Calcitonin |- |ANSWER✔✔✔--Hormone |Treatment |for |Osteoporosis |that |forms |naturally |in |the |
thyroid. |
-It |can |be |used |to |increase |bone |mass |moderately. |
-Used |to |decreas |the |rate |osteoclasts |absorb |bone. |
-Can |only |be |given |to |postmenopausal |women |of |5 |years |or |more
Regions |of |Interest |(ROI) |- |ANSWER✔✔✔-The |area |selected |for |bone |density |scanning |and |the
|area |where |the |calculation |of |the |BMD |occurs.
Components |of |DXA |- |ANSWER✔✔✔-Workstation |unit, |phantom |and |positioning |equipment, |
k-edge |filtration, |and |energy |switching |system.
,DXA |Workstation |Components |- |ANSWER✔✔✔-Display |monitor, |computer, |keyboard, |mouse, |
printer, |power |module
Juvenile |Osteoporosis |- |ANSWER✔✔✔--Diagnosed |in |children |8-14
-Patient |may |experience |normal |gonadal |functioning, |rapid |onset |of |parin |in |the |bones, |or |
sustain |a |fx |from |a |traumatic |event
Pencil |Beam |- |ANSWER✔✔✔--Scan |time |5-10 |minutes
Laser |Radiation |- |ANSWER✔✔✔-A |laser |is |used |to |effectively |position |scanner
L-spine |- |ANSWER✔✔✔--Point |on |the |spine |that |curves |(Lordotic |Curve)
-3 |Main |parts |(Arch, |processes, |body)
DXA |Scan |- |ANSWER✔✔✔--Can |measure |multiple |aspects |related |to |the |bone, |BMC, |BMD, |fat-
free |mass, |and |estimates |the |body's |fat |percentage. |Any |changes |to |the |mode |geometry |can |
impact |measurements.
Nucleus |- |ANSWER✔✔✔--Found |inside |the |intervertebral |discs
-Gel |filled |center
Ulna |- |ANSWER✔✔✔--Has |long |and |curved |appearance
-Allows |motion |and |supports |arm
-Attaches |to |triceps |brachii, |supinator, |pronator |teres, |pronator |quadrates, |flexor |digitorum |
superficialis
-Has |Trochlear |Notch, |Coronoid |Process, |Olecranon |Process
, Head |of |Radius |- |ANSWER✔✔✔--Disk |Shaped
-Proximal |end
-Articulates |with |Radial |Notch |of |Ulna
Proximal |Femur |Positioning |- |ANSWER✔✔✔-The |Midline |needs |to |be |perpindicular |with |the |
neck |box
Proximal |Femur |ROIs |- |ANSWER✔✔✔-Trochanteric |region, |Ward's |region |(triangle), |the |neck, |
and |Shaft
Cross-Calibration |- |ANSWER✔✔✔--Calculates |and |compares |changes |between |the |initial |and |
new |DXA |machines
-Studies |are |considered |as |in |vivo |and |in |vitro(use |phantoms)
-Studies |are |used |for |new |machins |and |60-100 |phantoms |are |used |to |establish |a |baseline |
measurement |for |BMD
BMC |- |ANSWER✔✔✔--Calculated |by |BMD |and |Area
-BMD(g/cm2) |x |Area(cm2) |
-BMD(mg/cm2) |x |Volume(cm3) |-- |QCT
External |Quality |Control |- |ANSWER✔✔✔--Facilities |are |given |samples |and |asked |to |process |
them |as |they |would |their |own |and |are |then |checked |by |the |main |facility. |
-Takes |longer |but |more |accurate |results
-Requires |calibrated |test |weight
Internal |Quality |Control |- |ANSWER✔✔✔--Having |a |group |of |activities |performes |by |the |facility
|to |ensure |that |equipment |and |staff |are |working |properly |in |the |set |limits.
-Quicker |with |less |accurate |results
