Reconstructive and aesthetic facial plastic surgery can
strongly benefit from quantitative assessments of the
facial soft-tissue mobility. This clinical challenge can
be risen by a modern and original comprehensive imaging
method, joining advanced MRI and image analysis. In
particular, 3D accelerated upright MRI provides, in
reasonable acquisition times, high-resolution and
high-contrast facial soft-tissue depiction in natural
stance under physiological weight-bearing. Moreover,
soft-tissue layer watershed segmentations and their
constrained elastic registration between lying and
sitting positions give access to full quantitative
information about the complex 3D anatomy of the face
structure, as a function of aging and gravity.
