Horizons in Healthcare: FDA-Approved Multimodal and Adjunctive AI Transforms Ultrasound Patient Care

Generative artificial intelligence (AI) and machine learning (ML) are already proving to be a transformative force for ultrasound. The U.S. Food and Drug Administration (FDA) is now taking an ever-increasing role in shaping the regulatory environment to accommodate these technological advancements and AI/ML in healthcare.

The agency’s latest guidance and the burgeoning number of AI/ML-enabled medical devices mark a significant shift in diagnostic and treatment paradigms. It’s proof that the future is here — and there’s an imperative to focus on using advanced technologies to bolster the standard of patient care.

New regulatory landscapes

In April 2023, the FDA issued groundbreaking draft guidance for the regulation of AI/ML-enabled device software functions. This move represents a significant shift from the agency’s traditional approach of regulating hardware-based medical devices, adapting to the more dynamic, iterative nature of AI/ML technologies. The new framework recognizes that multimodal and adjunctive AI/ML can “optimize performance over time and continuously learn from real-world experiences.”

The FDA’s introduction of the Predetermined Change Control Plan is a pivotal aspect of this new regulatory landscape. Under this plan, manufacturers are required to submit detailed descriptions of planned AI/ML modifications; methodologies for developing, validating, and implementing those modifications; and an impact assessment to evaluate the benefits and risks of changes.

This approach enables continuous improvement of AI/ML algorithms in health care without necessitating repeated submissions for each modification when updates align with the predetermined plan. The FDA’s guidance facilitates the advancement of AI in ultrasound, medical technology, ensures the safety and effectiveness of evolving tools, and potentially accelerates the availability of advanced healthcare solutions.

Enhanced diagnostic capabilities

Formal guidance from the FDA comes on the heels of a wave of AI/ML adoption that’s already underway. As of January 2023, the FDA has cleared over 500 AI algorithms in healthcare, predominantly enhancing medical imaging capabilities.

These algorithms have revolutionized diagnostic procedures across various specialties such as radiology, cardiology, and neurology, offering more accurate and efficient pattern recognition and image analysis. This surge in AI-driven diagnostics has led to improved identification of diseases, enabling earlier and more precise treatments.

Still, we’re only on the cusp of its potential. Adjunctive AI in ultrasound and medical imaging extends beyond diagnosis. It automates time-consuming tasks like quantification and report completion, improves workflow, and offers clinical decision support (CDS). This not only accelerates the diagnostic process but also ensures higher accuracy and consistency in results.

In the realm of ultrasound, AI’s ability to enhance image quality and resolution — as well as guide less experienced users in optimizing images — illustrates its profound potential to improve patient care and diagnostic standards.

Change in healthcare: new practices, processes, and expectations

The adoption of AI for ultrasound in healthcare extends far beyond clinical diagnostics. It will profoundly alter practices, processes, and expectations within the field.

Nonclinical applications of AI/ML in healthcare are rapidly proliferating, particularly in healthcare IT systems, where they play a critical role in managing and interpreting vast amounts of patient data. This includes applications in population health management, health-tracking apps, and identification of gaps in health equity. Multimodal AI is also being used to streamline processes — such as revenue cycle management — and to improve hospital-wide operations: monitoring admittance, bed turnover rates, and early detection of conditions like sepsis.

These changes signify a broader transformation in healthcare, emphasizing a more data-driven approach. AI’s role in enhancing patient wellness and preventive care is becoming increasingly prominent. AI/ML in healthcare enables healthcare providers to offer more personalized and efficient care, optimizing patient outcomes.

As AI in ultrasound and healthcare applications continues to evolve, it’s reshaping the healthcare landscape by fostering a more proactive, predictive, and patient-centric approach to healthcare. This shift necessitates a reevaluation of existing healthcare practices and models.

AI/ML: the future of diagnostic imaging

With the surge in FDA-approved AI applications, the future of healthcare offers more precise, personalized, and data-driven patient care. This ongoing evolution underscores the importance of balancing innovation with patient safety, ensuring that as healthcare strides forward into this new era, it remains anchored in the principles of efficacy and ethical responsibility. This technological progression isn’t just enhancing diagnostic accuracy and efficiency; it’s also an opportunity to reinvent healthcare practices and expectations, with the guidance of companies with ultrasound and healthcare AI experience.
