Densitometry - waa maxay? densitometry Bone iyo dhabarta: muujinaya iyo qiimaha

cufnaanta lafaha ka tarjumayaa heerka fiirsashada xeryahooda ka imanba (tus, calcium). Si fudud u gelin, dhimaya this muujinaysaa xoogga canaasiirta.

Guudmarka

Iyada oo xaddiga lafaha qof kasta sanadihii la soo dhaafay hoos. Qaybaha noqon khafiif ah oo ay qaab-dhismeedka - ka badan oo iska furan. Tan waxa u sabab xaqiiqada ah in formation of unugyada lafuhu waa gaabis ka badan burburinta, catabolism ahaaday badan anabolism. Iyadoo da'da wanaajiyey leaching xeryahooda ka imanba ee canaasiirta. Tani, markeeda, yaraynaysaa xoogga lafaha, sii kordhaya suurtagalnimada of jab. Sidaas daraaddeed, osteopenia si tartiib tartiib ah u keenaysaa in osteoporosis. The denser asalka lafta, dheer ku qaadan doonto in ay u baabba '. In la xoojiyo layliga wax ku ool ah (tababar ku saabsan lagtiisa iyo socodka) iyo calcium supplements. The ugu casrisan ka mid ah qalabka sida "Actonel", "Fomasaks", "Miakaltsik". dumarka wakhtiga ma dhaleysnimada xilsaaray hormone (bedelka) therapy. Waxay kaa caawinaysaa in ay hoos u dhigi catabolism.

sababaha halista

qayb-qaato horumarinta ee osteoporosis, arrimo gaar ah.

• Age. Sida caadiga ah, in 30 sano waxaa lagu gaarayaa xoog badnaan iyo cufnaanta lafaha. Ka dib markii in uu jiro hoos u dhac tartiib ah.
• factor The jinsiga. nuglaato Greater horumarinta halligaad haweenka ka weyn 50 sano. Waxay afar jeer ka badan rag u nugul osteoporosis yihiin.
• qaab-dhismeedka lafta oo miisaanka jidhka. haween badan oo u badan yihiin nugul osteoporosis badan caatada ah oo khafiif ah. Xaaladdu waa mid la mid ah la jiray rag adynamic.
• Aqbalaada tiro ka mid ah daawooyinka. Tusaale ahaan, iyadoo la isticmaalayo daba dheeraaday ee wakiilada steroid (tus daroogada "prednisolone") waa maqalka saamayn xun ku lafo caafimaad qaba. Tani, ka bacdi, waxay kordhisaa suurtagalnimada of horumarinta osteoporosis.
• Joogitaanka laf jab ku anamnesis.
• xaalad Postoperative ka dib saarista ugxan.
• Taariikhda Qoyska. Mid ka mid ah arrimaha ugu weyn ee horumarinta cudurka lafaha waxaa loo arkaa inay iska dhaxlo. Xaaladdan haddii qaraabada (ayeeyooyinka, waalidiinta, ayeeyooyinka) calaamadaha joogo of osteoporosis (tusaale ahaan, jab of bawdada la yar dayrta a), halista ah ee ay horumarka waa mid qaali ah.
• qaadashada xad-dhaafka ah ee khamriga.
• Joogitaanka cudurada a degaaankaaga, Ulasocto Digo-dhaafka ah ee calcium in unugyada lafta (tus hypothyroidism).
• kicida Jirka.
• Markii hore, lafaha khafiif ah.
• Cuntada la content hooseeyo of vitamin D iyo calcium.
• dayska Hore.

Cabbiraad ee cufnaanta unugyada: Methods

Waxaa jira siyaabo kala duwan si ay u qabtaan daraasad. Mid ka mid ah habka loo jecel yahay waa densitometry. Waa maxay nooca cilmi? Habkani waa la fuliyay on qalab ah taariikhda gaar ah. Inta lagu guda jiro daraasadda bukaanka been on dhabarka miis iyadoo ka Faydatay Dhudhumadeeda dullaysnaan ama lugaha si toos ah. Next, ka fiirso wixii noqon kartaa densitometry, waa in kiis kasta oo lagu taliyey.

Dual-tamarta Baadhista X-ray

Tani waa mid ka mid ah siyaabaha lagu samayn karaa densitometry. Waa maxay - dual-tamarta x-ray? Habkani waxaa loo arkaa cabbirka ugu saxsan safaleeti. Xaaladdan oo kale, labada alwaaxdii saqafka kala duwan. Habkani waxaa loo sameeyaa densitometry oo ka mid ah lafdhabarta iyo miskaha. The denser nudaha, ayaa in ka badan ku adag tahay ku dhex mareen dogob X-ray. In summation ah, oo is barbar natiijada laba saamaynta nuugista takhasus waa inay awoodaan inay si sax ah loo dhigay hoos u cufnaanta ee nudaha. Iyada oo la adeegsanayo densitometry la qiyaasi karin, by khasaaro of 2% ka mid ah ay mass sanadkiiba. Socdaa densitometry (in uu yahay, kor ku xusan) muddo waqti yar. dose shucaaca The waa mid aad u yar in daraasadda.

densitometry lafta durugsan

Macluumaadka daraasaddan loo hagaajiyey hab is le'eg oo lagu in kor lagu sharaxay. Densitometry, qiimaha kuwaas oo la hoos ku hadli doonaa, oo u ogolaanaya inay sahamiyaan cufnaanta ee unugyada ee lugta iyo gacanta - in ay ciribta iyo curcurka. Si kastaba ha ahaatee, meelo kale si ay u fuliyaan cabbirka waa mid aad u adag. Gaar ahaan, waxay khuseysaa ku-dhabarta iyo sare ee darafkeeda hoose, halkaas oo jab inta badan ka dhacaan. Markii daraasadda kiiskan loo isticmaalo qiyaasta ah mid aad u yar ee shucaaca. densitometers durugsan yihiin telefoonada gacanta lagu qaadi karo. Waxay waxaa loo isticmaali karaa in xafiiska dhakhtarka caadiga ah ee. Waa in la ogaadaa in Macluumaadka habka cilmi ma aha mid aad u sarreeya. densitometry lafta durugsan ayaa lagu wadaa marka performing assays baaritaanka iyo sidoo kale in la socodka tayada daaweynta ee osteoporosis.

Habka laba-photon The

Daraasad kiiskan, waxaa loo isticmaalaa isotopes shucaaca. Habka waxa uu ka dhigayaa suurto gal ah in la qiyaaso cufnaanta ee unugyada ee dhabarta iyo misigta. Inta lagu guda jiro nidaamka, sidoo kale loo isticmaalaa qiyaasta shucaaca hooseeyo. Waa in la sheegay in densitometry laba-photon oo ka mid ah lafdhabarta iyo misigta u baahan yahay muddo dheer si aad u hesho natiijooyinka.

taranta CT

Tani waa hal nooc oo imaging, kuna waari dhexdeeda, waayo, qaab-dhismeedka lafta imaging iyo sawirka saxa ah ee gobolka unugyada shucaac X-ray loo isticmaalo qaab bulk. Si kastaba ha ahaatee, habkan in aan loo isticmaalin dhaqanka sidii ay marar badan, tus, densitometry lafta durugsan (sida kor ku xusan waxaa lagu tilmaamay). Tan waxa u sabab load shucaaca sare u shaqeeyo.

ultrasound densitometry

Qaabkan baaritaanka ku salaysan yahay cabbirka of xawaare la ruxruxo oo waxaa la qaybiyey in ka badan dusha dhar ah. Intaa waxaa dheer, broadband qiyaasey khasaarinayay aaga bartilmaameedka. Thanks to this nidaamka, takhasus ah oo qiimeyn kara ma aha oo kaliya cufnaanta, laakiin sidoo kale adadayga iyo barti ee nudaha. Informativeness daraasaddan uga liidataan kuwa kaas oo X-rays waxaa loo isticmaalaa.

maragga

Mari densitometry waxaa lagu talinayaa in qaybaha soo socda ee muwaadiniinta.

• Dadka haysta in ka badan 2 sababaha halista osteoporosis.
• Haweenka dayska. in la baaro waa in sida aan dabiici ahayn (ka dib saarista ugxan) iyo gobolka dabiiciga ah.
• Ragga ka badan 50 sano.
• Bukaanka osteoporosis samatabbixiyey radiographs.
• Dadka ka 40 sano kuwaas oo lahaa mid ka mid ah ama ka badan jab ah (haddii shil dhaco, dhaco, dhaawacyada shaqada ama sports).
• Bukaanka qaba hormoonada jidhka iyo heley rheumatic.
• Bukaanka qaba qalooca, saxanno herniated, dhabar xanuunka hooseeyo ama dhaawac laf-dhabarta.
• Kuwa qaata daaweynta osteoporosis (si loo ogaado tayada).
• Haweenka, waqti dheer in la isticmaalo uurka hormoonnada ah.
• Dadka qaba koror yar (ilaa hal mitir iyo badh), ma ay sabab u tahay hiddo.
• Dadka mass index oo gaadho 18.5 unugyada.

sababo

Tan iyo hirgelinta nidaamka bukaan-socodka la kulmin gaadhista X-ray laguma talinayo densitometry (xitaa in yar ka qaataan) dumarka uurka leh. Tan waxa u sabab jaaniska sare ee saameynta xun ee shucaaca on uurjiifka. Ka mid ah sababaha kale ee waxbarasho ee la ahaan uu laga yaabaa, waa in la ogaadaa,

• joogitaanka of implants macdan ah loo isticmaalo in qalliin dib u,
• arthritis-dhabarta,
• dhaawacyo soo dhaafay, jab.

Densitometry laguma talinayo muddo 10 maalmood ah ka dib markii baaritaan X-ray oo isticmaalaya duwan barium ah.

tababarka

Densitometry, qiimaha oo kala duwan oo u dhexeeya 2,000 rubles - hab aan xanuun lahayn. Ka hor inta aan hirgelintiisa muhiim ma aha in si kasta oo si gaar ah loo diyaariyey. Sida caadiga ah, waayo cabbirka of cufnaanta unugyada ku filan habka keli ah.

Koorsada waxbarasho

Ka hor inta performing nidaamka, bukaanka waxaa la weydiiyay in meesha laga saaro dhammaan waxyaabaha dahabka waxyaabaha biraha. Daraasadda ma keeno raaxo aadanaha, waa non-invasive. Densitometry ma sababi waxyeello ka soo gaartey. Its duration - 5-20 daqiiqo. Muddada ay ku xiran tahay xaddiga cilmi. Inta lagu guda jiro nidaamka iskaanka waxaa la sameeyaa iyadoo X-rays meelaha lafaha. Cabirka heerka nuugista shucaaca wuxuu diyaariyaa shidma ah. Iyada oo ku saleysan macluumaadkan, jadwalka lagu dhisay. qaybta cabiraada aagga qiyaas iyo fiirsashada xeryahooda macdanta. On ku salaysan tilmaamayaasha, kuwaas waxaa loo xisaabiyaa cufnaanta unugyada.

natiijada

qiyamka ayaa helay qiyaaso dhamaadka, ka muujiyay tilmaamayaasha T iyo Z. The T-score ugu horeysay barbardhigay cufnaanta ee unugyada laf ka mid ah bukaanka si loo xakameeyo soo koobin ee dadka caafimaadka qaba 30 sano jir ah. Z Miisaanka kuu ogolaanaya in aad is barbar dhig la soo koobin celcelis ahaan dadka sida ay tartanka, jinsiga iyo da'da. Sida caadiga ah, ee suga waa in aan ka yarayn 1 weecasho caadiga ah. cufnaanta ee kala duwan ee ka -1 in -2,5 T-score waxaa loo arkaa osteopenia, i.e. gobolka ka hor muuqaalka kore ee osteoporosis halis dhexdhexaad ah oo jab ah. Marka qabashada cudur-qaaday unugyada account nonuniformity cufnaanta ee goobaha kala duwan.

Gebogebadii

Maanta, cudurka of osteoporosis, habka cilmi-baarista ugu caansan ahaa si hufan densitometry. Halkee nidaamka samayn? cilmi Tan waxaa loo sameeyaa in ku dhow magaalo kasta oo dalka ah, rugaha badan oo dhuuban-profile. Haddii loo baahdo ay ku soo celiyaan nidaamka kaa caawin gacanta jimicsi badan gobolka-shiid macdanta. Waxa ay inta jeer ee la doorto qof kasta oo si gaar ah. Tani waxay qaadataa galay account muuqaalada xirfadda, da'da, iyo taariikhdaada caafimaad.
