams are reported

This is despite experts cautioning that these findings should be "systematically and fully assessed" due to their progressive nature.

More than 1/3 of old strokes are incidentally detected on head CT

A new analysis in JACR estimates that spotting the signs of a previously undetected stroke could benefit up to 200,000 people in the United States every year.

Deep learning recons reduce contrast and radiation doses in aortic CTA

Deep learning reconstruction cuts radiation and contrast dose by half in aortic CTA exams

A new analysis in Academic Radiology dives into the importance of finding balance between reducing radiation exposure while maintaining image quality.
