Evaluation of swallow function after tongue cancer treatment using real-time magnetic resonance imaging: a pilot study.

ABSTRACT:

Importance

Magnetic resonance imaging (MRI) has the advantage of imaging swallow function at any anatomical level without changing the position of patient, which can provide detailed information than modified barium swallow, by far the gold standard of swallow evaluation.

Objective

To investigate the use of real-time MRI in the evaluation of swallow function of patients with tongue cancer.

Design, setting, and participants

Real-time MRI experiments were performed on a Signa Excite HD 1.5-T scanner (GE Healthcare), with gradients capable of 40-mT/m (milli-Tesla per meter) amplitudes and 150-mT/m/ms (mT/m per millisecond) slew rates. The sequence used was spiral fast gradient echo sequence. Four men with base of tongue or oral tongue squamous cell carcinoma and 3 age-ma
