7 Steps of Neurosurgery Ultrasound Scanning,Alex Fan,Asia clinical application & KOL manager,General advice,Previous surgery and radiotherapy can cause difficulties using ultrasound in the brain or spine.,The bone opening must be large enough to accommodate the probe.,Good acoustic contact requires the use of sterile ultrasound gel or saline between the probe and brain/dura.,If available, connection to Brainlab navigation will allow faster and more intuitive orientation.,7 steps of Neurosurgery US Scanning,Enter patient ID,Recognize patients position,Select probe & preset,Set frequency,Identify,left side of probe,Recognize ultrasound images,Three planes of brain,Patients position is crucial,Typical CT/MR scan,Ideal position for US scanning,Select probe & preset,Craniotomy probe: 8862,Burr-hole probe: 8863,“,Hockey stick,”,probe: 8809,Set frequency,Default setting is 8MHz,Deep,Peripheral,Identify left side of probe,Recognize ultrasound images,Echogenicity,Hyper-echoic,Iso-echoic,Hypo-echoic,Homogenicity / Uniformity,Homogenous / Uniform,Heterogenous / Nonuniform,Shape,Regular,Irregular,Border,Clear / Sharp,Unclear,Recognize ultrasound images,Echogenicity,Hyper-echoic,Iso-echoic,Hypo-echoic,Recognize ultrasound images,Homogenicity / Uniformity,Homogenous,/ Uniform,Heterogenous,/ Nonuniform,Recognize ultrasound images,Shape,Regular,Irregular,Recognize ultrasound images,Border,Echogenicity Homogenicity,Hypoechoic,Isoechoic,Hyperechoic,Homogenous,Heterogenous,White mater,X,X,Grey Mater,X,X,X,Ventricle,X,X,Sulci,X,X,Choroid Plexus,X,X,Brainstem,X,X,Normal Brain,Grey matter,White matter,Sulci,Falx,Normal,Brain,Gyrus,Sulci,Choroid Plexus,ventricle,Three planes of brain,Horizontal,Coronal,saggital,Three planes of brain,Most commonly used in daily work. Horizontally put the probe on the surface of brain tissue after remove part of skull, then you can have typical horizontal plane.,Different images on different levels,。,Horizontal plane,Anterior horizontal plane,Anterior lateral ventricle,Temporal window horizontal plane,Occipital horizontal plane,Levels of horizontal plane,Cortex level,Lateral ventricle level,4,th,ventricle level,Brainstem level,Cortex level,1: Cerebral Falx,2: Sulci,3: Gyrus,1,1,2,2,3,3,Lateral ventricle level,1,1,2,2,1,、,Cerebral Falx,2,、,Lateral Ventricle,4th ventricle level,3,3,1,1,1,1,2,2,3,3,4,4,Brainstem level,1,3,3,2,2,2,1,1,、,Cerebral falx,2,、,Brainstem,3,、,Lesion,Sagittal plane,Sagittal plane,1,:,Lateral Ventricle,2,:,Choroid plexus,3,:,Ventriculus tertius,4,:,Corpus callosun,6,:,Gyrus 7,:,Sulci,Sagittal plane,3,5,5,4,4,3,1,1,2,2,1,、,Lateral ventricle,2,、,Corpus callosum,3,、,Choroid plexus,4,、,Gyrus cinguli,5,、,Lesion,Vertex Coronal plane,Vertex Coronal plane,1,:,Lateral ventricle,2,:,Choroid plexus,3,:,Ventriculus tertius,4,:,Cerebral falx,Vertex Coronal plane,3,1,1,2,2,2,2,4,4,5,5,3,1,、,Cerebral falx,2,、,Lateral ventricle,3,、,Base of skull,4,、,Optic chiasma,5,、,Lesion,Temporal coronal plane,Temporal coronal plane,Thank You,
