Only recently, a Fourier decomposition (FD) method was
suggested to extract perfusion and ventilation
information (parenchyma density) from a time series of
co-registered 2D images. Generally, FD requires dynamic
sampling with high temporal resolution and nonrigid
image registration, currently limiting this technique to
2D only. Here, we introduce a simple method to visualize
regional parenchyma density (ventilation) directly and
in 3D using high-resolution isotropic ultra-fast
balanced steady state free precession (bSSFP) scans at
1.5T acquired within a single breath-hold.
