Chii MRI pamusoro ibvi muhudyu sezvo kuita kuti zvichaita MRI of ibvi?

The ibvi vagari ndiyo vanotambura zvetsandanyama nemapfupa dzevanhu hurongwa. Ndokusaka chirwere kuti ibvi kukuvara - ndiro dambudziko chairo Traumatology. Akakodzera ibvi kwemajoini kuri unyanzvi anonzi rinobva resonance kuri (MRI). Narwo unogona rokuongorora akasiyana-siyana kukuvara, kutangira nemarunda zvakabvaruka uye nekuguma mitswe. Chii MRI pamusoro ibvi? Sei Scans sei? In nyaya idzi kuti arongwe panze.

Anatomy of ibvi muhudyu

remubatanidzwa ichi ndicho chikamu chikuru mumuviri womunhu. Bone ibvi nheyo - ndiye femur uye tibia uye patella. Fibula haana chokuita pejoinhi. Pemvura pfupa Anoumba remubatanidzwa akafukidza shwashwa. Pamusana nayo zvinoderedza mvongamupopoto simba uye zvakanaka kufamba kunosimbiswa.

Panguva distal mugumo wenyika femur ane mbiri condyle - lateral (yakaderera) uye medial (guru). Vane kumativi chimiro. Condyles ikoko panguva proximal kuguma tibia. Zvinoitika sandara. Pakati kuberekesana hukawanika ndivo menisci (wokunze uye yomukati) - falcate shwashwa. Ivo pakudzikamisa ibvi, akaita basa kuvhunduka absorb mairi.

The ibvi vagari oga mabote vanoverengeka kuona utsigo yaro:

• tibialis (medial) koratararo;
• fibula (lateral) koratararo;
• Anterior cruciate;
• posterior cruciate.

The maumbirwo anosanganisirawo ibvi mudzira. Usati funga MRI of ibvi muhudyu, izvo zvinoratidza zvinokosha kuziva kuti kakawanda zvakakanganisa ari mudzira ari quadriceps netsandanyama. kwemasikati yake yakafanira pakarepo marwadzo tsandanyama. Dzimwe nguva Kukuvara vari panoonekwa uye yakafara gobvu mudzira iliotibialnogo turakiti. maumbirwo Iri simba lateral simba Kudzikamiswa yacho ibvi rwakashodoka.

Zvairatidza kuti MRI

Kukuvara zvivako zviri ibvi kuitika kazhinji. The vanachiremba uyo zvikurukuru kutsvaka vechidiki vaitungamirira chinoshingaira mararamiro uye muviri. Asati urongwa kubatsira vanachiremba kuitwa chinhu MRI. Izvi yakarurama uye yakavimbika nzira nokuda nechirwere kukuvara siyana.

In MRI of ibvi, pane zvimwe zviratidzo. Idzi dzinosanganisira:

• zvinogoneka kukuvara rubatso uye cruciate nemarunda;
• kutyora kuvimbika meniscus kana nemarunda;
• vanofungidzirwa kutsemuka;
• kurwadziwa ibvi;
• Specification ruzivo vakawana kuburikidza radiography.

Contraindications kuti kudzidza

"Chii vachatitaka MRI of ibvi muhudyu uye tsoka?" - mubvunzo kuti iyo mhinduro inogona kutsvaka, kwete vanhu vose, nekuti nzira iyi nechirwere varipo contraindications:

• pamberi pacemaker (pacemaker), mashandiro rinogona kutyorwa nokuda kudzidza;
• seari pasi ropa midziyo simbi clip anogona zvava nokuda pokudzora remagineti;
• dambudziko murwere;
• claustrophobia;
• ferromagnetic anodyara nokuda izvo zvakazofamba kunyatsoti kwakarurama mifananidzo vakamonyanisa migumisiro pakutsvakurudza;
• pamuviri kusvika vhiki 12.

Kubva pasi ichi tinofanira kutaura claustrophobia. Hazvisi semhedziso contraindication. Kana kuratidzwa murwere kutya yakavharwa uye vakanovharirwa nzvimbo kushandisa nyaradzo kana yokutindivadza haisi rakadzika.

kuitisa tsvakurudzo

Sei MRI of ibvi - rinopisa nyaya vanhu, vanogadzwa nomudzimu nzira iyi. Saka asati achiita MRI varwere kupa kupfeka chaiyo nguo. Unogona kugara zvinhu zvavo, kana vasina simbi mabhatani, zippers. Pamberi kudzidza kuda kubvisa zvose zvishongo Sunglasses, wachi, bvisa kubva muhomwe makiyi, serura.

Kushanda pakuvheneka rinoitwa murwere supine. Makumbo anoiswa mukati chiridzwa. Munguva chidzidzo hunenge gumbo riri redhiyo Frequency coils. Healthy muzvidimbu zvinofambirana nazvo. Under akaongorora gumbo riri dutu diki chinotenderera. Zvakafanira kuti zvakanaka Visualization yacho cruciate shwashwa.

Kana paine fungidziro yokuti kuvapo bundu, ipapo akaita musiyano MRI. Usati achiedza ari tsinga munhu murwere chinotarisirwa rinokosha fuma. Zvakakodzera nechokwadi kuti ibvi MRI yakaratidza bundu.

MRI anatomi of ibvi muhudyu

Nokuti yakarurama zvokuongorora zvinokosha kuziva kuti MRI tigokuzivisai ibvi kunowanikwa. Hekuno rondedzero chikuru zvinoumba ibvi:

1. In zvisingatomboiti Anterior cruciate shwashwa pamusoro T2-T1 uye VI-VI sokunge mamiriro dema ane homogenous pasi chiratidzo zvikuru. Posterior cruciate shwashwa ari mifananidzo yaunganidzwa MRI, zviri mufanidziro muchimiro yakajeka homogeneous dema tambo.
2. Tibial uye fibular rubatso shwashwa anowanzoita akapa T2-T1 uye VI-VI homogeneous pasi umbirimi chiratidzo.
3. Normal menisci pamusoro T2-T1 uye VI-VI mufanidziro sezvo homogeneously hypointense zvivako (kusvika nhema) pamwe nechepakati tsinga mwanda nemidziyo ropa. The contours of menisci zvakajeka, pamusoro pemvura iri inotsvedzerera.
4. Nemarunda kazhinji yakaderera chaizvo yokusafa chiratidzo. Vanogona kunyange regai kuripa mifananidzo yakaturikwa pana T1 uye T2.
5. Articular shwashwa kunoratidzwa yakaderera chiratidzo kuchinyanya pazuva T2-VI uye avhareji chiratidzo kuchinyanya pazuva T1-VI.

shwashwa kukuvadzwa

Rakajairika kukuvara shwashwa ndiyo Anterior cruciate. MRI inoratidza kuti ibvi vadyi wakaremara mamiriro ichi? At kwemasikati yakawedzera chiratidzo kuchinyanya mukati peboka. Pangava discontinuity kana kusavapo inowanzotorwa chiratidzo. Kana kukuvara itsva kuoma ne MRI zvabuda infer kuvapo kana kusavapo yokumbozorora, nekuti kana shwashwa kukuvara kunowedzera kukura (kune kuzvimba).

Kukuvara rubatso shwashwa angava kuregawo zvachose, zvishomanana misodzi uye intraligamentous pakakoromoka. Kana ukaona munhu akakanganisa tibial rubatso shwashwa, ipapo zvichava kuonekwa thickening. migove pachena kuwedzera chiratidzo. Izvi ndizvo zvinoratidza ibvi MRI Nezuva rokutanga. Zvadaro, zvikamu izvi inonyangarika nokuda Absorção de Água yebongozozo mvura iri dzakapoteredza zvinokuvadza tishu.

Hwatsvuka fibular rubatso shwashwa chirwere, kazhinji mashoma chaizvo. Kukuvara kwakadai ikashandiswa pamwe muhombe comminuted mitswe ari tibial condyle mapfupa kurasikirwa yakapoteredza nyoro munyama.

kuvadza menisci

Nokuti kukuvara zviri ibvi pamwe zvivako zviri kuonekwa zvikuru mashoko mifananidzo vakawana muna sagittal uye in coronal ndege. Kuongorora chii vachatitaka MRI of ibvi, uye chirwere, vanachiremba tisasiya zvinotevera unhu:

• meniscus kukura;
• configuration kwavo, hunhu chiratidzo;
• Ukobvu uye kudzika dzakachinjwa chiratidzo;
• localization Kuchinja mukati meniscus.

Ziva zvakawanda madhigirii kukuvara meniscus :

1. First dhigirii - unexpressed nechepakati degeneration. Munguva MRI kuchinja aonekwa mukati meniscus. Vanoratidza kunowedzera chiratidzo zvikuru.
2. dhigirii Second - vanowanzochema nechepakati degeneration. Inside the meniscus rakashandurwa yakakura munharaunda yakawedzera chiratidzo zvikuru.
3. dhigirii wechitatu - kubvaruka meniscus. Inside the meniscus kwakaratidza rakawedzera chiratidzo zvikuru. The gandiwa pamusoro intra-articular nzvimbo wakaputsika. Dzimwe nzvimbo meniscus zvimedu.

kukuvara nemarunda

Kuongorora zviri ibvi mudzira rinoitwa munyika sagittal uye axial ndege. Chokutanga kuchinja aya mufanidziro zvakanyatsojeka. Damage inoonekwa kana zvinotevera MR zviratidzo dzakaonekwa panguva rinobva resonance kuri:

• effusion mudzira mumuhara (imwe kunyanyisa Kupindura zadzisa) kana edema peritendinoznoy mu synovial zvinyama (munzvimbo idzi apo pasina Kamudzira);
• thickening kana rive dete of mudzira;
• chiratidzo kushanduka (pamwe chinopedza zvokurwara zvomusoro mudzira nzvimbo kurondwa longitudinally Kupenya, dzinoratidzwa hyperintensive somureza pamusoro T1-VI);
• azere mudzira atsamwira (vakanyorwa thickening mudzira zvimedu pamwe zvakachinjwa chiratidzo zvakanyanya uye Wavy gandiwa).

pfupa mitswe

Vamwe rakajairika zvinokuvadza - a mapfupa yakaputsika kuti vanoumba ibvi rwakashodoka. Kana mitswe wechokwadi akaona Linear kuderera ari chiratidzo pamwe yokumbozorora pamusoro cortical mapfupa. Dzimwe nguva misha zvimedu. Kungava hemarthrosis - ropa munzvimbo pamwe mhango. Zviri pamusoro T1-weighted mifananidzo kuratidza yepamusoro chiratidzo kufananidzwa serous mvura.

Zvikurukuru chaikoshawo vane chirwere (Refu) mitswe, nokuti vamwe vanhu pashure pakugamuchira zvakakanganisika, regai kutsvaka kubatsirwa navanachiremba. For Kukuvara vakadaro dzinoratidzwa hypointense, nonuniform kuchinja zviratidzo fibrous zvinyama sclerosis medullary nzvimbo.

Zvakakodzera kufunga uye contusion zvinokuvadza (mavanga) mafupa. Ko MRI ibvi muzviitiko izvi? Mukunyombwa izvi zvichiitika intraosseous shoma kuzvimba. It kunoratidzwa diffuse simba chiratidzo ichidonhedzera pamusoro T1-weighted mifananidzo uye zvibereko kuchinyanya kwayo T2-weighted mifananidzo. Pathological chiratidzo inogona inochengeterwa 3-10 mwedzi.

In mhedziso, zvinokosha kuziva kuti ibvi vadyi wakuvadzwa kakawanda. Imwe yenzira kuti chirwere kuti maronda akasiyana iri rinobva resonance kuri. Rine wandei zvakwakanakira. Chekutanga, tsvakurudzo ichi chinodzidzisa chaizvo. Inoita Nyanzvi kuongorora mamiriro mapfupa uye akapfava munyama. Chechipiri, kuti rinobva resonance kuri hakukuvadzi varwere (tisina contraindications). Ndokusaka basa MRI of ibvi vana uye vakuru.
