Which method is NOT an indication for a chest CT scan in patients with myasthenia gravis?

The answer indicates that routine monitoring through chest CT is not typically indicated for patients with myasthenia gravis. Chest CT scans are generally recommended in specific contexts for this condition, particularly to evaluate for potential associated conditions such as thymoma, which can be found in patients with myasthenia gravis.

After a primary diagnosis is made or after initial diagnosis confirmation, a chest CT is useful to check for abnormalities, particularly in the thymus gland, as interventions might be considered based on those findings. Furthermore, a CT scan might be warranted following a severe exacerbation of symptoms to investigate any acute changes or complications. However, routine monitoring of patients who are stable and without new symptoms does not usually require repeated imaging unless there is a clinical reason to redo imaging.

This makes it clear that while CT scans serve a critical role in specific scenarios, they are not necessary for ongoing monitoring in the absence of new clinical signs or symptoms.
