AI Tool Accurately and Consistently Classifies Breast Density on Mammograms

Breast density reflects the amount of fibroglandular tissue in the breast commonly seen on mammograms. High breast density is an independent breast cancer risk factor, and its masking effect of underlying lesions. Now, an artificial intelligence (AI) tool can accurately and consistently classify breast density on mammograms. More...

AI-Based Analysis of Expiratory Chest CT Images of Post-COVID Patients Shows Evidence of Small Airways Disease

Early reports indicate that more than 50% of adult survivors of SARS-CoV-2 infection experience post-acute sequelae of COVID-19 (PASC), more commonly known as “long COVID.” Respiratory symptoms, including cough and dyspnea, are reported by nearly 30% of patients with long COVID, including those who experienced mild infection. Now, a new study has found air trapping, indicative of small airways disease, in patients with lingering respiratory symptoms after COVID-19 infection. More...

Novel Micro-Computed Tomography (Micro-CT) Imaging Method Could Significantly Reduce Scan Times

Micro-computed tomography (micro-CT) is an imaging method based on X-ray images which are reconstructed to form a three-dimensional image of the internal structure of samples with small dimensions. Researchers in biomedical physics and biology have significantly improved micro-CT, more specifically imaging with phase contrast and high brilliance X-ray radiation. More...

Mobile CT Scanner with Photon Counting Detector Expands Diagnostic Possibilities at Patient’s Bedside

NeuroLogica Corp. (Danvers, MA, USA), the U.S. healthcare subsidiary of Samsung (Suwon-si, South Korea), has received 510(k) clearance for the addition of Photon Counting Detector (PCD) technology to its state-of-the-art OmniTom Elite CT scanner. With this, NeuroLogica delivers the first FDA 510(k) cleared, single-source photon counting CT scanner with single detector on a mobile system. OmniTom Elite with PCD can generate spectral CT images at multiple energy levels. More...

New Hybrid PET/MRI System Aims to Improve Breast Cancer Diagnosis

The HYPMED project, coordinated by the European Institute for Biomedical imaging (EIBIR, Vienna, Austria), aims to develop a radiofrequency coil that can be connected to any regular clinical MR scanner and transform the device into a high-resolution PET/MRI hybrid system, which can be used to identify even the smallest breast cancer tumors and better characterize the cancer, as well as its response to therapy.

Artificial Intelligence Predicts Treatment Success for Melanoma Patients from Early CT Scans

Artificial intelligence (AI) is poised to revolutionize the field of radiology as a tool to improve disease detection, diagnosis, and clinical care. The technology has the potential to assist clinicians by uncovering hidden information within imaging scans invisible to even the well-trained eye. Now, researchers have demonstrated that applying AI to standard-of-care imaging can help predict how well immunotherapy will work for patients with melanoma. More...

CT as Accurate as Angiography in Detecting Coronary Artery Disease Non-Invasively

A study by researchers from 31 European clinical institutions suggests that cardiac computed tomography (CT) offers a similar level of diagnostic accuracy as catheterization in patients with suspected coronary artery disease (CAD), in addition to being associated with a lower risk of complications.
