Carbon-13 Magnetic Resonance Spectroscopy in Glycogen Storage Diseases
Using Carbon-13 Magnetic Resonance Spectroscopy to Assess Whether High Glycogen Levels in Skeletal Muscle of Patients With Glycogen Storage Diseases is a Prelude for Muscle Damage.
Source: ClinicalTrials.gov · Last updated 11 Aug 2025
Brief summary (registry, in English)
The project will use carbon-13 magnetic resonance spectroscopy to assess whether high glycogen levels in skeletal muscle of patients with Glycogen Storage Diseases is a prelude for muscle damage. Patients with Glycogen Storage Diseases will be examined using carbon-13 MR-spectroscopy to quantify the glycogen levels in lumbar, thigh and calf-muscles. The pattern of glycogen concentration will be compared to the pattern of muscle atrophy found in the literature.
