What 2 types of imaging are non-ionising?
USS and MRI
X-rays:
What are some advantages? - 3
What are some limitations? - 3
Low amount of ionising radiation to obtain image
Cheap and quick
Good contrast between bone, soft tissue and lung and air
Ionising radiation (Pregnancy)
Poor differentiation between soft tissue as the brain or muscle
2 dimensional image
USS:
What are some advantages? - 3
What are some limitations? - 3
Real time imaging (biopsies)
No ionising radiation
Inexpensive
Operator dependent
Limited to certain body sites - unable to scan through bone or air
Difficult for obese patients
CT:
What are some advantages? - 3
What are some limitations? - 2
Rapid acquisition of data
Inexpensive
3D
Ionising radiation
Subject to artefacts due to patient movement
