used as a simple method to image calcium. May be used to check for metal before MRI
radiograph (x-ray)
on a radiograph, what is radiodense? what is radiolucent?
radiodense - bone, appears white
radiolucent - air, appears dark
when interpreting a radiograph, what structure do you look for?
pineal gland
x-ray of cerebral vessels with contrast
cerebral angiography
rotates an x-ray beam around the head. distinguishes tissue density
computed tomography (CT)
CT brain window vs bone window
bone window - good for imaging bone, bleeding. detailed skull, everything else gray.
brain window - good for imaging brain (except posterior fossa). more detailed (shades of gray) brain, less detailed but bright white skull.
magnetic field + radio wave pulse
MRI
MRI is great for imaging what structures
spinal cord and posterior fossa
bright skin, dark bone.
hyperintense brain, hypointense fluid
MRI T1
dark skin/bone
hyperintense CSF/blood, hypointense brain
MRI T2
dark skin/bone. hyperintense brain, hypointense fluid
MRI FLAIR
noninvasive angiography, can be done with or without contrast agent
MR angiography
gadolinium: radioactive or non-radioactive?
non-radioactive
detects blood flow or metabolism in any part of the brain. patient injected with radioactive glucose
PET scan
used to image a fetus’ brain
