He aha te MRI o te tahi turi rite mahi e ka MRI o te turi?

Ko te tahi turi ko te whakaraerae tino i roto i te pūnaha musculoskeletal tangata. Ko Ko te aha te tātaritanga o wharanga turi - ko te raruraru tūturu o te traumatology. whakaaro te turi pai atahanga tahi technique te atahanga te kōwarotanga autō (MRI). Ki reira ka taea e koe te tātari i te whānuitanga o injuries, tīmata ki tuhonohono haea , me te mutu piere. He aha te MRI o te turi? Kia pehea te mahi i te scans? I roto i enei take ki te kia kōmaka i roto.

Anatomy o te tahi turi

Ko tenei pūhui te nui rawa i roto i te tinana tangata. Bone turi turanga - ko te pūkaka me tibia me te popoki. Kapiti e kore e pā ana ki te tahi. Ko te mata o te wheua hanga pūhui, hipoki ki te wheua ngohe. Ngā mihi ki reira heke te kaha waku me whakarite noho pai o te kaupapa te.

I te mutunga distal o te pūkaka e rua condyle - lateral (raro) me medial (nui). E ratou he āhua tawhio. Condyles reira me i te pito rarahi o te tibia. He āhua flat ratou. I waenganui i te kahui papa ko nga menisci (waho, me te roto) - wheua ngohe falcate. ū ai ratou te turi, whakamana te tūranga o te ru absorber i roto i te reira.

I tawhiti te tahi turi e rave rahi taura whakarite ona pūmautanga:

• takakaha (medial) kaiwhakakapi;
• kapiti (lateral) kaiwhakakapi;
• ACL;
• cruciate posterior.

Ko te hanganga ano ngā he iohere turi. I mua i whakaaro koutou MRI o te tahi turi, i whakaatu ko reira ia tapao e i roto i te nuinga o te wā pakaru te iohere o nga uaua whā. Tona break e tika ana ki te hukihuki ohorere o te uaua. I te tahi taime e pāngia whara me te mātotoru iohere whanui iliotibialnogo wahi. Tenei hanganga Ko te stabilization hihiri lateral kaha o te tahi turi.

Tuhinga hoki MRI

Tūkino ki ngā hanganga o te turi puta tino pinepine. Ko te tohunga e rapu matua iwi taitamariki ārahi i te āhua noho kaha me te mahi. I mua ki te whakarato o te āwhina ki ngā tākuta kawea i roto i te MRI. Ko te tikanga tika, me te pono mo te tātaritanga o ngā wharanga tenei.

I roto i MRI o te turi, i reira e etahi tohu. Ko ētahi o ēnei:

• kino taea ki te taunaha me te cruciate tuhonohono;
• ofatiraa i te tapatahi o te tīhaetia tendons ranei;
• whakapae whati;
• mamae i roto i te turi;
• mōhiohio whakatakotoranga whiwhi i roto i Radiography.

Contraindications ki te ako

"He aha e MRI o te tahi turi me te waewae?" - he pātai ki e kia rapua ai te whakahoki, e kore te iwi katoa, no te mea tenei tikanga o te tātaritanga i reira he contraindications:

• te aroaro o te pacemaker (pacemaker), te mahi o nei e taea te whakakahore e tika ana ki te ako;
• superimposed i runga i nga topenga oko toto whakarewa e taea te neke tika ki mana o te papa autō;
• raruraru o te manawanui;
• apiapi;
• implants ferromagnetic, no te mea o e tahuri i kore whakapakoko tika tino hē nga hua o te rangahau;
• hapūtanga ki runga ki te 12 wiki.

Mai i tenei rārangi kia tatou whakahua apiapi. Ehara i te mea he contraindication tūturu. A, no te kahore he hohonu te faaiteraa o te wehi o te manawanui o kati me herea whakamahi wāhi whakarokiroki rehunga ranei.

rangahau te whakahaere

Nahea te MRI o te turi - he kaupapa wera mo te iwi, te hunga kua whakaritea e tenei tukanga. Na i mua i te raveraa i MRI tūroro whakahere ki te hoatu i runga i kakahu motuhake. Ka taea e koe te noho i roto i ratou mea, ki te whai ratou kahore pātene whakarewa, zippers. I mua ka Me hoki te ako ki te tango i katoa whakapaipai, mohiti, mataaratanga, tango i te whitiki o te mau taviri, waea pūkoro.

whakamana matawai e ki te maungārongo manawanui. E whakanohoia ana te waewae ki te mea. I roto i te ako, ko te huha i roto i te pōkai auau irirangi. he whakarara ki reira alangá hauora. Raro i te huha rangahaua kopakia ana te he takai iti. E mea titauhia mo te mātakitaki pai o te nape.

Ki te reira te mea he māharahara mo te aroaro o te puku, ka whakamana te rerekē MRI. I mua i whakamatautau i te rua o te manawanui whakahaerea nei he taonga motuhake. He mea tika ki te whakarite i whakakitea te MRI turi te puku.

tinana MRI o te tahi turi

He nui hoki te tātaritanga tika ki te mohio e ka whakaatu MRI he noa te turi. Tenei ko te whakamārama o te wāhanga matua o te turi:

1. I roto i te nape pona ACL noa i runga i T2-T1 me VI-VI rite te hanganga titiro mangu ki te Hürai, kaha tohu iti. nape Posterior i roto i te whakapakoko i whiwhi e MRI, e feruri te reira i roto i te puka o te pai-tautuhi taura pango ōrite.
2. Tibial me fibular hei utu nape tikanga whakarato i T2-T1 me VI-VI ōrite tohu kaha iti.
3. menisci Normal i runga i T2-T1 me VI-VI Ua feruri hanganga rite homogeneously hypointense (ki runga, ki pango) ki paihere karere pokapū me oko toto. Ko te takiwa o nga menisci mārama, he maheni te mata.
4. Tendons tikanga rawa iti tohu tūturu. kia ara e kore e hoatu e ratou a reira ki whakapakoko o iri i T1 me T2.
5. āhuatanga ngohe Articular e te kaha tohu iti i runga i T2-VI me te kaha tohu toharite i runga i T1-VI.

kino nape

Ko te wharanga tino noa ki te nape ko te ACL. E whakaatu ana MRI e pakaru te tahi turi ko tenei hanganga? I whati nui haere tohu kaha i roto i te paihere. He pea he te whakamutu ngaro ranei o te tohu noa. A, no te ļa wharanga hou uaua e hua MRI te aroaro ngaro ranei o te whati, no te mea ka piki wharanga nape i roto i te rahi (i reira te huamo).

kia whara hei utu nape te whati oti, he roimata te kanohi, me te āputa intraligamentous. Ki te kitea e koe i te nape tibial hei utu pakaru, na ka kitea te reira thickening. whakanui i Manifest wahi te tohu. Ko tenei te mea whakaatu te MRI turi i roto i te ra tuatahi. I muri, ngaro tika ki absorption o wai te taikaha i roto i te whara kikokiko e karapoti ana i enei wahi.

pāngia Wehenga nape hei utu fibular, te tikanga rawa onge. E ngā taua whara ki nui piere comminuted o te mate condyle wheua tibial karapoti te kopa ngohengohe.

kino ki nga menisci

Hoki wharanga o te turi e whakaaro hanganga tahi ki te hei i te whakapakoko tino kōrero whiwhi i roto i nga rererangi sagittal me coronal. Hei aromatawai i te aha e MRI o te turi, me te tātaritanga, tākuta whakarongo ki te āhuatanga e whai ake nei:

• rahi tīhaetia;
• ratou whirihoranga, āhua o te tohu;
• matotoru me te hōhonu o te tohu whakarerekētia;
• localization o huringa i roto i te tīhaetia.

Te tautuhi i te maha o ngā nekehanga kino tīhaetia :

1. tohu Tuatahi - parau- ore- e hōloa pokapū. I roto i MRI kitea huringa e i roto i te tīhaetia. whakakitea whakarei ratou tohu kaha.
2. tohu Tuarua - he e hōloa pokapū noa. Roto te tīhaetia hurihia ei te rohe whānui o nui haere kaha tohu.
3. Ko te tohu tuatoru - tīhaetia haea. Roto te tīhaetia whakakitea nui ake kaha tohu. pakaru te aratau o wāhi kōtuitui-articular. I te tahi taime te tūnga o nga whatiwhatinga tīhaetia.

kino ki tendons

whakamana Investigation o te iohere turi e i roto i te rererangi sagittal me axial. Ko te tuatahi o enei huringa e feruri mārama ake. whakapumautia kino te ki te kitea te tohu MR whai i roto i atahanga te kōwarotanga autō:

• effusion iohere takotoranga (he whakautu nui ki te kikī) ranei edema peritendinoznoy i roto i te kiko synovial (i roto i te hunga wāhi i reira kahore membrane);
• thickening thinning o te iohere ranei;
• rerekētanga tohu (ki māuiuitanga degenerative o te rohe iohere pokapū takina ōna maama, āhuatanga e tohu hyperintensive i T1-VI);
• iohere tonu whaturama (rēhita whatiwhatinga iohere thickening ki rereke kaha tohu me te aratau karekare).

piere wheua

Etahi o nga wharanga tino noa - he wheua whati e hanga te tahi turi. Ki te kite piere pono he hekenga rārangi o te tohu ki te whati o te wheua cortical. I te tahi taime ngā whatiwhatinga. pea te reira i hemarthrosis - toto ki te kōhao tahi. Ko runga i ngā whakaahua T1-taimaha faaite te tohu teitei whakaritea ki te inu serous.

He ma'i (roa-tu) piere Ngā taa'eraa, no te mea etahi iwi i muri i te fariiraa i kino, e kore e rapu i te tauturu ngaio. Hoki taua whara hypointense āhuatanga, huringa nonuniform ki nga tohu o kaiota sclerosis kiko, me te wāhi medullary.

Ko reira utu whakaaro me te contusion whara (karawarawa) wheua. He aha e te turi MRI i roto i enei take? I roto i enei wharanga puta intraosseous iti ngawhatanga. Kei te āhuatanga i te reira na roto i te haaparare i te maturuturunga iho tohu ngoikore i runga i ngā whakaahua T1-taimaha me te hua o tona kaha i runga i ngā whakaahua T2-taimaha. Ka taea te rongoa tohu pathological mō te 3-10 marama.

I roto i te mutunga, ko reira ia tapao e whara te tahi turi te atu pinepine. Ko tētahi o nga tikanga pai mo te tātaritanga o pāpaka rerekē he atahanga te kōwarotanga autō. He maha ngā painga. Tuatahi, ko te nui o ngā mōhiohio i tēnei rangahau. āhei te reira i ngaio ki te aromatawai i te huru o te wheua, me te kopa ngohengohe. Tuarua, he kinokore hoki tūroro te atahanga te kōwarotanga autō (i roto i te ngaro o contraindications). Ko tenei he aha te whakaritea MRI o te turi mō ngā tamariki me ngā pakeke.
