A new cancer imaging technique developed by researchers at Heriot-Watt University in edinburgh is showing “extremely encouraging” results in its first clinical trials. The innovative approach, which leverages existing ultrasound technology, has demonstrated a 94% sensitivity rate in detecting prostate tumors, considerably outperforming current diagnostic methods. What’s more, the test can be completed in under 20 minutes, making it a faster and more efficient option.
Addressing the Challenges of Prostate Cancer Diagnosis
Prostate cancer is a prevalent disease, affecting one in eight men in their lifetime. In the UK alone, there are approximately 52,000 diagnoses each year. Current diagnostic methods rely heavily on a prostate-specific antigen (PSA) test, which has proven to be unreliable. This frequently enough leads to unnecessary and expensive MRI scans, with long waiting lists adding to the burden on patients and healthcare systems.
The existing methods have notable limitations. Up to 28% of clinically significant tumors are missed using current methods, and a staggering one in two individuals with positive MRI findings receive a negative biopsy result.
A Novel Approach to Prostate Imaging
Less Gray Imaging Ltd, a spin-out company from Heriot-Watt University, has developed a revolutionary technology that offers clinicians a 20-fold increase in resolution compared to traditional MRI scans. The company highlights that MRI images frequently enough appear “grey and tough to read,” while their new technique provides exceptional clarity.
The process begins by injecting a commonly used contrast agent into a vein. This agent contains millions of tiny, harmless microbubbles that travel through the patient’s bloodstream to the prostate. The team then employs a technique called super-resolution ultrasound imaging (SRUI) to track these microbubbles as they flow inside the prostate.
As cancerous tissue exhibits altered blood flow, the image highlights previously undetectable tumors, enabling earlier diagnosis and treatment.
Transforming Prostate Cancer Care
Dr. George Papageorgiou, chief executive of less Grey Imaging, emphasized the potential of this technology: “Our initial clinical findings in prostate imaging align well with histopathology, highlighting its potential to reliably detect clinically significant prostate cancer. Currently, prostate cancer diagnosis varies widely across the country, with many patients being diagnosed too late for curative treatment. By integrating ultrasound more prominently into the diagnostic pathway, we can ensure equal opportunities for early diagnosis across all regions of the UK.”
He further explained that the software utilized in their approach leverages existing ultrasound equipment and enhances image quality down to microscopic detail. This diminishes the reliance on radiologist assessment, streamlining workflows, reducing NHS costs, and improving patient efficiency.
The innovation hasn’t gone unnoticed. Innovate UK, the UK’s innovation agency, has awarded Less Grey Imaging a £370,000 (€446,000) grant in recognition of the technology’s potential.
Early Detection for Better Outcomes
Professor Vassilis Sboros,from Heriot-Watt University and co-founder of Less Grey Imaging,explained the impact of this technology on healthcare: “back in 2019,we proved the concept worked in our lab,but now we have shown it works during our initial patient trials. It’s just like looking inside the body with a microscope, allowing clinicians to see 20 times more detail than before. Even concealed tumors are possible to identify.
With one man dying from prostate cancer every 45 minutes in the UK, professor Sboros highlighted the urgency of improving early detection: “We hope earlier detection will radically improve treatment outcomes, saving lives while reducing the number of people sent for unnecessary and often risky tests.”
support From Medical Professionals and Patients
Professor Alan McNeill, a consultant urological surgeon at the Western General Hospital, Edinburgh, and founder trustee of charity Prostate Scotland, is excited about the trial results: “The initial trial results are extremely encouraging, providing really useful data for the diagnosis and treatment of prostate cancer. This is the most common cancer in men but, if it is caught early while the cancer remains within the prostate, it can be cured in the majority of cases.”
Gary Tait, who was treated for prostate cancer five years ago and is now chairman of Edinburgh & Lothian Prostate Cancer Support group, expressed his support for the new technology: “From the outlook of men who are unaware of a developing tumor in their prostate, this improved method of diagnosis could lead to earlier treatment which improves the likelihood of a good outcome. We fully support the development of this new technology which raises the possibility of enabling more men to be both diagnosed and treated earlier than they can be at present.”
How does SRUI enhance the quality and clarity of prostate images compared to customary MRI scans?
High-Quality Professional Interview with Dr. George Papageorgiou, Chief Executive of Less Gray Imaging Ltd.
Archyde News Editor: Good afternoon,Dr. Papageorgiou. Thank you for joining us today to discuss the groundbreaking advancements in prostate cancer imaging developed by Less Gray Imaging Ltd.
Dr. Papageorgiou: Thank you for having me. It’s a pleasure to share our exciting progress in prostate cancer diagnostics.
Archyde News Editor: Let’s start with the big picture. Prostate cancer is a meaningful health issue, affecting one in eight men in their lifetime. Current diagnostic methods,like the PSA test and MRI scans,have notable limitations. can you outline the challenges these methods pose?
Dr. Papageorgiou: Certainly. The PSA test, which measures prostate-specific antigen levels, is widely used but has a high rate of false positives and negatives. This often leads to unneeded MRI scans, which are expensive, time-consuming, and have long waiting lists. Moreover, even with MRI, there’s a considerable issue: up to 28% of clinically significant tumors are missed, and about half of patients with positive MRI findings end up with negative biopsy results. This creates a lot of uncertainty and stress for patients.
Archyde News Editor: That’s a significant gap in current diagnostics. Yoru team at Less Gray Imaging Ltd has developed a novel approach called super-resolution ultrasound imaging (SRUI). Could you explain how this technology works and what makes it revolutionary?
Dr. Papageorgiou: Absolutely. Our technology leverages existing ultrasound systems but enhances them dramatically. We inject a contrast agent containing microbubbles into the patient’s bloodstream. These microbubbles travel to the prostate, and we use SRUI to track them. Becuase cancerous tissue has altered blood flow, the microbubbles highlight tumor areas that traditional imaging methods often miss. This gives us a 20-fold increase in resolution compared to MRI scans.
Archyde News editor: That’s impressive. In your initial clinical trials, SRUI demonstrated a 94% sensitivity rate in detecting prostate tumors. How significant is this result compared to current methods?
Dr. Papageorgiou: Extremely significant.Traditional methods like MRI are not as reliable, missing a substantial number of tumors. Our 94% sensitivity rate means we’re catching nearly all clinically significant tumors, which allows for earlier diagnosis and treatment.This can drastically improve patient outcomes.
Archyde News Editor: Another notable aspect of SRUI is its efficiency. The test can be completed in under 20 minutes. How does this speed impact patients and healthcare systems?
Dr. Papageorgiou: Speed is crucial. A 20-minute test means patients can get results quickly, reducing anxiety and uncertainty. For healthcare systems, it alleviates the burden of long waiting lists for MRI scans and cuts down on unnecessary procedures. This efficiency can drive significant cost savings and improve overall care.
Archyde news Editor: Your technology also offers extraordinary clarity in imaging. You’ve described traditional MRI images as “gray and tough to read.” How does SRUI improve image quality?
Dr.Papageorgiou: SRUI provides much clearer, high-resolution images. Traditional MRI scans often have unclear areas, making it difficult for clinicians to make confident diagnoses. SRUI removes this ambiguity, giving clinicians a reliable and detailed view of the prostate. This clarity is game-changing for accurate diagnosis.
Archyde News Editor: What’s the next step for SRUI? Are there plans to expand its use beyond prostate cancer imaging?
Dr. Papageorgiou: We’re focused on advancing prostate cancer diagnostics for now, but the potential applications are vast. The principles of SRUI could be adapted for other cancer types and even non-cancerous conditions where detailed imaging is crucial.We’re excited to explore these possibilities.
Archyde News editor: what message do you have for patients and healthcare professionals regarding this breakthrough?
Dr. Papageorgiou: I want to emphasize hope and progress. For patients, this technology offers a more accurate, faster, and less stressful diagnostic process. For healthcare professionals, it provides a powerful tool to enhance care. We’re committed to transforming prostate cancer diagnosis and improving outcomes for everyone affected by this disease.
Archyde News Editor: Thank you, Dr. Papageorgiou,for this insightful conversation.Your work at Less Gray Imaging Ltd is truly groundbreaking, and we look forward to seeing its impact on prostate cancer care.
Dr. Papageorgiou: Thank you. We’re excited to continue advancing this technology and making a positive difference in healthcare.
