Summary

Real-time True Fast Imaging with Steady Precession (TrueFISP) MRI effectively visualizes swallowing in dysphagia patients. High temporal resolution is key for accurate oropharyngeal functional exploration.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gastroenterology

Background:

  • Dysphagia, a swallowing disorder, requires accurate diagnostic tools.
  • Real-time Magnetic Resonance Imaging (MRI) offers potential for dynamic functional assessment.

Purpose of the Study:

  • To evaluate different real-time True Fast Imaging with Steady Precession (TrueFISP) MRI sequences.
  • To assess their efficacy in depicting the swallowing process and oropharyngeal pathologies in dysphagia patients.

Main Methods:

  • Used a 1.5 T MRI scanner with high-performance gradients.
  • Evaluated four real-time TrueFISP sequences with varying parameters (TR, TE, matrix size, acquisition time).
  • Assessed water, yoghurt, and semolina pudding as oral contrast agents in volunteers and patients.

Main Results:

  • The fastest TrueFISP sequence (TR 2.2 ms, TE 1.1 ms, matrix 63x128) provided the best visualization of swallowing.
  • Increased acquisition time led to anatomical blurring.
  • Semolina pudding yielded the best image quality among tested contrast agents.
  • Real-time TrueFISP MRI successfully visualized swallowing with oral contrast agents.

Conclusions:

  • Real-time TrueFISP MRI is a viable technique for visualizing the swallowing process in dysphagia.
  • High temporal resolution is more critical than spatial resolution for functional swallowing assessment.
  • This technique aids in delineating oropharyngeal pathologies during swallowing.
