Purpose: To investigate the relationship between the
features of extrinsic muscle/ neurovascular bundle
invasion demonstrated by 3T-MR modalities and treatment
outcome in patients with tongue cancer. Methods: 3T-MRI
studies of 168 subjects with tongue cancer were
retrospectively reviewed with particular attention for
extrinsic muscle / neurovascular bundle invasion.
Results: Extrinsic muscle invasion (P = 0.001) and
neurovascular bundle invasion (P = 0.003) were
significant predictors for cervical lymph node
metastases. Conclusion: MRI may contribute to prediction
of cervical lymph node metastases with tongue cancer.
