The test is quick and relatively non-invasive, so doctors often use it to rule out neurologic disorders as the cause of muscle weakness. Muscular dystrophy patients typically have a higher concentration of fat in their muscles.
MRIs help neurologists understand which muscles MD is affecting the most. They also help doctors choose a suitable muscle for a biopsy, if needed. MRI scans over time help physicians track the amount of fat infiltrating muscle tissue, which tends to correlate with changing muscle strength and function.
To perform a muscle biopsy , a doctor collects a small piece of muscle with a needle or by making a small cut in the skin. Doctors use a microscope to check the sample for muscle damage and to look at levels of different muscle proteins, certain concentrations of which can indicate muscular dystrophy. Low levels of dystrophin protein can indicate that a person has certain types of the disease, such as Duchenne muscular dystrophy and Becker muscular dystrophy.
