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.

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.
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.

David A. Rosman, MD, MBA, deputy chief, radiology enterprise service, Mass General Brigham, explains details of a recent AJR article that showed imaging outside of hospitals could potentially save billions.

Recently the system was struggling to keep some of its CT departments fully staffed, causing delays in care and burdensome workloads for staff.

Charalambos Antoniades, MD, the British Heart Foundation Chair of Cardiovascular Medicine at the University of Oxford, is a co-founder of the company Caristo, which has developed technology to image coronary inflammation on coronary computed tomography angiography (CCTA) scans to visualize a key factor of residual cardiovascular risk.

Detecting coronary inflammation on CT imaging could reshape preventive cardiology

New technology now being considered by the FDA for approval can capture coronary inflammation on CCTA images and provide risk assessments. What could this mean for the future of cardiac care? We spoke to one researcher to learn more.
