Tuesday, April 29, 2025, 15:00-16:00
The Health AI and Data Science (HAD) Program presents
End-to-End AI Pipeline for V/Q Imaging: From Data Extraction to PE Burden Quantification
Speaker: Amir Jabbarpour
Amir Jabbarpour is a 3rd-year PhD candidate in Medical Physics, developing AI-driven solutions for ventilation/perfusion (V/Q) scintigraphy in the pulmonary embolism context. His research focuses on integrating deep learning into Nuclear Medicine, Radiotherapy, and broader Medical Imaging challenges. His passion for this field was sparked by the idea of applying radiation physics to human anatomy—strategically harnessing radiation to either capture detailed diagnostic images or precisely target and eliminate cancer.

Seminar Summary and Learning Objectives

This presentation outlines the development of a comprehensive AI-enhanced workflow for ventilation/perfusion (V/Q) imaging, focused on batched data extraction, improving image quality, pseudo-planar V/Q image generation, diagnostic accuracy, and clinical interpretability in pulmonary embolism (PE) assessment. The talk covers the following key components:

1. Data Acquisition and Integration

  • Automated querying of relevant clinical cases from the Electronic Medical Record (EMR)
  • Extraction and curation of imaging studies from the Picture Archiving and Communication System (PACS)
  • Streamlined downand preprocessing of V/Q scan data for AI training and inference

2. Image Quality Enhancement and Count Correction

  • Development of an AI model to enhance the quality of V/Q images
  • Pseudo-planar V/Q image generation

3. Defect Segmentation Using Deep Learning

  • Design and training of a segmentation model to localize perfusion and ventilation defects
  • Handling multiple projections and aligning outputs across views

4. Anatomical Mapping and PE Burden Quantification

  • Mapping segmented defects to a standard lung atlas for anatomical localization
  • Automated quantification of PE burden across lung lobes for objective reporting

5. Clinical Relevance and Future Directions

  • Integration within clinical workflows
  • Toward real-time decision support in nuclear medicine and radiology
  • Direct application in other diseases (COPD, CTEPH, functional avoidance radiotherapy, and lobectomy) and other departments (Thrombosis)
