First-in-human-photon-counting-in-coronary-ct-angiography

2022 21 Feb

A recent study led by French researchers examined the benefits of combining a photon counting CT system (PCCT) with coronary CT angiography in diagnosing coronary heart disease. The U.S. FDA approved the first photon counting CT for clinical use back in September 2021. Photon counting CT represents a technological leap beyond previous generation...Read more

2017 19 Jun

Analysis of results from the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial showed that the presence and extent of coronary artery disease detected by CT angiography better predicts the risk for future cardiac events as compared to other measures such as exercise tolerance or restricted blood flow to the heart muscle....Read more

Although pulmonary CT angiography (CTA) is increasingly used to evaluate patients believed to suffer from pulmonary embolism (PE), the diagnostic yield remains low, according to a review published in American Journal of Roentgenology. The finding suggests a potential benefit to the use of clinical decision tools in the diagnostic work-up of suspected...Read more

Noninvasive-imaging-helps-predict-heart-attacks

2017 14 Mar

A new study in the journal Radiology demonstrates the effectiveness of using noninvasive CT angiography and stress tests to detect which patients are likely to suffer a heart attack or other adverse cardiovascular event. This noninvasive approach may be a better option than coronary angiography, an invasive technique, in identifying such high-risk...Read more

A CTA scan (a scan of the arteries) can be performed with a contrast medium volume reduction of up to 75 percent and up to 50 percent reduction in radiation dose, according to a new study from the University of Twente in Enschede, Netherlands. Researchers say the study's results can almost directly be applied in hospitals today, thus providing enormous...Read more

2014 04 Nov

A new study has found a close association between high-risk coronary artery plaque and non-alcoholic fatty liver disease (NAFLD), a common liver disease. Both conditions were detected with a single CT examination, according to researchers who used coronary computed tomography angiography (CCTA) for the study. Previous research has shown that CCTA can...Read more

The journal Radiology has published online the findings of a new multicenter study entitled "Coronary Artery Plaque Volume and Obesity in Patients with Diabetes: The Factor-64 Study." which investigates the role of CT in measuring arterial plaque. It appears that computed tomography (CT) angiography imaging of the coronary arteries provides a precise...Read more

Figure 1. Transverse gadolinium-enhanced T1-weighted MR images obtained superior to the carotid artery bifurcation in a 72-year-old man. L = ICA lumen. (a) Low-signal-intensity calcium (arrow) and lipid core (arrowheads) can be seen. (b) Note contouring of the ICA. The outer adventitial wall (red), lipid core (blue), calcification (green), and vessel...Read more

2013 04 Dec

For the first time, researchers have found that the blood vessels in face transplant recipients reorganize themselves, leading to an understanding of the biologic changes that happen after full face transplantation. The results of this study were presented at the annual meeting of the Radiological Society of North America (RSNA). Face transplantation...Read more
