CT-FFR imaging assesses adverse outcome risk in angina patients
September 15, 2023 -- CT angiography-derived fractional flow reserve (CT-FFR) imaging helps clinicians assess stable angina patients' adverse outcome risk -- even if they have high coronary artery calcium scores, a Danish research group has found. Read More
Zurich group casts light on contrast use in photon-counting CT
August 2, 2023 -- Photon-counting CT enhances image quality for coronary CT angiography exams while also reducing contrast use by up to 40%, Swiss researchers have stated. The technology's higher contrast-to-noise ratio properties are of particular note, they said. Read More
Dutch group gives boost to heart disease risk assessment
June 29, 2023 -- A vendor-neutral CT coronary artery calcium score calibration tool is showing considerable promise for improving heart disease risk assessment, investigators from the University Medical Center Utrecht in the Netherlands have stated. Read More
German team unveils findings on PCCT use in high-risk cardiac cases
June 26, 2023 -- Photon-counting CT (PCCT) effectively detects heart disease in high-risk patients, offering "significant benefit for people previously ineligible for noninvasive screening," researchers from the University of Freiburg have reported. Read More
Radiography and medical students benefit from VR training
May 31, 2023 -- Most radiography and medical students appreciate the value of virtual reality (VR) simulation-based training to learn about radiation protection in the interventional radiology suite, an Irish research group reported on 25 May in Radiography. Read More
Subclinical atherosclerosis increases heart attack risk 8-fold
April 5, 2023 -- Coronary atherosclerosis -- detected on coronary CT angiography (CCTA) -- increases a person's risk of heart attack eight-fold, Danish authors have stated. The findings sound a warning to clinicians about monitoring patients with poor heart health, they believe. Read More
SPECT comparable to conventional gamma for detecting heart attack
March 17, 2023 -- SPECT cameras with cadmium zinc telluride detectors perform comparably to conventional gamma devices for imaging patients with suspected heart attack, Swedish researchers have reported. Read More
Team Lille reports novel results on dose in photon-counting CT
March 8, 2023 -- The influential research group headed up by Prof. Martine Rémy-Jardin, PhD, of the University Centre of Lille, France, has found that photon-counting CT can reduce radiation dose for coronary CT angiography exams by more than a third compared with dual-source CT. Read More
Researchers sing praises of photon-counting CT at ECR 2023
March 2, 2023 -- VIENNA - Researchers' enthusiasm for photon-counting CT shows no sign of abating, it seems. Several of them shared their latest data about the technology's pros and cons with ever-eager ECR attendees. Read More
Zurich group shares latest experiences of photon-counting CT
January 31, 2023 -- Photon-counting CT reduces the amount of contrast needed for coronary CT angiography by 25% -- without impacting image quality. That's the main finding of a Swiss study published on 26 January in Radiology: Cardiothoracic Imaging. Read More
