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.

Finance Minister Nirmala Sitharaman has announced a surprising tax reduction for India's fishers and marine industry, and experts say it is good news for you too.
Until now, fish caught by Indian vessels beyond territorial waters and brought back to the country for mass consumption has been treated as import, attracting customs duties and integrated goods and services tax (GST).
The combined tax burden raises costs and compliance issues, which discouraged people from deep-sea and exclusive economic zone (EEZ) fishing as well as
However, during her Union Budget 2026 presentation, Sitharaman proposed that fish caught in the EEZ and high seas by Indian fishing vessels are treated as duty-free when brought into Indian ports and treated as exports when landed at foreign ports.
This means that the market availability for Omega-3 packed fishes including salmon, mackerel, tuna, herring and sardines will significantly increase as their existing steep prices see a tremendous fall.
Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.
These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Since many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.
Although the body can convert another type of omega-3, alpha-linolenic acid (ALA), into EPA and DHA, this process is not highly efficient. As a result, fish oil supplements may provide a convenient way to ensure optimal levels of omega-3s.

Some popular sources of Omega-3 include:
EPA and DHA are essential for maintaining brain function throughout life. These fatty acids are abundant in the brain's cell membranes, helping to preserve cell health and facilitate communication between brain cells.
Research has shown that a lack of omega-3 can lead to cognitive impairments. In animal studies, diets deficient in omega-3s resulted in reduced DHA levels in the brain, leading to deficits in learning and memory. In older adults, lower DHA levels have been linked to a smaller brain size, which may indicate accelerated brain ageing.
Maintaining sufficient levels of omega-3s can help support cognitive function and may reduce the risk of age-related brain decline.
The optimal dosage varies, but research suggests that 1,000–2,000 mg of omega-3 fatty acids from fish oil daily is a good starting point. People with depression should look for supplements with higher EPA content. It is pertinent to note that people should consult health experts before starting fish oil supplementation.
These imported, specialized cancer treatments, particularly targeted therapies and monoclonal antibodies, often cost thousands, placing a massive financial burden on patients, leading to lifelong debts.
In this year's Union Budget, Sitharaman also proposed reducing import duty tax on 17 cancer drugs and seven medicines for rare diseases, which will in turn, help patients seek proper care on a timely basis.
Deshmukh commented: "India is witnessing a steady and alarming rise in cancer cases, where late detection, prolonged treatment and high medicine costs often lead to preventable complications and loss of life. Against this backdrop, the Union Budget’s decision to remove customs duty on 17 cancer drugs and 7 medicines for rare diseases stands out as a truly progressive and patient-first measure.
"Affordability remains one of the biggest hurdles in cancer care, forcing many families to delay or discontinue treatment. By reducing import duties, this move has the potential to significantly lower the cost of advanced and targeted therapies, making them accessible to a larger section of patients."

Experts are cautioning US of a potential Nipah virus outbreak, especially through international travels. Countries across Asia have already started airport health screenings. Thailand has geared up as it receives a high number of travelers from Kolkata, where the two cases of Nipah virus were detected.

Dr Krutika Kupalli, a Texas-based expert who formerly also worked with the World Health Organization (WHO), told The Daily Mail that the possibility of Nipah virus outbreak is 'absolutely' something the Centers for Disease Control and Prevention (CDC) should be 'closely monitoring'.
“Nipah virus is a high-consequence pathogen, and even small, apparently contained outbreaks warrant careful surveillance, information sharing, and preparedness. Outbreaks like this also underscore the importance of strong relationships with global partners, particularly the WHO, [which] plays a central role in coordinating outbreak response and sharing timely, on-the-ground information," she said.
A CDC spokesperson told The Daily Mail that the agency is in 'close contact' with authorities in India. "CDC is monitoring the situation and stands ready to assist as needed."
Nipah virus outbreak reported in West Bengal, India started with the cases of two nurses, one of whom has now been discharged.
As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.
In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.
Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.
Nipah virus is infectious and can spread from animals like bats and pigs to humans through bodily fluids or contaminated food. It can also pass between people through close contact, especially in caregiving settings. While it can spread via respiratory droplets in enclosed spaces, it is not considered highly airborne and usually requires close, prolonged contact for transmission. Common routes include direct exposure to infected animals or their fluids, consuming contaminated fruits or date palm sap, and contact with bodily fluids such as saliva, urine, or blood from an infected person.

The American Red Cross reported a severe shortage of blood that has affected Tri-City area hospitals. In the last month, there has been a 35% drop in blood supply. The 'Code Red' blood shortage in Washington created a critical situation with hospitals requesting for blood. The drop is also noted due to the winter weather that has affected donation drive.
Reports note that during the winter season, blood supply becomes challenging, though its demand may increase due to illness and severe weather conditions. However, the same factors lead to fewer donation drives that leads to critical shortage. According to Red Cross reports, more than 550 blood drives have been canceled since January 21. This has resulted in over 15,000 uncollected blood and platelet donation.
The shortage has severely impacted the availability of blood for trauma victims, cancer patients and those who require emergency surgeries. During such situation, volunteer donors play an essential role.
Diana Heilman, supervisor at the Kennewick Red Cross Fixed Site, said, "octors may face difficult decisions during a blood shortage, such as who can safely receive the products and treatments, and they will potentially have to wait because there simply isn't enough blood available."
Type O is a universal donor, while Type O positive is the most commonly transfused blood type. A negative blood type is found in only 6% of the population, and B negative is less than 2%.
Red Cross also announced a $20 e-gift card for those who donate between January 26 to February 28, as incentive.

This is one of the most common concerns, especially among first-time female donors. According to Dr. Sangeeta Pathak, Director and Head of Transfusion Medicine at Max Super Speciality Hospital, Saket, who spoke to Health and Me, as per the Drugs and Cosmetics Act, women are advised not to donate during their menstruation, particularly during the 4-5 days of active bleeding. However, they are completely eligible to donate at any other time of the month if they are in good health.
Health is key when it comes to blood donation. “A person should be completely healthy and free from fever or illness at the time of donation,” says Dr. Pathak. Moreover, certain medications can lead to deferral, and there is a comprehensive list maintained under the Drugs and Cosmetics Act. So if you’re on a prescribed course, it’s best to consult a doctor or the blood bank before donating.
Yes. If you’ve recently had a tattoo or body piercing, you’ll need to wait 12 months before you can donate blood. This is a precautionary step to ensure there’s no risk of transmitting infections.
