Kureva kuti, dai taigona kugadzirisa zvinhu izvi pasina kuvhiyiwa kana kusagadzikana kwakanyanya? Ndizvo zvinoita bvunzo iyi inonzi elastography. Ngatitaurei nezvazvo zviri nyore, nenzira yaunogona kunzwisisa.

Chii chinonzi elastography, muchidimbu?

Zvichitaurwa zviri nyore, elastography ibvunzo risingarwadzi rinoyera kuchinjika, kana kuti "springness," kwenhengo dziri mumiviri yedu, dzakadai sechiropa. Fungidzira, patinosarudza muchero, tinoudzvanya zvishoma nemaoko edu kuti tione kana wakasimba kana kuti wakapfava? Izvi zvakafanana, asi netekinoroji yepamusoro-soro.

Bvunzo iyi inoshandisa kutenderera kushoma. Kutenderera uku kunotumirwa kuburikidza nenhengo dzedu uye kunoyera kuomarara kwadzo. Nekuti dzimwe nguva, kana nhengo dzedu dzikaoma zvisina kufanira, kureva kuti, kana kuchinjika kwadzo kukadzikira, zvinogona kuva chiratidzo chechirwere. Kuomarara uku chiratidzo chakakosha, kunyanya muzvirwere zvine chekuita nechiropa.

Kune mhando dze elastography here?

Ehe, kune mhando mbiri dze elastography.

1. Ultrasound Elastography (Elastography Ultrasound) kana FibroScan®

Izvi zvinonziwo transient elastography nevamwe. Ungave wakambonzwa nezveFibroScan®. Ndizvo zvazviri. Zvakafanana chaizvo nebvunzo ye ultrasound .

• Muizvi, mudziyo mudiki unobatwa nemaoko ('transducer') nemafungu eruzha zvinoshandiswa kuwana mufananidzo wenhengo dzako.
• Izvi hazvirwadzi zvachose, uye zvinokurumidza. Chinhu chinogona kuitwa nekukasika.

2. M.R. Elastography (MRE - Magnetic Resonance Elastography)

Izvi zvinosanganisira kusanganisa mafungu eruzha kubva kuultrasound nemagineti nemafungu eredhiyo kubva kuMRI (Magnetic Resonance Imaging) scan kuti uwane mifananidzo yakajeka yenhengo dzako.

• Chinhu chinonyanya kukosha ndechekuti hapana radiation inoshandiswa mune izvi.
• Dzimwe nguva chiremba anogona kusarudza kuita bvunzo iyi yeMRE ega, kana kuti inogona kuitwa pamwe chete nekuongorora kwakazara kweMRI.

Chii chinonzi 'shear wave' elastography iyi?

Iyi inyanzvi itsva ye ultrasound. Inoshandiswawo kuyera kuomarara kwenyama dzenhengo.

• Unoyeuka here mudziyo uya unobatwa nemaoko ('transducer')? Unotuma mapulse ane simba guru. Mapulse aya anogadzira rudzi rwakakosha rwemafungu anonzi 'shear waves'.
• Mafungu aya anobvumira mifananidzo yemhando yepamusoro uye yakajeka .
• Kunyangwe tekinoroji iyi ichiri kuvandudzwa, iri kutoshandiswa pakuongororwa kwe ultrasound. Semuenzaniso:
• Kuongororwa kwezvemazamu
• Chiropa
• Sisitimu yetsandanyama
• Prostate
• Tarisa kana paine maronda e thyroid.

Saka, sei bvunzo iyi ye elastography ichiitwa?

Chikonzero chikuru uye chinonyanya kukosha chekuita bvunzo iyi ndechekuona kana uine chirwere chinonzi fibrosis, kana kuti mavanga echiropa. Fibrosis ingori mavanga echiropa. Izvi zvinogona kuitika pakutanga uye, kana zvikarapwa zvakanaka, zvinogona kutungamira kuchirwere chakakomba chinonzi cirrhosis.

Kana uine zvinhu zvinokonzera chirwere checirrhosis, kana kuti uri kuratidza zviratidzo zvechirwere ichi, chiremba wako anogona kukurudzira kuti uedze elastography.

Zvakakosha: Fibrosis inogona kuderedza huwandu hweropa rinopfuura nemuchiropa. Nekufamba kwenguva, ropa iroro rinogona kutanga kuungana kumashure kwechiropa. Kana izvi zvikarapwa zvakanaka, zvinogona kukonzera matambudziko makuru ehutano.

Matambudziko akadaro ndeaya:

• Kurwara neCirrhosis
• Kenza yechiropa
• Kukundikana kwechiropa
• Kubuda ropa mudumbu

Saka, elastography inobatsira zvikuru vanachiremba kusarudza kuti rudzii rwekurapa rwakakodzera fibrosis yechiropa. Kwete izvozvo chete, kana uri kutora kurapwa, bvunzo iyi inogonawo kubatsira kuona kuti chiropa chako chiri kupindura sei kurapwa ikoko uye kufanotaura mukana wematambudziko akadai sekuunganidzwa kwemafuta muchiropa.

Ndiani anoita bvunzo idzi dze elastography?

Elastography Ultrasound neMRE zvinoitwa nenyanzvi yeX-ray , chiremba ane hunyanzvi mukugadzira mifananidzo yezvokurapa. Vanowanzo shanda pamwe chete nenyanzvi yako huru yekurapa, nyanzvi yekenza, uye nyanzvi yehepato.

Kuongororwa kwechiropa ne elastography kwakarurama zvakadii?

Kunyangwe paine zvidzidzo zvakasiyana-siyana panyaya iyi, vanachiremba vazhinji vanobvumirana kuti elastography inzira chaiyo yekuongorora fibrosis yechiropa. Kutaura zvazviri, vanachiremba vazhinji vanoshandisa nzira iyi yekuongorora chirwere ichi. Chinonyanya kukosha ndechekuti inoshandiswawo kutarisa kuti chirwere ichi chiri kuramba chichikura kana kuti chichidzorwa sei nekufamba kwenguva.

Kuedzwa uku kwe elastography kunoitwa sei?

Maitiro ekuita izvi anosiyana zvishoma zvichienderana nerudzi rwebvunzo.

Maitiro ekuita Transient Elastography:

Izvi zvinongotora maminetsi mashoma chete. Zvinokurumidza zvikuru.

• Kutanga, chiremba weX-ray achaisa gel ine mvura panzvimbo yeganda rako ichaongororwa. Izvi zvichaita kuti mudziyo unobatwa nemaoko ('transducer') ufambe zviri nyore pamusoro peganda.
• Chiremba weX-ray anobva afambisa transducer pamusoro peganda rako kuti awane nzvimbo chaiyo yenhengo yaunoda kuongororwa.
• Zvino, transducer iyoyo inotumira kutenderera kusingarwadzi uye kusingadzoreki mumuviri.
• Kudedera uku kunorova nhengo yakakodzera uye kunodzokororwa. Ruzivo irworwo runoenda kukombiyuta.
• Kombiyuta inoshandisa ruzivo urwu kugadzira `mufananidzo` wenhengo yakakodzera.
• Nekutarisa mufananidzo uyu, chiremba we radiation anogona kuona chaizvo kuti nhengo yacho yakaita sei, saizi yayo, chimiro chayo, uye mamiriro ayo - ndiko kuti, kuti yakasimba sei, kana yakazadzwa nemvura, nezvimwewo.

Maitiro ekuita MRE:

Kuongororwa kweMRE kunowanzo tora maminetsi mashanu. Zvisinei, kana uri kuzviita neMRI scan yakazara, zvinogona kutora nguva yakati rebei, maminetsi angangoita makumi mana nemashanu. Hezvino zvinoitika kana wawana MRE:

• Uchaitwa kuti urare patafura. Unogonawo kupiwa tambo dzinokubatsira kuti usanyanye kugadzikana.
• Chishandiso chidiki, chinonzi `driver`, chinoiswa pasi peganda kurudyi rwechipfuva chako, pazasi chaipo (kana uri kuongorora chiropa MRE).
• Kune zvimwe zvishandiso, zvinogona kutumira nekugamuchira mafungu eredhiyo, zviri padyo ne'driver'.
• Kana ukapihwa mushonga wekuenzanisa (chinhu chakakosha, senge gadolinium) cheMRI, chinobayiwa kuburikidza nemutsara weIV wakaiswa mutsinga iri muruoko rwako.
• Wobva watumirwa kumuchina weMRI. Muchina wacho unoita sechubhu diki.
• Chiremba weX-ray anodzora zvese izvi kunze kwemuchina weMRI, akagara pakombuta.
• Mutyairi anotumira kudedera kudiki kuchiropa chako, uye kunyange zvazvo achitora mifananidzo yacho, unokumbirwa kuti ubatisise mweya wako kwemasekondi mashoma.

Unogadzirira sei izvi?

Heano zvimwe zvinhu zvaunofanira kufunga nezvazvo usati waita bvunzo ye elastography:

• Chikafu: Dzivisa kudya zvine shuga nezvinwiwa usati waongororwa. Zvikafu zvine shuga zvinogona kukanganisa mashandiro echiropa. Ungangokumbirwa kutsanya kwemaawa mashoma usati waongororwa. Zvakanaka kubvunza chiremba wako kuti unofanira kutsanya kwenguva yakareba sei.
• Zvipfeko: Pazuva rebvunzo, siya zvishongo zvako, mawachi, mapini ebvudzi, zvinhu zvinobatsira kunzwa, uye mazino emazino anobviswa kumba. Pfeka mbatya dzakanaka, dzisina kusimba.Ungangofanirawo kupfeka gown rekurapa rawakapihwa nechipatara.
• Simbi: Kana uine zvinhu zvesimbi mumuviri wako - zvakaita sezvimedu zvemabara, ma defibrillator ekare emwoyo kana pacemakers - unofanira kuudza chiremba we radiology nezvazvo, sezvo zvinhu izvi zvesimbi zvinogona kukanganisa simba remagineti remuchina weMRI.
• Kubata Pamuviri: Kana uine pamuviri, iva nechokwadi chekuti waudza chiremba wako nenyanzvi yeX-ray. Elastography inowanzoonekwa seyakachengeteka panguva yekuzvitakura. Zvisinei, zvakanaka kudzivirira kuongororwa kweMRI mumwedzi mitatu yekutanga yekuzvitakura. Zvisinei, kuongororwa kweMRI kunogona kuitwa panguva iyi chete kana chiremba wako akaona kuti mabhenefiti ekuongororwa uku anopfuura njodzi.

Chii chawakasangana nacho panguva yebvunzo?

Chiremba wako weX-ray achakutsanangurira zvese panguva yekuongororwa. Zvese zviri zviviri Elastography Ultrasound neMRE bvunzo dzisingarwadzi uye hadzipindi. Saka hauzonzwi kurwadziwa kana kusagadzikana.

Kana uri kuvhiyiwa MRE, unofanira kugara munzvimbo yakaita sechubhu kwemaminitsi mashoma. Kana uri kuvhiyiwa full MRI, zvinotora nguva yakati rebei, ingangoita maminetsi makumi mana nemashanu. Kana uine claustrophobia, udza chiremba wako ne radiologist yako nguva isati yasvika. Uyewo, gadzirira kumisa kufema kwako kwemasekondi angangoita gumi kusvika gumi nemashanu panguva yeMRE.

Pane njodzi here mune izvi?

• Elastography ultrasound haina njodzi kusvika pari zvino.
• Kana uchiongororwa MRE, kana nzira dzakakodzera dzekuchengetedza dzikatevedzerwa, hapana njodzi kumunhuwo zvake. Simba remagineti harikuvadzi. Zvisinei, kana ukapihwa mushonga wekukonzera hope (`sedation`), panogona kunge paine njodzi dzinoenderana nekupa mushonga wakawandisa. Uyewo, pane mukana mudiki wekuva neallergy kune `contrast` fluid` inonzi `gadolinium`, iyo inoshandiswa chete kune dzimwe bvunzo dzeMRI.

Mhedzisiro yerudzii inowanikwa? Inotiudzei?

Kuongororwa kwako kwe elastography kunotora mufananidzo wechiropa chako. Chiremba we radiologist anogona kushandisa mufananidzo wacho kukuudza kuti chiropa chako chakaoma sei. Kuoma uku ndiko kuyera kuti chiropa chako chine mavanga akawanda sei. Huremu hwemavanga hunogona kubva pahudiki kusvika pahukanyanya:

• F0 kusvika F1: Hapana kana mavanga madiki.
• F2: Mavanga ari pakati nepakati.
• F3:Mavanga akanyanya.
• F4: Mavanga akanyanya kuoma, ayo anonzi cirrhosis. (Mavanga epamusoro)

Zvinotora nguva yakareba sei kuti uzive mhedzisiro?

Chiremba weX-ray achaona mhedzisiro ye elastography scan yako mukati memazuva mashoma. Vachagovana mhedzisiro yacho nevamwe vanachiremba vakakutumira. Zvadaro, mumwe wevanachiremba vako achakufonera kuti atsanangure mhedzisiro yacho uye apindure chero mibvunzo yaungave nayo.

Muchidimbu (Mharidzo Yekuenda Kumba)

Elastography ibvunzo isingapindi mumuviri inoyera kuomarara kwenyama dziri mukati memiviri yedu. Inowanzo shandiswa kutarisa kana paine fibrosis yechiropa, chirwere chinokonzera mavanga muchiropa. Chiremba wako anogona kuraira bvunzo iyi kana uine kuzvimba kana kukuvara kwechiropa chako, kana kana uine zviratidzo zvecirrhosis.

Bvunzo iyi inowanzo kurumidza uye isingarwadzi, saka hapana chekunetseka nacho. Kana uchida kuziva zvakawanda nezveizvi, taura nachiremba wako uye kumbira rumwe ruzivo. Nenzira iyi, unogona kupindura chero mibvunzo yaungave nayo.
