Understanding Your Diagnosis

  • Brain Tumor: Diagnosis
  • X-rays of the Skull

    X-rays use invisible electromagnetic energy beams to make images of internal tissues, bones, and organs on film. Standard X-rays are done for many reasons, including diagnosing tumors or bone injuries.

  • Computed Tomography (CT or CAT) Scan of the Brain

    Computed tomography (CT or CAT scan) is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs.

  • Computed Tomography (CT or CAT) Scan of the Spine

    Computed tomography is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays.

  • Magnetic Resonance Imaging (MRI) of the Spine and Brain

    MRI may be used to examine the brain and/or spinal cord for injuries or the presence of structural abnormalities or certain other conditions, including tumors or aneurysms.

  • Positron Emission Tomography (PET)

    A positron emission tomography (PET) scan is a type of nuclear medicine imaging test. It is used to examine various body tissues to identify certain conditions by looking at blood flow, metabolism, and oxygen use. PET scans may also be used to see how well the treatment of certain diseases is working.

  • Electroencephalogram (EEG)

    An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.

  • Craniotomy

    A craniotomy is the surgical removal of part of the bone from the skull to expose the brain for surgery. The surgeon uses specialized tools to remove the section of bone (the bone flap). After the brain surgery, the surgeon replaces the bone flap.

  • Brain Tumors: Newly Diagnosed

    It’s OK to feel overwhelmed and afraid. But you shouldn’t let those feelings stop you from finding out as much as you can about your cancer and about the options you have.

  • Brain Tumor: Grades

    Before your doctor can recommend a treatment plan, he or she needs to know the grade of the cancer. The grade tells your doctor how malignant the tumor is and how it might respond to treatment.

  • Myelogram

    A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography (CT) to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.
