The role of magnetic resonance imaging in assessing the extent of tongue squamous cell carcinoma: A prospective cohort study.

Purpose: To assess the false-positive and false-negative MRI results in evaluating the extent of tongue squamous cell carcinoma.

Methods: A prospective cohort series of 165 patients was enrolled to assess the false-positive and false-negative MRI results in evaluating the extent of tongue squamous cell carcinoma by comparing intraoperative tumor profile images and postoperative pathological sections. The differences between two-dimensional tumor margins were analyzed using Mimics 15.
