BOF 9
When investigating the nervous system, all are wrong, except:
1-seeing the posterior cranial fossa is better with CT scan
2-MRI is poor in visualizing the white but not grey matter of the brain
3-the orbit is better seen by CT san
4-the MRI has an advantage of avoiding ionizing radiation
5-the carotid Doppler study has a very low inter observer variability

Answer: 4
1-false, many bone artefacts would interfere with the picture
2-false, both are excellently seen
3-false, MRI gives better details
4-true …..but should avoided in claustrophobic people
5-fasle, unfortunately, it is highly operator dependent
