Two-photon microscope provides unprecedented brain-imaging ability

Published: Thu, 02 Dec 2021 12:30:08 EST

Advancing our understanding of the human brain will require new insights into how neural circuitry works in mammals, including laboratory mice. These investigations require monitoring brain activity with a microscope that provides resolution high enough to see individual neurons and their neighbors.

Eye imaging technology breaks through skin by crossing beams

Published: Wed, 01 Dec 2021 16:20:33 EST

Biomedical engineers have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The new 'dual-axis' approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

Magnetic resonance imaging (MRI) and artificial intelligence (AI) can detect early signs of tumor cell death after novel therapy

Published: Wed, 01 Dec 2021 15:01:18 EST

A recent study demonstrates that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer therapy.

MRI reveals altered brain structure in fetuses exposed to alcohol

In the first MRI-based study to investigate pre-natal alcohol exposure, researchers found significant changes in the brain structure of fetuses exposed to alcohol compared to healthy controls.

In children with multiple sclerosis, teriflunomide tempers lesion growth

Published: Tue, 30 Nov 2021 17:40:08 EST

A phase 3 clinical trial tested the safety and efficacy of teriflunomide, an oral immunomodulatory drug, in children with multiple sclerosis. Although the medication did not prevent disease relapses to a greater extent than placebo, the option for some patients to switch from placebo to teriflunomide before the end of the trial likely biased the results against treatment efficacy. The drug appeared to reduce the number of new or enlarged lesions that are detected through MRI.

High-speed holography of cells spots physical beacons of disease

Published: Tue, 30 Nov 2021 15:04:47 EST

Biomedical engineers have engineered a holographic system capable of imaging and analyzing tens of thousands of cells per minute to both discover and recognize signs of disease.

Revolution in imaging with neutrons: FRM II research group develops new processing method for image data

Published: Thu, 18 Nov 2021 20:35:55 EST

An international research team has developed a new imaging technology. In the future this technology could not only improve the resolution of neutron measurements by many times but could also reduce radiation exposure during x-ray imaging.

New imaging technology may reduce need for skin biopsies

Published: Thu, 18 Nov 2021 20:30:54 EST

A new 'virtual histology' technology shows promise by analyzing images of suspicious-looking lesions and quickly producing a detailed, microscopic image of the skin, bypassing several standard steps typically used for diagnosis -- including skin biopsy, tissue fixation, processing, sectioning and histochemical staining.

New holographic camera sees the unseen with high precision

Published: Wed, 17 Nov 2021 10:01:06 EST

Northwestern University researchers have invented a new high-resolution camera that can see the unseen -- including around corners and through scattering media, such as skin, fog or potentially even the human skull.

Noninvasive brain biopsy shows improved sensitivity in tumor detection

Published: Fri, 12 Nov 2021 10:05:47 EST

A team of researchers has developed a noninvasive diagnostic method that may one day replace the biopsy with a simple blood test.
