+
+Lung ventilation is important because ...
+
+The use of MRI for mapping ventilation has grown significantly recently
+Key events: FDA approval of HPX, dissemination of 2D V/Q methods, multiple advances in respiratory phase-resolved imaging
+
+Already in 2025 two papers have been published on structure/function methods using phase-resolved 3D UTE MRI, and comparing them to HPX ventilation

+
+MRI Ventilation Methods
+
+* HPX - pros: direct measurement, cons: specialized equipment, costs
+* 2D phase-resolved methods (Fourier Decomposition, PREFUL)
+* Oxygen Enhanced
+* Structure/function with phase-resolved 3D UTE
+
+Technical Challenges 
+
+* Importance of image registration
+* Ventilation processing - most of these methods provides relative, not absolute, measures of ventilation, so additional processing is required.  Usually VDP.  I think some of the differences between the two papers is due to differences in this processing
+
+Experimental Challenges
+
+* Physiologic - breath-hold versus tidal breathing versus forced exhalations could lead to different measurements
+
+
+Add in a couple key images.  Also want a small image for the 'logo' of the post that is references by 'image:' at the top
