1 Slide 1 Computed Tomography (CT): A simplified Topographical review of the Brain Jon Wheiler, ACNP-BC Slide 2 Tomography vs Topography Tomography: A technique for displaying a representation of a cross section through a human body or other solid object using X-rays or ultrasound: Topography: A detailed description or representation on a map of the natural and artificial features of an area: Slide 3 Learning Objective To reinforce and expand your knowledge base regarding computed tomography and brain anatomy whereby enhancing your function as a Healthcare provider.
2 Slide 4 Disclosure: I am not a Radiologist, Neuroradiologist, Neurologist, Neurointensivist, or Neurosurgeon: I have no financial affiliation with any commercial supporters of this conference: Slide 5 Outline Computed Tomography Design and Function Neuroanatomy Head CT Mapping Slide 6 Computed Tomography Basics
3 Slide 7 Computed Tomography (CT) Physics Physics of CT simplified: CT is comprised of a rotating Xray source and detector The X-rays are absorbed in varying degrees by different tissues A computer assigns numerical numbers based on tissue density Hounsfield Units (HUs) : Sir Godfrey Newbold Hounsfield HU Table: Air Substance HUs Water 0 Air Bone Fat -120 Anatomy Windowing: Water 0 Center HU value Muscle +40 Width - +/- Bone +400 Numerical Values based on density Slide 8 Pneumocephalus Cerebral Spinal Fluid Brain Tissue: Gray & White Matter Bone Blood EVD Slide 9 Computed Tomography Scan The images generated are generally in the axial or transverse plane, modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. Axial Sagittal Coronal
4 Slide 10 Computed Tomography Brain: Uses Uses: Blood (Intracranial hemorrhage, Trauma, Cerebral Edema) Ischemia (Stroke, Trauma, Encephalopathy) Enlarged s (Hydrocephalus, Trauma, ICH) Foreign Objects (Trauma, GSW, Diseases) Brain Mass/Lesion Diseases or malformations of the cerebral vasculature, brain tissue, and/or skull Slide 11 Brain Terminology - a convoluted ridge between anatomical grooves Cerebri:- two folds of Dura mater separating the hemispheres of the brain (falx cerebri) Cerebral Cortex: brain matter differentiated into gray and white matter characteristically connected by different layers and neuronal types Sulcus - a shallow furrow on the surface of the brain separating adjacent convolutions Fissure - any of the deep clefts of the brain ; (Lateral [Sylvian] fissure) Slide 12 Brain Terminology Cistern widened subarachnoid spaces/reservoir for storing CSF: usually found at the base of the brain Sinuses a dilated channels found between layers of Dura mater in the brain for venous blood flow. Meninges: Dura Arachnoid Pia matter. The system of membranes which envelops the central nervous system. The dura being the outermost, thickest layer. Tentorium cerebelli - an arched fold of dura mater forming a partition between the cerebrum and cerebellum:
5 Slide 13 Brain Terminology Choroid Plexus - is the area on the ventricles of the brain where cerebrospinal fluid is produced by modified ependymal cells. Ventricular System - A system of communicating cavities in the brain that are continuous with the central canal of the spinal cord providing a pathway for CSF Ganglia: the "basal ganglia" is a group of nuclei interconnected with the cerebral cortex, thalamus and brainstem Slide 14 Insula (Insular Cortex) considered the 5 th lobe of the cortex which separates the temporal lobe the parietal lobe dorsally. Hemisphere left and right: Dominant vs Nondominant s purely anatomical classification of areas of the brain related to different brain functions. Frontal lobe, Parietal lobe, Temporal lobe, Occipital lobe, Insula, and Cerebellum. Regions Functional and cognitive areas of the brain as related to function: Sensorimotor Area, Hindbrain, Midbrain, Forebrain, & Neural pathways. Brain Terminology Slide 15 Anatomical Terminology Posterior Toward the back situated behind; dorsal. Anterior Before or in front of the abdominal side of the body. Dorsal going from the belly to the spinal column. Ventral going from the spinal column to the belly. Caudal Inferior in position towards the tail. Cephalad Superior in position towards the head/top. Inferior Beneath below the undersurface. Superior Higher than Situated above. Medial Pertaining to the middle Nearer the medial plane. Lateral Pertaining to the side away from the mid-plane. Proximal/Distal - from tip of an appendage (distal) to where it joins the body (proximal).
