AB  - OBJECTIVE: The aim of this study was to compare magnetic resonance imaging (MRI) 
      features of reconstruction with locoregional flaps (LRFs) with free flaps (FFs) 
      after surgical treatment for tongue cancer. STUDY DESIGN: In total, 115 cases of 
      postoperative tongue carcinoma (67 cases of LRF surgery and 48 cases of FF 
      surgery) were retrospectively reviewed. All patients had undergone nonenhanced 
      and contrast-enhanced MRI at 0-4, 5-12, and 13-48 months after surgery. Signal 
      intensity, margins, maximal size, contrast enhancement, change in the hyoglossus 
      and mylohyoid muscles, recurrence, lymph node metastasis, and complications were 
      evaluated. RESULTS: Significant differences were found between LRF and FF for 
      signal intensity (P < .001) in all 3 periods, with LRF mostly isointense with 
      muscle on T1-weighted images (T1WIs) and FF producing mixed hyperintensity with 
      muscular striations in all cases in T1WIs and T2-weighted images (T2 WIs). Margin 
      definition was similar between groups in the early period, but sharp margins were 
      more common in FF after 4 months (P </= .018). LRF was significantly smaller than 
      FF in all periods (P </= .017). Both mylohyoid and hyoglossus enlargements were 
      common in the early period in both groups, but all cases became atrophic later. 
      CONCLUSIONS: MRI can differentiate LRFs from FFs in a variety of parameters after 
      flap reconstructive surgery for tongue cancer.
