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.

As Bangladesh grapples with a surge in highly infectious measles cases, neighboring Indian states Meghalaya and Tripura are strengthening preventive measures by ramping up vaccination drives and intensifying surveillance, particularly in border districts, to curb any potential spillover and contain the spread of the disease.
As per media reports, Bangladesh is reporting more than 1,100 suspected infections in a single day. The vaccine-preventable measles has also claimed the lives of 98 children in the country’s one of the worst outbreaks.
To strengthen early detection and response in Indo-Bangla border areas, the Meghalaya government conducted an orientation-cum-preparedness meeting last week at the Amlarem Sub-Divisional Office with district administration and health department officials, the Border Security Force, community leaders, and grassroots workers, including ASHAs and Anganwadi workers.
Dr A Khonglah, sub-divisional medical and health officer, Amlarem, informed of a few suspected cases in the state, The Times Of India reported. Khonglah noted there was “no cause for panic”, but stressed that early reporting was critical for timely testing and treatment.
In a notification issued on Monday, Meghalaya’s state health department called for stepping up surveillance in East Khasi Hills District.
“Immediate corrective measures are required in response to ongoing measles outbreaks in Bangladesh and the heightened risk in border districts and blocks. It is imperative to strengthen surveillance, early detection, reporting, and response mechanisms across all sectors in East Khasi Hills District,” the notification said.
The state health department directives include:
Similarly, Health officials in Tripura are also assessing the prevailing measles and rubella situation, with a focus on vaccination coverage and containment measures.
The officials in a review meeting focused on evaluating infection trends, immunization progress, and the effectiveness of ongoing containment strategies, Northeast Today reported.
Mission Director of the National Health Mission (NHM), Saju Vaheed A on Sunday visited Unakoti district to assess the prevailing measles and rubella situation, with a focus on vaccination coverage and containment measures.
The director reviewed data on vaccination coverage and stressed the need for close monitoring of vulnerable areas.

Since the beginning of the year, India is seeing sporadic outbreaks of measles. Madhya Pradesh's Gwalior reported three outbreaks, and Morena six.
Over January and February 2026, 41 children were diagnosed with measles in Tikari village in Madhya Pradesh.
However, swift action by health authorities with proactive frontline engagement and data-driven rapid response prevented an escalation into large measles outbreaks. These sporadic outbreaks also highlighted the critical importance of measles-rubella (MR) vaccination in protecting children and communities.
As per official data, till April 19, Bangladesh recorded 3,443 confirmed measles cases and more than 23,600 suspected infections.
While over 12,000 patients have recovered, the outbreak has resulted in at least 36 confirmed deaths and 181 deaths among suspected cases, MNTV reported.
In response, Bangladesh has vaccinated more than 1.9 million children against measles and rubella in an emergency nationwide campaign.
Health Minister Sardar Md Sakhawat Husain said the situation has begun to stabilize due to early intervention, adding that vaccine supplies remain sufficient to sustain the campaign through June.
Measles is a highly contagious virus that spreads through direct contact or through the air when an infected person coughs or sneezes. It is a vaccine-preventable disease that can cause devastating complications, including blindness, pneumonia, encephalitis, and long-term immune dysfunction.
Symptoms typically appear seven to 14 days after exposure and may include:
To safeguard against measles, individuals should ensure timely vaccination, especially for children.
Maintaining good hygiene, such as frequent handwashing and covering the mouth while coughing or sneezing, helps reduce transmission.
Avoiding close contact with infected individuals and ensuring proper nutrition to boost immunity are also important.
Public awareness and community health programs play a crucial role in prevention.
Mindless use of weight loss drugs can cause the weight to return later. (Photo credit: iStock)
Weight loss drugs appeal to many for their convenience, but according to some experts, there are a number of noteworthy side effects. From rapid weight gain to sagging skin, several side effects of weight loss drugs have been identified through studies. Now, new research has found that weight loss drugs can cause more muscle loss than clinical expectations. The results, presented at the American College of Physicians Internal Medicine (ACP-IM) meeting in San Francisco, add to existing evidence on the possible adverse effects of GLP-1.
When a person loses a considerable amount of weight, they also lose bone mass, muscle mass, and some connective tissue. Experts at the University of North Carolina at Chapel Hill found that no studies directly associate muscle loss with a decline in physical function or strength. However, this clinical gap underscores the need to assess strength and mobility alongside weight loss in patients receiving this therapy. The systematic review identified 36 randomised clinical trials that measured changes in muscle mass and fat among adults using incretin-based obesity medications such as tirzepatide, dulaglutide, or semaglutide.
Each study measured body composition using MRI, CT scans, and bioelectrical impedance analysis. Most of them used DEXA along with other methods to obtain information about lean muscle mass, bone mineral density, and the distribution of body fat. The average age of participants ranged from 20 to 63.7 years. Only four studies included participants aged 60 years and above. None of the studies focused on adults aged 65 years or older.
Researchers noted a concerning trend: patients’ estimated muscle loss exceeded the 25 per cent threshold. Clinicians had expected a 25 per cent reduction, but not more than that. Experts also found that 68 per cent of people who used the drugs exceeded the 25 per cent benchmark, compared to 50 per cent of those who relied on placebos and lifestyle interventions. None of the studies measured whether the loss of muscle mass was correlated with function or strength loss.
Despite being a concerning side effect of weight loss drugs, muscle mass is likely to diminish anyway with age. Additionally, the loss is more significant in older adults. Therefore, doctors advise caution when prescribing these drugs to individuals who are more prone to losing muscle function at an advanced age. Ideally, doctors should recommend exercise or physical therapy to patients taking weight loss medications.
The final word
According to experts, weight loss drugs do have a positive side — and that extends beyond obesity treatment. These drugs are also beneficial for diabetes and help reduce the risk of cardiovascular disease. However, it is important to support treatment with the right kind of diet and a proper exercise regimen. Solely depending on the medication can lead to weight gain once it is discontinued. Therefore, for healthy weight loss, it is best to rely on sustainable methods for long-lasting results.
Sadhguru recommended some tips for sustainable weight loss. (Photo credit: AI generated)
Indian guru and founder of the Isha Foundation, Sadhguru, offers a different perspective on life and mental health. In a 2025 talk, he spoke about weight loss. At a time when obesity, metabolic, and lifestyle disorders are at an all-time high, there is an urgent need to revisit and fix the way one eats. While many turn to diet fads and practise calorie or food group restrictions, Sadhguru recommends the contrary. The 68-year-old emphasises the importance of sustainable weight management through balanced choices, mindful eating and meals aligned with the body’s natural rhythm.
Many people aim to lose weight to deal with body image issues or to prepare for a special upcoming occasion. However, according to Sadhguru, one must not try to force discipline through restriction, but instead allow the body to regulate itself efficiently while maintaining energy levels. If you are looking for foods to include in your diet for sustainable weight loss, here are some recommendations:
