Finding upends theory about the cerebellum's role in reading and dyslexia

Published: Wed, 09 Oct 2019 13:17:59 EDT

New brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated. The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability, developmental dyslexia, however, this 'cerebellar deficit hypothesis' has always been controversial. The new research shows that the cerebellum is not engaged during reading in typical readers and does not differ in children who have dyslexia.

PET offers more precise screening method to select candidates for radionuclide therapy

Published: Tue, 08 Oct 2019 16:58:23 EDT

PET scanning can offer more precise selection of patients for neuroendocrine tumor therapy, allowing some patients to qualify who would otherwise have been ineligible, according to a new article.

Optical imager poised to improve diagnosis and treatment of dry eye disease

Published: Fri, 04 Oct 2019 15:52:27 EDT

Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is instability in the inner layer of the tear film that protects the outside of the eye.

Pesticides likely caused 'Havana syndrome' that affected Cuba-based diplomats

Published: Thu, 03 Oct 2019 11:17:53 EDT

The study details the nature of the injury, specifies the brain regions involved, including the blood-brain barrier and suggests a possible cause in the form of 'cholinesterase inhibitors,' with 'organophosphorus insecticides' being a likely source. Cholinesterase (ChE) is one of the key enzymes required for the proper functioning of the nervous systems of humans, invertebrates and insects.

How AIDS pathogens multiply in the body

Published: Wed, 02 Oct 2019 14:42:45 EDT

Scientists have now succeeded in using high-resolution imaging to make visible to the millisecond how the HI virus spreads between living cells and which molecules it requires for this purpose. The researchers provide direct proof for the first time that the AIDS pathogen creates a certain lipid environment for replication.

Simple cardiac risk score can predict problems with blood flow in the brain

Published: Mon, 30 Sep 2019 11:48:10 EDT

The study shows that for those participants who do not have a history of heart disease or stroke that a simple cardiac risk score -- a summary measure of factors such as blood pressure, diabetes, smoking, abdominal fat, and dietary factors -- is associated with MRI-detected pre-clinical cerebrovascular disease like carotid artery plaque and silent strokes.

Building a brighter way for capturing cancer during surgery

Bioengineer's smart surgical microscope shows promise for more accurately and quickly identifying cancer cells in the operating room.

Artificial intelligence improves biomedical imaging

Published: Mon, 30 Sep 2019 10:12:59 EDT

Researchers use artificial intelligence to improve quality of images recorded by a relatively new biomedical imaging method. This paves the way towards more accurate diagnosis and cost-effective devices.

Ultrasound can reveal gene expression in the body

Published: Sat, 28 Sep 2019 08:27:37 EDT

Researchers are developing a technique for imaging mammalian gene expression with ultrasound by combining human bacteria and virus DNA.

Trial finds high-dose radiation effective for men whose prostate cancer has spread

Published: Thu, 26 Sep 2019 11:40:00 EDT

A randomized clinical trial of targeted, high-dose radiation for men with oligometastatic prostate cancer has shown the treatment to be an effective and safe option for patients who wish to delay hormone-suppression therapy. The phase II trial found that radiation therapy can generate an immune system response not previously believed possible in this type of cancer.

AI helps scientists predict depression outcomes

Published: Wed, 25 Sep 2019 15:40:35 EDT

Two studies provide evidence for the impact of biology by using artificial intelligence to identify patterns of brain activity that make people less responsive to certain antidepressants. Put simply, scientists showed they can use imaging of a patient's brain to decide whether a medication is likely to be effective.

Blood-brain barrier damage occurs even with mild head trauma

Published: Wed, 25 Sep 2019 13:36:26 EDT

In a new study of adolescent and adult athletes, researchers have found evidence of damage to the brain's protective barrier, without a reported concussion.

Nanotechnology improves chemotherapy delivery

Published: Wed, 25 Sep 2019 13:36:23 EDT

Michigan State University scientists have invented a new way to monitor chemotherapy concentrations, which is more effective in keeping patients' treatments within the crucial therapeutic window.

First systematic review and meta-analysis suggests artificial intelligence may be as effective as health professionals at diagnosing disease

Published: Tue, 24 Sep 2019 22:52:09 EDT

Artificial intelligence (AI) appears to detect diseases from medical imaging with similar levels of accuracy as health-care professionals, according to the first systematic review and meta-analysis, synthesizing the available evidence from the scientific literature.

Machine learning could offer faster, more precise results for cardiac MRI scans

Published: Tue, 24 Sep 2019 08:00:37 EDT

Cardiac MRI scans can be read by AI (artificial intelligence) 186 times faster than humans, with comparable precision to experts. Because the greatest source of measurement errors are human factors, AI has the potential to improve future clinical decision making.

Mummy study: Heart disease was bigger issue for human ancestors than initially thought

Published: Mon, 23 Sep 2019 14:08:01 EDT

A new imaging study of the mummified arteries of people who lived thousands of years ago revealed that their arteries were more clogged than originally thought, according to a proof-of-concept study.

Fast MRIs offer alternative to CT scans for pediatric head injuries

Published: Wed, 18 Sep 2019 13:14:59 EDT

Researchers have released a study that shows that a new imaging method 'fast MRI' is effective in identifying traumatic brain injuries in children, and can avoid exposure to ionizing radiation and anesthesia.
