Transverse (top row) and coronal (bottom row) sodium MRI of the human knee ex vivo without and with IR (rectangular and WURST pulses). The images are averaged over 2 slices for better visualization. The same range scaling is applied to all the images. Human knee images were acquired with 10000 projections. The coronal slice was chosen to pass through the PBS tube in order to show the strong suppression inhomogeneities of the rectangular inversion pulse (horizontal yellow line). Note the uniform and complete fluid suppression with the WURST inversion pulse in the PBS tube and the very non-uniform fluid attenuation obtained with the rectangular pulse.
