How are astrocytomas diagnosed?
Diagnosing astrocytomas can be difficult due to symptoms being similar to other neurological disorders. Some labs may be drawn, such as a complete blood count, basic metabolic profile, and blood clotting times, but are often normal. Radiological tests are used to diagnose astrocytomas.
What tests are used in diagnosing astrocytomas?
Magnetic resonance imaging (MRI) is the standard study. Computed tomography (CT scans) may be used if a patient cannot have an MRI. Other tests include:
- Angiography
- Positron emission tomography (PET scans)
- Electroencephalography (EEGs)
- Electrocardiograms (ECGs)
- Chest X-rays
- Cerebrospinal fluid studies
A biopsy may be done to determine a definitive diagnosis.
