Use Cases: for Stroke Management in the Medical Field

General Description:

The integration of a stroke prediction model and brain pathology with a Large Language Model (LLM) that analyzes clinical histories and medical files in NIfTI (.nii) format allows for a precise and contextual evaluation of each case. This combination facilitates early detection, risk stratification, comprehensive patient management, and personalized follow-up. The models work synergistically to extract relevant information from brain images, correlate it with clinical histories, and provide specific recommendations.

Key Benefits of the Integrated System

1. Early Prediction and Risk Stratification:
   • Pre-trained models analyze brain images in NIfTI format to identify patterns associated with stroke or cerebrovascular lesions.
   • LLMs extract relevant risk factors and medical history from clinical records.
2. Clinical Information Segmentation:
   • Organizes clinical records by diagnoses, previous treatments, current medications, and study results.
   • Correlates these data with findings from medical images for a more comprehensive approach.
3. Advanced Semantic Searches:
   • Enables specific queries like:
     • “Patients at high risk of recurrent stroke.”
     • “Cases with lacunar infarcts detected in NIfTI and history of hypertension.”
4. Detailed Report Generation:
   • Combines brain image data and clinical history into an understandable report highlighting risks, recommendations, and treatment options.
5. Personalized Follow-up Management:
   • Facilitates continuous patient monitoring with personalized plans based on previous findings and risk predictions.

Specific Use Cases

1. Stroke Risk Stratification in Chronic Patients
   • Scenario: A hospital receives patients with a history of hypertension and diabetes, key risk factors for stroke.
   • Process:
     1. The model analyzes clinical records to identify relevant histories such as uncontrolled hypertension, elevated cholesterol levels, or atrial fibrillation.
     2. NIfTI files are processed to identify microinfarcts, ischemic areas, and brain atrophies.
     3. The system combines both analyses to generate a report including:
        • Probability of a stroke in the next 12 months.
        • Preventive recommendations (medication, diet, lifestyle changes).
   • Output: A ranking of patients by risk level, prioritizing interventions in the most urgent cases.
2. Comprehensive Acute Stroke Diagnosis
   • Scenario: A patient arrives in the emergency room with stroke symptoms. The medical team needs to correlate brain images with clinical history to confirm the diagnosis.
   • Process:
     1. The system analyzes NIfTI images to detect arterial obstructions, hemorrhages, or ischemic areas.
     2. The LLM evaluates medical history such as hypertension, smoking history, and anticoagulant use.
     3. It generates a report with:
        • Type of stroke (ischemic or hemorrhagic).
        • Predisposing factors.
        • Acute treatment recommendations, such as thrombolysis or surgical interventions.
   • Output: A detailed report that supports fast, evidence-based decision-making.
3. Post-Stroke Monitoring and Follow-up
   • Scenario: A recovering patient requires continuous monitoring to avoid recurrence and assess treatment effectiveness.
   • Process:
     1. The model analyzes regular NIfTI studies to assess structural changes and new ischemic events.
     2. The LLM reviews updates in the clinical history to detect changes in risk factors or treatment adherence.
     3. It generates a report with:
        • Patient progress (improvement, deterioration).
        • New identified risks.
        • Suggested adjustments to the treatment plan.
   • Output: A continuous summary of the patient’s evolution, available for treating physicians.
4. Comparative Analysis of Treatments
   • Scenario: A hospital wants to evaluate the effectiveness of different treatments for stroke in its patient population.
   • Process:
     1. LLMs classify clinical histories into topics like stroke type, treatments applied (thrombolysis, surgery), and outcomes.
     2. Models process NIfTI images to assess structural changes before and after treatment.
     3. They generate a comparative report including:
        • Recovery rate by treatment.
        • Relationship between outcomes and patient characteristics (age, comorbidities).
   • Output: A data-driven analysis that helps adjust medical protocols.
5. Clinical Audits and Regulatory Compliance
   • Scenario: A medical center needs to evaluate whether stroke cases comply with international guidelines, such as those from the American Heart Association.
   • Process:
     1. The LLM reviews clinical records to verify diagnoses, response times, and therapeutic decisions.
     2. NIfTI models assess whether imaging studies support clinical decisions made.
     3. They generate an audit report including:
        • Cases that meet guidelines.
        • Cases with deviations and clinical justifications.
   • Output: A detailed analysis for internal and external audits.

Key Benefits of the Integrated System

1. Early Detection:
   • Predicts risks before critical events occur, allowing for preventive interventions.
2. Rapid and Accurate Diagnoses:
   • Combines image analysis with clinical history to provide an integrated real-time evaluation.
3. Personalized Follow-up:
   • Facilitates continuous, tailored monitoring according to the patient’s specific needs.
4. Optimization of Medical Protocols:
   • Provides comparative analysis that improves the quality of care and clinical outcomes.
5. Compliance and Transparency:
   • Helps hospitals ensure their practices comply with international regulations.

Conclusion

The combination of stroke prediction models and brain pathology with LLMs that analyze clinical histories and NIfTI files represents a significant advance in healthcare. This system allows for more precise, faster, and contextual case evaluations, improving clinical outcomes, reducing risks, and optimizing patient management. It is ideal for hospitals, research centers, and health systems looking to transform neurological care with AI-based tools.
