Medical Imaging Use Case Development Guidance

Machine learning and deep learning models help in medical imaging by analysing large amounts of clinical and imaging variable to provide personalised risk assessments and tailored management plans. 

Key benefits

CDSS empowers doctors, nurses, patients, caregivers, pharmacists and others to make more informed decisions to deliver effective care.

  • Faster and better diagnosis
  • Detect bone fractures and tumours
  • Detect and characterise strokes, traumatic brain injuries and dementia
  • Monitoring of disease progression
  • Distinguish between benign and malignant tumours

Use Case Examples

NanoxAI using AI medical imaging technology to screen for early signs of chronic disease in large populations. This enables more accurate risk-adjustment so patients are provided with preventative care paths they need, while improving quality of health services at significantly lower associated costs.


Use case development template

Here is the guidance to help you develop business and a high-value use case for Medical Imaging using Artificial Intelligence and Machine Learning.

This Medical Imaging use case framework guidance describes Esdha's current research on the topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited.

Challenges & Opportunities



Operational Impact: Poor data quality can affect the quality of decisions.

System monitoring & maintenance: Healthcare institutions have reported difficulty in monitoring and maintaining the knowledge base, algorithms, rules and data. 

Lack validity: as users can become more reliant on Medical Imaging systems without questioning the accuracy of the recommendation provided. 

Knowledge base: overall knowledge creation with the clear evidence base for incorporating recommendation is a challenge and requires specialist input from various care professionals.

Interdisciplinary team: We need an interdisciplinary team consisting of computer scientists and clinicians to align goals, requirements and clinical trial outcomes.

Accountability: There is a need for frameworks on medical malpractice liability for AI medical imaging.

Cost: due to lack of standardised metrics, it is hard to do cost benefit assessment as cost-effectiveness depends on a range of socio-economic factors including environment, political and technological.

Potential risks & mitigation

Explainability: There is risk associated with misunderstanding recommendations or wrongfully assume causality as explanations are correlation-based, they can be susceptible to error due to random factors. Explainability is useful as long as the outputs are sufficiently accurate, validated and required by the user.
 
Wrong or misleading recommendation: can result in loss of trust or serious consequences. 

Privacy & quality: adherence to data protection and privacy requirements such as the general data protection regulation (GDPR) will be essential. A standardised approach to data collection can help to address this risk.

Bias, overfitting and validity: build a rigorous criterion to evaluate for biases (such as statistical misrepresentation to the general population), overfitting, and validity.
