All follow up DXA scans ought to be as compared to the ________scan - ANS-baseline
Although the generation is similar with all of the DXA devices, the BMD results are
extraordinary because.......... - ANS--exclusive calibration requirements
-algorithms to calculate BMD
-differences in the ROI
-different databases
Aluminum Phantoms - ANS--used with Prodigy, DPX-NT and DPX-MD+
constantly select the bottom T-score to make a prognosis - ANS-
An increase within the common bone mass of a affected person is intently associated with
an expanded price of bone ___________ and a discounted amount of _______________. -
ANS-formation; resorption
Anabolic Agents - ANS-stimulates osteoblastic formation
Antiresorptive Agents - ANS-inhibits osteoclasts
, Aphasia - ANS-general or partial lack of the power to apply or apprehend phrases
Appendicular skeleton - ANS-pelvic girdle, limbs, palms and feet
Areas of the frame wherein cortical (compact) bone is discovered) - ANS--femoral neck
-hands
-proximal forearm
-distal forearm
Areas of the frame where trabecular (cancellous) bone is observed - ANS--spine
-Ward's Area
-calcaneus
-ultradistal forearm
As _______ will increase, the chance for a hip fracture will increase impartial of the BMD -
ANS-HAL (hip axis duration)
As age increases every 10 years Relative Risk multiplies through 2 - ANS-
As BMD decreases by using 1 SD Relative Risk is increased by way of 2 - ANS-
At excessive power (more than 70 kev) what attenuation is extra? - ANS-soft tissue
At low electricity (30-50 kev), what attenuation is wonderful? - ANS-bone
Atypical Subtrochanteric and Femoral Shaft Fractures - ANS--uncommon types of fractures
-greater common in sufferers taking bisphosphonates
-pain in thigh precedes fracture
Axial Skeleton - ANS-skull, vertebral column, and thoracic cage
Biochemical Marker Test - ANS--facilitates decide if bone is being misplaced at a faster fee
than ordinary
-can also decide if one is responding to bone loss remedy pills
Bisphosphonates - ANS--prevents development of osteoclasts
-incorporate 2 phosphate groups
