Final answer:
If suprascapular compressive symptoms persist despite a negative MRI, additional tests like nerve conduction studies, EMG, or ultrasound should be considered to further investigate and confirm the diagnosis.
Step-by-step explanation:
When a patient presents with suprascapular compressive symptoms such as shoulder pain and weakness, and MRI results are negative, further diagnostic approaches need to be considered. Magnetic resonance imaging is a powerful diagnostic tool, but it may not always detect all pathological conditions, especially when related to nerve compression or subtle soft tissue abnormalities. In such cases, clinicians may consider additional tests such as nerve conduction studies or electromyography (EMG) to assess the function of the suprascapular nerve. Another advanced imaging modality like ultrasound may be useful to visualize any structural changes in the soft tissues not captured by MRI. These additional diagnostic tools can help confirm the diagnosis and guide treatment plans.
