Densitometry Bone iyo lafo - fursad kale si aad u ogaato ka hor ku saabsan cudurka

Osteoporosis - cudurada, taas oo lafaha lumin calcium, oon ku noqday debcaan. Haddii ay jirto arrin ka yaraan argagaxa ay deform karaa ama jebin. Si qalad ah ay aaminsan yihiin in cudurka dhacdaa in dadka jidhkooda ku jira xaddi aan ku filnayn ee calcium. Tan dhab ma aha. Osteoporosis yeesho xataa la xad-dhaaf ah oo xubno ka raad ee cuntada. Sababta nugulsanaanta lafta kordhay waa nuugista ku filnayn lafaha calcium ama "washout".

etiology ee osteoporosis

cufnaanta ee lafta ku xiran tahay xaddiga hormoonnada jinsiga. In ragga, testosterone badan haweenka, si lafahooda waa badan sii dhumuc weyn oo xoog badan. Sidaas darteed, osteoporosis waxaa badanaa la baaraa ee dumarka, gaar ahaan dayska, maxaa yeelay, wakhtigaas heerka hoormoonka waxaa si weyn u dhimay.

Ka mid ah sababo kale, waxaa in la xuso in osteoporosis hypodynamia, la'aanta vitamin D, oo aan khamri cabbaynin, sigaarka, jiritaanka cudurada raaga (diabetes, lesions thyroid, cudur ku raagay beerka iyo kelyaha).

Sida loo aqoonsado osteoporosis?

Haddii qof ayaa sheegay in daal iyo lafaha xanuun, isbeddel ah ee qaab iyo wiiqmin, timaha oo daata iyo sii daraysa ee ilkaha, iyo sidoo kale jab joogto ah, waxaa lagu talinayaa in la sameeyo densitometry. Tan waa baaritaan deg deg ah oo aan xanuun lahayn gabi ahaanba u ogolaanaya in la qeexo oo qiyaas khasaaraha ka mid ah cufnaanta lafaha iyo content macdanta in la dhiso oo la qiimeeyo halista oo jab ah. Tani waa habka baaritaanka ugu xasaasi for ogaanshaha hore ee osteoporosis.

Nuxurka of densitometry waxaa candling lafta aan la arki karin X-rays. Xaaladdan oo kale, u isticmaal kuuro hooseysa oo ionizing shucaaca ka samatabbixiyey qaab laba socodka tamarta, kaas oo u ogolaanaya si loo baaro si degdeg ah oo sax ah.

Waxaa la xusay in densitometry lafta lagu gartaa dose shucaac ah, kaas oo hoos u dhigay ugu yaraan (waxay ka yar tahay 1/10 ee dose ah in bukaanka helay inta lagu guda jiro raajada feeraha caadiga ah).

Marka waa densitometry ah

Tilmaamayaasha sahanka waxa ay kala yihiin dalalka soo socda:

• dayska hore ama dayska, taas oo dhacda in dumarka soo socda la joojiyo caadada;
• joogitaanka of kelyaha,
• cudur beerka ku gaamuuray;
• daaweyn muddo dheer la glucocorticoids;
• nafaqo syndrome nuugeynin, taas oo horseedaysa deficiency calcium,
• densitometry lafta waxaa sidoo kale laga sameeyey joogitaanka arthritis rheumatoid, hyperparathyroidism iyo hyperadrenocorticism iyo sidoo kale in hypothyroidism iyo sonkorowga.

Haddii ay jiraan jab dhaawacyada yar yar, waxa ay sidoo kale waa calaamad muujinaysa sahanka ah. Waxaa la rumeysan yahay in xadgudub ka dhan ah daacadnimada lafaha ee osteoporosis yaraynaysaa rajada nolosha bukaannada ka sii badan kansarka ah, sidaas ogaado waqtiga cudurka waa mid aad u muhiim ah. Waa in la ogaadaa in mararka qaarkood soo bandhigid dhaxlay noocyada cudurada this.

densitometry Bone: Key

Waxaa jira habab kala duwan oo lagu ogaan karo osteoporosis, laakiin isticmaalkoodu yahay mid aad u kooban. Sayidka, beddelka kala duwan ee MRI waa qaali, si raajito loogu xisaabiyaa tirada siinayaa sare dose of shucaaca, daraasadda of indices lagmamaarmaanna u khuseeya shiid lafta lagu gartaa kala duwanaansho weyn ee xogta sharciyeed, oo bukaanku uu raaxo marka lafihii biopsy. Marka waa cudurka of osteoporosis, densitometry waa habka ugu caansan.

Waxaa loo adeegsaday saddex farsamooyinka ugu muhiimsan in la si gaar ah loogu talagalay ogaanshaha cudurka this:

• absorptiometry X-ray,
• Ultrasound densitometry;
• raajito loogu xisaabiyaa durugsan (uu leeyahay khasaare weyn - aan u oggolayn in la qiimeeyo xaaladda ka mid ah lafaha qalfoofka axial).

Wixii doorashada saxda ah ee habka cilmi-baarista iyo qiimeynta saxda ah ee natiijada tixgeliyaan ku dhegyadii ee daliilka kiliinikada. Sidoo kale xisaabta lagu darsadaa shuruudaha ogaanshaha khuseeya.

Mabaadi'da qiimaynta natiijada densitometry

Si ay u sharxaan xogta sahanka helay ka dib markii dheer "osteopenia" ama isticmaal "osteoporosis". Waa in aan loo tixgalin in sida cudurka daawayn, laakiin kaliya sida calaamad u ah in la socon kartaa wax kasta oo nabar lafaha la hoos cufnaanta. Waa in la ogaadaa in densitometry lafta looma fuliyo for ogaanshaha sax ah iyo in la ogaado bukaan halis ugu jab.

Iyada oo qalab software this (densitometer) barbardhigay natiijada helay iyo database a la doortay, iyo faraqa u tira waa. Waxaa lagu go'aamiyaa tirada leexashooyinkaasi Heerka dhalaa magaca T-test (loo isticmaalo in lala barbardhigo dadka dhallinyarada ah oo isku jinsi ah sida bukaanka) ama imtixaanka Z (is barbar dhig, qaadataa koox dad ah ee da'da ku habboon, galmada iyo miisaanka).

Haddii T-baaritaanka ma aha in ka badan 2,5 SD, taas oo u dhiganta osteopenia, haddii natiijooyinku hoos tiradaasi, mid ka mid ah ku hadla ee osteoporosis. qiimayaashan waxaa loo tixgeliyaa "marinkii." Tani waa in la tixgeliyaa in fasiraad sax ah oo ah natiijada densitometry.

densitometry X-ray

Farsamo ahaan, iyadoo la kaashanayo cindiga X-ray sahamin karaan ugu lafaha. Sida caadiga ah lagu qabtay densitometry dhabarta (uu dhabarta lumbosacral) iyo misigta, halkaas oo inta badan soo koraya jab in osteoporosis. Sidoo kale ogaado cufnaanta bowdada iyo gacanta densitometry unugyada lafta ama ku qaataan jirka oo dhan. Tani waxay u ogolaaneysaa baaritaan si loo ogaado waxa ku jira macdanta ee aagag la xushay ee jirka ama jidhka oo dhan.

In la soo dhaafay ee qiimaynta mass laftayda iyo content macdanta xeryahooda la isticmaalay habka isotope absorptiometry, mabda'a ah oo ka kooban in tiriska walxaha gamma ah iyo qiimaynta heerka ay nuugista. khasaaro muhiim ah oo baadhitaan noocan oo kale ah waa fur shucaaca la taaban karo. Ka dibna waxay bilaabeen in ay isticmaalaan laba-photon absorptiometry x-ray, kaas oo ahaa heer sare ah oo xasaasi ah oo ka yar waxyeelada bukaanka. Si aad u taariikhda, waxa ku caawin kara garto% ka mid ah lumista lafta kaliya 2-3, sidaas sahankan loo isticmaali karaa baaritaanka dumarka dayska, waayo, goor hore la ogaado osteoporosis.

ultrasound densitometry

Noocan ah baadhitaan la fuliyaa si ay u qiimeeyaan xoog lafaha. Tani waxay xisaabta ku cufnaanta, microstructure iyo barti, iyo sidoo kale dhumucda lakabka cortical. Faa'iidada muhiim ah, sahanka noocaan ah - maqnaanshaha gaadhista shucaaca. Fiirsaneysa inay ammaanka nidaamkan, waa la soo celin karaa oo aan wax xayiraad.

Waa in la sheegay in densitometry noocan oo kale ah waxay ku salaysan tahay awoodda ay hirarku ultrasonic dacaayad ay weheliyaan dusha sare ee lafta, ama kala firdheen oo nudaha lafaha. Xaaladdan oo kale, waxaa suurto gal ah si loo ogaado barti, cufnaanta iyo qallafsanaan ee lafta.

Waa in la ogaadaa in densitometry ee lafta ultrasonic waxaa loo isticmaalaa oo kaliya u ah baadhista lafaha durugsan. Inta badan, habkan baaray ee ciribta iyo soo gaaray, patella, ama phalanges. Inta badan alaabtii loo ogaado xawaaraha faafinta ultrasonic ama attenuation, taas oo muujinaysaa oo keliya ma aha on cufnaanta lafaha, laakiin sidoo kale on helitaanka micro ama trabecular.

gunaanad

Ayadoon sida osteoporosis waxaa lagu daaweeyaa (foomka of calaamad ama cudur), densitometry ogolaanaya si loo ogaado khatarta ah in jab. Waa in la xusuusnaado in doorashada ee aagga sahanka waa mid aad u muhiim ah, sababtoo ah degsiimooyin ka mid ah lafaha mineralized ama laga yaabaa in aanay isku mid u ah lafaha oo dhan u noqon.

Si sax ah u doorato, waxaad u baahan tahay in la ogaado astaamaha soo socda:

• walax trabecular saameeyeen ee syndrome dhaleysnimada ama dheelitir la'aanta steroid hypogonadal;
• dhaawac ahaaneed si ay lafta cortical lagu arkay neefo, hyperthyroid, osteoporosis diabetic;
• haddii bukaanka ee carruurnimada ama qaan yeesho cudur aan faragalin ku koritaanka lafaha, lafaha laga helaa cilado systemic. Waxay waxaa weheliya dhaawac labada layers lafaha.

Waa in aad ogaato in ay jiraan isbedel of "faafo" osteoporosis of lafaha axial meelaha ay ka durugsan, si marka hore waa in aad baari araxda for ogaanshaha hore. densitometry Free, nasiib dhif ah, tan iyo markii ay sahanka waxaa badanaa lagu qabtaa xarumaha caafimaadka gaarka loo leeyahay iyo u baahan tahay qalab ku haboon.
