Convolutional Neural Networks and Their Role in Imaging

CNNs, a type of deep learning algorithm, are at the core of AI's success in medical imaging. Why are CNNs so effective? They mimic the human brain's visual processing abilities, allowing the algorithm to:

  • Identify edges, textures, and shapes in images (e.g., identifying tumors or fractures).
  • Learn and improve over time using large datasets of medical scans.
  • Distinguish between subtle differences in normal and pathological tissues beyond human capabilities.

While CNNs and other AI models provide impressive imaging insights, their true potential is unlocked when paired with patient context. That's where EHR systems come in. Integrating AI-powered imaging data with an EHR system provides clinicians with a comprehensive view of the patient's health. For example:

  • A physician examining an X-ray flagged for bone density loss can instantly see prior bone density scores and medications affecting bone health within the EHR.
  • Lab results appended to an AI-generated chest CT report may confirm suspicions of an infectious disease, streamlining the path toward targeted therapy.

Zebra Medical has developed AI algorithms that analyze a diverse range of medical imaging modalities, including CT scans, MRIs, and X-rays. These algorithms detect fractures, cardiovascular abnormalities, and lung nodules. Once the AI review is complete, the results are automatically transferred into the patient's EHR. This allows clinicians to view AI-generated reports alongside the patient's overall medical profile, ensuring that diagnostic insights are informed by clinical context.

 

AI-Related Security Concerns of EHRs 

Although AI has redefined what EHR systems can achieve, it has also become a lucrative target for cybercriminals. A deeper look into these AI-specific threats reveals the scope of the challenges healthcare organizations must mitigate. 

  • Adversarial Machine Learning Attacks involve manipulating data to deceive AI systems, undermining their ability to make accurate predictions or diagnoses. For instance, by altering specific inputs, attackers might trick AI models into misdiagnosing a patient or recommending inappropriate treatments. 

Impact: Imagine a healthcare AI model used to predict critical conditions, such as sepsis. With minor input changes, an attacker could prevent the system from generating alerts, delaying medical intervention, and potentially harming patient outcomes. 

  • Data Poisoning Attacks happen when malicious actors inject corrupted data into the training sets of AI models. This compromises the learning process, leading to unreliable predictions and inaccurate outcomes. When deployed in critical systems like EHR, this can lead to severe consequences, such as inappropriate treatment recommendations. 

Impact: A poisoned dataset could deceive an AI system into predicting false results, like overstating mortality rates, causing unnecessary panic or misallocation of hospital resources. 

  • Membership Inference Attacks happen when attackers determine whether certain data points, such as sensitive patient information, were included in a model's training set. This could expose protected health information (PHI) and violate data privacy regulations like HIPAA. 

Impact: Consider a malicious actor inferring the training data of a cancer prediction model. They could exploit this information to identify individuals with a specific medical condition, violating patient confidentiality. 

  • Model Vulnerabilities From External Sources. Organizations often adopt pre-trained AI models from external sources due to time and budget constraints; however, this introduces significant risks. Third-party models can include "backdoors," allowing attackers to trigger malicious outputs in specific scenarios. 

Impact: An attacker could embed a backdoor into a pre-trained clinical decision-support tool. While the model functions normally in most cases, a deliberate trigger could produce inaccurate results, such as recommending unnecessary surgeries or delaying critical diagnoses. 

Note: When discussing software development for healthcare companies, security is the number one priority. However, to make EHR systems secure, you need to distinguish the type of data being processed. The main concerns revolve around access to medical records and their sharing with third-party entities. Strict regulations, such as HIPAA in the U.S. and GDPR in the E.U., enforce robust controls to ensure patient data is used and shared responsibly. For general analytics or non-sensitive tasks, there is typically more flexibility and fewer restrictions. However, when utilizing commercial AI models from third-party providers, potential risks are reduced, allowing for more creative and innovative applications across healthcare functions.
