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.

Pharmacies across Britain are reporting serious shortages of a widely used medication, raising concerns that patients could face a higher risk of heart attacks and strokes. Pharmacists have described the situation as “madness,” warning that current NHS prescribing rules are stopping them from switching patients to suitable blood-thinning alternatives when aspirin is unavailable.
While aspirin is commonly taken as a pain reliever, it is also prescribed as a blood thinner. Around one-third of women and nearly 45 percent of men over the age of 65 rely on it as part of their daily medication routine.
A new survey conducted by the National Pharmacy Association (NPA), involving 540 community pharmacies across the UK, found that 86 percent are currently unable to supply aspirin. The shortage appears to be most severe for the low-dose 75mg tablets, although pharmacists report that all strengths are affected. Several pharmacies have also stopped selling aspirin over the counter due to limited stock.
As per The Independent, Olivier Picard, chair of the NPA, said pharmacists are deeply concerned about their inability to order sufficient supplies and the impact this could have on patients who depend on the drug. Low-dose aspirin, particularly the 75mg dose, is commonly prescribed for its antiplatelet effect, which helps prevent the formation of blood clots and lowers the risk of heart attacks and strokes.
Doctors often prescribe aspirin to people who have previously suffered a heart attack or stroke, experienced a transient ischaemic attack, or have conditions such as angina or peripheral arterial disease (PAD). It may also be recommended after certain types of surgery to reduce the risk of clotting.
The NPA is urging the government to reform prescribing regulations that currently prevent pharmacists from offering safe alternatives when the prescribed medicine is unavailable. Mr Picard said pharmacists have long argued for the ability to make appropriate substitutions in these situations.
He added that forcing patients to return to their GP for a revised prescription when an alternative drug is already available is not only frustrating but potentially dangerous. Delays or interruptions in treatment could lead patients to miss vital medication, increasing risks to their health.
In response to the ongoing issue, the Government has added aspirin to its export ban list in an attempt to safeguard supplies for patients in the UK.
The NPA also said pharmacists have been forced to tightly ration the remaining stock, prioritising patients with the most urgent heart conditions or those requiring emergency prescriptions.
According to the Independent Pharmacies Association, international manufacturing delays and wider supply chain disruptions are key reasons behind the shortage. The organisation also pointed to low prices negotiated by the NHS, which can make the UK a lower priority for pharmaceutical manufacturers when stock is limited.
Dr Leyla Hannbeck, chief executive of the Independent Pharmacies Association, said it is deeply concerning to see shortages affecting essential medicines such as aspirin and blood pressure treatments. She explained that while manufacturing delays play a role, pharmacies are also struggling because they cannot order the quantities they need.
She added that low reimbursement rates mean manufacturers often prioritise other countries, leaving the UK at the back of the queue. In the meantime, patients affected by shortages are advised to speak to their local pharmacist, who can offer guidance on suitable alternatives where available.
The shortage has also led to sharp price increases in pharmacies that have managed to secure supplies. The NPA said the cost of a packet of 75mg dispersible aspirin tablets has risen from 18p earlier last year to £3.90 this month.
However, the NHS reimbursement rate remains at £2.18 per packet, meaning pharmacies lose an average of £1.72 every time the medication is dispensed. Mr Picard said this is yet another sign of a pharmacy contract system that urgently needs reform.

Actor Shreyas Talpade recalls that during a shoot for Single Salma in Lucknow, he felt unusually drained after an intense action sequence. In an interview with the Times of India, he revealed, along with the fatigue, there was an odd sensation in his throat, something he had never experienced before. He sat down briefly, brushed it aside, and convinced himself that he was fine.
Yet, something did not sit right with him. Concerned, Shreyas decided to consult a doctor. He underwent an ECG and a 2D echo, and both reports came back normal. While he did not completely ignore what his body was telling him, he also did not probe further. He assumed the medical reports meant there was nothing to worry about.
Months later, in December 2023, Shreyas Talpade suffered a major cardiac episode, an experience that would alter his life in ways he never imagined.
Shreyas was only in his mid-40s when the incident occurred, but it changed him both physically and emotionally.
Physically, he now follows lifelong precautions to ensure such an episode does not recur. Regular medication, scheduled follow-ups, routine checkups, and strict adherence to medical advice have become a permanent part of his life.
Emotionally, the impact was even more intense. Shreyas points out that he had none of the four common risk factors associated with heart attacks. He did not smoke or drink. He was neither diabetic nor hypertensive. And yet, the cardiac episode happened.
Shreyas believes that while life brings uncertainty, many aspects of health remain within our control. After an experience like his, priorities naturally shift. Family becomes the top priority, and staying healthy becomes essential to spend meaningful time with loved ones. That, he says, means sleeping well, exercising four to five times a week, and eating nutritious meals on time.
He stresses that while nutritious food is important, eating at regular times is even more critical. Maintaining fixed meal schedules helps the body function better. Having dinner early allows the digestive system enough time to rest. Even the healthiest food, he notes, loses its benefit if meal timings are irregular.
His earlier discipline with clean eating and regular workouts played a significant role in his recovery. Shreyas also believes that post-pandemic health changes and the Covid vaccine may have triggered complications, but his active lifestyle helped him bounce back faster.
According to him, proper nutrition, regular exercise, quality sleep, and balance strengthen the body. Without these habits, the outcome could have been very different. He firmly believes the body responds to the care it receives.
Shreyas acknowledges that stress is an unavoidable part of life. However, he believes learning how to manage it is essential.
Over time, he has realised that not everything lies within one’s control. Letting go of what cannot be changed is just as important as addressing what can be managed. Wisdom often comes with age, but when someone shares their experiences, he feels it is important to listen.
His message is clear: do not wait for a personal crisis to learn lessons the hard way.

The United States under President Donald Trump’s administration has completed its withdrawal from the World Health Organization (WHO). The US Department of Health and Human Services confirmed the news on Thursday. This has been a longstanding goal of President Trump.
During Trump’s first term, he tried to leave WHO, then gave a notice through an executive order on the first day of his second term. It noted that the US would leave the organization. As per law, the US must give WHO a one-year notice and pay all outstanding fees before its departure. This means the US still owes WHO roughly $260 million. However, legal experts said that US is unlikely to pay up and WHO will have little recourse.
Dr. Lawrence Gostin, an expert on global health law and public health at Georgetown University told CNN, “As a matter of law, it is very clear that the United States cannot officially withdraw from WHO unless it pays its outstanding financial obligations. But WHO has no power to force the US to pay what it owes.”
WHO could pass a resolution saying that US cannot withdraw until it pays, however, it won’t risk creating any further tension that there already is.
The HHS on Thursday confirmed that all US government funding to WHO has been terminated and all personnel and contractors assigned or embedded within the organization have been recalled. It also said the US had ceased official participation in WHO-sponsored committees, leadership bodies, governance structures and technical working groups.
The US government has said it is moving ahead with its decision to exit the World Health Organization (WHO), arguing that the country has not received enough value for the money, staff, and support it has given to the global health body over the years.
Senior officials from HHS said the WHO acted against US interests, especially during the Covid-19 pandemic. They accused the organization of delaying the declaration of a global public health emergency and of praising China’s early response despite signs of underreporting, information suppression, and delays in confirming human-to-human transmission.
HHS also criticized the WHO for being slow to acknowledge airborne spread of Covid-19 and for downplaying the role of people without symptoms in spreading the virus. According to officials, these missteps cost the world precious time as the virus spread rapidly.
While the US has been the WHO’s largest funder, officials pointed out that no American has ever served as the organization’s director-general. “A promise made and a promise kept,” one senior official said, adding that US health policies should not be shaped by “unaccountable foreign bureaucrats.”
That said, the administration has not completely ruled out cooperation with the WHO. When asked whether the US would take part in an upcoming WHO meeting on next year’s flu vaccine composition, officials said discussions are still ongoing.
The government has insisted that leaving the WHO does not mean stepping away from global health leadership. Instead, the US plans to work directly with individual countries, health ministries, non-governmental organizations, and religious groups on disease surveillance and data sharing. This effort is expected to be led by the US Centers for Disease Control and Prevention’s Global Health Center. Officials have promised more announcements on this strategy in the coming months.
However, many public health experts are deeply concerned. Some warn that replacing the WHO with country-by-country agreements will create a fragmented system that lacks coordination and adequate funding. Former CDC officials note that the CDC has staff in about 60 countries, far fewer than the global reach of the WHO.
Critics say the move could leave both the US and the world vulnerable to future outbreaks. Experts argue that infectious diseases do not respect borders and that global cooperation is essential for early detection, data sharing, and rapid response.
Several health leaders have called the decision dangerous and short-sighted, warning that without WHO membership, the US could lose timely access to critical data, virus samples, and genomic information needed to develop vaccines and treatments. WHO’s director-general has described the US withdrawal as a “lose-lose” situation, saying both America and the rest of the world stand to suffer.
