TUESDAY, Sept. 3, 2019 (HealthDay News) -- Despite efforts from medical groups to cut down on the overuse of CT scans and MRIs for safety reasons, their use has instead increased, a new study shows.

"Medical imaging is an important part of health care and contributes to accurate disease diagnosis and treatment, but it also can lead to patient harms such as incidental findings, overdia...

MONDAY, Aug. 26, 2019 (HealthDay News) -- Silent strokes are common in seniors who have had surgery, and may double their risk of mental decline within a year, a Canadian study reports.

While an obvious (or "overt") stroke often causes symptoms such as weakness in an arm or speech problems, a silent (or "covert") stroke is apparent only on brain scans.

The new study included...

TUESDAY, Aug. 20, 2019 (HealthDay News) -- A concerning number of U.S. women are exposed to the MRI contrast agent gadolinium early in pregnancy, a new study reveals.

In many cases, this exposure occurs before women know they're pregnant.

The researchers said their findings underscore the need for effective pregnancy screening measures before using gadolinium, which can cros...

TUESDAY, Aug. 13, 2019 (HealthDay News) -- "Smoldering" spots in the brains of multiple sclerosis patients may signal more aggressive and disabling forms of the disease, researchers report.

Their finding may help test the effectiveness of new treatments for these types of MS.

The investigators used specialized brain scans to examine the brains of hundreds of MS patients and ...

TUESDAY, July 23, 2019 (HealthDay News) -- Nearly three years ago, U.S. diplomats in Cuba began experiencing hearing loss, dizziness and memory problems -- in what the Trump administration attributed to an attack of unknown origin.

Now researchers say they have detected some "alterations" in the patients' brain structure and function -- though the significance, if any, is disputed.

TUESDAY, June 4, 2019 (HealthDay News) -- Breast MRI screening is a good way to detect small tumors, but it's unclear how much it benefits women with a history of breast cancer, a new study finds.

Right now, experts recommend that breast cancer survivors have yearly mammograms to help catch any recurrences early. An unresolved question is whether adding breast MRI to that screening is...

WEDNESDAY, Feb. 13, 2019 (HealthDay News) -- If you have tattoos, it's probably safe to get an MRI scan, European researchers say.

While millions of people with tattoos have MRIs every year without side effects, some adverse reactions have been reported. Researchers said there had been no systematic studies of how safe it is for people with tattoos to have an MRI.

Reported s...

MONDAY, Jan. 7, 2019 (HealthDay News) -- Higher costs, not better patient care, explain why the United States spends much more on health care than other developed countries, a new study indicates.

U.S. health care spending was $9,892 per person in 2016. That was about 25 percent more than second-place Switzerland's $7,919 and more than twice as high as Canada's $4,753, researchers fou...

WEDNESDAY, Dec. 5, 2018 (HealthDay News) -- Ultrasounds and MRIs during pregnancy and after birth can detect most Zika-related brain abnormalities in infants, researchers report.

If a woman is infected with the Zika virus during pregnancy, her child can be born with microcephaly and other severe brain defects, the U.S. Centers for Disease Control and Prevention says.

The new...

MONDAY, Nov. 12, 2018 (HealthDay News) -- People who have experienced either a concussion or a mild traumatic brain injury are twice as likely to commit suicide than others, a new review suggests.

The analysis also indicates that men and women who have had a concussion are also more likely to consider or attempt suicide.

The investigators stressed that the absolute risk of s...

TUESDAY, July 17, 2018 (HealthDay News) -- People with multiple sclerosis (MS) often live with uncertainty because it's hard to predict how quickly the disease will progress and how disabling it might become.

But researchers hope a new MRI test that tracks iron levels in the brain will help answer those questions.

The test -- called quantitative susceptibility mapping (QSM)...

THURSDAY, May 17, 2018 (HealthDay News) -- A new MRI scanning technique can help doctors better nail down when a person has suffered a stroke and whether clot-busting drugs will help preserve their brain.

This technique could save the brains of some people who suffer "wake-up" strokes, where symptoms become apparent after they wake from a night's sleep, said lead researcher Dr. Gotz T...

TUESDAY, Feb. 20, 2018 (HealthDay News) -- A new type of MRI (magnetic resonance imaging) that doesn't use a contrast agent appears better at detecting what's really cancer and what's likely just a harmless lesion, researchers report.

In a study in Germany, the new technique reduced false-positive findings by 70 percent. The scan was also able to detect 98 percent of breast cancers c...

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," ...

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...

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, Oct. 26, 2017 (HealthDay News) -- Knowing they're at increased risk for breast cancer isn't enough to persuade many women to get MRI screenings -- even if they're free.

Researchers studied more than 1,000 women in a U.S. military health system who had a 20 percent or greater lifetime risk of breast cancer due to genetics or personal or family history.

Between 2015 ...

FRIDAY, Sept. 1, 2017 (HealthDay News) -- Babies who receive general anesthesia for surgery before they're 1 year old may have less white matter in their brains, a small study suggests.

The researchers said they also found that the integrity, or structure, of the white matter might have been affected.

White matter is tissue that connects different parts of the brain.

THURSDAY, Aug. 31, 2017 (HealthDay News) -- How come some people can just walk on by a plate of freshly baked chocolate chip cookies, while others grab a handful as they pass?

Brain scans done on teenagers may provide a clue. Researchers found that the brains of overweight teens were less active in areas that help with impulse control when teens were shown pictures of food.
