Neuroradiology involves the diagnosis and treatment of brain, spinal cord, head and neck, and vascular lesions using x-rays, magnetic fields, radio waves, and ultrasound.

Imaging modalities used to diagnose pituitary tumors include:

CT scan
• Usually done with intravenous contrast injection for assessing

 the pituitary gland.
• May be done without contrast injection for surgical planning.
• The patient lies on the bed in the gantry of the scanner.
• The x-ray tube is contained in the circular part of the scanner

MRI scanMRI scan
• Can be done with or without contrast, or both with and without intravenous contrast
• The contrast agent is different than that for CT
• A head coil is placed around the head to obtain the images
• The machine makes banging, tapping, drum beat sounds
