Deep learning assisted detection of chronic lung allograft dysfunction using pulmonary DCE-MRI

Key Points

The model achieved an average AUROC of 98.5%, showing exceptional accuracy in detecting chronic lung allograft dysfunction.
Using transfer learning from the VGG-16 model, the approach effectively processed spatial and temporal data from 3D DCE-MRI scans.
The method utilized an 8-fold cross-validation strategy to rigorously assess model performance and reliability.
This deep learning framework may enhance the diagnostic precision for chronic lung allograft dysfunction in lung transplant recipients.

Abstract

Motivation: Chronic Lung Allograft Dysfunction (CLAD) is a significant cause of mortality among lung transplant recipients, making early detection crucial for timely intervention. Goal(s): This study aimed to evaluate a deep learning-based method for distinguishing patients with CLAD from non-CLAD using 3D DCE-MRI of the lungs. Approach: We developed a model using transfer learning from pre-trained VGG-16 model weights and evaluated model performance by 8-fold cross-validation. Results: The model achieved an average AUROC of 98.5%, indicating high accuracy in distinguishing between CLAD and non-CLAD cases. Impact: This deep learning approach effectively combines spatial, depth, and temporal information from 3D DCE-MRI, offering a promising tool for enhancing CLAD diagnostic precision.
