Due to its potential to revolutionize healthcare systems, the concept of using artificial intelligence (AI) in medical practice has attracted significant attention. However, the unpredictability of AI systems and the never-ending list of ethical and legal concerns made it so only a few AI algorithms have been implemented so far.
One particularly useful use of artificial intelligence is in the realm of content creation, where generative AI excels. And there is content to be created in the medical field. Medical imaging AI has numerous uses in medicine and related fields from better diagnostic imaging analysis to individualized care. That said, there are several other ways in which healthcare stakeholders might benefit from generative AI.
The value of AI in the healthcare industry was US$15.4 billion in 2022, and Grand View Research predicts it to grow at a CAGR of 37.5% from 2023 to 2030. As a result, generative AI and other forms of artificial intelligence will become commonplace in the medical field.
The recent surge in the development of AI technology and the benefits it may bring to the healthcare business have been the main focus of our interest at Mind Studios, where we have been producing specialized healthcare solutions for years. In this article, we'll go over how medical imaging AI can help fix some of the healthcare system's biggest problems.
What is the role of AI in medical imaging and how is it used?
AI and medical imaging assists healthcare workers in identifying trouble regions or details that the human eye may overlook. AI-powered medical imaging, for example, may evaluate data points in a medical report to differentiate a disease (from a healthy portion) and signals (from noise). AI-powered medical imaging is often used to:
- Recognize complicated patterns in image data
- Provide a quantitative assessment of radiographic characteristics
- Identify picture modalities at various stages of therapy (for example, tumor delineation)
- Discover illness features that are not visible to the naked eye
Modern challenges of medical imaging and AI for healthcare data visualization
The primary issues that the healthcare industry faces may be summed up in two words: high costs and poor patient experiences. However, there are several technical obstacles that occur when implementing and employing AI for medical imaging.
Medical imaging
Medical images in the majority of imaging modalities generally suffer from one or more of the following problems during acquisition:
- Low resolution (both spatial and spectral)
- High noise levels
- Lack of contrast
- Geometric deformations
- Imaging artifacts
The introduction of fresh methods in the medical field, such as newer scanners that give new imaging modalities, poses difficulties to medical data visualization research — human professionals spend a lot of time on processing all that data. Besides, in a medical environment, different data kinds are accessible, such as medical imaging scanners, sensors, and patient information. AI can process this huge load of old and new data faster than a human ever could.
Healthcare data visualization
Because of noise, confounding effects, and a lack of standardization in metadata capture, these data types may be unclear, noisy, varied, and difficult to interpret. The core issues of medical data visualization, however, are usually the following:
- Data preparation, which is crucial for high-quality visualization, includes such time-consuming tasks as picture enhancement, segmentation, and data transformation.
- Lack of collaboration between image processing researchers and the development of a taxonomy of medical activities. When done right, it can make medical graphics studies easier to understand and more useful in everyday life.
- Extracting features from medical data is challenging and often requires expert decision-making.
- Data assimilation, combining observed data with computer models, can improve accuracy but faces difficulties in data availability, curation, and ethical issues.
- Access to freely available data is important for innovative visualization approaches, but legal restrictions and patient permission often limit its availability. Likewise, ethical concerns and the lack of regulation standards contribute to challenges in data privacy and usage.
- Standardization is a problem in medical visualization due to the lack of established standards and harmonization for modern imaging methods.
The creation of cutting-edge methods in the healthcare sector is a major motivator for researchers working in the field of medical visualization despite the need for medical licensing. For instance, the introduction of innovative scanners results in novel imaging modalities, each of which has its own set of visual problems. We keep an eye on healthcare technology breakthroughs, such as AI solutions, at Mind Studios and can incorporate them into an existing model or design one for you. Because healthcare is one of our expertise, we know how to create a product that stands out.
How AI helps solve these issues?
The medical industry makes use of a wide range of data types, from patient records to medical imaging scanner and sensor data. One scanner may collect several different types of information, such as multivalued data, as well as single scalar, tensor, and vector fields. Unstructured, partial, or inconsistent medical data might make analysis challenging. This might be due to a number of things, such as inconsistent metadata capture or data noise. X-ray exposure reduction and patient movement are two more possible explanations.
Artificial intelligence can improve several aspects of diagnostic and interventional radiology, including image processing, diagnosis, intervention prescription, clinical predictive modeling, and education.
Better diagnosis efficiency with generative AI in medical imaging
Human error in healthcare settings may be more common due to high patient volumes and a lack of relevant medical history. Artificial intelligence technologies can detect and diagnose illnesses quicker than human doctors while offering better interpretability of medical images.
Reducing healthcare costs
When generative AI in healthcare visualization is used to streamline the diagnostic process, it helps keep healthcare costs down. Imagine a scenario in which AI can search through millions of diagnostic photos for signs of sickness. Manual work is rendered unnecessary. The requirement for inpatient stays can be minimized, as can the time spent waiting for treatment.
Simplifies information sharing
The promise of AI in precision medicine relies on the speed and accuracy with which its algorithms can process large datasets. For instance, in the United States, diabetes now affects 11.3% of the population. Urgent treatment and management are required, and AI can aid medical personnel in making sense of data from a continuous glucose monitoring device to better comprehend the disease.
Use cases of generative AI in areas of healthcare
By improving the analysis of healthcare data and spotting patterns and trends, generative AI is predicted to completely change the healthcare industry. Better machine learning algorithms will increase the scope of applications for generative AI in healthcare, leading to more precise diagnoses and better treatment strategies.
Personalized patient care will be made possible by the combination of generative AI with other technologies, such as medical imaging and wearable health equipment. A more unified and individualized strategy for analyzing and implementing healthcare data is anticipated as a collaboration between providers, academics, and AI technology improves. So, let's take an in-depth look at how generative AI imaging is already assisting doctors and other medical professionals.
Generating high-quality medical images
GANs (generative adversarial networks) are capable of producing high-resolution medical pictures in high detail. Generative AI may be used to produce high-resolution medical pictures, assisting in image quality and detail enhancement. This is very beneficial in fields like radiology and pathology. This is where crisp and precise imaging is critical for correct diagnosis.
A work published in Nature Communications, for example, revealed the use of GANs to create high-resolution brain MRI pictures, which helped increase brain tumor segmentation accuracy.
Aiding in the diagnosis of radiography and pathology
Radiologists and pathologists can benefit from generative AI models when interpreting medical pictures. Indeed, by utilizing deep learning techniques, these models can flag possible anomalies or aid in the identification of certain traits. Furthermore, this contributes to more accurate and efficient diagnostics.
Deep learning, for example, is used in an AI-based image evaluation system created by Google and Northwestern University Feinberg School of Medicine to detect cancerous lung nodules on CT images. While human radiologists often check many 2D lung scans, this approach examines lungs in a single large 3D image, increasing the accuracy of the screening output.
Furthermore, the system has been taught to compare both main and past CT scans, which aids in the prediction of lung cancer malignancy chances. It examines both the area of interest and those with a high risk of lung cancer. When both main and previous CT scans are accessible, the method performs similarly to experienced radiologists, and it exceeds them when a prior scan is not available.
Convolutional neural networks (CNNs) and other generative AI models, on the other hand, can help radiologists and pathologists diagnose illnesses. According to research published in Lancet Oncology, an AI imaging model surpassed human radiologists in identifying breast cancer in mammograms.
Using imaging data to predict disease progression
Longitudinal medical imaging data may be analyzed using generative AI algorithms to forecast illness development. For example, research published in Pubmed employed GANs to accurately forecast Alzheimer's disease development using brain MRI data. So, in the future, these models can give insights into illness trajectories by identifying small changes in pictures over time, as well as assist healthcare providers in making educated decisions about treatment plans and treatments.
Drug discovery
Drug discovery typically takes between three and six years and costs between $600 million to $1.8 billion. In contrast to more conventional approaches, generative AI can assist researchers come up with innovative therapeutic ideas that meet their specific requirements and limits.
It can produce new candidates with comparable features but different structures by training on data relating to the chemical properties of known medications, which might lead to safer and more effective treatments. By evaluating massive amounts of data on drug-target interactions, it can also foretell the efficacy and safety of novel drug candidates.
By evaluating patterns in clinical data, generative AI finds subgroups of patients who are more likely to respond to medicine, hence facilitating personalized drug therapy and better patient outcomes.
Personalized care planning
Personalized treatment planning seeks to personalize healthcare approaches to the unique features of each patient. For this purpose, generative AI systems can be used to enable accurate and optimal treatment options. Furthermore, it is possible to develop treatment regimens for individual patients based on medical history and genetics.
Patient data may be analyzed using generative AI models. In reality, it takes into account medical history, genetic information, and other pertinent data to generate tailored treatment programs. This also includes individual differences and optimizes treatment options, resulting in more effective and focused healthcare treatments.
Concerns about using generative AI for visualization in healthcare
With all the benefits that AI imaging brings to the table, there are still risks associated with AI-assisted imaging and using AI in healthcare visualization, regardless of the speed with which such technologies are reaching medical specialists. They exist, therefore we must weigh the risks against the potential rewards and use this potent instrument properly. Likewise, while generative AI shows great potential, there are several obstacles and ethical concerns that must be resolved before it can be used in healthcare.
Algorithmic bias
The possibility of algorithmic bias is one of the major dangers in the field of Generative AI. Because AI algorithms are educated on historical data, such data might unwittingly reinforce existing prejudices and inequalities. In healthcare, this can lead to discrimination and skewed decision-making that negatively impacts patients.
Strategy for Mitigation: To deal with this issue, it is essential to use stringent data preparation techniques to detect and eliminate bias from training data. To guarantee consistency and openness, AI models should be routinely tested and audited. Involving a wide range of stakeholders and domain experts in the testing and development phases also aids in spotting and correcting for any inherent biases.
Ethical use of AI-generated content
Generative AI systems can produce information that is both realistic and compelling, including diagnostic advice, medical photographs, and reports. However, questions about the veracity and accuracy of such AI-generated information might give rise to moral dilemmas.
Strategy for Mitigation: Establishing Clear Guidelines and Standards for the use of AI-generated content in healthcare is needed to reduce the risk of unethical use. Healthcare workers need to be taught how to assess the quality of AI-generated results and verify them before acting on them. To make sure that generative AI is used to supplement and improve upon clinical knowledge rather than replace it, human supervision and responsibility must be maintained at all times.
Other possible roadblocks include the need for ethical concerns and appropriate datasets with exact labeling and adequate sample numbers to learn from. Furthermore, the intended users of the finished ML system should be reflected in the training data. Finally, it is difficult to employ machines in medical imaging since they do not give a statistical rationale when defining the task's purpose.
