- neuroimaging
- structual
- Computerised Tomography
- pros
- non invasive, useful for locating brain injures & abnormalities
- cons
- XRAYS emit radiation, black and white only show structure, not function
- prodcues a high resoultion 3-D computer image of the brain. contrast idoine to highlight blodd vessels, xrays "slices", detects tumpurs, brolken bone etc
- pros
- Magnetic Resonance Imaging
- pros
- clear pictures, non invasive, no radiation
- cons
- EXPENSIVE, can't be used by people with metal implants; pace makers, articals hips etc
- uses magnetic fields and radio waves to produce a computer-enhanced image of the brain structure, provides a highly detailed image
- pros
- Computerised Tomography
- functional
- Position Emission Tomography
- pros
- shows function. red = high, blue = low
- cons
- PET is less detailed than an MRI, requires an injection of a radioactive trace
- injected with a radioactive isotope, mainly measures functional changes, increased blood flow & glucose consumption for "busy" parts of the brain
- pros
- Functional Magnetic Resonance Imaging
- pros
- no injections, allows for a combo of functional & structural
- cons
- process time can be consuming to collect images
- measure oxygen consumption across the brain, this technique uses the fact that blood is more oxygenated
- pros
- Position Emission Tomography
- structual
