The phenomenal advancements in machine learning and artificial intelligence have revolutionized the healthcare industry.
The global market for AI in healthcare in 2016 was about one billion, and this number is estimated to shoot up to more than $28 billion by 2025. The market size of global AI in Medical Imaging, in particular, was estimated to be around $980 million in 2022. Moreover, this figure is projected to rise at a CAGR of 26.77% to $3215 million by 2027.
What is Medical Image Annotation?
The healthcare industry is leveraging the potential of ML to deliver enhanced patient care, better diagnostics, accurate treatment predictions, and drug development. However, there are a few areas of medical sciences where AI can aid medical professionals in medical imaging. Yet, to develop accurate AI-based medical imaging models, you need massive amounts of medical imaging labeled and annotated accurately.
Medical image annotation is the technique of accurately labeling medical imaging such as MRI, CT scans, Ultrasounds, Mammograms, X-Ray, and more to train the machine learning model. In addition to imaging, medical image data such as records and reports are also annotated to help train clinical NER and Deep Learning models.
This medical image annotation helps train deep learning algorithms and ML models to analyze medical images and improve diagnosis accurately.
Role of Medical Image Annotation in Medical Diagnostics
The potential of AI in medical image diagnosis is immense, and the healthcare industry is taking the help of AI and ML to provide a faster and more reliable diagnosis to patients. Some of the use cases of healthcare image annotation in AI medical diagnostics are:
Cancer cell detection is perhaps the biggest role of AI in medical imaging analysis. When models are trained on massive sets of medical imaging data, it helps the model accurately identify, detect and predict the growth of cancer cells in organs. As a result, the potential for human errors and false positives can be eliminated to a large extent.
Teeth and gum-related medical issues such as cavities, abnormalities in teeth structure, decay, and diseases can be accurately diagnosed with AI-enabled models.
Complications related to the liver can be detected, characterized, and monitored effectively by assessing medical images to detect and identify anomalies.
Medical image annotation helps detect brain disorders, clots, tumors, and other neurological issues.
Computer vision and medical imaging are also extensively used to detect dermatological conditions quickly and effectively.
AI is also being increasingly used in cardiology to detect heart anomalies, heart conditions, the need for intervention, and interpreting echo cardiograms.
Types of Documents Annotated through Medical Image Annotation
Medical data annotation is a crucial part of machine learning model development. Without proper and medically accurate annotation of records with text, metadata, and additional notes, it becomes challenging to develop a valuable ML model.
It would help if you had extremely talented and experienced annotators for medical image data. Some of the various documents that are annotated:
- CT Scan
License High-quality Healthcare/Medical Data for AI & ML Models
Medical image annotation VS Regular data annotation
If you are building an ML model for medical imaging, you should remember that it is different from regular image data annotation in so many ways. First, let’s take the example of radiology imaging.
But before we do that, we are laying out the premise – all photos and videos that you’ve ever taken come from a small fraction of the spectrum called the visible light. However, radiology imaging is made using X-Rays which come under the invisible light portion of the electromagnetic spectrum.
Here is a detailed comparison of medical imaging annotation and regular data annotation.
|Medical Imaging Annotation||Regular Data Annotation|
|All medical imaging data should be de-identified and protected by Data Processing Agreements (DPA)||Regular images are readily available.|
|Medical Images are in DICOM Format||Regular images can be in JPEG, PNG, BMP, and more|
|Medical image resolutions are high with a 16-Bit Colour profile||Regular images can have an 8-Bit Colour profile.|
|Medical images also contain units of measurement for medical purposes||Measurements pertain to the camera|
|HIPAA compliance is strictly required||Not regulated by compliance|
|Multiple images of the same object from different angles and views are provided||Separate images of different objects|
|It should be guided by radiology controls||Regular camera settings are accepted|
|Multiple slice annotations||Single slice annotations|
When building AI-based healthcare models, you have to train and test them using huge quantities of high-quality medical images annotated accurately to deliver an accurate prediction. However, when choosing a platform for your medical image annotation and data processing needs, you should always look for offerings that satisfy these technical compliance requirements.
HIPAA is a federal law that governs the safety of electronically transmitted health information and mandates appropriate measures to be taken by providers to protect and safeguard patient information from being disclosed without the patient’s consent.
- Is there a system for healthcare information storage and management?
- Are the system backups created, maintained, and updated regularly?
- Is there a system to prevent unauthorized users from accessing sensitive medical data?
- Is the data encrypted during rest and transfer?
- Are there any measures preventing users from exporting and storing medical images on their devices, causing a security breach?
