Brain Imaging Techniques Quiz

• Conventional x-ray photography is not useful for visualizing the brain.
• Contrast x-ray techniques involve injecting a substance that absorbs x-rays either less or more than the surrounding tissue to heighten contrast during x-ray photography.
• Cerebral angiography is a contrast x-ray technique that uses the infusion of a radio-opaque dye into a cerebral artery to visualize the cerebral circulatory system during x-ray photography.
• Cerebral angiograms are useful for localizing vascular damage and indicating the location of a tumor.
• Computed tomography (CT) is a computer-assisted x-ray procedure that can be used to visualize the brain and other internal structures of the living body.
• During cerebral CT, the patient lies with their head positioned in the center of a large cylinder, and an x-ray tube and detector rotate around the head to take individual x-ray photographs.
• The meager information in each x-ray photograph is combined by a computer to generate a CT scan of one horizontal section of the brain.
• Scans of eight or nine horizontal brain sections are typically obtained from a patient during cerebral CT.
• The combination of scans can provide three-dimensional representations of the brain.
• These techniques revolutionized the study of the living human brain in the early 1970s.
