Low-dose CT chest scans could help detect pneumonia in at-risk patients while exposing them to only small amounts of radiation, a new study has found. The research, published in Radiology: Cardiothoracic Imaging, shows that ultra-low-dose scans can effectively detect pneumonia in patients with compromised immune systems, enabling doctors to treat the infection before it becomes life-threatening. According to the researchers, these scans expose patients to just 2% of the radiation dose used in a standard CT scan.
"This study paves the way for safer, AI-driven imaging that reduces radiation exposure while preserving diagnostic accuracy,” lead researcher Dr Maximiliano Klug, a radiologist with the Sheba Medical Center in Ramat Gan, Israel, said in a news release. He added that CT scans are the gold standard for detecting pneumonia but there are concerns regarding the risk posed by repeated exposure to radiation. There is a solution- ultra-low-dose CT scan. However, the problem is that these scans can be grainy and hard to read, researchers said.
Study Gives Solution To This
To overcome that, Klug's team developed an AI program that could help "de-noise" low-dose scans, making them sharper and easier to read. Between September 2020 and December 2022, 54 patients with compromised immune systems who had fevers underwent a pair of chest CT scans -- a normal dose scan and an ultra-low-dose scan. The AI program cleaned up the low-dose scan, and then both sets of images were given to a pair of radiologists for assessment. Radiologists had 100% accuracy in detecting pneumonia and other lung problems with the AI-cleaned low-dose scans, but 91% to 98% accuracy in examining the scans that hadn’t been improved through AI, results show.
"This pilot study identified infection with a fraction of the radiation dose," Klug said. "This approach could drive larger studies and ultimately reshape clinical guidelines, making denoised ultra-low dose CT the new standard for young immunocompromised patients.
How Can You Detect Pneumonia?
Pneumonia is a lung infection that causes the air sacs in the lungs to fill with fluid or pus and can be caused by bacteria, viruses, or fungi. The symptoms can range from milk to severe, which includes:
Coughing with or without cough
Fever
Chills
Trouble breathing
Chest pain, especially when breathing deeply or coughing
Sweating or chills
Rapid heart rate
Loss of appetite
Bluish skin, lips, and nails
Confusion.
How to detect Pneumonia in coughing newborns and toddlers?
Pneumonia can severely affect newborns and young children as their lungs are comparatively more sensitive. As per Dr Goyal, young children can cough for various reasons including seasonal infections and tonsillitis, which is very common in this age group. But if they look visibly irritable and have poor sleep patterns, then parents must reach out to an expert. "I am not saying that parents must visit a hospital but any local paediatrician would be able to detect pneumonia in your kid.

Michigan, the hardest-hit state in the ongoing nationwide cyclosporiasis outbreak, has reported nearly 10,000 cases of the intestinal illness, which can cause severe, often "explosive," diarrhea, according to state health officials.
So far, the state has recorded 160 hospitalizations, with no deaths reported.
According to the US Centers for Disease Control and Prevention (CDC), 6,707 laboratory-confirmed domestic cases of cyclosporiasis have been reported since May 1.
The agency also said it is tracking more than 11,500 additional suspected cases that have not yet been laboratory confirmed or remain under investigation. Many of these reports have come from Michigan and Ohio.
A US Food and Drug Administration (FDA) investigation has linked part of the outbreak to iceberg lettuce served at Taco Bell restaurants and supplied through Taylor Farms operations in central Mexico.
The FDA is continuing to investigate other potential sources of contamination. Taco Bell has stopped serving the affected lettuce, while Taylor Farms has voluntarily recalled dozens of iceberg lettuce products distributed across 27 states. The company also said it will no longer source iceberg lettuce from central Mexico for the remainder of the growing season.
The recalled lettuce has been linked to illnesses in five states—Indiana, Kentucky, Michigan, Ohio, and West Virginia. However, investigators have not yet determined how many illnesses are directly connected to the recalled products.
Separately, the FDA is investigating another Cyclospora outbreak that is unrelated to the lettuce-linked cases. The second outbreak has sickened 72 people and has been traced to an unidentified food item. The agency said the source has "not yet been identified."
Former CDC Director Robert Redfield told media that the US government may consider ending produce sourcing from central Mexico. He also suggested the outbreak may involve more than lettuce.
Officials are also investigating whether parsley and cilantro, in addition to lettuce, could be associated with the outbreak. The investigation is ongoing.
The FDA advises consumers to check salad and lettuce products purchased during the past week to determine whether they were sourced from Taylor Farms de Mexico in Guanajuato, Mexico.
The recalled retail products include:
Consumers who purchased these products should throw them away or return them to the store where they were bought.
An additional 33 recalled lettuce products were distributed to restaurants and other food-service businesses and are unlikely to be found in home refrigerators. A complete list of recalled products is available on the FDA website.
At this time, no other lettuce varieties—including romaine or butter lettuce—have been linked to the outbreak, even if distributed by Taylor Farms. The company told Newsweek that, aside from the recalled iceberg lettuce, "no other Taylor Fresh Foods products across the country are impacted."

The Donald Trump administration plans to end Medicare Part D premium subsidies after 2026, ending a program that has helped keep prescription drug plan premiums stable, according to the Centers for Medicare & Medicaid Services (CMS).
The decision could affect millions of Americans, particularly those aged 65 and older, who may face higher prescription drug costs beginning next year.
The CMS said its review of insurers' 2027 bids found that health plans now have sufficient experience to accurately price Medicare Part D plans without government support, according to The Wall Street Journal.
The program, to end after 2026, provides insurance companies with an estimated $3.6 billion in subsidies this year to limit premium increases for Part D plans.
"We are stabilizing the market so this bailout is no longer needed. Premiums will go up by less than $10 for most Medicare recipients, with many even seeing lower premiums," CMS Administrator Dr. Mehmet Oz said in a post on X.
"Every Medicare beneficiary still has access to low-cost plans, and we will continue to lower prescription drug prices for every American patient, from more MFN deals to our policy giving seniors access to GLP-1s for $50 a month,” he added.
Around 25 million Americans enrolled in traditional Medicare have stand-alone Part D prescription drug plans, paying an average monthly premium of $36, according to KFF.
Another 31 million beneficiaries receive prescription drug coverage through Medicare Advantage, the privately managed alternative for people aged 65 and older.
The previous Biden administration had introduced the subsidy program ahead of the 2024 presidential election to offset policy changes that would have sharply increased Medicare Part D premiums in 2025.
Dr Oz said that the Biden administration’s approach was “unacceptable” and that it “gave BILLIONS of taxpayer money DIRECTLY to Big Insurance Companies.”
However, it remains unclear how many beneficiaries will pay more or how large those increases will be. Premiums vary by plan, and beneficiaries will have an opportunity to compare and switch coverage during this fall's enrollment period. CMS said premiums for individual plans will be released in September.
AHIP, a major trade group representing health insurers, said it is reviewing the announcement, the New York Times reported.
“At a time of sharply rising prescription drug costs, health plans are focused on keeping Part D coverage and benefits as affordable as possible,” said Chris Bond, a spokesman, in a statement.
A Trump administration official told Bloomberg that the majority of older Americans will see no increase in premiums or may even pay less.
CMS also released preliminary information on 2027 Medicare drug plan bids. The national average monthly bid amount, used to calculate government subsidies for plans, will be $296.05 in 2027.
The agency said the national base beneficiary premium for Medicare Part D will be $41.33 next year. Annual increases will remain capped at 6% through 2029 under provisions of the Inflation Reduction Act.

More than six years after the COVID-19 pandemic devastated the world, newly released personal journals of former National Institute of Allergy and Infectious Diseases (NIAID) Director Dr. Anthony Fauci are giving a raw glimpse into the behind-the-scenes discussions, scientific uncertainty, and political tensions that clouded United States' pandemic response.
The 1,141-page collection, released by Senator Rand Paul ahead of Fauci's scheduled Senate testimony, chronicles events from December 2019 through December 2022.
Announcing the release of Fauci's journals, Sen. Rand Paul said, "The American people deserve the truth about what happened during the COVID-19 pandemic. Dr. Fauci's own contemporaneous writings provide an unprecedented window into the decisions, discussions, and uncertainties that shaped the federal response."
The journals have reignited debate over the origins of SARS-CoV-2 and Fauci's role during one of the most challenging public health crises of recent times.
However, experts say that the diaries represent Fauci's personal contemporaneous notes and do not conclusively establish the origin of COVID-19.
One of the biggest revelations is that Anthony Fauci recorded discussions in late January 2020 in which several scientists raised questions about whether SARS-CoV-2 could have originated from a laboratory because of certain genetic features.
The diary shows these possibilities were discussed internally before scientists later concluded that natural spillover was the more likely. The diary does not provide proof that the virus leaked from a lab.
Fauci wrote, "The first infection was in early December and was not connected to the market... Now we know the market was not the source, it was the amplifier. Having said that, somewhere the virus jumped from animals to humans."

The entries reveal Fauci continued receiving updates about the virus's origin while publicly emphasizing the available scientific evidence supporting natural emergence.
After a conference call with leading virologists, Fauci wrote that several experts discussed whether part of the virus genome could have evolved naturally. He listed the participants and summarized the debate over the possibility of a laboratory origin.
Early diary entries describe the outbreak as looking similar to "bad influenza" before severe complications became clear. This reflects the limited knowledge available in January and early February 2020.
Fauci's notes reportedly show he was conflicted about balancing infection control against the educational and mental health consequences of prolonged school closures, highlighting the uncertainty policymakers faced.
The diary documents Fauci's concerns about bureaucratic delays, operational problems, and disagreements within the federal government during the early COVID-19 response, suggesting these challenges complicated public health decision-making.
The entries describe Fauci's dynamic with President Donald Trump, disagreements over masks, hydroxychloroquine, and public messaging, and concerns about how politics affected science.
He wrote, "AMAZING interaction with POTUS... It was a disturbingly rambling discussion since he kept talking about TV ratings, and HC (Hydroxychloroquine), and influenza and virtually everything else as I was trying to keep him on track."
He also wrote about outshining President Trump. "Apparently the WH is very upset that I am being profiled and it looks like I am putting down the POTUS and becoming a star that outshines him. ... Very stressful!!"
He also wrote that Trump praised him. "As usual, POTUS was very warm and friendly with me... 'I love you, Tony. I feel like giving you a big hug.'"
The journals reveal Fauci's obsession with his fame due to widespread media coverage and his efforts to maintain public trust. He wrote, "For better or worse, I am becoming an international celebrity. Calls from all over the world."
He added, "WH press conference picked up by many outlets. Many print profiles and features on me. Ridiculous, too numerous to count! ... Press is going wild with me."
Fauci's diary sparked a lot of responses from politicians and health experts.
He said, "He lied about masks. He lied about social distancing. He lied about transmission. He lied about natural immunity. He lied about the vaccine's capacity to prevent infection."
He added. "Dr. Fauci did incalculable damage to public health and to the public's trust in government. "He prioritized getting on TV over protecting public health."
