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.

‘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.

Over half of emergency CT requests are considered 'inadequate'

Up to 72% of CT requisitions from ED providers could be considered inadequate according to RI-RADS, which was developed to evaluate the clinical reasoning quality of imaging orders.

Research highlights rampant 'over-scanning' during pediatric CT exams

Experts involved in the study caution that this increases children’s risk of developing radiation-induced malignancies down the road.

How one hospital more than doubled its lung cancer screening rate

It is estimated that less than 20% of eligible patients in the U.S. adhere to LCS recommendations, despite numerous studies highlighting the exam’s effectiveness.

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.
