Purpose: To assess the usefulness of mandibular
cross-sectional multiplanar reconstruction (CS-MPR)
using 3D sequences in the preoperative evaluation of
mandibular bone marrow invasion of oral carcinomas.
Methods: The subjects consisted of 91 patients with
primary oral SCCs. Mandibular invasion on standard 2D
sequences MR images or 3D sequences images with
mandibular CS-MPR was evaluated. Results: The area under
the ROC curve of CS-MPR was significantly larger (P =
.0024) and improve the specificity for bone marrow
invasion (P= .0077). Conclusion: The mandibular CS-MPR
has the potential to improve the diagnostic performance
for the evaluation of mandibular invasion by SCCs.
