Current imaging techniques are often suboptimal for the
detection of mandibular invasion by squamous cell
carcinoma. X-ray Computed Tomography is more suited to
differentiate bone pathology but can miss fine changes
to the cortex from partial voluming and artifacts.
Standard MRI has excellent soft tissue contrast but
cannot resolve signal from bone due to ultra-short T2
insensitivity. The aim of this study was to determine
the feasibility of a ultra-short T2 sensitive MRI -
based technique known as sweep imaging with Fourier
transform (SWIFT) to visualize the structural changes of
intramandibular anatomy during invasion in-vivo.
