Longitudinal Functional Magnetic Resonance Imaging to Assess Lung Disease in Cystic Fibrosis

Abstract Rationale Matrix pencil decomposition magnetic resonance imaging (MP-MRI) enables quantitative assessment of lung ventilation and perfusion and was shown to correlate with contrast-enhanced (CE) perfusion MRI. Objectives To determine the longitudinal course of MP-MRI par...

VQ-Wave: A Physics-Driven Spatiotemporal Deep Learning Approach for Noncontrast-Enhanced Lung Ventilation and Perfusion MRI.

Purpose To develop a robust deep learning framework for noncontrast-enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity.Methods We introduce VQ-Wave (Ventilation/Q-perfusion Waveform-based Assessment...
