You will have a chest x-ray. You will have a performance status evaluation. You will have ECG and MUGA scans or echocardiogram. Samples (1 1/2 teaspoons each) of cerebrospinal fluid from your spine and brain will be collected to look for the presence of cancer cells. The spinal sample will be collected through a spinal tap. The other sample will be taken from your brain through an Ommaya Reservoir tap. Radioactive dye will also be injected into the CSF to make sure the CSF flows freely throughout the spinal canal.
