- Dysphagia is a debilitating symptom in neuromuscular disorders, leading to severe complications like malnutrition and aspiration pneumonia.
- The study evaluated dysphagia in inclusion body myositis (IBM) and oculopharyngeal muscular dystrophy (OPMD) using real-time MRI (RT-MRI) and quantitative muscle ultrasound (QMUS).
- RT-MRI showed prolonged oral transit times in OPMD and prolonged pharyngeal transit times in IBM compared to controls.
- A cricopharyngeal bar, indicative of dysphagia, was found in 80% of IBM patients and 53% of OPMD patients.
- Fatty degeneration of the tongue in OPMD correlated between MRI-T1 values and ultrasound echogenicity.
- Combining RT-MRI, T1-mapping, and QMUS provided excellent discrimination between diseases (AUC = 0.95), outperforming FEES and clinical assessments.
- The study highlights the utility of novel imaging techniques for diagnosing and treating dysphagia in neuromuscular disorders.
