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.

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.
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.

overnight night shift attending radiologist burnout

Diagnostic errors occur mostly when radiologists exceed their average daily production

It may be necessary to monitor physicians' average daily productivity numbers over more extended periods of time to address this issue.

Walgreens-backed VillageMD launches ‘major imaging hub’ open 7 days a week

The “first imaging department of its kind” will deliver CT, ultrasound, X-ray, fluoroscopy and ambient MRI, all in one location.

Rethinking ICM storage could help imaging departments reduce waste by 59%

“While drug pricing is not opaque and absolute costs of medications can vary widely, any waste comes at a cost," researchers wrote in a new analysis.

Use of advanced imaging skyrockets in ED, and radiologists should be ready for more

The surge in imaging utilization is independent of increased patient volumes, “suggesting that other extrinsic drivers” contributed, researchers noted.
