Anyone got some extra info on this dot point in the second column of the syllabus?
'Explain why MRI scans can be used to
*Detect cancerous tumours
*Identify areas of high blood flow
*Distinguish between grey and white matter of the brain'
The key work there being 'why'...i know that detection of blood flow is related to hydrogen atoms etc but i haven't found much detailed info about the other two points...
OR am i just looking too deeply into this and i basically just have to repeat myself bout MRI functions???
