Recent advances have transformed the use of standard clinical MRI equipment in functional lung imaging.2 We recently presented a clinically appropriate dynamic oxygen-enhanced MRI (dOE-MRI) protocol.3 In this work, we interpret dOE-MRI data with a novel physiological model of gas exchange4 that maps the regional distribution of lung ventilation and perfusion, simulating results from a standard V/Q scan.3D dOE-MRI data were acquired using a 1.5 T Philips scanner as in:3 a 5 min baseline T1 acquisition, followed by a 15 min dynamic acquisition, during which the subject breathed 100\\% O2 for the middle 5 min. Total scan time is under 30 min throughout which the subject breathes normally. The partial pressure of oxygen in the alveolar compartment was derived as proposed in5 and maps of regional alveolar ventilation and perfusion were produced using a novel two-compartmental model of gas exchange based on.4Figure 1 shows an example of whole-chest ventilation and perfusion maps from a healthy subject overlaid on a single volume of the acquired MRI (left column). The same maps are displayed as anterior/posterior and right/left anterior oblique projections (right column), equivalent to those achieved with V/Q scintigraphy.1Abstract P284 Figure 1 ~Estimation of alveolar ventilation and perfusion distribution from 3D dynamic OE-MRI is feasible and can be obtained under clinically acceptable conditions using standard radiological equipment without ionising radiation risks. This approach opens the possibility for regional assessment of lung physiology using a single short scanning session.References 1 Bajc, et al.

Previously, dOEMRI has been limited to single slice imaging. Capturing the whole lung within a single breathing cycle increases the utility of dOEMRI in identifying regional alterations in lung function. In this work, we evaluate a novel quantitative whole lung 3D dOEMRI protocol based on a single-shot 3D MPRAGE sequence available on many scanners2.METHODS: Sequence parameters were optimised to maximise contrast in the lung when switching from air to O2 during free breathing. The protocol was evaluated on a 1.5T Philips Achieva scanner in 4 healthy volunteers (3 which had repeat scans). Baseline T1 maps were acquired while subjects breathed medical air. This was followed by a 15min dynamic scan (temporal resolution 10s), during which gas supply was switched from air to 100\\% O2, and back to air. Dynamic data were converted to ΔPO2 maps and parameterised with an exponential model of O2 wash-in and wash-out1.RESULTS: Figure 1 shows an image volume overlaid with a map of O2 wash-in and ΔPO2 time series of all the subjects scanned. The same exponential model was applied to the group average ΔPO2.CONCLUSIONS: These results are the first to show the feasibility of volumetric whole lung dynamic OEMRI.REFERENCES: 1 Kershaw et al.
