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.

Reimbursement for AI-based plaque assessments is improving
A growing number of private insurers are now covering these advanced technologies. Roosha Parikh, MD, told Cardiovascular Business that the hard work of SCCT and other groups has helped make this happen.
AI helps experts 'see' stress on routine CT scans
It has been well established that chronic stress can affect an individual both physically and psychologically but measuring its impact objectively has remained a challenge.
House lawmakers, ACR push bill requiring Medicaid to cover CT lung cancer screenings
U.S. Reps. Kathy Castor, D-Fla., Brian Fitzpatrick, R-Pa., and Debbie Wasserman Schultz, D-Fla., recently reintroduced the Increasing Access to Lung Cancer Screening Act.
Expanding lung cancer screening eligibility criteria could save tens of thousands of lives
“These findings suggest that current screening guidelines miss most patients with lung cancer, and age-based screening could improve detection and cost-effectiveness," experts note.
AI spots more pancreatic cancer than radiologists
The use of artificial intelligence has the potential to significantly improve the diagnosis of pancreatic cancer, new data suggest.

RapidAI's opportunistic aortic management tool earns FDA clearance

FDA clears RapidAI's opportunistic aortic management tool

The solution can assess the aorta on any CT scan that offers visualization of it, including post-treatment and unenhanced noncontrast studies.

New data highlight 'systemic inconsistencies' in documentation of contrast reactions

Although uncommon and typically not life-threatening, hypersensitivity reactions have increased in recent decades alongside the significant rise in CT use.

CT colonography the most cost-effective cancer screening option for many

Findings from the Neiman Health Policy Institute and Northwell Health indicate that CTC is especially beneficial for underserved populations.

AI-enabled coronary plaque quantification outperforms traditional risk scores

Researchers used AI-enabled software developed by Cleerly to evaluate the CCTA results of more than 6,000 patients. The software was consistently effective, identifying patients who may face an increased risk of poor outcomes.

Coronary calcium may predict a patient's risk of dying from noncardiac conditions

Calcium in the coronary arteries is a known cardiac risk factor. However, new data suggest it may actually tell us more about a person's overall health than researchers previously believed.

Carlos Collet, MD, PhD, director, cardiovascular imaging, physiology and translational therapeutics, Cardiovascular Research Foundation, explains how noninvasive coronary CT angiography (CCTA) assessments will play a major role to eliminate invasive diagnostic angiography and to pre-plan percutaneous coronary intervention (PCI) procedures.

CCTA will play an essential role in the cath labs of the future

Noninvasive coronary CT angiography is growing more and more important as time goes on, helping cardiologists make critical treatment decisions. Carlos Collet, MD, PhD, discussed the technique's potential to be a real game-changer for patient care in a new interview.

Significant variability found in pediatric CT imaging interpretations

Such discordance between pediatric and general radiologists could result in care delays and treatment changes.

AI bests radiologists at predicting lung cancer treatment responses

More accurate response assessments could give providers an opportunity to proactively manage treatment decisions in the future.
