Artificial intelligence may reduce the need for glioma brain cancer patients to have biopsies to determine the best treatment for their tumors, researchers report.

Currently, it's common to remove glioma samples from patients and analyze them to select appropriate therapy.

But scientists have been testing imaging techniques that might be used instead of biopsies to assess gl...

A new study casts doubt on claims that artificial intelligence (AI) equals or surpasses the ability of human experts to interpret medical images.

Many previous studies were of poor quality and may have exaggerated the benefits of AI, which could pose a risk to the safety of millions of patients, the study authors claimed.

The investigators reviewed two randomized clinical tr...

There's been a large decrease in Americans' exposure to medical radiation, according to a new study.

Between 2006 and 2016, medical radiation exposure among U.S. patients fell by 20%, reversing a steep, quarter century-long rise.

The number of diagnostic and interventional radiology exams remained largely unchanged, even though the U.S. population jumped about 23 million...

Low-dose chest CT scans don't appear to damage human DNA, a new study shows.

The U.S.-based National Lung Screening Trial, conducted between 2002 and 2010 and involving more than 53,000 heavy and former smokers, revealed that these chest scans can significantly cut lung cancer deaths compared to chest X-rays. They do so by finding cancers at an earlier stage, researchers explained.

U.S. researchers report they have spotted early, subtle signs in the lungs that point to coronavirus infection.

This could help doctors diagnose patients in the early stages of the disease, when it may not be obvious on lung scans, according to the Mount Sinai Health System doctors.

They say they're the first U.S. experts to analyze chest CT scans of 94 patients in China wit...

A new Dutch study is being hailed as proof of the need for annual CT screenings of former and current longtime smokers to reduce deaths from lung cancer.

Dr. Debra Dyer, a spokeswoman for the American College of Radiology and chair of radiology at National Jewish Health in Denver, called the findings "wonderful news."

"There's no doubt about the effectiveness" of annual CT ...

Combining an imaging technology with a new drug that "lights up" lung cancer cells may help surgeons spot hidden bits of cancer, a new study suggests.

The small, preliminary study found that the new combo -- dubbed intraoperative molecular imaging (IMI) -- helped improve outcomes in surgeries of 1 out of 4 patients.

The drug used in IMI is called OTL38. The drug isn't yet ...

More Americans are surviving lung cancer in recent years, but very few people at high risk are getting the recommended screening.

Those are the highlights from the latest "State of Lung Cancer" report from the American Lung Association (ALA), published Nov. 13.

There are positive trends, including the survival numbers: Compared with a decade ago, the five-year survival rate ...

Could a person's risk for lung cancer someday be determined with a quick swab of the nose?

If the preliminary findings of a new study are any indication, it's a distinct possibility.

The experimental nasal swab relies on the fact that most lung cancer patients are current and former smokers. It's meant to be a noninvasive means of separating high-risk patients from low-risk ...

CT lung cancer screening can detect other serious smoking-related conditions, such as heart disease, osteoporosis and emphysema, researchers say.

Medical experts consider lung cancer screening an effective way to detect malignant tumors at earlier, more treatable stages. Now, new research suggests low-dose CT scans of the lungs could also improve diagnosis and treatment of other smoki...

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, overdiagnosis, anxiety and radiation exposure that...

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 research scientist at Kaiser Permanente North...

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 treatment through screening with low-dose c...

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 in the new study, investigators were able to re...

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, researchers found.

It should be poss...

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 found.

It was also twice what Amer...

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 suicide for any one concussion patient rema...

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 involved in language processing.

T...
