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.
