Quantitative susceptibility mapping (QSM) and
susceptibility tensor imaging (STI) are two recently
developed imaging methods, which provide quantitative
information of tissue chemical composition, especially
myelin and iron, exquisite anatomic details, and unique
information of white matter microstructures of the
brain. Both QSM and STI require sophisticated steps for
3D phase unwrapping, background phase removal, and
dipole inversion to derive magnetic susceptibility or
susceptibility tensors. Here, we provided our methods
for phase preprocessing, QSM, and STI, and its related
graphical user interfaces as a Matlab-based software
package, named as STI Suite, for free academic use.
