Since its introduction in the 1970s, computed tomography has been a mainstay of radiology. Its overlay-free representation of body structures and the rapid availability of images make CT indispensable in the diagnostic assessment of numerous diseases, especially in emergency medicine. Modern CT systems not only offer innovative procedures for better image quality, but also reduce radiation exposure.
While screening programs for several of the commonest cancers are now well established, lung cancer screening has yet to reach anywhere near the same proportion of at-risk patients.
AI can use data from low-dose CT scans of the lungs to improve risk prediction for death from lung cancer, cardiovascular disease and other causes, a new study finds.
Photon-counting CT allows for a comprehensive, simultaneous evaluation of lung structure and function, something not possible with standard CT, according to a new study.
Should radiation dose from previous medical imaging be considered when a new scan is made? UK experts issued a joint position statement that favors clinical need over prior exposures.
New research shows how AI can be used to fuse images from clinical X-ray CT and MRI scans to allow a clearer and more clinically useful interpretation of the images.
Photon-counting CT enables accurate diagnosis of coronary artery disease in high-risk patients, a potentially significant benefit for people previously ineligible for noninvasive screening.
Iodinated contrast media (ICM) enhance CT imaging, but its single-dose packaging is increasingly proving at odds with modern, more sustainable imaging practices. New award-winning research by a radiology resident and faculty members at Vanderbilt University Medical Center in Nashville, Tennessee, proposes a promising alternative: A switch from using single-dose injectable contrast media kits to…
Transient ischemic attack (TIA) emergency department (ED) encounters with incomplete neurovascular imaging were associated with higher odds of subsequent stroke within 90 days, a new study finds.
A new advanced form of CT imaging offers better cardiovascular imaging quality compared to dual-source CT (DSCT) in infants with suspected cardiac heart defects, according to a new study.
When is a CT scan justified, i.e. when do the benefits of a CT scan for the patient outweigh possible risks associated with radiation? Justification has been a major issue among radiologists ever since CT has become widely available and widely used. With regard to dose the answer is the well-known ALARA principle: “As low as reasonable achievable“. Now, the European coordinated action on…
Dunlee unveiled its new oncology bundles onsite at ECR. The bundles combine components that have been tested and verified to work together so clinicians can offer state-of-the-art onboard Cone Beam CT (CBCT) in facilities.
It’s clear that radiology is lacking in the “green” department: healthcare still causes a large share of global greenhouse gas (GHG) emissions, not least due to diagnostic imaging. Dr Sarah Sheard from Imperial College Healthcare, UK, invited her ECR audience to take a closer look at radiology’s climate footprint – and revealed ways to make the field more sustainable.
Radiology practitioners have highlighted the benefits of cone beam CT in delivering high resolution at a low dose. Delegates at ECR 2023 in Vienna heard how cone beam CT (CBCT) could replace multidetector CT (MDCT) in some areas and is already showing cost-effectiveness benefits.
According to an accepted manuscript published in the American Journal of Roentgenology (AJR), using a dual-source CT (DSCT) scanner for coronary CTA can facilitate clinical processes by eliminating the need to administer beta-blockers for heart rate control while decreasing nondiagnostic examinations.
Radiation exposure in diagnostic and interventional radiology is steadily being reduced, but some important parameters have hardly been taken into account so far, says Dr Kerstin Jungnickel. The medical physics expert explains how patient-specific protocols can improve radiation protection and outlined new findings on the radiosensitivity of certain body regions and their impact.
The Accutron CT-D Vision is the next generation of the leading contrast agent injector for computed tomography from Medtron AG. Focusing on the needs of the user, the latest development stage of the Accutron CT-D improves the usability of the CT double-piston contrast agent injector and optimizes its integration into the radiological environment.
At the ECR 2023 congress in Vienna, Austria, Fujifilm Europe will unveil new products, host an MRI symposium, and provide opportunities to meet the company's experts.
Researchers developed a radiomics model that uses information from coronary CT angiography images to assess coronary plaque vulnerability, a common cause of heart attacks.
Philips is an active participant in the new European Federation for Cancer Images consortium (EUCAIM) – a project launched in the run-up to World Cancer Day 2023.
