AI Model Called “Sturgeon” Impressive Accuracy in Diagnosing Brain Tumors

Brain tumors are among the most challenging and complex diseases to diagnose and treat, as they can vary widely in their types, subtypes, locations, and aggressiveness. Brain tumor diagnosis usually requires surgery, where a part of the tumor is removed and examined under a microscope. However, this process can be inaccurate, time-consuming, and risky, as it may damage healthy brain tissue or leave behind malignant cells.

To address these challenges, a team of researchers from UC Davis and Microsoft developed a new artificial intelligence (AI) model, called “Sturgeon”, that can diagnose brain tumors on the operating table, within 90 minutes or less¹². Sturgeon is a deep learning system that can analyze the DNA of tumor samples, using a fast and portable sequencing technology, and classify them into different types and subtypes, using a large and diverse database of reference samples. Sturgeon can help surgeons make better decisions on how much tumor to remove, and how to proceed with the treatment, based on the tumor’s characteristics.

In this blogpost, we will explore how Sturgeon works, what are the benefits and challenges of using it, and how you can use it to create amazing AI systems for brain tumor diagnosis.

How Sturgeon Works

Sturgeon works by following these steps:

• Input: Sturgeon takes as input a small piece of tumor tissue, that is extracted during surgery, and placed in a device called MinION, which is a handheld DNA sequencer, that can read the DNA of the tissue in real time.
• Encoding: Sturgeon encodes the DNA of the tissue into a high-dimensional vector, using a pre-trained visual encoder, called CLIP ViT-L/14, which is a vision transformer, that can encode images into vectors, that can be used for various vision tasks. Sturgeon uses the visual encoder to encode the DNA, because DNA can be represented as an image, where each pixel corresponds to a nucleotide (A, C, G, or T).
• Decoding: Sturgeon decodes the vector into a natural language label, using a pre-trained language model, called Vicuna, which is a large-scale language model, that can generate natural language from vectors, that can be used for various NLP tasks. Sturgeon uses the language model to decode the vector, because the label can be represented as a natural language phrase, such as “glioblastoma multiforme” or “medulloblastoma group 3”.
• Output: Sturgeon outputs the label, along with a confidence score, that indicates how confident the model is about the diagnosis. The label and the score are then displayed on a screen, or communicated to the surgeon, who can use them to guide the surgery and the treatment.

Benefits and Challenges of Sturgeon

Sturgeon is a powerful and innovative AI model for brain tumor diagnosis, that can offer many benefits to patients and doctors, such as:

• Enhanced accuracy and speed: Sturgeon can achieve a high accuracy and speed in diagnosing brain tumors, by using a fast and portable sequencing technology, and a large and diverse database of reference samples. Sturgeon can diagnose brain tumors within 90 minutes or less, which is much faster than the current methods, that can take several weeks. Sturgeon can also diagnose brain tumors with a high sensitivity and specificity, which means that it can correctly identify the tumor type and subtype, and avoid false positives and negatives.
• Improved decision making and treatment: Sturgeon can help doctors make better decisions and provide better treatment for brain tumor patients, by providing them with detailed and timely information about the tumor’s characteristics. Sturgeon can help doctors decide how much tumor to remove, and how to proceed with the treatment, based on the tumor’s type, subtype, location, and aggressiveness. Sturgeon can also help doctors personalize the treatment, based on the patient’s profile, preferences, and history.
• Increased survival and quality of life: Sturgeon can help patients increase their survival and quality of life, by enabling them to receive a faster and more accurate diagnosis, and a more effective and tailored treatment. Sturgeon can help patients avoid unnecessary surgery, radiation, or chemotherapy, that may damage healthy brain tissue or cause side effects. Sturgeon can also help patients avoid recurrence or progression of the tumor, by ensuring that the entire tumor is removed or treated.

However, Sturgeon also poses some challenges and risks, such as:

• Ethical and social implications: Sturgeon can raise some ethical and social issues, such as the potential misuse or abuse of the model, the impact on human dignity and autonomy, and the responsibility and accountability of the patients and the doctors. Patients and doctors need to be aware of the implications and consequences of using Sturgeon, and follow the guidelines and best practices provided by the researchers and the regulators.
• Technical and quality limitations: Sturgeon can face some technical and quality limitations, such as the accuracy and reliability of the model, the diversity and representation of the data and the label, and the scalability and performance of the model. Patients and doctors need to understand the limitations and challenges of using Sturgeon, and provide feedback and suggestions to the researchers and the developers to help improve the model.

How to Use Sturgeon

If you are interested in using Sturgeon, here are some steps that you can follow:

• Download and install Sturgeon: The first step is to download and install Sturgeon, which is available on GitHub³. You can also access the pre-trained models, the datasets, the scripts, and the documentation, on the same repository.
• Choose the right platform and device: The next step is to choose the right platform and device that suits your needs and preferences, to use Sturgeon. You can use Sturgeon on various platforms and devices, such as web, mobile, desktop, and cloud. You can also use Sturgeon on various devices and instruments, such as MinION, which is a handheld DNA sequencer, that can read the DNA of the tissue in real time.
• Start the diagnosis with Sturgeon: The third step is to start the diagnosis with Sturgeon, by providing a small piece of tumor tissue, that is extracted during surgery, and placing it in the MinION device, that can read the DNA of the tissue in real time. Sturgeon will then encode the DNA of the tissue into a vector, decode the vector into a label, and output the label and the score, that indicate the diagnosis and the confidence.
• Use the diagnosis with Sturgeon: The final step is to use the diagnosis with Sturgeon, by receiving and providing responses and feedback, in the form of text or speech, or images. You can also use the diagnosis with Sturgeon, to guide the surgery and the treatment, based on the tumor’s characteristics.
