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.

In a remarkable emergency response, Dubai paramedics revived a man who collapsed from a heart attack, earning widespread praise on social media.
The man reportedly collapsed suddenly and showed no signs of consciousness or a pulse. People at the scene immediately alerted emergency services, who responded within minutes. The team began cardiopulmonary resuscitation (CPR) using an advanced CPR machine.
A video now going viral on social media shows paramedics arriving within minutes and performing CPR using the LUCAS 3 automatic chest compression device. The machine, which delivers high-quality chest compressions more consistently than manual CPR, helped circulate blood to vital organs and revived the man within minutes.
“Dubai’s emergency response looks like the future: a man collapses from a heart attack, paramedics arrive within minutes, strap on the LUCAS 3 automatic CPR device, and revive him right there,” a social media user wrote.
“If there were a machine like this, it would be a huge help because people wouldn’t have to perform CPR for a long time,” another user added.
The LUCAS 3 chest compression system is a mechanical CPR device originally developed by Swedish startup Jolife AB in collaboration with Norwegian inventor Willy Vistung and cardiologist Stig Steen. The device and company were later acquired by medical technology company Stryker in 2016.
The device is designed to deliver continuous, high-quality chest compressions while reducing physical strain on caregivers.

According to the company, studies have shown that the LUCAS device can improve blood flow to the brain and achieve higher EtCO2 values compared to manual chest compressions. With more than 50,000 devices in use worldwide, including within the Dubai Corporation for Ambulance Services, a patient is reportedly treated using the device approximately every minute, it added.
CPR, or Cardiopulmonary Resuscitation, is an emergency life-saving technique used when a person stops breathing or their heart stops beating. Quick action is critical, as CPR can double or even triple a person’s chances of survival.
Steps to keep in Mind While Giving CPR
Step 1: Check The Surroundings
Ensure the area is safe by checking for dangers such as traffic, fire, or falling objects.
Step 2: Position The Person
Lay the person on their back on a firm surface and open the airway by tilting the head back slightly. Check the mouth for any visible obstruction and remove it carefully if possible.
Step 3: Check Breathing
Listen for breathing sounds for no more than 10 seconds. If the person is not breathing normally, begin CPR immediately.
Step 4: Chest Compressions
Place the heel of one hand at the center of the chest, slightly below the nipple line. Place your other hand on top and interlock your fingers. Keep your elbows straight and push hard and fast — about 2 inches deep — at a rate of 100 to 120 compressions per minute. Allow the chest to rise fully between compressions.
Step 5: Rescue Breaths
After 30 compressions, tilt the person’s head back, lift the chin, pinch the nose shut, and seal your mouth over theirs. Give two rescue breaths, each lasting about one second, while watching for chest rise. If the chest does not rise, reposition the head and try again.
Step 6: Repeat The Cycle
Continue alternating 30 chest compressions with 2 rescue breaths until the person starts breathing or emergency medical professionals arrive.

Excessive screen time use is harming sleep, mental health, learning, and development of children, according to a new advisory by the US surgeon general’s office, which urged parents to limit children’s screen time.
Even as President Donald Trump's nominee for surgeon general awaits confirmation, the "Harms of Screen Use" bulletin warns that children and teens are spending more time on their digital devices than on sleep or school, the USA Today reported.
It noted that excessive screen use is linked to heavy or compulsive screen use
Health and Human Services Secretary Robert F. Kennedy Jr. said evidence of risks to children’s physical and mental health is “mounting,” even though screens can also provide some benefits.
The advisory promotes the slogan “Live real life,” encouraging children and families to replace excessive screen use with in-person activities and healthier routines.
Alongside the report, the officials also released a toolkit recommending steps for parents, schools, healthcare providers, and policymakers to help reduce screen dependence and encourage safer technology habits among young people.
The advisory also links excessive and "compulsive" screen use to
The report aligns with recent studies, which show how too much screen time affects developing minds.
Recent findings from the All India Institute of Medical Sciences, Delhi, suggest that early digital exposure to children before the age of one increases the baby's risk of autism.
The findings led by the Department of Pediatric Neurology showed that infants exposed to high levels of digital media at around one year of age are significantly more likely to display autistic signs by the time they reach age three.
India has also issued pediatric and education guidelines advising parents to limit screen exposure for young children, though there is no nationwide ban. States like Karnataka and Andhra Pradesh have also taken up action against social media use and screen time.
While countries are not fully “banning” screen time, several of them have introduced restrictions, guidelines, or proposed laws aimed at reducing children’s screen time, especially around smartphones and social media in schools.

India has successfully linked the health records of more than 100 crore people with Ayushman Bharat Health Accounts (ABHA) under the Ayushman Bharat Digital Mission (ABDM), the Ministry of Health and Family Welfare said today.
Implemented by the National Health Authority, the milestone marks a major step towards building an integrated, citizen-centric, and interoperable digital healthcare ecosystem in the country.
“The linking of over 100 crore health records with ABHA is an important milestone in the journey of Ayushman Bharat Digital Mission. ABHA-linked health records empower citizens with secure and consent-based access to their health information and support continuity of care across the healthcare ecosystem,” said Dr. Sunil Kumar Barnwal, CEO, NHA.
According to the Ministry, more than 450 public and private health technology solutions have integrated with the ABDM ecosystem, enabling digitisation and seamless exchange of health records across healthcare facilities.
The ministry said ABDM doubled the number of linked health records from 50 crore in February 2025 to over 100 crore in just 15 months.
Nearly 10 crore health records are now being linked every two to three months. From fewer than 1,000 linked records during its initial phase to over 100 crore today, ABDM has evolved into one of the world’s largest digital health ecosystems.
Uttar Pradesh emerged as the leading contributor with over 15.03 crore ABHA-linked health records, followed by Andhra Pradesh with over 11.95 crore linked records.
Bihar, Rajasthan, and Gujarat also recorded major progress by linking over 7.37 crore, 6.32 crore, and 4.77 crore health records, respectively.
Among the major government programs and digital platforms contributing to the milestone are:
Private health technology partners and ABDM-enabled digital solutions have also contributed significantly towards the creation and linkage of ABHA-linked health records.
ABHA is a unique digital health identity that allows citizens to securely link and access their health records across hospitals, clinics, laboratories, and healthcare providers.
Through ABDM’s consent-based health information exchange mechanism, citizens can digitally share their medical records with registered healthcare providers while maintaining the privacy and security of personal health information.
“ABDM is designed to place citizens at the center of the digital health ecosystem. With consent-based sharing of health records, individuals can access their medical information whenever required and share relevant records with healthcare providers digitally. This will help make healthcare delivery more accessible, efficient, and patient-centric,” Barnwal said.
The Ayushman Bharat Digital Mission is creating the digital public infrastructure required for an interoperable healthcare ecosystem through key digital building blocks such as:
With over 100 crore health records now linked with ABHA, ABDM has marked another milestone towards creating longitudinal digital health records for citizens and enabling a more connected, paperless, efficient, and patient-centric healthcare ecosystem in the country.
