Temporal artery ultrasound in the real-time diagnosis of stroke of the eye

For most of us, the phrase "stroke of the eye" sounds like a metaphor. But for UK HealthCare's Jagannadha "Jay" Avasarala, M.D., Ph.D., it's a literal and urgent diagnosis—one that could mean the difference between sight ...

Neuroscience

New brain atlas offers unprecedented detail in MRI scans

A new AI-assisted brain atlas that can help visualize the human brain in unprecedented detail has been developed by UCL researchers, in a major step forward for neuroscience and neuroimaging.

Neuroscience

Highly sensitive imaging technique detects myelin damage

The breakdown of myelin, the insulating layer around brain cells that supports brain function, is prevalent in a range of neurodegenerative diseases, aging and because of various forms of trauma. While electron microscopy ...

Radiation therapy for patients with breast cancer

Radiation therapy is a common component of breast cancer treatment for patients. The high-powered beams of intense energy kill cancer cells and reduce the risk of the cancer recurring.

New imaging technique maps drug movement through skin in minutes

By combining mass spectrometry imaging with an automated analysis tool, researchers from Hebrew University have developed a technique that maps medication distribution across skin layers without dyes or labels. Tested on ...

Ultrasound probe can image an entire organ in 4D

For the first time, a team of Inserm researchers from the Physics for Medicine Institute (Inserm/ESPCI Paris-PSL/CNRS) has succeeded in mapping the blood flow of an entire organ in animals (heart, kidney and liver) with great ...

AI tool identifies women at high risk of interval breast cancer

In a study of more than 100,000 screening mammograms, researchers demonstrated the potential of an AI tool to help identify women at higher risk of developing interval breast cancer, which is breast cancer that is diagnosed ...

Dense breasts: What it means and what women can do about screening

About half of women over 40 have dense breasts. The denser the breast tissue, the more difficult it is to spot cancer on a standard mammogram. Having dense breast tissue can make it harder to detect cancer and sometimes leads ...

Neuroscience

'Kiss-shrink-run' mechanism resolves neurotransmission mystery

A research team has resolved a 50-year-old controversy in neuroscience. By employing a self-developed, time-resolved cryo-electron tomography (cryo-ET) technique, the team, led by Prof. Bi Guo-Qiang from the University of ...

AI helps radiologists spot more lesions in mammograms

Artificial intelligence (AI) improves breast cancer detection accuracy for radiologists when reading screening mammograms, helping them devote more of their attention to suspicious areas, according to a study published in ...

Health

Survey finds some confusion over mammogram guidelines

Mammograms can find cancer early before symptoms appear. Regular screening decreases the risk of dying from breast cancer. But a recent survey question by the Annenberg Public Policy Center shows that some Americans appear ...

AI performs virtual tissue staining at super-resolution

Traditional histopathology, crucial for disease diagnosis, relies on chemically staining tissue samples to highlight cellular structures for microscopic examination by pathologists. This labor-intensive "histochemical staining" ...

Breast cancer incidence trends vary by age

Breast cancer incidence trends differ by age, even among older women, particularly by race and ethnicity and stage at diagnosis, according to a study published online June 24 in JAMA Network Open.

AI matches doctors in mapping lung tumors for radiation therapy

In radiation therapy, precision can save lives. Oncologists must carefully map the size and location of a tumor before delivering high-dose radiation to destroy cancer cells while sparing healthy tissue. But this process, ...

Dual wavefront correction enhances quality of deep-tissue imaging

Wavefront shaping is a promising approach to deep tissue imaging. Until now, it was possible only via an invasive approach: fluorescent points were manually inserted into the sample, and the tissue was indirectly mapped by ...

Removing out-of-pocket fee improves access to 3D mammography

A new study by UCLA researchers shows that removing a modest $45 out-of-pocket fee significantly improved access to digital breast tomosynthesis (3D mammography), an advanced breast cancer screening technology. Researchers ...

Neuroscience

New instrument for enhanced imaging of nerve fibers in the brain

In order to understand the structure and functioning of the brain, neuroscientists need to study the complex, three-dimensional pathways and connections of nerve fibers. The intersection of multiple nerve fibers poses a particular ...
