The Future of Carotid Disease Diagnosis: 3D Reconstruction from 2D Ultrasound

Imagine transforming the diagnosis of life-threatening conditions like carotid atherosclerosis from a lengthy process into a matter of minutes with a single non-invasive scan. That’s the revolutionary capability Sonaro Inc., a Montreal-based medtech startup, offers with its cutting-edge technology. By combining 2D ultrasound imaging with artificial intelligence to create 3D reconstructions of the carotid arteries and provide fully automated analyses, Sonaro is setting a new standard in medical diagnostics.

What is Carotid Atherosclerosis?

Carotid atherosclerosis occurs when plaque builds up in the carotid arteries, which supply blood to the brain. This plaque, composed of fatty deposits, cholesterol, calcium, and other substances, can narrow and harden the arteries, leading to reduced blood flow and increased stroke risk. This condition is a major cause of strokes, which can have devastating consequences, including death, paralysis, speech difficulties, as well as severe cognitive impairments.

The Importance of Accurate Diagnosis

Accurate diagnosis of carotid atherosclerosis is crucial for tailoring effective treatment plans, which can range from lifestyle changes and medications to surgeries. Early detection prevents disease progression, reduces stroke risk, and improves patient outcomes. Accurate diagnosis also helps avoid unnecessary invasive procedures, reducing both complications and costs.

Traditional Imaging Techniques

Traditionally, carotid atherosclerosis has been diagnosed using imaging techniques like CTA (Computed Tomography Angiography), MRA (Magnetic Resonance Angiography), and duplex ultrasonography. Each of these methods has its pros and cons:

• CTA offers detailed images and 3D reconstructions but involves ionizing radiation and contrast agents, which can pose risks for the patient.
• MRA provides excellent soft tissue detail, making it useful for evaluating the extent of carotid atherosclerosis and the composition of the plaque, without radiation, but is expensive and time-consuming.
• Ultrasonography is non-invasive, cost-effective, and widely available, but its effectiveness can be limited by operator skill and the 2D nature of images, which may miss the full extent of irregularly shaped plaques.

Currently, 2D ultrasound serves as the primary imaging tool to diagnosis carotid atherosclerosis due to its clear advantages over CTA and MRA. Yet, its limitations, have led to high misclassification rates (~30%) and a reliance on confirmatory exams (>43%), straining healthcare professionals due to a shortage of vascular specialists.

The Power of 3D Reconstruction

Sonaro’s technology (called Vaso3D^TM) addresses these challenges by using a portable electromagnetic sensor with standard 2D ultrasound devices to capture 2D images and positional data. Advanced algorithms then reconstruct these images into precise 3D visualizations of the carotid arteries and any plaque deposits, offering several key advantages:

• Improved Visualization: 3D models provide a comprehensive view of the artery and plaque, enhancing risk assessment.
• Accurate Measurements: AI algorithms automate 3D model analysis, identifying high-risk plaques and critical stroke risk determinants. The software provides annotated images and quantitative measurements, such as degree of artery stenosis and plaque dimensions, essential for treatment decisions.
• Enhanced Patient Education: 3D models help patients understand their condition, improving engagement in healthcare decisions
• Surgical Planning: Surgeons can simulate procedures for better-informed decisions and improved outcomes.

Additional benefits of Sonaro’s technology include a user-friendly single-sweep procedure, reducing carotid ultrasound examination time by 90%, decreasing reliance on operator expertise, and delivering results within seconds, vastly improving diagnostic timelines and efficiency.

Looking to the Future

The potential of 3D reconstruction from 2D ultrasound imaging is vast. Future developments include:

• Real-Time Imaging: Instant 3D reconstructions during the ultrasound exam could significantly impact clinical decision-making.
• Electronic Health Record Integration: Allows the seamless tracking of disease progression and enhancing communication among healthcare providers.
• Portable and Affordable Devices: Makes advanced vascular assessments accessible in underserved areas and home settings.
• Virtual and Augmented Reality: Revolutionizes medical professionals’ interaction with 3D models for planning and education.
• Patient-Specific Treatment Planning: Tailors interventions to individual needs, optimizing outcomes.

Conclusion

3D reconstruction from 2D ultrasound imaging provides a cost-effective, accessible, and highly accurate alternative to traditional methods like CTA and MRA. Sonaro’s innovative approach not only enhances diagnostic accuracy but also reduces examination time, offering detailed visualizations and fully automated analyses in minutes. This technology is poised to revolutionize the diagnosis and management of carotid atherosclerosis, significantly improving patient care and outcomes.
