Comparing annual emergency department encounters that involved a head CT in 2007 and 2022, researchers noted a 51 percent increase and also found significant disparities in access to head CTs for Black patients, those on Medicaid and patients in rural hospital settings.

Along with the capability of automated measurements and 3D reconstructions of the aorta, Rapid Aortic may facilitate earlier detection of aortic aneurysms and dissections on computed tomography exams.

Photon-counting computed tomography demonstrated over 20 percent accuracy at the patient level and nearly 14 percent higher accuracy level at the vessel level in comparison to energy-integrating detector CT for detecting > 70 percent stenosis, according to a newly published study.

The launch of the AVI imaging platform reportedly facilitates direct integration into PACS and RS systems, and automated access to adjunctive CT-based AI applications for a variety of conditions including pulmonary embolism, intracranial hemorrhage and large vessel occlusion

In a recent interview, Timothy Fairbairn, Ph.D., and Fatima Rodiguez, M.D., discussed new research findings, recently presented at the American Heart Association (AHA) conference, showing the value of AI-powered quantification of plaque burden from CCTA exams for predicting adverse cardiovascular outcomes.

Facilitating timely triage, the qER-CTA software enables AI assessment of the internal carotid artery and M1 segment of the middle cerebral artery for possible large vessel occlusions (LVOs).

Facilitating timely detection and follow-up management of patients with aortic aneurysms, the PRAEVAorta2 software reportedly enables automated measurement of aortic diameters on computed tomography (CT) scans.

In a study involving over 500 patients, researchers noted that the CT-based AI software led to a 24 percent increase of evaluations for aortic abdominal aneurysms within six months of detection.

The AI-powered Bunkerhill MAC software reportedly facilitates chest CT detection and quantification of mitral annular calcification, which has been linked to higher cardiovascular risk and related mortality.

Based on survey findings and subsequent voting from radiologists at nine facilities, the Society of Abdominal Radiology has issued new consensus recommendations on the use of adult abdominal photon-counting CT.
