A single-photon emission computerized tomography (SPECT) scan uses a radioactive substance (Techne gas) and a special camera to create lung images. CT-derived functional imaging is a novel image processing method without the need for inhalation of special gas or injection of contrast. This image shows close similarities between areas of lung function obtained on same…
Representative case of the independent internal patient cohort shows a 54-year-old male patient who suffered from an IDH-mutated oligodendroglioma WHO grade 2 that was correctly classified by all algorithms.

Intravascular imaging using neuro optical coherence tomography (nOCT). The nOCT probe is compatible with standard neurovascular microcatheters, integrating with the procedural workflow used in clinical routine. nOCT captures high-resolution three-dimensional optical data sets providing volumetric microscopy of tortuous cerebral arteries, surrounding structures, and therapeutic devices.

The figures depict images of invasive ductal carcinoma, mucinous carcinoma, and papillary carcinoma, respectively. Despite the variations in tissue structures among different tumor types, the activated regions of the model corresponded to the areas of yellow malignant cell aggregation. Scale bar = 100 µm.

Credit: CC0 Public Domain A new study has advanced how heart failure is detected in women—meaning more female patients can be diagnosed and at an earlier stage. Researchers led by teams from the Universities of East Anglia (UEA), Sheffield and Leeds, have been able to fine-tune how magnetic resonance imaging (MRI) is used to detect…
Fat-enlarged axillary nodes on screening mammograms can predict the risk for cardiovascular disease (CVD), according to a study presented at the annual meeting of the American Roentgen Ray Society, held May 5–9 in Boston. Jessica Rubino, M.D., from the Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire, and colleagues used electronic medical record data from…

The study, which is published in the Journal of Orthopaedic Research, was based on the use of radiomics, which unveils imperceptible patterns in…
PET imaging of 124I-αGal-1 predicts ICB therapy. Credit: N Liu and X Yang, et al. Peking University, Beijing, China. The protein galectin-1 (Gal-1) has been identified as a new PET imaging biomarker for immune checkpoint blockade (ICB) therapy, allowing physicians to predict the tumor responses before beginning treatment. Information garnered from Gal-1 PET imaging could…
Credit: MART PRODUCTION from Pexels A dissertation at Umeå University shows that ultrasound can help patients with a type of rheumatic disease to live longer and healthier lives. These patients have so far had an increased risk of cardiovascular disease, which contributes to premature death. Patients with a type of rheumatic disease called radiographic axial…
Dr. Laurie Margolies demonstrates the Koios DS Smart Ultrasound software, Wednesday, May 8, 2024, at Mount Sinai hospital in New York. The breast imaging AI is used to get a second opinion on mammography ultrasounds. “I will tell patients, ‘I looked at it, and the computer looked at it, and we both agree,’” Margolies said….
