Densitometry - chii? Bone densitometry nomuzongoza: zvairatidza uye mitengo

Bone arambe achirema inoratidza padanho Kuwanda inorganic yeimwe (semuenzaniso, karusiyamu). Zvichitaurwa zviri nyore, parameter ichi zvinoratidza simba okunze.

tsananguro

With uwandu pfupa rimwe munhu kwemakore kunoderedza. Zvinhu zvinova wakawondereiko kudai mazuva ose uye avo marongerwo - zvikuru porous. Izvi imhaka yokuti paumbwe mapfupa rinenge riri nomumugwagwa kwaitora nguva pane kuparadzwa, catabolism akavamba pamusoro anabolism. With zera kunowedzera leaching pakati inorganic yeimwe ose okunze. Izviwo, zvinoderedza simba mapfupa, kuwedzera mukana wokuti mitswe. Saka, osteopenia zvishoma nezvishoma kunounza osteoporosis. The denser chepakutanga pfupa, kwenguva refu zvichaita kuti kuparadzwa kwaro. Kuti usimbise chinobudirira muviri (kurovedza pamusoro simulators uye tichifamba) uye calcium yakawanda zvokuwedzera. Chinonyanya ano vanosanganisira munowanika "Actonel", "Fomasaks", "Miakaltsik". Vakadzi kuenda kumwedzi basa kemikari (yokutsiva) kurapa. Zvinobatsira kunetesa catabolism.

zvinokonzera njodzi

kubatsira kutanga osteoporosis, zvimwe zvinhu.

• Age. Kazhinji, makore 30 kunokwanisika simba kunonyanyisa uye mapfupa arambe achirema. Pashure paizvozvo pane zvishoma nezvishoma kuderera.
• The chechikadzi chikonzero. Greater susceptibility kuti kukura kuparadza vakadzi makore 50. Ndivo runa kupfuura vanhu asingatani osteoporosis.
• Bone mamiriro uye muviri uremu. Vakadzi Large ndivo tichikurumidza osteoporosis pokuvimba uye dzakaonda. Mamiriro acho ezvinhu akafanana ne adynamic varume.
• Kubvuma zvinoverengeka mishonga. Somuenzaniso, nekushandisa kwenguva yakareba steroid yomuchipatara (semuenzaniso zvinodhaka "prednisolone") iri yakakura kunambwa pfupa utano. Izviwo, anowedzera mukana wokuti dzichiri osteoporosis.
• Kuvapo mapfupa mitswe mu anamnesis.
• Postoperative ezvinhu pashure nokubviswa ovaries.
• nhoroondo yemhuri. Chimwe chezvinhu zvinokosha kukura mapfupa chirwere anoonekwa kuti nhaka. Kana kana hama (navanasekuru, vabereki, vanasekuru) aripo zviratidzo osteoporosis (semuenzaniso, pakakuvara ari femur pamwe zvishoma kuwa), mukana wayo pakukura zvakakwirira zvikuru.
• Kunwisa yaunodya doro.
• Kuvapo munhu somatic zvokurwara pamwe nokunyanyisa excretion calcium mu mapfupa rinenge (semuenzaniso hypothyroidism).
• Nokusarovedza muviri.
• Pakutanga, mapfupa mutete.
• Food pamwe yakaderera zviri vhitamini D uye calcium yakawanda.
• Early kubereka.

Kuyerwa zvinyama arambe achirema: Nzira

Pane dzakasiyana kuti azodzidza. Imwe nzira yakakurumbira ndiyo densitometry. Imhandoi tsvakurudzo? nzira iyi kuitwa musi michina chaiyo. Munguva yokudzidza murwere riri shure yake tafura chakaunyana shins pasi kana ngaatarire makumbo. Next, funga zvingaguma densitometry, zviri kuzvidzosera inokurudzirwa.

Dual-simba X-ray Diagnostics

Iyi ndiyo imwe nzira iyo kuti anogona akaita densitometry. Chii - Dual-simba X-ray? Nzira iyi anonzi akarurama kupfuura kuyerwa pamwe tishu. Panyaya iyi, vaviri matanda zvakasiyana. Nzira iri rinoitwa densitometry pamusoro nomuzongoza uye muhudyu. The denser ari zvinyama, zvikuru zvakaoma nepakati X-ray danda. Munguva summation, uye kuenzanisa migumisiro maviri Absorção de Água migumisiro nyanzvi anokwanisa zvakarurama akaisa arambe achirema zvinoderedza tishu. Pachishandiswa densitometry kuyerwa nokurasikirwa 2% nevazhinji kwayo pagore. Rinogara densitometry (ndiko kuti, pamusoro) duku nguva nguva. The nemwaranzi dose zvikuru pasi ari kudzidza.

Peripheral pfupa densitometry

Mashoko ari kudzidza rakagadzirirwa nenzira zvineringanidzo nenzira kuti zvataurwa pamusoro apa. Densitometry, mutengo izvo dzichakurukurwa pazasi, anobvumira kuongorora arambe achirema iri rinenge riri gumbo uye ruoko - chitsitsinho uye chiningoningo. Zvisinei, mune dzimwe nzvimbo kuti tiite nokuyerwa zvakaoma zvikuru. Zvikurukuru, ichi chinoshanda musana uye musoro rezasi kumugumo, apo mitswe kuitika inonyanyoshandiswa. Kana iri nyaya yokudzidza akashandisa pasi kwazvo chipimo chemushonga nemwaranzi. Peripheral densitometers vari inotakurika dzeserura. Vanogona kushandiswa muhofisi zvake chiremba. Zvinofanira kucherechedzwa kuti mashoko zviri ichi tsvakurudzo nzira hakusi yakakwirira chaizvo. Peripheral pfupa densitometry yakaiswa kana kuita kuongorora assays uyewo vachiongorora kuti kunyatsoshanda pamusoro nokurapa osteoporosis.

Vaviri-photon nzira

Muchiitiko ichi kudzidza, anoshandiswa radioactive isotopes. Nzira zvinoita kuti kufungidzira arambe achirema iri rinenge riri nomuzongoza uye muhudyu. Munguva nzira, akashandisawo yakaderera nemwaranzi chipimo chemushonga. Zvinofanira akati kuti vaviri-photon densitometry pamusoro musana uye muhudyu kunoda kwenguva refu kuti zvabuda.

quantitative CT

Ichi chimwe mhando kuri, sezvamakaropafadzwa nokuti kuri pfupa zvivako uye mufananidzo zvinyama ezvinhu X-ray nemwaranzi kwechokwadi rinoshandiswa zvakawanda chimiro. Zvisinei, nzira iyi haina kushandiswa tsika kakawanda, semuenzaniso, peripheral mapfupa densitometry (sezvazvakanyorwa anorondedzerwa pamusoro). Izvi imhaka yakakwirira nemwaranzi mutoro pamusoro muviri.

Ultrasound densitometry

nzira iyi kuongorora hwakavakirwa nokuyerwa chinozunguzirwa velocity nako riri kuparadzirwa pamusoro jira pemvura. Mukuwedzera, nokukosha Broadband vachipararira ari chipfuro wongoramba. Nemhaka nzira iyi, nyanzvi anogona kuongorora kwete chete arambe achirema, asiwo kuomarara uye elasticity yacho tishu. Informativeness yokudzidza ichi zviri muduku avo umo maekisirei anoshandiswa.

umboo

Kumbotambudzika densitometry inokurudzirwa mu zvinotevera Mapato vemunyika.

• Persons kuva anopfuura 2 zvinokonzera ngozi osteoporosis.
• Vakadzi vari kubereka. Zvinofanira kuongororwa sei chakagadzirwa (pashure Kubviswa ovaries) uye zvakasikwa mamiriro.
• Men makore 50.
• Varwere akanunura osteoporosis pa radiographs.
• Persons makore 40 vakambova mumwe kana kupfuura mitswe (pakuparwa tsaona, akawa, kukuvara kubasa kana mitambo).
• Varwere kwemakemikari anobudiswa uye rheumatic pathologies.
• Varwere scoliosis, herniated discs, pasi musana kurwadziwa kana musana kukuvara.
• Vaya Mabatirwo osteoporosis (kuziva kunyatsoshanda).
• Women, refu nguva kushandisa hormone pamuviri.
• Vanhu vane zvishoma kuwedzera (kusvika rimwe nehafu metres), kwete nemhaka yedzinza.
• Persons vakawanda indekisi iyo rinosvika 18.5 dzakabatana.

Contraindications

Sezvo Implementation pamusoro nzira murwere pachena kuti X-ray dzokupisa haina varumbidzwa densitometry (kunyange mishonga duku) kuvakadzi vane mimba. Izvi imhaka yakakwirira ndingangokuvara kukanganiswa mugumisiro nemwaranzi pamusoro azvarwa. Pakati pezvimwe zvikonzero kudzidza anogona contraindicated, zvinofanira kucherechedzwa:

• kuvapo esimbi anodyara zvaishandiswa reconstructive kuvhiyiwa;
• yemajoini of muzongoza;
• zvichangobva kukuvara, mitswe.

Densitometry haina varumbidzwa kwemazuva 10 mushure X-ray Kuongorora vachishandisa barium musiyano.

kudzidza

Densitometry, mutengo izvo zvinosiyana pakati 2,000 rubles - a nyarara muitiro. Asati yayo Implementation hakusi zvakakodzera chero nzira zvikuru kugadzirira. Kazhinji, nokuti nokuyerwa zvinyama arambe achirema kwakakwanira imwe nzira.

The kosi yokudzidza

Asati kuita muitiro, murwere akakumbirwa kubvisa zvose zvishongo zvinhu pamwe zvinhu zvesimbi. Kudzidza haakonzeri munhu kusanzwa, riri non-invasive. Densitometry haakonzeri nemigumisiro. nguva yaro - maminitsi 5-20. Nguva kunobva uwandu kutsvakurudza. Panguva kushanda pakuvheneka nzira rinoitwa pamwe maekisirei skeletal nzvimbo. Kuyera padanho nemwaranzi Absorção de Água unocherekedza munhu Switch. Mashoko aya, purogiramu inovakwa. Nokuyerwa chikamu fungidziro nzvimbo uye wevasungwa pakati chicherwa yeimwe. Pahwaro zviratidzo izvi rinowanikwa tishu arambe achirema.

mugumisiro

Tsika yaunganidzwa kuyera mugumo, akaratidza zviratidzo T uye Z. rokutanga T-mamakisi rinofananidza arambe achirema pakati pfupa rinenge murwere kudzora parameters vanhu utano makore 30 makore. Z Scale kunoita kuti kuenzanisa avhareji parameters vari vagari maererano nedzinza, vakadzi uye zera. Kazhinji, kusimba Hachifaniri kuvatumwa 1 mureza kutsauka. The arambe achirema iri zvinobva -1 kusvika -2,5 T-mamakisi anoonekwa sezvo osteopenia, i.e. hurumende isati nechitarisiko osteoporosis pa mwero mukana mitswe. Pakuitisa chirwere kufungwa rinenge arambe achirema nonuniformity panguva nzvimbo dzakasiyana.

In mhedziso

Nhasi, nechirwere pamusoro osteoporosis, kupfuura mukurumbira tsvakurudzo nzira chaiwo densitometry. Apo nzira kuitei? tsvakurudzo iyi akaita mune zvinenge guta ose munyika, multilateral uye yakamanikana-Profile yekuongororwa. Kana zvakakodzera kudzokorora pachishandiswa zvinobatsira muviri kudzora mamiriro chicherwa muviri. maitikiro yavo anosarudzwa kuti mumwe murwere nomumwe. Izvi inorangarira zvaidiwa basa, zera, uye nhoroondo zvokurapa.
