(Press-News.org) SINGAPORE – Researchers from the Agency for Science, Technology and Research (A*STAR) and the National Healthcare Group (NHG) have jointly pioneered an innovative imaging technique combining Multispectral Optoacoustic Tomography (MSOT) with artificial intelligence (AI) that could significantly improve the diagnosis and treatment of basal cell carcinoma (BCC), the most common form of skin cancer worldwide.
This advanced technique uses photoacoustic imaging (PAI), enhanced by an automated segmentation algorithm, to provide real-time, high-resolution, three-dimensional (3D) images of skin tumours. By accurately mapping tumour boundaries, the technology helps doctors plan surgeries with greater precision, reducing the risk of repeat procedures and improving patient outcomes. Details of the technology and its early testing have been published in the peer-reviewed European Journal of Nuclear Medicine and Molecular Imaging.
Revolutionising Skin Cancer Care in Singapore
BCC is the most common type of skin cancer globally, with rising numbers reported in Singapore, particularly among the nation’s ageing population. Existing diagnostic methods, such as biopsy and Mohs micrographic surgery (MMS), can be uncomfortable and prolonged, often requiring multiple procedures to confirm the extent of the tumour and ensure complete removal.
To address these challenges, through a first-in-human clinical study, scientists from A*STAR Skin Research Labs (A*STAR SRL) and NHG’s National Skin Centre (NSC) have developed a new approach that combines an advanced segmentation algorithm with PAI. By automatically identifying the precise shape and size of skin tumours, the AI-powered system reduces the need for manual interpretation and speeds up the diagnostic process.
This advanced imaging technology captures detailed 3D views of tumours, including measurements of width, depth and volume, while reaching deeper layers of skin than conventional tools. By providing clearer insights into tumour boundaries, the system supports more accurate surgical planning, helping to minimise repeat surgeries and improve recovery experiences for patients.
Promising Early Results and Future Potential
The technology is currently being tested at NSC, where eight patients have participated in a pilot study. In these cases, MSOT was used to scan tumours before surgery, with early findings closely matching results from the diagnostic methods currently used to confirm skin cancer.
“Early results have been very promising, showing strong alignment with existing diagnostic methods. We are now focused on bringing this technology closer to real-world clinical use to benefit skin cancer patients,” said Prof Malini Olivo, Distinguished Principal Scientist who, with Assoc Prof Dinish U. S, Principal Investigator at A*STAR SRL are co-authors of the study.
While the current study focuses on basal cell carcinoma (BCC), researchers believe the technology could also be adapted to detect other types of skin cancer seen in Singapore and the region[SB1] .
“NHG has always been exploring ways to transform and impact care for our patients. We are very excited that our National Skin Centre is the first in the region to use reflectance confocal microscopy for diagnosis of skin cancer in place of biopsy. With this, we aim to individualise surgery for our patients, reducing mortality and morbidity for them,” said Prof Steven Thng, Deputy Director and Senior Consultant, National Skin Centre, NHG, and co-author of the study.

New Australian technology is set to transform the way that gastrointestinal cancers are detected and treated with precise, minimally invasive surgery.
Backed by the Federal Government’s Economic Accelerator (AEA) Ignite Grant, researchers from the University of South Australia (UniSA) are using quantum technology to develop a first-of-its-kind laparoscopic probe that will allow surgeons to accurately map the spread of tumours.
The technology has the potential to improve cancer survival rates and patient quality of life worldwide.

FOR IMMEDIATE RELEASE
Physicians have long observed a mystifying phenomenon: After a bout of infection or an autoimmune disease flare-up, some people experience prolonged mood swings, emotional dysregulation, and changes in behavior. But the precise connection between inflammation, mood, and behavior has remained elusive.
Now, two new studies from Harvard Medical School and Massachusetts Institute of Technology, published April 7 in Cell, detail the steps of an intricate brain-immune crosstalk that accounts for this long-known but poorly understood observation.
The work, conducted ...
Researchers have successfully demonstrated the UK’s first long-distance ultra-secure transfer of data over a quantum communications network, including the UK’s first long-distance quantum-secured video call.
The team, from the Universities of Bristol and Cambridge, created the network, which uses standard fibreoptic infrastructure, but relies on a variety of quantum phenomena to enable ultra-secure data transfer.
The network uses two types of quantum key distribution (QKD) schemes: ‘unhackable’ encryption keys hidden inside particles of light; and distributed entanglement: a phenomenon that causes quantum particles to be intrinsically ...
As many as one in 3,000 people could be carrying a faulty gene that significantly increases their risk of a punctured lung, according to new estimates from Cambridge researchers. Previous estimates had put this risk closer to one in 200,000 people.
The gene in question, FLCN, is linked to a condition known as Birt-Hogg-Dubé syndrome, symptoms of which include benign skin tumours, lung cysts, and an increased risk of kidney cancer.
In a study published today in the journal Thorax, a team from the University of Cambridge examined data from UK Biobank, the 100,000 Genomes Project, and East London Genes & Health – three large genomic datasets encompassing more than ...
Thinking creatively, solving complex problems, and working in teams… all add up to Design Thinking (DT). A study conducted by the Escuela Superior Politécnica del Litoral (ESPOL) and Ghent University provides a step-by-step guide for teaching this methodology as a university course.
The main objective of this study is to share the implementation of DT in the first year of all undergraduate programs at ESPOL, considering that previous research has shown that this course fosters essential DT skills in a world of constant change, allowing students to build their own knowledge through experiential learning.
In practice, this study ...

The Food and Drug Administration (FDA) collects user fees from drug and medical device companies to fund its work ensuring the safety of these products. Creating a similar program that collects fees from food companies could generate much-needed resources to strengthen the FDA’s oversight of foods, according to a new legal and policy analysis published in the journal Health Affairs.
“The FDA is persistently understaffed and underfunded, hampering its ability to ensure the safety of our country’s food supply,” said Jennifer Pomeranz, associate professor of public health policy and management at NYU ...
While Food is Medicine programs are successfully helping patients manage their health, many initiatives are small-scale pilots, providing treatment to several hundred or several thousand patients. Results of these studies have demonstrated that these nutrition-based food prescription programs improve a range of health outcomes for patients with diet-sensitive conditions, while also potentially saving in medical costs, suggesting wider implementation and investment would lead to long-term savings and a healthier population.
