Analyst Take: Researchers from Google have reported that their latest model Med-PaLM 2, a multimodal biomedical AI, has achieved a remarkable 86.5% accuracy on USMLE-style questions, representing a substantial 19% improvement over their previous state-of-the-art results with Med-PaLM. Med-PaLM 2 was developed focusing on challenges in the medical field, such as early disease detection, medical image analysis, and personalized treatment recommendations. The integration of AI with biomedicine provides the opportunity for healthcare experts to improve patient outcomes, allowing healthcare experts the ability to quickly and accurately analyze extensive data, such as medical images, electronic health records (EHRs), and scientific literature, unlocking greater efficiency and precision.

What is unique about Med-PaLM 2 is its ability to process and analyze multimodal data including medical images, such as X-rays, MRIs, and CT scans, along with clinical data, patient histories, genetic information, and medical literature. This ability enables Med-PaLM 2 to offer more comprehensive and accurate insights into complex medical conditions than a healthcare expert is able to do. To develop Med-PaLM 2, the team of researchers assembled MultiMedBench, which is an extensive multimodal medical dataset, encompassing 14 tasks across text, medical imaging, and genomics. For example, MultiMedBench has more than 1 million examples that are tailored for tasks ranging from question answering, report generation, classification, and other clinically significant objectives. MultiMedBench played a pivotal role in training and assessing the biomedical capabilities of Med-PaLM 2.

Med-PaLM 2 Benefits

  • Multimodal Data Analysis: Med-PaLM 2 can process and analyze multimodal data, allowing it to uncover patterns that are difficult or time-consuming for healthcare experts, improving diagnostic accuracy and providing more personalized patient treatment recommendations.
  • Early Disease Detection: Med-PaLM 2’s algorithms enable healthcare experts to identify early signs of diseases, providing patients with timely interventions and improved prognosis.
  • Precision Medicine: Med-PaLM 2 enables healthcare experts to develop personalized treatment plans tailored to each individual patient, which ensures more effective and targeted therapies.
  • Speed and Efficiency: Med-PaLM 2 can analyze large datasets in a fraction of the time it would take healthcare experts, allowing them to make more informed decisions quickly.

Through language-based instructions and prompts, Med-PaLM 2 applies its knowledge on new medical tasks and concepts and demonstrate multimodal reasoning without specific training. For example, Med-PaLM 2 displayed accurate identification and description of tuberculosis in chest X-rays, even though it had never been exposed to images of the disease before. In addition, clinicians preferred Med-PaLM 2 reports over radiologists’ reports in up to 40.5% of cases in a direct comparison of 246 retrospective chest X-rays.
