PCCT visualizes pulmonary embolism at reduced radiation dose
Photon-counting CT (PCCT) effectively visualizes pulmonary embolism (PE) and reduces radiation dose by 48% compared with traditional CT, according to research presented November 27 at the RSNA meeting. "[PCCT] ensures confident depiction of acute PE with spectral imaging available at low radiation dose in all patient categories," said presenter Martine Remy-Jardin, MD, PhD, of the University Centre of Lille in France. Remy-Jardin and colleagues conducted a study that compared performance of traditional CT to PCCT for diagnosing acute PE. The research included a group of patients referred for suspicion of acute pulmonary ...

Racial disparities found in outpatient imaging for cognitive impairment
CHICAGO – Black patients receive fewer MRI scans for Alzheimer’s disease diagnosis and undergo imaging at an older age than other racial groups, according to research presented November 27 at RSNA 2023. Out of 1,699 people who underwent outpatient imaging to assess cognitive impairment at Boston Medical Center, Black patients were less likely to undergo MRI than CT and were significantly older than white and Hispanic patients at the time of imaging, according to presenter Joshua Wibecan, MD.“If disparity in obtaining access to neuroimaging is one possible barrier that delays diagnosis, it is important to identify thi...

Noninvasive cardiac imaging tests lead to lower downstream costs
Noninvasive cardiac imaging tests lead to reduced downstream costs, and stress echocardiography may be the go-to modality with this in mind, according to Canadian research published November 14 in the Journal of the American Society of Echocardiography. A team led by Idan Roifman MD, from the University of Toronto found that stress echocardiography led to an 18% reduction in costs, while cardiac CT angiography (CCTA) and myocardial perfusion imaging led to the highest downstream costs. “These findings may help inform testing decisions in chest pain patients,” Roifman and colleagues wrote. Previous reports indicate...

Synthetic CTA images from deep-learning model close to real thing
A generative adversarial network (GAN)-based noncontrast CT angiography (CTA) system has promise in vascular diagnosis, suggest research findings published November 14 in Radiology. A team led by Jinhao Lyu, MD, from the Chinese PLA General Hospital in Beijing found that the synthetic images produced by their system were comparable to real CTA images, which could help assess the aorta and carotid arteries while avoiding risks related to contrast media use. “With further studies and assessment, this model may provide a fast and low-cost auxiliary CTA-like imaging method for patients, especially those with iodine allergy...
