New MRI technique allows 3-D imaging of non-living material

The Yale scientists have developed a new method for MRI imaging, which they call “quadratic

echo MRI of solids,” that works by targeting phosphorus atoms instead of hydrogen atoms.
A more complicated sequence of radio waves pulses are fired for them to interact with phosphorus, a fairly abundant element in many biological samples, allowing for high-spatial-resolution imaging. MRI of solids should also be possible with elements other than phosphorus, they say. Read More
