2. Goals Identify axial, sagittal, and coronal images Identify the following: –CT head without contrast –CT head with contrast –MRI brain Identify the following MRI sequences –T1 –T2 –T2 FLAIR –T1 + contrast –Diffusion Weighted Images

3. Right Left Nose

6. Fluid is dark, air is darker Bone is white

7. Grey matter is light White matter is darker Blood and Calcium are white Fluid is dark, air is darker Bone is white

9. T1 T2 FLAIR T2 Diffusion T1 + Contrast

11. CSF if white Grey matter is lighter White matter is darker Most pathology is white or hyperintense

12. CSF if white Grey matter is lighter White matter is darker Most pathology is white or hyperintense

14. CSF if black Grey matter is lighter White matter is darker Most pathology is white or hyperintense

15. CSF if black Grey matter is lighter White matter is darker Most pathology is white or hyperintense

17. CSF if black Grey matter is darker White matter is lighter

18. CSF if black Grey matter is darker White matter is lighter Sometimes, pathology can be seen as “black holes”

20. CSF if black Grey matter is darker White matter is lighter Blood vessels light up

21. CSF if black Grey matter is darker White matter is lighter Blood vessels light up

23. Ghostly Ethereal You can’t really see the skull or soft tissues of the head Pathology is white

24. Ghostly Ethereal You can’t really see the skull or soft tissues of the head Pathology is white

25. How to Figure it out Fast Big white rim of bone = CT scan.

26. How to Figure it out Fast If CSF is white, it has to be T2

27. How to Figure it out Fast If it’s ghostly and ethereal, it has to be Diffusion

28. How to tell T1 from T1 + Contrast Ahem

29. How to tell T1 from T2 FLAIR Both have black CSF T1 is smoother T2 is grainier T1 has dark cortex and light white matter T2 has light cortex and dark white matter TR – 500TR – 10,000
