The introduction of sectional anatomy

1. The introduction of sectional anatomy The medical college of shandong university

2. The forest clinician Where is the direction of medicine ！？

3. Follow me ！！！ clinician imaging doctor

4. Medical image period !!

5. E – hospital !!!

6. The history and status of sectional anatomy • the first stage(16-18 century): • da Vinci, A.Vesalius • the second stage (19-20 century): • Pirogoff 和 Eycleshymer & Schoemaker • the third stage ( since the 70age of 20century): • the sectional anatomy be get greatdevelopment

7. da Vinci（1452 -1519）

8. The picture is painted by da Vinci

9. The A.Vesalius is dissecting in church （1514-1564）

10. The definition and feature of sectional anatomy the sectional anatomy is the science of studing the shape、position、adjacent and functions in series section of human beeing.it,s task is serveing CT、MRI 、US.

11. it differents from systematic anatomy and regional anatomy： 1. to keep the structure in originenal position；

12. 2. to perform the three-dimensional reconstruction by sectional structure；

13. the three-dimensional reconstruction of cerebral vessels

16. the three-dimensional reconstruction of heart

17. the three-dimensional reconstruction of coronary artery

18. CE-MRA—dissection of aorta

19. CE-MRA—abdominal aneurysm

20. the three-dimensional reconstruction of blood vessel

21. the three-dimensional reconstruction of bone

22. the three-dimensional reconstruction of bones of foot

23. the three-dimensional reconstruction of scapula

24. the three-dimensional reconstruction of axis

26. the three-dimensional reconstruction of small intestine

27. the three-dimensional reconstruction of blood vessel

28. the three-dimensional reconstruction of fascia

29. 3. to combine with the medical image closely.

30. the transverse plane pass through 10th thoracic vertebra (superior view)

31. the transverse plane pass through 10th thoracic vertebra (inferior view)

32. The sagittal section of cranium (left view)

33. The coronal section pass through ascending aorta

34. Supraorbitomeatal line Canthomeatal line Infraorbitomeata line（Reid ,s base line） Horizontal line The scanning by vertical axis

35. AC-PC line

36. Talairach 坐标系

37. The structure of cranium is very complex, so we want get the clear image ，to apply scanning lines as below: 1. Supraorbitomeatal line midpoint of external auditory meatus supraorbital margin

38. 2. infraorbitomeata line （Reid ,s base line） midpoint of external auditory meatus infraorbital margin

39. 3. Canthomeatal line midpoint of external auditory meatus lateral angle of eye

40. 4.Intercommissural line (AC-PC line) Anterior commissure posterior commissure

41. The CT is scanning

44. The transverse scan of cranium by MRIT1

45. The transverse scan of cranium by MRIT2

46. The median sagittal scanby MR MRI T1 WI

47. The median sagittal scanby MR MRI T2 WI

48. The sectional specimen MRI T1 The coronal section pass through internal capsule

49. MRA

50. 磁共振脑纤维束成像 八十年代初，国、外便开始颅内水扩散成像的生化研究。该技术成为活体上测量水分子扩散运动与成像的唯一方法，最常用的是: 扩散加权成像（DWI）和 扩散张量成像（DTI）， DTI可三维显示正常脑纤维束的走行、年龄变化，因病变造成的纤维束受压、移位、变形、浸润与破坏。较常规MRI能更好地观察肿瘤与周围纤维束的关系，用于诊断脑纤维束溃变、脑白质疏松、脑缺血性病变、颅内肿瘤等。
