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...

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...

WEDNESDAY, July 24, 2019 (HealthDay News) -- Use of risky CT scans during pregnancy has risen significantly in North America in the past two decades, a new study finds.

"It's important to quantify exposure to ionizing radiation because it can cause cancer and birth defects, and should be kept to a minimum, especially during pregnancy," said co-lead author Marilyn Kwan. She's a senior ...

MONDAY, July 15, 2019 (HealthDay News) -- A newer form of lung cancer screening may mean fewer deaths from the disease, a new study contends.

Using low-dose computed tomography (LDCT) instead of X-rays helped reduce lung cancer deaths in current and former smokers, the study authors said.

"Lung cancer is the leading cause of cancer death worldwide, and early detection and t...

TUESDAY, April 2, 2019 (HealthDay News) -- Advances in chemotherapy and cancer monitoring can dramatically extend the lives of almost one-third of pancreatic cancer patients with tumors previously considered inoperable, researchers report.

It's good news for patients with a particularly deadly form of cancer that's been highlighted by the recent diagnosis of "Jeopardy!" host Alex Tre...

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...
