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.

Experts call for more judicious use of contrast, highlighting environmental concerns
New data highlight the significant burden contrast media use places on the environment, prompting experts to call for more stringent use of these agents.
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.

New cardiac prevention paradigm explored in TRANSFORM trial using AI and CCTA

Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

New algorithm is twice as accurate at predicting stroke timing compared to the standard of care

Determining stroke onset is critical for management, as there is a small window of time for initiating treatment that can inhibit damage.

New protocol addresses contrast allergies in patients with suspected stroke

In patients with suspected stroke, contrast allergies present a significant dilemma, as contrast-enhanced imaging is often used to guide treatment decisions.

Radiology Partners study unearths 3 common barriers to lung cancer screening

RP affiliate Desert Radiology surveyed 300 screening-eligible patients during their visits, sharing the findings in the journal of Cancer Epidemiology.

Cardiologists to highlight the many benefits of AI-powered CCTA evaluations

Two renowned cardiologists are teaming up to explore the short- and long-term impact of using advanced AI platforms to evaluate coronary CCTA results for signs of coronary artery disease.

Clinical decision support significantly reduces use of CT for pulmonary embolism

Across 340,000 hospital admissions, there was a 7.4% decrease in CTPA use after referrers started consulting CDS, experts write in JACR.

Non-enhancing asymmetries on contrast-enhanced mammography

Is additional imaging necessary for non-enhancing asymmetries on contrast-enhanced mammograms?

Patients with asymmetries on CEM typically are recalled for additional views, ultrasound and occasionally MRI. But the extra workup might not be necessary.
