Densitometry - ntoni na? Bone densitometry kunye umqolo: zikhombisa kunye namaxabiso

Bone ezinoxinano ibonisa inqanaba lwee- iikhompawundi ezingaphiliyo (umz, calcium). Ngamafutshane, le parameter ibonisa amandla izinto.

Overview

Xa isixa-mali ithambo lomntu ngamnye kule minyaka kunciphisa. Elements aselula nokwakheka kwawo - nakwamanye amazwe. Oku kungenxa yokuba ukuba ukuyilwa esiqwini ithambo elicothayo kokutshatyalaliswa, catabolism ufakwa anabolism. Nge ubudala zisenze iziniki-iikhompawundi zondle ngayo izinto. Oku, kunciphisa ngamandla amathambo, ukwandisa amathuba waphuka. Ngoko ke, osteopenia ngcembe kukhokelela kwamathambo. I luthe original ithambo, ixesha elide oko aya kutshabalala yayo. Ukomeleza lo msebenzi olusebenzayo (uqeqesho simulators kunye nihamba) kunye nezongezo calcium. Eyona mihla zibandakanya izixhobo ezifana "Actonel", "Fomasaks", "Miakaltsik". abafazi ngxaki hormone (replacement) unyango isabelo. Inceda ukwehlisa catabolism.

ubungozi

igalelo kuphuhliso kwamathambo, izinto ezithile.

• Age. Ngokuqhelekileyo, iminyaka engama-30 kufikelelwe namandla esiphezulu kunye kwamathambo. Emva koko kukho ukuhla ngokuthe ngcembe.
• Le factor isini. susceptibility Greater kuphuhliso yentshabalalo yabasetyhini abangaphezulu kweminyaka engama-50. Yokuba kane ngaphezu amadoda othambekele kwamathambo.
• isakhiwo Bone kunye nokutha emzimbeni. abafazi ezinkulu usesichengeni kwamathambo sayame elibhityileyo. Le meko ifana namadoda adynamic.
• Ukwamkelwa kwenani amayeza. Umzekelo, kunye nokusetyenziswa elide arhente steroid (umz iziyobisi "prednisolone") ukuba ziyanyuswa nefuthe elibi empilweni ithambo. Oku, lwandisa amathuba yokuvela kwamathambo.
• Ubukho kwamathambo in anamnesis.
• imeko Postoperative emva kususwa zamaqanda.
• imbali yosapho. Omnye weyona miba ibalulekileyo kuphuhliso bamathambo kuthathwa ukuba ilifa. Kwimeko ukuba izalamane (oomawokhulu, abazali, oomawokhulu) imiqondiso akhoyo kwamathambo (umzekelo, ukwaphuka yifemur kunye ukuwa kancinane), umngcipheko lophuhliso yalo kakhulu eliphezulu.
• inani Ukusela utywala.
• Ubukho a ngezifo somatic ekhatshwa zinomgutyulo ngokugqithisileyo icalcium esiqwini amathambo (umz hypothyroidism).
• lutho Physical.
• Ekuqaleni, amathambo obhityileyo.
• Ukutya enesiqulatho ophantsi ivithamin D kunye calcium.
• kwabadala Early.

Ukulinganiswa esiqwini mninzi: Indlela

Kukho iindlela ezahlukeneyo ukuqhuba isifundo. Enye indlela popular densitometry. Luhlobo luni uphando? Le nkqubo yenziwa ngomhla izixhobo umhla okhethekileyo. Ngexesha isifundo isigulane ubuxoki ngomqolo itafile kunye shins aqondele phantsi okanye imilenze tye. Okulandelayo, cinga yintoni kuba densitometry, oko kwenziwe nayiphi na imeko ekucetyiswa.

Dual-amandla uxilongo X-ray

Le yenye yeendlela ukuthi engenziwa densitometry. Yintoni na - ezimbini-eneji x-reyi? Le ndlela ithathwa umlinganiselo kakhulu oluchanileyo kwithishyu. Kulo mzekelo, imiqadi ezimbini ezahlukeneyo. Le ndlela lwenziwa densitometry yomqolo kunye esinqeni. I luthe inyama, anzima udlule beam X-ray. Xa summation, baze bathelekise iziphumo yeziphumo ezimbini ukufakwa zeengcali uyakwazi ukubeka ngokucokisekileyo ngakumbi indlela zokunciphisa mninzi in kwithishyu. Ngokusebenzisa densitometry lingaba nokulinganiswa yi ilahleko-2% ubunzima balo nyaka ngamnye. Lihlala Kuze densitometry (oko kukuthi, ngasentla) ixesha ixesha elincinane. Ithamo radiation iphantsi kakhulu kolu phando.

densitometry bone neuropathy

Ulwazi kwi sifundo yalungiselelwa ngendlela emeleneyo loo ezichazwe ngasentla. Densitometry, ixabiso apho kuya kuxoxwa ngezantsi, ivumela ukuhlola lexinene esikule komlenze ngesandla - isithende kunye esihlahleni. Noko ke, kwezinye iindawo ukuze baphumeze isikali nzima kakhulu. Ngokukodwa, oku kusebenza kwalapho kunye phezulu ezisekupheleni asezantsi, apho yamophula zenzeka qho. Xa lo mzekelo kuxoxwa wasebenzisa idosi esezantsi gqitha yabafundi be radiation. densitometers neuropathy ezi phones eziphathwayo. Baya ungasetyenziswa ofisi an ugqirha oqhelekileyo ngayo. Kufuneka kuqatshelwe ukuba okukule ingcaciso yale ndlela phando ayikho phezulu kakhulu. densitometry bone neuropathy umiselwe xa enza zePCR zokuhlola kwakunye esweni ukusebenza yonyango kwamathambo.

Indlela photon-amabini

Kulo mzekelo sifundo, kusetyenziswa izinto ezineeathom ezilinganayo eqhumayo. Le ndlela yenza kube lula ukuqikelela lexinene esikule lomqolo kunye hip. Ngexesha inkqubo, naye wasebenzisa idosi radiation eliphantsi. Kufuneka ke ukuba densitometry photon-ezimbini yomqolo kunye kasikrobana kufuna ixesha elide ukufumana iziphumo.

belinani CT

Le yenye uhlobo umfanekiso, apho ngokuba umfanekiso izakhiwo ithambo kunye umfanekiso ngokwenene inwebu imo radiation X-ray isetyenziswa ngohlobo isambuku. Nangona kunjalo, le ndlela alisetyenziswa practice ngamaxesha onke, umz, densitometry ithambo neuropathy (njengoko kuchaziwe apha ngasentla). Oku kungenxa yokuba umthwalo radiation phezulu eziphilayo.

ultrasound densitometry

Le ndlela phando isekelwe yomlinganiselo lwamaza Velocity ozibandakanya isasazwa phezu komhlaba laphu. Ukongeza, i-broadband kuqikelelwa uchithachitha kummandla target. Ngenxa yale nkqubo, ingcaphephe kubhekwe kuphela lexinene, kodwa ngumkhinkqi kunye luthambe le kwithishyu. Informativeness yolu phando ungaphantsi kakhulu kwabo apho-X-reyi zisetyenziswa.

ubungqina

Baye densitometry kuyacetyiswa kwezi ndidi zilandelayo abemi.

• Abantu ke izinto ezingaphezulu kwama-2 lomngcipheko kwamathambo.
• Women in ukuya exesheni. Ukuba kuvavanywa njani ngumntu (emva nokususwa amaqanda) nakwimo yendalo.
• Amadoda angaphezu kweminyaka engama-50.
• Abaguli kunikelwa kwamathambo kwi radiographs.
• Abantu ukusuka kwiminyaka engama-40 abaye baba Ukophuka enye okanye ngaphezulu (kwimeko yengozi, uwe, ukwenzakala emsebenzini okanye kwezemidlalo).
• Izigulane yonyango kunye ezimbi rheumatism.
• Izigulane zokufota, idiski herniated, libya iqolo okanye ukwenzakala umnqonqo.
• Abo bafumana unyango kwamathambo (ukumisela ukusebenza).
• Abafazi, ixesha elide ukusebenzisa zokucwangcisa hormone.
• Abantu abane ukunyuka okungephi (ukuya kwenye kunye iimitha nesiqingatha), kungekhona ngenxa yofuzo.
• Abantu isalathisi mass leyo efikelela iiyunithi 18.5.

Izimo

Ukususela Ukuphunyezwa kwale nkqubo isigulane ubethwa sesichengeni X-ray ayikhuthazwa densitometry (nokuba ngeedosi ezincinane) kwabasetyhini abakhulelweyo. Oku kungenxa amathuba eliphezulu isiphumo esibi lwe radiation ekukhuleni kosana olungekazalwa. Phakathi kwezinye izizathu ukuba isifundo contraindicated, kufanele kuphawulwe:

• ubukho nokufakelwa ebuntsimbi ezisetyenziswa Ukuhlinza;
• kwamalunga yomqolo;
• umenzakalo yakutshanje, waphuka.

Densitometry akukho Kunconywa iintsuku ezili-10 emva kokuba iimviwo X-ray usebenzisa umahluko barium.

uqeqesho

Densitometry, ixabiso apho uyahluka 2,000 engange - inkqubo elula. Phambi kokuziphumeza nokwenza kwayo akuyomfuneko nangayiphi na indlela uzilungiselele ngokukhethekileyo. Ngokuqhelekileyo, kumlinganiselo esiqwini konga ezaneleyo inkqubo enye.

Ikhosi yokufunda

Phambi kokwenza inkqubo, isigulane wacela ukuba ususe zonke izinto izacholo iziqalelo yesinyithi. Uphononongo akubangi ukuqaleka yabantu, kuba non-invasive test. Densitometry akuthethi ukuba iziphumo ezibi. ubude bayo - imizuzu 5-20. Ubude ixhomekeke kubungakanani zophando. Ngexesha ukuskena lenquba yenzelwa ne-X-reyi kwiindawo skeletal. Ukulinganisa umgangatho ukufakwa radiation oqondela a woluvo. Ngokusekelwe kule nkcazelo, ishedyuli yakhiwa. Le yokulinganisa Inxalenye kwindawo projektha kunye lwee- iikhompawundi kwezimbiwa. Ngokusekelwe kwezi zalathisi libalwa ijwabu mninzi.

ngenxa

Amaxabiso ezifunyenwe ngokulinganisa ekupheleni, wavakalisa izalathisi T kunye Z. lokuqala T-score ithelekisa lexinene inwebu ithambo isigulane ukulawula i parameters yabantu abanempilo engama-30 ubudala. Z Isikali ikuvumela ukuba ukuthelekisa ne-avareji parameters kubemi ngokobuhlanga, isini kunye nobudala. Ngokwesiqhelo, le ukuqina kufuneka ungabi ngaphantsi kwe-1 ecaleni. Ukuxinana kuluhlu ukususela -1 ukuya -2,5 T-score kuthathwa osteopenia, ngamanye urhulumente phambi imbonakalo kwamathambo emngciphekweni ngokulinganisela waphuka. Xa uqhuba diagnostic kuthathelwa ingqalelo inyama mninzi nonuniformity kwiindawo ezahlukeneyo.

Ekuphetheni

Namhlanje, uxilongo kwamathambo, indlela zophando edume yile densitometry. Phi le nkqubo? Olu phando lwenziwa phantse kuzo zonke izixeko zeli lizwe, iikliniki amazwe kunye elimxinwa-iprofayili. Ukuba kuyimfuneko ukuphinda neenkqubo ukunceda alawule phezu ngobume wezimbiwa ukutya. esasidla yazo sikhethelwe ukuba isigulane ngamnye. Oku kuthatha zibe iimpawu ingqalelo komsebenzi, ubudala, yaye imbali yezonyango.
