9: MRI Spine Flashcards
What is the level of Carotid Bifurcation
C3 C4
3 arterial branches originating from the Aortic Arch:
- Brachiocephalic
- Left Common Carotid
- Left Subclavian
Supplies oxygenated blood to the brain:
Internal Carotid Artery
Supplies oxygenated blood to the superficial structures of the face and head:
External Carotid Artery
Supplies oxygenated blood to the posterior vertebral region and posterior region of the Circle of Willis via the Basilar Artery:
Left and Right Vertebral Arteries
The formation of a bulb-like protrusion of arterial wall due to weak arterial walls:
Aneurysm
The result of blood obstruction in Carotid or COW resulting in mild facial symptoms and retardation also known as Bell’s Palsy.
Transient Ischemic Disease
Is the narrowing of space within an artery of vein limiting the flow of blood.
Stenotic disease
The condition in which the arterial wall splits internally causing blood to become blocked.
Dissection
The anatomical structure encompassing the spinal cord with CSF:
Thecal Sac
The leak of annulus causing a protrusion or bulging of intervertebral disc, thus causing neck pain or/and shoulder and arm radiocular symptoms
Cervical Herniated Nucleus Pulposus
An abnormal fluid-filled canal linearly in spinal cord normally found within the cervical region:
Syrinx
Burst C1 fracture of the lateral masses; typically caused by driving head first into shallow water:
Jefferson fracture
Bilateral pedicle and lamina C2 fracture; typically caused by high velocity hyperextension injury (MVA)
Hangman fracture
C7 Spinous process fracture; typically caused by sudden, intense muscle contraction.
Clay Shovelers fracture
