A patient is seen in the clinic for a neuromuscular disease. What neurological test helps to diagnose this type of health problem?
1. single-photon emission computed tomography (SPECT)
2. positron emission tomography (PET)
3. magnetic resonance imaging (MRI)
4. electromyogram (EMG)
Correct Answer: 4
An electromyogram (EMG) measures the electrical activity of skeletal muscles at rest and during contraction and is useful in diagnosing neuromuscular disease. A SPECT is a nuclear scan that provides information about blood flow. A PET scan provides information about cellular function and is useful in diagnosing heart disease and cancers. An MRI uses magnetic fields to produce images of body structures.
