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.

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.
FDA clears AI solution for identifying large vessel occlusions on CTA
If left untreated, LVOs can cause ischemic strokes. The algorithm has the potential to significantly reduce time to treatment in these emergency scenarios.
Beyond just nodules—model uses all low-dose CT data to make long-term lung cancer risk predictions
New findings published in RSNA's Radiology highlight the shortcomings of using nodule characteristics and patient history alone to predict an individual’s true cancer risk.
‘Direct-to-patient’ digital prompt boosts CT lung cancer screening uptake
Researchers with two academic health systems recently tried a new approach to increase LDCT uptake, reaching patients electronically outside of a regular appointment and asking them to request a screening.

Hemp and other plant-based compounds could be future of contrast-enhanced imaging

Experts are working to develop agents they say can enhance imaging studies without the risks associated with traditional contrast media.

State law change allows technologists to administer contrast under remote supervision

The update eliminates the requirement for a physician to be on-site and now allows techs to perform venipuncture and conduct contrast administration under remote supervision.

James Muller, MD, explains advances in vulnerable plaque imaging aim to predict and prevent heart attacks.

Advances in imaging could help predict, prevent heart attacks

Imagers can now identify vulnerable plaques that were once very challenging to find. The next steps include improving the screening process and determining which lesions need to be treated right away.

Using chest X-rays for triage could reduce lung cancer overdiagnoses

Chest X-rays could be the key to mitigating the issue of overdiagnosis in certain patient populations undergoing lung cancer screening, according to new research.

Lack of standardized PSMA PET/CT reporting hindering patient care

A new assessment details numerous discrepancies between scoring systems, which could have a detrimental impact on patient care, experts contend.

Tips for preventing 'unpredictable' hypersensitivity contrast reactions

Experts recently developed a new set of recommendations to help providers better navigate decisions related to contrast administration, sharing their guidance in Insights into Imaging.

Deep learning automates head CT reformatting, bolstering workflow efficiencies

Manual processes for generating reformats are susceptible to variability, due to factors such as patient positioning, comfort and individual technologist preferences.

Jaime Warren, EdD, MBA, BHS, CNMT, NCT, FACC, vice president, care transformation, MedAxiom, an ACC company, explains some of the things centers should be thinking about when creating or expanding cardiac CT angiography (CCTA) programs.

How to take your CCTA program to the next level

Changing society guidelines and insurance policies have resulted in more interest in CCTA. To help your CCTA program expand, one expert told Cardiovascular Business, it is important to remember the close relationship between cardiology and radiology.
