MRI and computer modeling reveals how wrist bones move

Published: Wed, 13 Feb 2019 14:57:25 EST

We use our wrists constantly, but how do they work? Researchers have now demonstrated a longtime assumption about individuals' right and left wrists, while also finding differences between wrists of males and females: discoveries that could help inform and guide future treatments.

Light and sound gauge the temperature of deep tissues

Published: Wed, 13 Feb 2019 13:22:02 EST

Biomedical engineers have demonstrated how photoacoustic imaging can take the temperature of deep tissue more quickly and accurately than current techniques. This discovery is expected to play an important role in advancing thermal-based therapies to treat cancer.

Brain clock ticks differently in autism

Published: Wed, 13 Feb 2019 09:08:14 EST

The neural 'time windows' in certain small brain areas contribute to the complex cognitive symptoms of autism, new research suggests. In a brain imaging study of adults, the severity of autistic symptoms was linked to how long these brain areas stored information. The differences in neural timescales may underlie features of autism like hypersensitivity and could be useful as a future diagnostic tool.

PET imaging agent may allow early measurement of efficacy of breast cancer therapy

Published: Mon, 11 Feb 2019 16:39:45 EST

Physicians may soon have a new way to measure the efficacy of hormone therapy for breast cancer patients.

Benefits of delayed cord clamping in healthy babies

Published: Mon, 11 Feb 2019 10:54:02 EST

A five-minute delay in the clamping of healthy infants' umbilical cords results in increased iron stores and brain myelin in areas important for early-life functional development, a new study has found.

MRI cardiac stress test shows promise at identifying fatal heart disease

Published: Fri, 08 Feb 2019 14:21:27 EST

Results from a large, multi-center study suggest that cardiac magnetic resonance, or CMR, has potential as a non-invasive, non-toxic alternative to stress echocardiograms, catheterizations and stress nuclear exams in identifying the severity of coronary artery disease.

New drug brings unexpected hope in targeting cancer cells

Published: Fri, 08 Feb 2019 08:22:00 EST

An unexpected finding in preclinical platelet studies could provide a novel approach to targeting and destroying difficult-to-treat cancer cells, providing new therapeutic options for a range of cancers.

Size and time impact outcomes when mechanical clot removal used for large core strokes

Published: Thu, 07 Feb 2019 17:32:32 EST

Patient outcomes with large core stroke damage are worse the larger the core volume and the longer the time lapse between stroke onset and treatment. Perfusion imaging may help identify large core stroke patients who are potential candidates for mechanical thrombectomy (clot removal).

Researchers develop prostate cancer prediction tool that has unmatched accuracy

Published: Thu, 07 Feb 2019 07:51:24 EST

Researchers have developed a novel machine-learning framework that distinguishes between low- and high-risk prostate cancer with more precision than ever before. The framework is intended to help physicians -- in particular, radiologists -- more accurately identify treatment options for prostate cancer patients, lessening the chance of unnecessary clinical intervention.

New scan technique reveals brain inflammation associated with post-treatment Lyme disease syndrome

Published: Tue, 05 Feb 2019 09:05:33 EST

More than 1 in 10 people successfully treated with antibiotics for Lyme disease go on to develop chronic, sometimes debilitating, and poorly understood symptoms of fatigue and brain fog that may last for years after their initial infection has cleared up.

Scientists shed light on processes behind age-related decline in brain structures

Published: Thu, 31 Jan 2019 10:49:36 EST

Aging can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study.

Going for an MRI scan with tattoos?

Published: Wed, 30 Jan 2019 17:55:59 EST

Tattoos are increasingly popular. Every eighth person in Germany has already felt the sting of getting a tattoo. Yet, if tattooed people are to be examined with magnetic resonance imaging (MRI), the question often arises of how risky the procedure is for them. The first prospective study with statistically verifiable numbers has now been presented by a research team.

Difference in brain connectivity may explain autism spectrum disorder

Published: Wed, 30 Jan 2019 16:16:40 EST

Researchers have identified a possible mechanism of human cognition that underlies autism spectrum disorders, or ASD. They found there was brain overconnectivity in the unimodal-subcortical connections and brain underconnectivity in the supramodal-subcortical connections for ASD individuals, as compared to the typically developing control group, suggesting a relationship between connectivity and the expression of ASD.

What causes aging of the upper lip? Loss of volume, not just 'sagging'

Published: Wed, 30 Jan 2019 13:30:40 EST

Plastic surgeons have long debated the mechanisms aging-related changes in the face: Are they related more to 'deflation' or 'sagging'? A new study helps settle the debate, showing significant loss of volume in the upper lip in older adults.

Combined SPECT and cardiac MR imaging can help guide ventricular tachycardia ablation

Published: Wed, 30 Jan 2019 10:37:42 EST

Adding functional imaging to structural imaging of patients with ventricular tachycardia (VT) has the potential to improve current VT ablation strategies, according to new research.

Researchers ID, treat faulty brain circuitry underlying symptoms of schizophrenia

Published: Wed, 30 Jan 2019 07:58:01 EST

In a first-of-its-kind study, researchers have determined the underlying anatomical cause of certain symptoms of schizophrenia, then ameliorated them with non-invasive brain stimulation. The scientists reported that these symptoms arise from a breakdown in a network between the brain's prefrontal cortex and the cerebellum, and that non-invasive brain stimulation restored network function, which in turn improved schizophrenia's most debilitating symptoms.

New technology gives unprecedented look inside capillaries

Published: Fri, 25 Jan 2019 17:29:33 EST

A team has developed a new tool that images blood flow through capillaries, detecting subtle changes in capillary organization for early diagnosis of disease.

Hyperbaric oxygen therapy for Alzheimer's disease

Researchers have the first PET scan-documented case of improvement in brain metabolism in Alzheimer's disease in a patient treated with hyperbaric oxygen therapy (HBOT).

Artificial intelligence can dramatically cut time needed to process abnormal chest X-rays

Published: Tue, 22 Jan 2019 08:44:01 EST

New research has found that a novel Artificial Intelligence (AI) system can dramatically reduce the time needed to ensure that abnormal chest X-rays with critical findings will receive an expert radiologist opinion sooner, cutting the average delay from 11 days to less than three days. Chest X-rays are routinely performed to diagnose and monitor a wide range of conditions affecting the lungs, heart, bones, and soft tissues.

Pushing the boundaries of 3D microscopy
