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...

WEDNESDAY, March 13, 2019 (HealthDay News) -- The term artificial intelligence (AI) might bring to mind robots or self-driving cars. But one group of researchers is using a type of AI to improve lung cancer screening.

Screening is important for early diagnosis and improved survival odds, but the current lung cancer screening method has a 96 percent false positive rate.

But i...

MONDAY, Jan. 7, 2019 (HealthDay News) -- CT scans diagnose many serious conditions and illnesses, but they expose patients to levels of radiation that aren't always consistent and may be harmful, a new study finds.

The large differences in the doses of radiation patients are exposed to appear to be caused by who is doing the scanning and not differences in patients or equipment, resea...

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...

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...

THURSDAY, July 12, 2018 (HealthDay News) -- The underpinnings of autism may lie in an unexpected part of the brain, a small study suggests.

Scientists conducted brain scans on 20 boys with autism and 18 boys without the neurodevelopmental disorder. The scans showed that boys with autism had a significantly flatter surface on the right side of their cerebellum. That side happens to be ...

WEDNESDAY, Feb. 14, 2018 (HealthDay News) -- The first blood test to help diagnose a concussion has been approved by the U.S. Food and Drug Administration.

Known as the Banyan Brain Trauma Indicator, it could help reduce the need for CT scans and thus decrease radiation exposure to patients, according to the FDA.

The blood test checks for levels of specific proteins that hav...

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 ...

WEDNESDAY, Nov. 15, 2017 (HealthDay News) -- ER doctors frequently use pricey but unnecessary tests to determine whether people with chest pain are having a heart attack, a new study reveals.

Results show that patients don't do any better when CT scans or treadmill stress tests are tacked onto the standard battery of diagnostic tests for chest pain patients.

"You don't need ...

THURSDAY, Aug. 31, 2017 (HealthDay News) -- People with no calcium buildup in their arteries seem to have a significantly lower risk of heart attack and stroke, a new study finds.

Calcium collects in the arteries after plaque builds up and hardens over time, the study authors explained.

For the study, researchers looked at nearly 6,200 people, aged 45 to 84, and found that t...

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...
