Elastography uye Kuti Inobatsira sei Kuongorora Kenza Yebonde

Chii chinonzi elastography uye chii chingave chakaita mucheterecheti yepabonde?

Iwe usati wagona kenza yemvere , iwe unofanira kuzviwana. Kuongorora makondombera ezemazamu mangwanani-kare kunogona kuponesa hupenyu uye kuderedza kusagadzikana uye kurwara kunowanzoperekedzwa nehutano.

Chii Chinonzi Elastography?

Saka, kwemakumi emakumi emakore, vatsvakurudzi vakaedza kutsvaga nzira dzepamusoro dzekuona kenza yemazamu. Muna 1980, vanenge makumi mana pavakadzi vashanu vese vakabata kenza yemazamu vakawana bundu pachavo. Kunyange zvazvo mucheche kuzviongorora kuchiri kukosha, kazhinji kenza yemazamu nhasi inowanikwa apo mukadzi ane mammogram , ultrasound kana MRI (magnetic resonance imaging).

Asi kunyange apo muedzo unoratidzira chikafu chinonyunyuta, nzira chete inogamuchirwa nhasi kuti uwane chokwadi kana iri kenza ndeyekuita mazamu emvere . Ultrasound uye MRI kufungidzira zvinogona kuona kuti madzimai maduku mune vamwe vakadzi vari nani kupfuura mammogram, asi anoratidzawo kuchena uye zvirwere zvinouraya.

Ichi ndicho chikonzero chimwe chete chinenge chechina pane zvishanu zvese zvese zvechifu chinoratidza kuti nzvimbo inenge yafungidzirwa yakanga yakaipa . Mune mamwe mazwi, 80% ye biopsies inongoda chete kutonga kunze kwekenza.

Kuvhiyiwa kunobatanidza ne-biopsies inodhura uye inosanganisira zvinetso zvayo. Saka, kwemakore mazhinji, vakadzi nevanachiremba vavo vakatarisira chirwere chekuongorora chinogona kuona zvose zviri mukati memazamu uye kutaura kana kuti kwete chekenza, pasina chirwere chinoparadza. Pashure pemakumi maviri emakore ekutsvakurudza, nzira itsva itsva inonzi elastography inogona kuva yakagadzirira kuzadzisa tariro iyoyo.

Elastography - Inoshanda Sei?

Elastography inobatanidza ichangopfuura mukwanisi yekugadzira imaging ye ultrasonic ine yekare kare iyo yekuongorora kenza yemazamu: kubata . Apo mukadzi kana chiremba wake anowedzera pazvipfuva zvechifuva kuti anzwe nezvemhando dzisina kujairika, anogunzva mazamu nehuwandu hwemasimba. Simba iri rinoita kuti chifuva chemuzamu chifambe nenzira inofanirwa. Izwi rinoshandiswa nenzira yekuti nzira yakasimba inopindura musimba inonzi kusununguka. Kana iwe wakambonzwa musana une tumarara yekenza pamusoro pehumwe hukuru, unoziva kuti tumarara inowanzoona sechinhu chakaoma, chisina kugadzikana, chinenge chakaita sedombo kana gomba rechekisi. Masayendisiti anotaura kuti zvipembenene zvine kenza zvinoderera zvikuru-hazvisi kuchinja maitiro kana zvichinyorwa. Icho chinhu chinoita kuti elastography ishande.

Cikiti Sayenzi Kuratidza - Elastography Inoshanda Sei?

Kuti titsanangure kuti elastography inoshanda sei, takapinda mukicheni tikaita jell-O ® chigadziko chaine-machungwa, lime, mandimu, uye marashiro emufukisi, ose ane mavara akasiyana. Isu tinoisa amondimusi pakati pemononi uye sitirobheni zvigadziro kuti zvimirire chinhu chakaoma chakadai semarara.

Elastography Kuzviratidza Kuenderera mberi

Apo patakatora gelatin kubva muchiganda ndokuchiisa pachigamba, zvikamu zvakagadzira mitsetse yakajeka yakadzika:

Iroamondi haifaniri kuchinja maitiro (kana ichiita sokuti inodaro, izvi zvinokonzerwa nekusavheneka kwemaziso kuburikidza negelatin). Asi iyo inowedzera kushanduka (yakasununguka) gelatin inonamatira pasi pekumanikidzwa nokuti yakanyanyisa kupfuura yakamondi.

Ko Elastogram Inoitwa Sei?

Kuti atore "elastogram" yezamu, kutanga unyanzvi hwema ultrasound mifananidzo mifananidzo . Kazhinji zvipfuva zvemazamu zvine zviduku zvakaratidzwa mumifananidzo ye-ultrasound, uye izvi zvinoshanda sechimiro chechimiro chezvinobva zvinotevera. Kana paine mavhinga, izvi zvicharatidza zvakare, asi kusvika ikozvino chimiro che ultrasound hachiudze chiremba chimwe chinhu kunze kwekuti pane zvinenge zvichinyunyuta, izvo mammograms anoitawo saizvozvo.

Danho rinokosha rinotevera. Chishoma chiduku chinotungamirirwa chinoshandiswa kune chifuva, zvakakwana kuti chiendese zvishoma. (Izvi zvinogona kunge zvishoma kudarika iwe unogamuchira apo mazamu ako anonyudzwa kuti atore mammogram anowanzogadzirwa.) Nokudzvinyirirwa kushandiswa (funga "spoon pamusoro pegelatin"), iyo inotora imwe chimiro chekushandiswa. Zvadaro, purogiramu yekombiyuta inofananidza zvifananidzo zviviri uye inogadzira mepu inoratidza kushandiswa kwenzvimbo dzakasiyana. Iyi mepu, inonzi "elastogram", inobudirira zvikuru mukuzarura mazamu akaoma, asingagoni kuchinja, ayo anowanzoda nguva dzose kanaya. Iyo inonyanya kushanduka mabheji inowanzobata bhendi.

Elastography - Zvitsva uye Ramangwana reBearcer Diagnosis

Vatsvakurudzi vezvikamu zvakasiyana-siyana muEurope uye United States vakagadzira elastography nzira dzekenza yepabonde nezvimwe zvinangwa kubvira pakutanga kwema1990. Nzira mbiri dzekutanga dzinotumidzwa se-compression-based elastography (kana kuti ruoko rwokusununguka) uye shear wave wave elastography.

Mune zvidzidzo zvishomanana, maitiro aya ave akakwanisa kuzivisa kana chiremera chichange chiine bhenekeri paine biopsy inenge 90% yenguva. Pakave nehuwandu hwemashoko emanyepo (apo tumoramine inorwara inotarisa yakaipa) uye zvisina kururama (kana chirwere chinoratidzika sechinonyanya kurwisa uye chinonyanya kurwisa). Pane kumwe kunetseka kuti mazamu e "soft" anonzi mucinous carcinoma angakonzera kusava nehana, uye "zvakaoma" zvipembenene zvebonde zvakadai se fibrous adenomas zvinokonzera zviratidzo zvenhema, uye pfungwa idzi dzichiri kuongororwa.

Pasi pose, zvidzidzo zvemashure zvinoonekwa zvakavimbiswa kwazvo, nekuongororwa kwekupedzisira kwemabhuku ekugumisa kuti kushandiswa kwe elastography kunogona kubatsira kutungamira nzira yekusiyanisa zvirwere zvakashata uye zvinotyisa munguva yemberi.
