1 Neuroimaging spine / spinal cord

2 Spine & spinal cord imaging methodology Plain x-ray of spine Computed tomography CT - traditional ( normal CT) - reconstructions - myelo-ct Magnetic resonance MR - standard techniques Angiography - DSA

3 Cervical spine x-ray post-traumatic injuries & degenerative disorders

4 Lumbar spine x-ray post-traumatic injuries & degenerative disorders

5 Myelography is a history

6 CT was a great progress in spine and spinal cord imaging

7 Myelo-CT was very important before - MRI came to clinical practice

8 Nowadays CT

9 Spine MRI spinal canal / spinal cord

10 Spine MRI spinal nerves

11 1. Congenital spine & spinal cord defects developmental anomalies heterogenic group of disorders selected exaples below

12 cervical vertebral bodies in block os odontoideum

13 Meningeal Cysts (Tarlow cysts)

14 Meningeal hernia

15 Hydromyelia Syringomyelia

16 Captured spinal cord combined anomaly - broadened terminal filament - no conus of spinal cord - fibro-lipoma in spinal canal - spina bifida - Tarlow cyst

17 2. Demyelinization diseases multiple sclerosis M S

18 Spinal cord demyelinization MS

19 MS plaques in cervical spinal cord

20 Focal lesion in cervical spinal cord demyelinization or tumor (neoplasm)?

21 3. Spinal canal tumors extra meningeal intra-meningeal, extra-medullary intra-medullary (intra-axial)

22 Spinal canal tumors extra-meningeal benign: neurinoma, osteoma, fibroma, lipoma malignant: osteo - & chondrosarcoma, chordoma, lymphoma metastases Fibrolipoma

23 Spinal canal tumors extra-meningeal neurinoma (schwannoma)

24 Spinal canal tumors intra-meningeal / extra-medullary naurinoma, neurofibroma meningioma lipoma, teratoma (seldom)

25 Spinal canal tumors intra-meningeal / extra-medullary neurinoma dumbbell tumor

26 Intra-medullary tumors astrocytoma (most frequent) ependymoma, hemangioma metastases

27 Intra-medullary tumors (intra-axial)

28 Intra-medullary ependymoma

29 Vertebral spine and spinal canal metastases

30 Spinal cord hemangioma intra-medullary focal lesion nidus pathologic vessels in spinal canal (intra-meningeal)

31 4. Degenarative spinal disease discopathy bone degeneration

32 Intervertebral disc prolapsus with spinal nerve compression

33 L-S discopathy L4-L5 & L5-S1 levels massive left-side disc protrusion L5-S1 spinal nerve compression

34 Intervertebral disc protrusion - MR from I to IV degree

35 Intervertebral disc sequestration prolaps of a disc to spinal canal

36 Spinal canal stenosis discopathy coexisting with bone degeneration (ostephyte) spinal nerve compression

37 Spine degenerative disease - complications inflamed process in vertebral bodies border laminas spondylodiscitis non-stability L5 vertebral body slide down spondylolisthesis

38 Dyscopathy recurrent after operation contrast enhencement after paramagnetic administration connective tisue scar

39 Cervical spine discopathy spinal canal stenosis C5-C7 - meninges and spinal cord compression - stenosis of right intervertebral foramen

40

41 Chronic spinal cord compression - focal gliosis at the level of compression - central canal of a cord broadening

42 5. Spine & spinal cord injuries solitare spinal fractures injuries with spinal cord compression pathologic fractures

43 Spine injuries compressive fracture of vertebral body one of the most frequent?

44 compressive fracture of vertebral body CT in 3 dimentions

45 Spine injuries compressive fracture of vertebral body not very harmful when stabile & does not affect neurostructures

46 Spine and spinal cord injuries vertebral body compressive fracture with spinal cord compression

47 Chance fracture spinal cord compression

48 Spine and spinal cord injuries - pathologic fracture of vertebral body (meta) - compression of spinal cord conus

49 Spine and spinal cord injuries pathologic fracture of vertebral body (osteoporosis) hardly seen on plain x-ray films

50 Cervical spinal cord injury most frequent - water jump

51 Cervical spinal cord injury whiplash mechanism or rear-end MVA

52 skull base fracture fracture of dens axis
