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.

Does Ja Morant have lung cancer? Recently, the Memphis Grizzlies star's health status has become a heated topic, with many speculating whether he has lung cancer. This all started with unfounded rumors on TikTok that suggested that he was diagnosed with lung cancer. This alarmed many fans.

Fact Check: Does Ja Morant Have Lung Cancer?

The lung cancer rumors were sparked by a fake video, which was posted by a user named Templex. The video features a fraudulent tweet by Morant's father that claimed that Morant would have to miss an entire season due to lung cancer diagnosis. The tweet also referenced a Bible verse.

The video garnered over 10,000 views and got nearly 4k likes. The misinformation is what led to the fans believing that he had cancer. However, the creator later expressed doubts about the authenticity of the claims. While some prayed for his recovery, other criticized Templex for spreading false information.

Another doctored screenshot of the tweet from January 26 read: "Just got the toughest news of my life, lung cancer. I won't be playing this season, but I am trusting God through it all". It also features a verse from Psalm 28:7. However, no such tweet was posted on X when Health and Me checked Morant's X account. This further confirms that the news is not authentic.

While Morant does not have lung cancer, as no verified sources have confirmed the news and the creator himself too questioned the authenticity of the video. Morant did undergo health checks due to his ulnar collateral ligament injury to his left elbow during a game against the Atlanta Hawks. The Grizzlies later said, on January 24, that he is expected to make a full recovery and will be re-evaluated in about three weeks.

Before that, Morant had missed six straight games with a right calf contusion. Altogether, he has been unavailable for 25 of the team’s 45 games this season, leaving many fans frustrated as they wait to see him back on the court.

What Is Lung Cancer?

Lung cancer is a malignant growth that begins in the tissues of the lungs, usually from DNA damage in the cells lining the airways, which then grow uncontrollably to form tumors. Smoking is a major contributor, but other factors such as exposure to radon, asbestos, or inherited genetic conditions can also play a role.

Symptoms often include a persistent cough, chest pain, and difficulty breathing. Lung cancer is mainly classified into two types: Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC), according to the Cleveland Clinic.

Types Of Lung Cancer

Although many cancers can develop in the lungs, the term “lung cancer” usually refers to two main types: non-small cell and small cell lung cancer.

Non-Small Cell Lung Cancer (NSCLC)

NSCLC is the most common form, accounting for more than 80% of lung cancer cases. Common subtypes include adenocarcinoma and squamous cell carcinoma, while adenosquamous carcinoma and sarcomatoid carcinoma are less frequent forms of NSCLC.

Small Cell Lung Cancer (SCLC)

SCLC tends to grow more quickly and is more challenging to treat than NSCLC. It is often detected as a small tumor that has already spread to other areas of the body. Types of SCLC include small cell carcinoma (also known as oat cell carcinoma) and combined small cell carcinoma.

Nipah virus outbreak in India is now being monitored by Australia too. On Friday, Australia's health minister said that the government is closely monitoring the outbreak of the Nipah virus in Asia. In an interview with Nine Network television, Mark Butler, Minister for Health, Disability and Ageing of Australia, said that the Nipah virus has never been detected in Australia. However, the authorities were taking the threat posed by an outbreak in India very seriously. India confirmed two cases of Nipah virus, both in nurses, in December 2025.

The Indian authorities tell us they've got that outbreak under control, but nonetheless, we're monitoring it very, very closely, because this is a very serious virus," he said.

In Indonesia too, authorities on Thursday implemented stricter monitoring for international passengers at I Gusti Ngurah Rai International Airport in Bali. This is the most popular overseas destination for Australian travelers.

What Is Nipah Virus?

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.

Nipah Virus Symptoms

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain and severe weakness

Nipah Virus Outbreak In India: Travel Restrictions

After two cases were reported in India's West Bengal, concerns have sparked in many parts of Asia, and measures at airports have been tightened.

• Thailand has begun screening passengers at three airports that handle flights from West Bengal.
• Nepal has also stepped up checks, screening arrivals at Kathmandu airport as well as at several land border crossings with India.

The World Health Organization has declared it is unlikely India's deadly Nipah Virus outbreak will cross borders and reach other nations, noting that countries do not need to set any travel restrictions in place.

In an email to Reuters, officials said: "The WHO considers the risk of further spread of infection from these two cases is low". adding that India has the capacity to contain such outbreaks.

"There is no evidence yet of increased human to human transmission," it said, adding that it has coordinated with Indian health authorities.

Earlier this month, two hospital nurses at AIIMS, Kolkata, had tested positive for the infection and were quarantined, prompting widespread testing. As of January 30, five cases, including a doctor and a staff member, were confirmed and nearly 100 people have been quarantined.

While health officials state it is nearly impossible for the virus to transmit across countries and unlikely to cause an international outbreak, countries including Australia, Vietnam, Thailand, Malaysia and Singapore continue to remain on high alert and have begun airport screenings.

Nipah Virus: What Is It And What Are Its Symptoms?

According to WHO, Nipah virus is a zoonotic illness which means it is mostly transmitted from animals to humans through bats. However, it can also spread through fruits that have been contaminated by the saliva, urine or droppings of infected bats. Human-to-human transmission can also occur through close contact with an infected person or their bodily fluids.

The illness has a 75 percent fatality rate and there are no vaccines to protect the public.

The virus was first identified in 1998 during an outbreak among pig farmers in Malaysia and soon made its way to India and Bangladesh in 2001 with cases often involving family members or caregivers tending to infected patient.

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. Some of its common symptoms include:

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain and severe weakness

In 2018, another outbreak occurred in Kerala, India, where 23 confirmed and suspected cases were reported. The virus spread across three hospitals, with both primary and secondary infections traced back to one initial patient.

Samples collected from the patient’s home and workplaces, including pets and partially eaten fruits dropped by bats, all tested negative for the virus, and the exact source of the infection could not be identified.

What Do Doctors Say?

Experts are now cautioning people against the zoonotic nature of the viral infection. Rajeev Jayavedan, the former president of the Indian Medical Association, Cochin, told The Independent, that infection among humans are rare and caused by the accidental spillover due to the human-bat interface, which means consumption of fruits that may have been infected by bats.

“This is more likely in rural and forest-adjacent areas where agricultural practices increase contact between humans and fruit bats searching for food,” he said.

Health and Me previously reported on how doctors are now advising people to be cautious while eating food. Speaking to TOI, Dr Aishwarya R, Consultant, Infectious Diseases at Aster RV Hospital advised people against eating certain food, including fruits fallen from trees, unpasteurized date palm sap and any other fruits without washing.

The doctor explained that this infection can spread with an infected animal which could bite fruits and spread the virus through their saliva.
