There are numerous applications of Generative AI in medicine & healthcare – one of the most vital and impactful domains of human well-being. Let’s explore a few of the most game-changing ones of them.
Drug discovery is among the most promising ways Generative AI is transforming healthcare. The process involves finding new molecules or compounds that possess the required properties or effects, such as targeting specific diseases or reducing side effects. The challenge with drug discovery is that it is a complicated, expensive, and time-consuming process and comprises numerous steps, such as screening, synthesis, testing, and optimization.
Generative AI, however, can accelerate and improve the process of drug discovery by helping design novel molecules or compounds that are diverse as well as effective. By utilizing existing data such as chemical structures, biological activities, or molecular properties, it can generate new candidates that match specific criteria or objectives. It can further evaluate the performance or potential of the candidates using various metrics or models and optimize them.
Here are a few examples of successful or promising Generative AI models for drug discovery.
Developed by DeepMind, it is a deep-learning model that can predict the 3D structure of proteins from their amino acid sequences. Protein structure is crucial to understanding the function of proteins and their interaction with other drugs. Essentially, AlphaFold can aid in the discovery of new drugs that bind to particular proteins or targets.
Insilico Medicine developed this Generative AI reinforcement learning model to design new molecules, possessing desired molecular activities. It utilizes existing data from public databases or proprietary sources to generate novel molecules that have high scores for certain properties or effects. It is also possible to synthesize and test the generated molecules in the laboratory using GENTRL.
Medical imaging is another prominent application of Generative AI in medicine. It is the process of capturing images of the internal structures or organs of the human body, which include X-rays, CT scans, MRI scans, or ultrasound images. It plays a vital role in diagnosing diseases, monitoring treatment progress, and planning surgical procedures.
Generative AI can elevate medical imaging by helping in the generation, manipulation, and improvement of medical scan images. This can help augment the existing data, and improve the quality and clarity of the images. It can also help in better interpretation and understanding of the images. For instance, Generative AI can help with various tasks concerning medical imaging, including image synthesis, segmentation, inpainting, super-resolution, and translation.
Let’s look at some prominent examples of Generative AI models for medical imaging.
There are several tech giants that have developed GAN-based models to improve medical imaging. For instance, NVIDIA developed a model that can help generate high-quality synthetic brain MRI images from text labels. Google created a model to inpaint missing regions of retinal images with realistic details. Facebook has also created a GAN-based model that can translate chest X-rays to CT scans with realistic textures and structures.
Generative AI can also segment medical scans into different regions or structures, such as organs, tissues, tumors, or lesions. For instance, Microsoft developed a VAE-based model that can segment brain tumors from MRI images with high accuracy and efficiency.
Through personalized medicine, Generative AI can help tailor medical treatment to the individual characteristics of each patient, such as their genetic makeup, medical history, or lifestyle. This way, it can help improve the effectiveness and safety of medical interventions, along with, reducing the cost and time of trial and error.
Generative AI can learn from various sources of data, such as genomic sequences, clinical records, or wearable devices, and generate predictions or recommendations that are specific to each patient. Thus, it can help achieve personalized medicine by allowing the identification of optimal drug dosage, combination, or timing for each patient based on their genetic profile and response to treatment.
Here are a few noteworthy names that are looking to leverage Generative AI to enable personalized medicine.
It is a biotechnology company striving to discover new therapies for genetic diseases, using Generative AI services. It employs deep learning to model the molecular interactions and effects of genetic variations on human cells. It can thus create and prioritize novel drug candidates that can correct or modify faulty genes or proteins.
With an aim to optimize drug dosing and therapy for individual patients, InsightRX, a software platform, uses Bayesian modeling to learn from patient data, such as demographics, biomarkers, or pharmacokinetics. This way, they generate personalized dosing recommendations that can achieve the desired clinical outcomes while minimizing adverse effects.
Nowadays, more and more healthcare facilities and medical institutions are leveraging natural language processing (NLP) by means of Generative AI tools that can understand and generate natural language texts or speech. This way, they utilize NLP to improve communication and information exchange between doctors and patients, and/or among medical professionals.
NLP enables the creation of natural language texts or speech from data, such as images, audio, or structured data, thus helping in the generation of new data for communication or documentation purposes. For instance, utilizing NLP, Generative AI can generate medical reports from images of medical scans, or synthesize speech from text for voice assistants.
Below mentioned are a few remarkable examples of Generative AI models or NLP in healthcare.
Containing diverse types of data, including demographics, vital signs, laboratory tests, medications, notes, and discharge summaries, MIMIC-III is a large-scale dataset of de-identified electronic health records from intensive care unit patients. It can be used to train generative AI models to generate realistic and coherent medical texts for various purposes, such as summarization, completion, or paraphrasing.
It is a conversational agent that uses Generative AI to make phone calls on behalf of users. With the ability to understand natural language speech and generate natural-sounding speech with human-like intonation and pauses, it can be used to perform tasks such as booking appointments, making reservations, or confirming information.
Generative AI can play an essential role in analyzing and interpreting biological data using computational methods – also known as bioinformatics. Using bioinformatics, it becomes possible to uncover the molecular mechanisms and functions of life processes, such as gene expression, protein interaction, or metabolic pathways.
Generative AI can take bioinformatics to the next level by creating models that can learn from biological data, such as DNA sequences, protein structures, or gene networks, and generate new data that can provide insights or hypotheses for biological problems. For instance, Applying Generative AI to bioinformatics can enable the discovery of new biological patterns or motifs from DNA sequences or the generation of synthetic biological sequences that have specific properties or functions.
