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
The distal bulb-like portion of the spinal cord:
Conus Medullaris
At T12 - L1, the caudal medullaris tapers into a collection of neural roots called:
Cauda Equina
Curvature of the spine; can be categorized as rotatory or idiopathic:
Scoliosis
HNP
Herniated Nucleus Pulposus
A leak of annulus causing a protrusion or bulging of intervertebral disc, thus causing midback pain or/and rib radiocular symptoms
Thoracic Herniated Nucleus Pulposus
Found predominately in elderly females with osteoporosis:
Confirmation of Compression Fractures
A surgical procedure that percutaneously (through the skin) injects cement to fill space within a compression fracture:
Kypholasty
Rare condition showing presence of TB in musculoskeletal structure; found normally in Thoracic region:
Pott disease
Rare condition showing juvenile kyphosis in the thoracolumbar region:
Scheuermann Disease
Idiopathic scoliosis
Spontaneous
Rotary Scoliosis
Curve and twisting in of vertebrae
Common in swimmers and baseball players:
Pars Interarticularis injury
Visualized on a STIR sequence; this injury is predominately found in swimmers and baseball players (slides head first) due to excessive hyperextension of the lower back.
Pars Interarticularis injury
A leak of annulus causing a protrusion or bulging of intervertebral disc, thus causing lower back pain or/and buttocks, leg and foot radiocular symptoms.
Lumbar Herniated Nucleus Pulposus: HNP
The narrowing of the spinal canal causing radiculopathy symptoms:
Lumbar Stenosis
Cysts located in the neural foreman causing impingement of a nerve root:
Lumbar Facet Cysts
The forward displacement of the L5 vertebral body; may be due to facet dislocation or fracture:
Spondylolisthesis
Osteoarthritis within the facet joints:
Spondylosis
The angulated view to visualize the sacrum in-plane:
“Shovel Shot”
To properly angle for the “Shovel Shot”, tilting the coronal sacral image ____ on a sagittal image.
15 degrees
Fractures caused by physiological stress on a weakened bone. Commonly found in patients with osteoporosis:
Insufficiency fracture
Inflammation of the sacrum that emulates lower back pain, higher tendency to be present in patient’s with Rheumatoid Arthritis.
Sacroiliitis
Progressive cartilage degeneration of the sacroiliac joints:
Osteoarthritis of the Sacroiliac joints
