I-Elastography kunye Nokuba Unceda njani Ukuxilongwa Ngomhlaza Webele

Yintoni i-elastography kwaye yintoni inokuyidlala ngayo ekuhloleni umdlavuza webele?

Ngaphambi kokuba uphathe umdlavuza webele , kufuneka uwufumane. Ukufumanisa iintsholongwane zamathambo kusasa kunokusindisa ubomi kunye nokunciphisa ukuphazamiseka nokugula okuqhelekileyo kuhamba kunye nokunyangwa.

Yintoni i-Elastography?

Ngoko, kwiminyaka emininzi, abaphandi baye bazama ukufumana iindlela ezingcono zokufumana umdlavuza webele. Ngowe-1980, malunga nabesithathu kwabasetyhini abafumana isifo somhlaza webele, bafumana ihlunu ngokwabo. Nangona ukuhlolwa kwebele kusebalulekile, ezininzi iintsholongwane zentsholongwane zifumanisa xa umfazi ephethe i- mammogram , i- ultrasound okanye i-MRI (imagination magnetic resonance).

Kodwa nangona xa uvavanyo lubonakalisa inqabileyo, indlela eyamkelekileyo yodwa namhlanje ukufumanisa ukuba ngaba unomdlavuza ukwenza i-biopsy yamabele . Ukucatshulwa kwe-ultrasound kunye ne-MRI kungafumanisa amancinci amancinci kwamanye amabhinqa angcono kunokuba i-mammogram, kodwa ibonisa ukuba unobungozi kunye nezilonda ezinobungozi.

Esi sizathu esinye sokuba malunga neyesine ezintlanu kwi-biopsies zesifuba sibonisa ukuba indawo ekhankanywe kuyo yayinobungozi . Ngamanye amazwi, ama-80% e-biopsies ayadingeka kuphela ukulawula umhlaza.

Utyando olubandakanyekayo ne-biopsies lubiza kwaye luquka ubungozi balo. Ngoko, iminyaka emininzi, oomama kunye noogqirha babenethemba lokuhlola uvavanyo oluza kubona iziganeko ezinqabileyo ngaphakathi kwebele kwaye uxele ukuba ingaba unomdlavuza, ngaphandle kokuhlinzwa okwangenayo. Emva kokuphengulula iminyaka engamashumi amabini, ubugcisa obutsha obuthembisa ukuba yi-elastography inokulungele ukuzalisekisa lelo themba.

Elastography - Isebenza Kanjani?

I-Elastography idibanisa i-latest technology kwi-teknoloji ye-imaging ye-ultrasonic kunye neyona ndlela endala kunazo zonke zomhlaza webele: ukuthintela . Xa ibhinqa okanye ugqirha wakhe agxininisa izicubu zesifuba ukuze azive ngenxa yeziqholo ezingavamile, uthinta isifuba ngenani elincinci lamandla. Eli gunya lenza ukuba isakhiwo sebele sifakwe ngendlela ephawulekayo. Ixesha lobugcisa kwindlela indlela eqinileyo ehamba ngayo ekuphenduleni umkhosi kuthiwa u-elasticity. Ukuba unake uvakalelwa isifuba ngesifo somhlaza ngaphezu kwesayizi esithile, uyazi ukuba i-tumor ivakalelwa njengexakeka, i-swelling inclexible, efana neliwa okanye ipayipi. Izazinzulu zithi izicubu zesifo somhlaza zinamazinga aphantsi kakhulu - aziguquli ngokuma xa zixinzelelwe. Yiyo le propati eyenza i-elastography isebenze.

I-Kitchen Science Demonstration - I-Elastography isebenza njani?

Ukucacisa indlela i-elastography esebenza ngayo, sasiya ekhitshini kwaye senza i-Jell-O ® isikhombisi sesine-orange, i-lime, i-lemon, kunye ne-flavour flavour, yonke imibala eyahlukileyo. Sifaka i-almond phakathi kwe-lemon kunye ne-strawberry layers ukumela into enzima njenge-tumor.

I-Elastography - Ukuxelela i-Apart Benign kunye nee-Tumor Tumors

I-Elastography Ukubonakalisa okuqhubekayo

Xa sithatha i-gelatin ngaphandle kwesikhunta kwaye siyifake kwisityikiti, iziqulatho zenza imigca ecacileyo ecacileyo:

I-almond ayitshintshi indlela (ukuba ibonakala ngathi yenzayo, kungenxa yokuphazamiseka kwe-optical ngokusebenzisa i-gelatin). Kodwa i-flexible (elastic) i-gelatin iyancipha phantsi kwengcinezelo kuba i-elastic more than almond.

I-Elastogram eyenziwe njani?

Ukuthatha "i-elastogram" yesifuba, okokuqala imifanekiso yemashishini ye-ultrasound eyinkampu . Iifama zesifuba eziqhelekileyo zinempawu ezincinci ezibonisa imifanekiso ye-ultrasound, kwaye ezi zixhobo zisebenza njengamakishi okuba yintoni ezayo ngokuzayo. Ukuba kukho naziphi na izibonda, ezi ziza kubonakala kwakhona, kodwa ngoku umfanekiso wes ultrasound awuxeleli ugqirha nantoni na ukuba kukho izilwanyana ezinokukrokra, ezenza izilwanyana.

Isinyathelo esibalulekileyo siza emva koko. Umlinganiselo omncinci wokuxinzelelo olawulwayo usetyenziselwa isifuba, ngokwaneleyo ukuwuhambisa kancane. (Olu xinzelelo lube luncinci kakhulu kunokuba ufumene xa amabele akho athatyathwa ukuba athathe i-mammogram eqhelekileyo.) Ngoxinzelelo olusetyenzisiweyo (cinga "i-spoon phezulu kwe-gelatin"), inkqubo inomnye umfanekiso wes ultrasound. Emva koko, iprogram yekhompyutha ifanisa imifanekiso emibini kwaye ivelise imephu ebonisa indlela ezithintekayo ngayo imimandla eyahlukileyo. Le mephu, ebizwa ngokuba yi-elastogram, iyasebenza kakhulu ekutyhileni izibilini ezinzima, ezingapheliyo, eziphantse zibe nomhlaza. Izibane eziguquguqukayo ziqhelekile.

I-Elastography - Iziphumo kunye neKamva ye-Cancer Diagnosis

Abaphandi kumaziko amaninzi eYurophu naseUnited States baye baqulunqa ubuchule be-elastography yomhlaza wesifuba kunye nezinye iinjongo ukususela ekuqaleni kwawo-1990. Iiprogram zokuqala ezi-2 zibizwa ngokuba yi-compression based based elastography (okanye i-free-hand) kunye ne-wavear elastography.

Kwiinkalo eziliqela, ezi zixhobo ziye zakwazi ukuxelela xa i-tumor yayiza kuba yinto enobungozi kwi-biopsy malunga ne-90% yexesha. Kukho iinkolelo ezintle ezingamanga (xa i-tumor ebonakalayo ibonakala ingekho embi) kunye neengxaki ezingamanga (xa i-tumor ibonakala ingenangqondo kwaye ingumdlavuza). Kukho inkxalabo yokuba "i-soft" i- cancer yebele ifana ne-carcinoma ye-mucinous iya kubangela ukungalungi kwamathambo, kwaye izibilini ezinzima "ezinzima" ezinjengama-adenom e-fibrous ziza kubangela iingxaki zobuxoki, kwaye ezi ngcamango zisacatshangelwa.

Ngokubanzi, uphando oluya kumhla lubonakala lu thembisa kakhulu, ngokuphononongwa kwangoku kwincwadi equkumbela ukuba ukusetyenziswa kwe-elastography kunokunceda ukukhokela inkqubo yokuhlukanisa izibilini zesifuba ezinobulunga kunye nezibi.
