THURSDAY, Aug. 2, 2018 (HealthDay News) -- Heart disease is a leading cause of death in patients with the autoimmune illness lupus. Now, research suggests high-tech scans can spot cardiac issues early.

The scans can detect heart abnormalities even before patients have any symptoms, Chinese researchers say.

"Our findings may affect current lupus diagnostics and treatment -...

TUESDAY, July 17, 2018 (HealthDay News) -- Children with autism show abnormalities in a deep brain circuit that typically makes socializing enjoyable, a new study finds.

Using MRI brain scans, researchers found that kids with autism showed differences in the structure and function of a brain circuit called the mesolimbic reward pathway.

That circuit, located deep within the ...

TUESDAY, May 29, 2018 (HealthDay News) -- Even if you discover that you have the first biological signs of Alzheimer's, you are not doomed to develop the crippling dementia, a new study suggests.

"Just because you have amyloid [proteins] in the brain doesn't mean you're going to get dementia tomorrow. It doesn't mean you're going to get dementia in five years," said lead researcher ...

MONDAY, April 23, 2018 (HealthDay News) -- If you have lung or throat cancer, exactly how you are positioned during your radiation treatments may alter your chances of beating the disease.

New research suggests that even tiny shifts can mean the radiation may harm organs around tumors in the chest, most notably the heart.

"We already know that using imaging can help us to ta...

TUESDAY, Feb. 13, 2018 (HealthDay News) -- Before they go in for an X-ray, CT scan or MRI, patients may have questions about their screening. But new research finds at least one in every five people saying they received no information about their procedures beforehand.

"This is an important finding in today's health care system, where we want more patient engagement and involvement," ...

TUESDAY, Feb. 13, 2018 (HealthDay News) -- Kidney stones are becoming more common, especially in women, new research has found.

Better diagnostic tools could be part of the reason for the steady rise in diagnoses, according to Mayo Clinic researchers.

By using CT scans, "we are now diagnosing symptomatic kidney stones that previously would have gone undiagnosed because they ...

THURSDAY, Feb. 8, 2018 (HealthDay News) -- A long-feared shortage of a substance used in millions of medical imaging procedures each year in the United States appears to have been avoided, federal officials report.

The U.S. Food and Drug Administration announced today that it has approved a new technology to produce the country's own supply of the substance -- a radioisotope called Te...

TUESDAY, Jan. 30, 2018 (HealthDay News) -- You and your friends likely share similar interests. But did you know you could also have similar patterns of brain activity?

Dartmouth College researchers assessed the friendships or social ties within a group of nearly 280 graduate students. Brain scans revealed that friends had the most similar brain-pattern responses to videos. And friend...

WEDNESDAY, Dec. 27, 2017 (HealthDay News) -- Powerful magnetic fields created during an MRI scan were thought to play havoc with some pacemakers, but a new study says these scans are safe for people with the heart devices.

Researchers tested the safety of MRIs on more than 1,500 people who had older pacemakers or implantable defibrillators -- called legacy devices -- that the U.S. Foo...

TUESDAY, Dec. 19, 2017 (HealthDay News) -- The U.S. Food and Drug Administration on Tuesday called for tougher warnings and "additional research" into a dye commonly used with standard MRIs.

The dye -- a "contrast agent" -- contains a metal called gadolinium. It made news recently after claims from actor Chuck Norris that its use during MRI scans seriously affected his wife's brain.<...

WEDNESDAY, Nov. 29, 2017 (HealthDay News) -- Despite recent claims from actor Chuck Norris that a dye commonly used during MRI scans seriously sickened his wife, a new study finds no evidence to support such a link.

The substance in question is gadolinium. It's a metal found in contrast agents that are injected into the body during an MRI scan, to enhance the quality of the images.

THURSDAY, Nov. 2, 2017 (HealthDay News) -- Certain pieces of brain structure may make some people less likely to develop Alzheimer's disease.

That's the conclusion of a new study that could lead to new ways to prevent or slow the memory-destroying disease, researchers said.

For the study, the researchers analyzed brain samples from patients at memory clinics and found that t...

THURSDAY, Aug. 31, 2017 (HealthDay News) -- Eating prompts the brain to release "feel good" hormones, known as endorphins, a new study shows.

Researchers found the regulation of these naturally occurring opioids, which can produce a sense of pleasure or euphoria, may help the body know when it's satisfied. On the flip side, overeating associated with the overstimulation of this system...

WEDNESDAY, Aug. 16, 2017 (HealthDay News) -- If you enjoy expensive wines, keep the findings of new brain research in mind: Your pleasure may have more to do with the price of the vino than its quality.

"The reward and motivation system is activated more significantly with higher prices, and apparently increases the taste experience in this way," said researcher Bernd Weber.

<...

TUESDAY, Aug. 8, 2017 (HealthDay News) -- People with a particular genetic cause of autism show structural abnormalities in the brain that are readily detected with noninvasive imaging, according to a new study.

Using MRI brain scans, researchers found clear brain structure abnormalities in people with autism caused, in part, by defects in chromosome 16.

Those MRI findings w...

WEDNESDAY, Aug. 2, 2017 (HealthDay News) -- Brain injuries among pro football players are in the headlines, but pro fighters often suffer damaging head injuries, too.

Now, research with boxers and mixed martial arts professionals suggests that combination MRI technology can help pinpoint which injuries might lead to brain damage.

In the boxing ring, as on the football field...

WEDNESDAY, July 26, 2017 (HealthDay News) -- Distinguishing Alzheimer's disease from another common form of dementia may get easier using a new, noninvasive technique, researchers say.

While Alzheimer's is the best-known form of dementia, another form of brain deterioration, called frontotemporal dementia (FTD), accounts for 10 percent to 15 percent of dementia cases.

Howeve...

THURSDAY, July 20, 2017 (HealthDay News) -- Sophisticated brain scans might be able to detect consciousness in brain injury patients who appear unconscious in the intensive care unit, a new study says.

"Early detection of consciousness and brain function in the intensive care unit could allow families to make more informed decisions about the care of loved ones," said study co-lead au...

WEDNESDAY, July 12, 2017 (HealthDay News) -- A new CT scan analysis may allow doctors to identify blood vessel inflammation before heart problems actually crop up, researchers report.

Detecting inflammation before it hardens into irreversible plaque could potentially help cardiologists prevent heart attacks, the scientists said.

"Currently, CT only tells you whether there ar...

TUESDAY, July 11, 2017 (HealthDay News) -- People with insurance that covers virtual colonoscopy are nearly 50 percent more likely to get screened for colon cancer, a new study shows.
