Researchers developed an X-ray imaging method capable of revealing hidden features in a single shot. This could advance cancer detection, disease monitoring, security screening and material analysis.
Cardiac imaging is evolving, and new techniques continue to uncover the secrets of the heart for cardiologists who know how to use them. At the ESC 2025 Congress in Madrid, four experts explored cutting-edge developments across different modalities. Ranging from AI-assisted ultrasound image acquisition and accelerated MRI protocols to advanced prognostic tools for CT and nuclear imaging, these…
Pancreatic cystic lesions – indicating an increased risk of pancreatic cancer – are an occasional incidental finding in routine computed tomography (CT) abdominal imaging. New research suggests that the superior image quality of photon-counting CT (PCCT) can help detect more of these lesions. At the RSNA annual meeting, an expert outlined the benefits and limitations of the imaging technique…
New approaches to cardiovascular radiology are evolving to help clinicians gain an increasingly better insight into heart conditions. Latest developments in cardiovascular radiology include myocardial strain imaging, 4D flow and photon-counting CT technology. An ECR 2024 session shone the spotlight on these areas of cardiovascular imaging with expert speakers outlining the pros and cons of each.
Striking the balance between diagnostic efficacy and patient safety remains critical when utilising iodinated contrast media to deliver the best imaging outcomes. While playing a crucial role in diagnosis and treatment of disease, CT expert Efthimios Agadakos believes the medical profession has a duty to do its utmost to minimize patient risk from contrast media.
Higher image quality, better spatial resolution: A new radiology study demonstrates how photon-counting CT imaging can improve evaluation of coronary artery disease.
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.
Photon-counting detector CT reduces the amount of contrast needed for CT angiography (CTA) while maintaining image quality, according to a new study published in Radiology: Cardiothoracic Imaging.
A promising new application for photon-counting CT: The new technology outperforms conventional CT in detecting subtle damage in the lungs of patients with persistent symptoms of Covid-19.
New CT technology paired with artificial intelligence-based noise reduction offers superior detection of bone disease associated with multiple myeloma at lower radiation doses than conventional CT.
Conventional CT imaging has reached its technical limitations: Resolution can only be improved by small margins and dose cannot be reduced significantly: Photon-counting technology enables drastic improvements.
For the Siemens Healthineers team developing new and ever higher performing computed tomographs is daily fare. But when they introduced their most recent CT system an unusual sense of pride was palpable. The photon-counting detector in the new Naeotom Alpha scanner is different from previous models and achieves a level of detail hitherto unknown.
The U.S. Food and Drug Administration (FDA) cleared the first new major technological improvement for Computed Tomography (CT) imaging in nearly a decade. “Computed tomography is an important medical imaging tool that can aid in diagnosing disease, trauma or abnormality; planning and guiding interventional or therapeutic procedures; and monitoring the effectiveness of certain therapies,” said…
To target ionised radiation as precisely as possible, imaging a tumour is vital in radiotherapy planning. ‘Today, imaging is used increasingly during the therapy itself,’ explained Professor Mark Ladd during the 51st annual meeting of the German Society for Medical Physics (DGMP).
"Tomosynthesis is a hot topic in all the companies involved in mammography", Professor Danielsson pointed out. "But whereas they are developing more or less the same thing, Sectra has a totally different concept - photon-counting - a unique technology that, for the first time, processes X-rays one by one."
