AI in Diagnostics: How Machine Learning is Revolutionizing Early Disease Detection

AI for patient care is no longer an alien concept. From extensive research to early prognosis, AI in healthcare has been a game changer, especially with Machine Learning (ML) models. They have also expanded the scope of early disease detection and personalized treatment options. With population expansion, AI-powered diagnostic tools are setting new healthcare standards like never before.

• The global AI healthcare market is poised to reach $188 billion by the end of 2030.
• AI in medicine can save up to 10% on spending and dramatically reduce hospital admissions by at least 50%.
• 4 out of 5 (over 80%) pathologists believe that AI in healthcare can boost longevity.

No wonder leading healthcare brands are bent on investing in custom healthcare software development to better their service standards, bend the curve, and stay ahead of the competition.

In this article, you will learn how machine learning as a subset of AI in healthcare is pushing the status quo for medical diagnosis, its accuracy, and success, and why investing in custom software development for healthcare is the need of the hour.

Why Machine Learning For Medical Diagnosis Anyway?

When it comes to patient diagnosis, pathologists traditionally do a wide range of microscopic work. Deep machine learning is the only viable tech that holds the common thread for all small, medium, and large-scale diagnostic applications. This is because ML can work by evaluating a range of physiological data along with genetic and environmental factors.

For clinicians working with multiple medical datasets, things have always been a challenge as they involve critical analysis of imaging reports (X-rays, CT scans, USGs) and varied systems. With machine learning, they can always do better in mitigating inherent risk factors for more than one reason.

• AI in healthcare lowers the number of diagnostic errors, which is a major problem that accounts for thousands of deaths annually.
• With ML models, analyzing patient data at a granular level is easy, thereby detecting similar patterns in critical conditions.
• Flagging critical areas for medical images that humans might miss
• Analyzing multiple tissue samples with precision and detecting abnormalities early on

How is Machine Learning Being Used In Medical Diagnosis?

Whether it's managing workflows or automating daily non-core tasks, AI in healthcare has been ticking the right boxes. Modern healthcare professionals have turned towards using emerging machine learning tools to flag abnormal findings across patient data and thereby prioritize life-threatening scenarios. Cases of stroke, chronic inflammation, and cardiac arrhythmia are some of the potent examples.

But that's not all. Machine learning also extends its offerings to a string of vital functions that include:

• Pathological diagnosis of diseases straight from lab reports
• During oncology to help with biopsies in recognizing cancerous tissues
• Diagnosis of rare and genetic diseases based on observed phenotypes
• Analysis of patient vitals using facial analysis
• Identifying patterns across patient systems for provisional diagnosis and recommending treatment options

But How Accurate is Machine Learning In Healthcare?

While there's no denying the goodness of AI and machine learning in healthcare, there's no denying the skepticism. So, let's address the elephant in the room: Is machine learning-based analysis accurate for improving healthcare standards? Let's understand things in detail.

AI in healthcare has had far-reaching positive effects, ranging from drug development to gene editing. Machine learning tools have been downright insightful, and the credit goes to causal reasoning powered by multiple algorithms. This is in stark comparison to earlier diagnosis models where only correlated symptoms were taken into consideration.

In a leading research study, Dr Richens, along with his colleagues, highlighted machine learning algorithms to determine the possibilities of a patient's symptoms, taking multiple factors into account.

It was also found that artificial intelligence in the medical field can abstract certain alternate realities and reconsider more symptoms if the patient was diagnosed with a different disease earlier.

Such reiterations made way for ML algorithms to score higher in written cases (7 out of 10 doctors). Here are some of the most potent conditions where machine learning in healthcare is driving better outcomes.

Detection of Skin Cancers

Researchers from Stanford University reportedly trained a deep-learning algorithm to diagnose skin cancer during its onset. Using a CNN (Convolutional neural network), the ML algorithm picked up early anomalies across patient data and detected melanoma by referring to multiple large datasets (more than 130,000 skin lesion images and another 2000 different medical conditions). Such early detection not only helped improve the prognosis but also lowered mortality rates.

A Breakthrough in Cellular Pathology

Pathologists generally work with microscopic images to diagnose different medical conditions. And this has been the case for centuries. With machine learning, however, there is a breakthrough, as depicted in a research study conducted by the Beth Israel Deaconess Medical Center and Harvard Medical School comprising hundreds of scan results to accelerate diagnosis.

The scans highlighted both cancerous and non-cancerous cells, which contributed to significant training data. The ML algorithm helped achieve 92% accuracy in diagnosis, which is marginally lower than human diagnosis. However, when human diagnoses and algorithm prediction were combined, the results showed 99.5 % accuracy!

Diabetes Management

Diabetes is a one-of-a-kind chronic disease that we all know and fear. It's called a silent killer for a reason, as many patients don't even feel the symptoms until it reaches an advanced stage. That's why early diagnosis becomes so essential.

With AI in the picture, detecting the early onset of diabetes is made easy by analyzing patient data like dietary habits, glucose levels, and activity patterns. AI models can deeply scrutinize the data and flag individuals who might be at a high risk of developing diabetes. Additionally, it also suggests positive, preventive measures to stop the disease from manifesting itself.

Today, diabetes prevention is much simpler using real-time glucose monitoring tools like CGMs, which measure a person's blood glucose levels throughout the day. This alone offers personalized recommendations for diet, insulin dosage, and exercise. Several healthcare brands that have already invested in custom healthcare software development are now using ML algorithms to take genetic data into account and identify therapeutic targets to expand the scope of personalized treatment.

Advancing Diagnosis For Neurological Disorders

Conditions like Alzheimer's disease, Parkinsons, and multiple sclerosis throw significant challenges for early diagnosis. The symptoms often mimic other lesser harmful conditions, which can leave doctors baffled. By the time the correct diagnosis is made, it's already too late. But AI-assisted healthcare is here to change things.

With Machine learning algorithms, doctors can now analyze browsing through multiple brain scans and genetic data to spot early symptoms that may not be visible to the naked eye. Take Alzheimer's disease, for instance, where AI algorithms can be effectively trained to recognize and record significant changes across brain structure well ahead of time before the symptoms start appearing.

Furthermore, the tools can analyze MRI scans to detect patterns associated with the early stages of neurological conditions. This can significantly slow the progression of a disease. For a condition like Parkinson's, AI is the chief driving force in designing improved diagnostic tools that collect data from wearable devices and detect changes in movement (tremors and stiffness) as early signs.

In the case of multiple sclerosis, machine learning allows fast analysis of imaging data to identify changes across the spinal cord and brain. This helps patients who are at risk of developing severe symptoms or relapsing. For the attending medical professional, such early diagnosis can help tailor customized treatment options.

Enhancing rheumatoid arthritis treatment

Researchers at the Queen Mary University of London reportedly utilized AI-powered tools to analyze multiple blood samples collected from rheumatoid arthritis patients. This helped track the response rate for antirheumatic medications, which didn’t have the same positive impact on every patient.

There have been cases where several rheumatoid arthritis patients experienced severe side effects from the medicines prescribed to them. In time, their condition worsened before a different treatment method could be introduced. This is where AI-powered diagnostic tools came in, helping doctors take on a more focused and personalized approach as one could foretell the effectiveness of drugs and save patients from critical side effects (like heart attacks).

On the other hand, a separate UK-based research team went on to develop a machine-learning model to identify red flags for all coronary occurrences. This led to the development of a new biomarker known as the fat radiomic profile that detected early anomalies around the perivascular space.

As explained in the European Heart Journal, the AI-powered app could identify genes that were closely associated with changes like scarring and inflammation. Also, the dataset comprised multiple test biopsies from over 160 cardiac operations. In many critical cases, it was observed that the narrowing of the coronary artery doesn’t permanently exclude the possibility of a heart attack. Therefore, the AI-led diagnosis identified related characteristics around the blood vessels for timely intervention.

Early Detection of Diseases through Biomarker Analysis

Machine learning is revolutionizing early disease detection through biomarker analysis, especially for conditions like cancer, cardiovascular diseases, and neurodegenerative disorders that are hard to diagnose early. AI algorithms analyze biomarkers - measurable indicators in bodily fluids or tissues that signal normal or abnormal processes. These include proteins, genes, metabolites, and microRNA patterns.

In cancer detection, ML models trained on biomarker datasets can identify subtle patterns indicating cancer presence earlier than traditional methods. For instance, a Nature Medicine study showed ML could detect ovarian cancer two years earlier through blood biomarker analysis.

For cardiovascular disease, AI models combine traditional risk factors with newer biomarkers to better predict heart attacks and strokes. In Alzheimer's detection, ML analyzes biomarkers from blood tests, brain imaging, and behavioral changes for early diagnosis.

ML's strength in biomarker analysis comes from its ability to:

• Identify complex patterns
• Process large datasets
• Learn continuously
• Provide personalized assessments

Improving Patient Care Standards

According to the US Institute of Medicine, diagnostic errors are responsible for almost 10% of patient deaths and treatment-led complications. While the expertise of a medical professional always remains debatable, most diagnostic errors were either due to poor communication or non-integrated IT that failed to respond on time.

AI in healthcare, besides contributing to early diagnosis and drug development (especially in early trials), also helps clinical staff reduce their work burden. AI-powered systems can not only streamline operations in hospitals and clinics but also boost working capacity without sacrificing precision. Take the radiology department, for instance, where specialists can work with programmable ML algorithms to flag scanner images and prioritize emergency cases.

Will the Medical World Accept AI Results in Diagnostics?

As we've seen, ML is making substantial impacts across various medical fields, including oncology, neurology, and chronic disease management. It's not just about detecting diseases earlier; it's about revolutionizing patient care, reducing diagnostic errors, and ultimately saving lives.

The future of healthcare is tied to AI and ML. As these tools get better, we can look forward to even more advanced ways to diagnose and treat illnesses. But it's key to keep in mind that while AI makes medical abilities stronger, it doesn't take away the need for human doctors. Instead, it empowers healthcare professionals to make more informed decisions and provide better care.

AI is becoming more popular in medical diagnoses because it has the power to boost accuracy, productivity, and results for patients. While there are still hurdles to overcome when it comes to keeping data private, following rules, and fitting in with current systems more people are starting to use and trust AI tools for diagnosis. Looking ahead, healthcare will mix AI tech with human know-how leading to more exact, personalized, and successful medical treatment.
