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.
