Module 9 Flashcards
VFA
Vertebral fracture assessment
What are other names for VFA
RVA
IVA
DVA
LVA
What is the area of region for A
VFA
Fourth thoracic vertebrae to the 5th Lumbar vertebrae
What type of fractures are particularly highly predictive of future fractures
Vertebral fractures
What percentage of verterbal fractures found on imaging exams ever exhibit clinical indications
30%
True or false pts with low bone mass but no prior fragility fractures are at lower risk than patients with a high bone mass and previous fragility fracture
True
What is the most common osteoporotic break
Vertebral compression fracture
The ISC D States that the vertebral fracture information should be collected if the T score is less than
Negative 1.0 and 1 more other qualification
Name the other qualifications for a veterbal fracture information to be collected
Women older than 70 or men older than 80, a height loss of more than 4 cm or 1.57”, a self reported vertebral fracture that was not medically documented, and glucocorticoid therapy equivalent to the 5 mg of prednisone daily for more than 3 months
What is the average dose for DXA
3 to 40 mSv
Where’s the most common sight for a vertebral fracture
T11 through L1
Where is the 2nd most common Site for a vertebral fracture
T7 through T8
This is a semiquantitative method for vertebral fracture evaluation
The Genant System
This approach compares the anterior medial and posteroir vertebral height with the height of a normal vertebrae
The Ganant system
Mild fractures exhibit what percentage reduction in vertebral height
20 to 24%
Moderate fractures have an average decrease in height of
25 to 39%
Severe fractures mostly present with what percentage of height reduction
40% or greater
Anterior vertebrae fractures are described as
Wedge shape
Middle Vertebrae fractures are specified as
Biconcave
Posterior vertebral fractures are considered
Crushed shape
Quantitative morphonetric analysis uses how many vertebral points for measurement
6
What are some incidental pathological findings seen on VFA
Abdominal aortic classifications
What is the most commonly misdiagnosed vertebral deformity
Physiological wedging
If vertebral height is not reduced by more than 20% of expected findings, than the clinician can suspect blank is unlikely
Physiological wedging
This disease presents as remarkable kyphosis of the Thoracolumbar spine. Must show more than 5ﾟ of i
anterior wedging in at least 3 neighboring vertebrae for diagnosis
Scheurmanns disease
These are end plate depressions that are well rounded. They often have a sclerotic border and involve only a portion of the end plate
Schmorls nodes
This disease often occurs in older adults and is caused by weakening vertebral facet joints. This leads to lateral curvature of the spine and rotational obliqueness
Degenerative scoliosis
This deformity most often affects the inferior end plates of the L4 and L5 vertebrae.
Cupid’s bow
Compression fractures are most often found at
T11 through L1
Which vertebrae are most often affected by Cupid’s bow deformity
L4 and L5
Where should the bone density technologist begin counting vertebrae
L5
