Densitometry wheua me te osteoporosis - tetahi atu wāhi ki te kitea i roto i roto i mua e pā ana ki te mate

Osteoporosis - māuiuitanga, i roto i nei ngaro nga wheua konupūmā, reira hoko he pakarukaru. Ki te kahore he te take pāmamae iti rawa kia deform ratou whatiia ranei. Hape whakapono e puta te mate i roto i te iwi kei roto i te nui takarepa o te konupūmā nei tinana. E kore te mea pono tenei. whakawhanake osteoporosis noa ki te taikaha o ngā huānga wahi i roto i te kai. Ko te take mo te fragility wheua nui haere he iti absorption o wheua konupūmā ranei "Whakateatea".

Ko te etiology o osteoporosis

Ko te kiato o te wheua tei runga i te nui o hormones sex. I roto i te tangata, testosterone neke atu i nga wahine, ka pena o ratou wheua e nui nui, me te kaha. Ka rite ki te hua, kei te maha pāngia osteoporosis i wahine, rawa i roto i te menopause, no te mea i taua wa iti te taumata o hormones te tino.

I roto i te tahi atu take, kia tuhia te reira hypodynamia osteoporosis, kore o te huaora D, inu waina, kai paipa, aroaro o mate mau (mate huka, pāpaka thyroid, mate ate ma'i, me te tākihi).

Me pēhea te ki te tautuhi osteoporosis?

Ki te ta te tangata rohirohi me wheua mamae, huringa i roto i te tūranga me te kiwi e, mate makawe me te ino o te niho, me te piere auau, e tūtohu ana ki te hanga i densitometry. Ko te whakamātautau tere, me te tino mamae kore e taea ki te tautuhi me te ine i te mate o te wheua kiato, me te ihirangi kohuke ki te whakatū me te aromātai i te mōrea o piere tenei. Ko te tikanga āta tino tairongo mō te tātaritanga wawe o te osteoporosis tenei.

Ko te ngako o te densitometry te candling wheua e kitea X-hihi. I roto i tenei take, te whakamahi i te horopeta iti o ionizing radiation tukua i roto i te puka o rerenga pūngao e rua, e taea ai hoki te tirohanga nohopuku, me te tika.

Kei te tuhia te reira e wheua densitometry āhuatanga e te horopeta radiation, heke nei te ki te iti (he reira iti iho i te 1/10 o te horopeta i whiwhi tūroro i roto i te Radiography pouaka paerewa).

A, no te Ko te densitometry

Tuhinga hoki tenei rangahau ko te āhua e whai ake:

• menopause wawe ranei menopause, e puta i roto i nga wahine e whai ake nei paipa o paheketanga;
• te aroaro o te täkihi;
• mate ate ma'i;
• maimoatanga wā roa-ki glucocorticoids;
• syndrome malabsorption matūkai, e tika ana ki te konupūmā hē;
• Kei te whakahaere hoki te wheua densitometry i te aroaro o rheumatoid rumati, hyperparathyroidism me hyperadrenocorticism rite te pai kia rite ki i roto i te hypothyroidism me te mate huka.

Ki te mea i reira e piere ki whētuki iti, he reira ano hoki he tohu mo te rangahau. Kei te whakapono te reira e te takahi o te tapatahi o te wheua i roto i te osteoporosis whakaiti te tümanako ora o tūroro atu ara atu i te mate pukupuku, pera he tino nui te rapunga wā o te mate. Me kï reira e i roto i ētahi wā riro whakaatu puka o tenei māuiuitanga.

Wheua densitometry: Key

He ngā tikanga mō te kimi osteoporosis, engari ko te tino iti o ratou te whakamahi. Ko te kupu, e utu ngā whakarerekētanga o te MRI, ine tomography computed homai te nui horopeta o radiation, te ako o kuputohu matüora hāngai o te pākia wheua āhuatanga e ngā rerekētanga nui i roto i raraunga ture, a ka mana'o te manawanui hūhi ka nga wheua unuhanga. A, no te Ko te tātaritanga o osteoporosis, densitometry ko te tikanga tino rongonui.

Whakamahia e toru ngā rautaki matua e kua whakawhanakehia kua mō te rapunga o tenei mate:

• X-ray absorptiometry;
• Ultrasound densitometry;
• tomography computed piringa (he drawback nui - e kore e tukua ki te aromatawai i te huru o te wheua kōhiwi axial).

tango hoki kōwhiringa matau o te tikanga rangahau me te aromatawai tika o nga hua ki pūkete te peculiarities o faaiteraa haumanu. tangohia ano hoki ki te pūkete te paearu tātaritanga hāngai.

Ngaahi Tefito'i Mo'oni o aro mātai o ngā hua densitometry

Hei whakaahua i te raraunga rangahau whiwhi i muri i te wā "osteopenia" ranei te whakamahi i "osteoporosis". e kore kia whakaaro ratou rite te tātaritanga haumanu, engari anake i rite te tohu e taea tahi tetahi lesion kōhiwi ki whakaiti i kiato. Me kï reira e kore te wheua densitometry kawea atu hoki tātaritanga tika, me te ki te tāutu i ngā tūroro i mōrearea o whati.

Ki tenei taputapu pūmanawa (densitometer) whakataurite nga hua whiwhi me te pātengi raraunga i tīpakohia, ka ko tauanga te rerekētanga. Kei te whakaritea e te maha o te ine paerewa e huaina nei i te ingoa o T-whakamātautau (whakamahia hoki whakatairite ki te iwi taitamariki o te sex taua rite te manawanui) Z-whakamātautau ranei (mo te whakarite, e te rōpū o te iwi o tau tika, sex me te taimaha).

Ki te kore ko te T-whakamātautau neke atu i 2.5 SD, hāngai tenei ki osteopenia, ki te nga hua i raro i tenei ahua, korero tetahi o osteoporosis. E whakaaro ēnei uara "paepae." kia tenei kia whakaaro hoki te tikanga tika o ngā hua densitometry.

densitometry X-ray

Tū, me te awhina o X-ray irradiation taea tūhura te nuinga o nga wheua. Ko te tikanga puritia densitometry tuaiwi (tona tuarā lumbosacral) me hip, te wahi tino whakawhanake piere ki osteoporosis. whakatau hoki i te kiato o te wheua kiko huha me te kikowhiti densitometry noho te tinana katoa ranei. Tenei taea whakamātautau ki te whakatau i te ihirangi o kohuke i roto i ngā wāhi tīpakohia o te tinana, puta noa i te tinana ranei.

I roto i te mua mō te aro mātai i wheua papatipu me te ihirangi kohuke o te pūhui whakamahia tikanga kanoirite absorptiometry, te parau tumu o e ngā i roto i te whaki i te korakora kama, me te aromātai i te tohu o to ratou absorption. He ngoikoretanga nui o te rangahau taua ko te puaretanga radiation nui. Muri timata ki te whakamahi i rua-pūaho x-ray absorptiometry, i he tino tairongo, me te iti iho kino ki tūroro. Ki te rā, ka taea e tauturu i te reira te tautuhi% 2-3 anake o wheua mate, na kia whakamahia ai tenei rangahau mō te tātari wahine i roto i te menopause mo te kitenga wawe o te osteoporosis.

ultrasound densitometry

whakahaeretia ana tēnei momo o te rangahau te ki aromatawai wheua kaha. e tenei ki pūkete te kiato, microstructure me elasticity, me te te matotoru o te paparanga cortical. He painga nui o te rangahau taua - te ngaro o te radiation puaretanga. Whakaaro i te haumaru o tenei tikanga, e taea te faahiti i te reira, kahore tetahi here.

Me mea te reira e hāngai ana te densitometry taua kei i runga i te kaha o te ngaru ultrasonic tohaina haere te mata o te whenua, ranei marara i roto i te kiko wheua. I roto i tenei take, he mea ka taea ki te whakatau i te elasticity, mātotoru, me te pakeke o te wheua.

Me kï reira e te whakamahia te densitometry wheua ultrasonic anake mo te whakamātautau o te kōhiwi piringa. Nuinga o ngā wā, te korenga i tenei tikanga te rekereke me tibia, popoki, ranei phalanges. Te nuinga o nga mea whakatau i te tere o te whakatö ultrasonic attenuation ranei, e tohu i runga i te wheua kiato kore anake, engari ano hoki i runga i te wātea o te moroiti trabecular ranei.

mutunga

Ahakoa o pehea tukinotia osteoporosis te (i roto i te puka o te tohumate mate ranei), ka taea densitometry ki te whakatau i te mōrea o te whati. Kia mahara te reira e ko tino nui te pai rawa o te rohe rangahau, no te mea e kore ai nga densities o wheua mineralized ranei kia te taua mo te kōhiwi katoa.

Ki te hanga te pai rawa matau, e hiahia ana koe ki te mohio i te tauira e whai ake nei:

• taonga trabecular pāngia i roto i te syndrome menopausal hypogonadal tāne i pūtaiaki ranei;
• kitea kino maitai ki te wheua cortical te i taipāpā, hyperthyroid, osteoporosis huka;
• ki te te manawanui i roto i kōhungahunga taiohi ranei whakawhanake te mate e poka ki te tupu o te kōhiwi, kua pāngia nga wheua ki hē pūnahanaha. E haere tahi ratou i te kino ki paparanga wheua e rua.

kia mohio koe, e reira ko te au o "horahanga" osteoporosis o te kōhiwi axial ki ona wāhi piringa, kia kia tuatahi titiro koe i te pekehoe mō te tātaritanga wawe. densitometry Free, kāore onge, mai te nuinga o te rangahau whakahaere i roto i haumanu tūmataiti, me te titau taputapu e tika ana.
