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.

3D camera guidance meaningfully aids patient positioning, dose reduction

Regardless of a patient’s body mass index, using a scanner-integrated 3D camera for situating CT patients on the table can optimize not only patient positioning but also radiation dose. 

Rising trauma CT utilization flagged over costs, incidental findings

The increase has been especially evident in single-encounter chest/abdominopelvic scans, not least those performed for minor injuries.

8 trends in radiology technology to watch in 2023

Here is a list of some key trends in radiology technology from our editors based on our coverage of the radiology market.

Paleo-radiologist: ‘I saw the king’s face for the first time’

Thanks to a radiologist equipped with CT and 3D image reconstruction, Pharaoh Amenhotep I is finally getting a proper clinical workup.

Radiology trainees win over trauma surgeons with immediate reads

When trained with high-fidelity simulation, junior radiology residents can master the discipline of reading whole-body CTs right at the trauma scanner—and doing so with high diagnostic accuracy, work speed and interpretive confidence.

M&A mergers and acquisitions business deal

GE HealthCare eyes IR guidance company, releases revenue results

Less than a week after ringing the Nasdaq opening bell to showcase its long-awaited independence, GE HealthCare has announced a first strategic acquisition is in the works.

Mahadevappa Mahesh, PhD, professor of radiology and a medical physicist at the Johns Hopkins University School of Medicine, explains a new American College of Radiology (ACR) effort to ensure that lower radiation dose X-ray images under Image Wisely and As Low as Reasonable Achievable (ALARA) meet diagnostic reading standards. He spoke to Radiology Business at the Radiological Society of North America (RSNA) 2022 meeting.

Trends in the number of radiology studies and a decline in radiation dose

A special report in Radiology offers a rare overview of the number of radiology exams performed each year worldwide and focuses on the decline of associated radiation doses patients receive.

Around the web

The all-in-one Omni Legend PET/CT scanner is now being manufactured in a new production facility in Waukesha, Wisconsin.

After reviewing years of data from its clinic, one institution discovered that issues with implant data integrity frequently put patients at risk. 

Prior to the final proposal’s release, the American College of Radiology reached out to CMS to offer its recommendations on payment rates for five out of the six the new codes.
