Yintoni na scintigraphy ithambo asemzimbeni?

Bone scintigraphy skeleton - indlela ezisebenzayo uxilongo lwesifo ithambo. Lo mgaqo uyasebenza kule ndlela kuxhomekeke ukufunxeka olungalinganiyo esiqwini bone iziyobisi eqhelekileyo olungaqhelekanga eqhumayo. Le ichiza yayisalawulwa izilinganiso ukuba alunasiphumo yityhefu kwi umzimba, kodwa oku babizwa ngokuba "ileyibheli" kwi inyama yezifo.

Kukho iintlobo ezininzi amalungiselelo yovavanyo leyo zenzelwe isifundo kweenkqubo zomzimba ethile. kungcono ukusebenzisa amathambo amathambo kunye 99mTc bifosfanaty ezindongeni. Kulo yokulungiselela ubuninzi bangangeni amandla kungena amathambo.

Ngenxa yoko le zokuxilonga scintigraphy amathambo wafumana umfanekiso okuntlandlo-mbini - oku yaneleyo ukungaphili zokusebenza kunye neenkqubo zophendlo lwezifo.

Scintigraphy ngamathambo inokuba log kwezi meko zilandelayo:

- ezisemthethweni zoxilongo oncologic kunye Ukudlulela kunokwenzeka,

- Direct iinkqubo tumoral emathanjeni,

- waphuka,

- njengoko kokwakhelwa Dynamics unyango.

Scintigraphy skeleton oluqhutywa neekhamera gamma ekhethekileyo. Ubume bale ndawo ukuba uyakwazi ukufaka ziluhlaza zincinane, kodwa ukwandisa amaxesha zabo amandla eziliqela kuphela. Onesiphumo kwakhiwa flash esiqinileyo ukukhanya, nto leyo ndifungeleni umatshini ekhethekileyo spectrometric. Ngaloo ndlela kunokwenzeka ukufumanisa ukusasazwa ichiza enombhalo kuwo wonke ummandla amathambo.

Radiopharmaceutical ilawulwa iiyure ezintathu phambi isifundo icetywayo. Yaba ngeli xesha iziyobisi ixesha ekusasazeni egazini ukuba ngokupheleleyo onke amathambo asemzimbeni. Ngoko qhubeka ngqo uxilongo, leyo Nongawuthabathiyo ngaphezu kweyure. Isiphumo ukuyiqikelela phantse nangoko emva kwenkqubo - iluncedo kakhulu zombini umguli kunye nogqirha.

Bone scintigraphy skeleton ngeli xesha - omnye ethandwa kwaye kwafunwa emva kuxilongo ngezifo ithambo. Izinto eziluncedo solu phando:

- imali encinane ixesha nemali le nkqubo;

- kakhulu ulwazi (kukuvumela ukuba ubone imiqondiso yobubi kwi ithambo kwiinyanga ezimbalwa phambi kokuba nokuthelekelela zabo phezu radiograph);

- elula ukuba umguli kunye nokhuseleko ngokupheleleyo.

Kufuneka kuqatshelwe ukuba scintigraphy amathambo wenziwa eUnited States phakathi kunyaka ophelileyo ukuya ku-17 ezigidi. Kwakhona, ukuba usindisiwe,. Ubomi ngaphezu kwezigidi ezili-10. Ngapha koko, ekulweni nomhlaza yeyona ibalulekileyo - isigulo kwangethuba.

Kumazwe Western, scintigraphy ithambo - asiyonto intsha kwaye Akumangalisi, kunoko, indlela eqhelekileyo sifo, oluqhutywa phantse na eklinikhi. Kumazwe aphuhlileyo kakhulu, esi sifundo kucingwa ukuba obutofotofo ufuduswe phandle kuphela kumaziko zonyango enkulu. Izixhobo ishiya kangako - kudla lixesha gamma camera.

Kufuneka iqondwe into scintigraphy zingasetyenziswa kuphela moshilongo izifo ithambo. Eyifumanayo isicelo yayo liphela zentliziyo, ukuze ukubona isifo sentliziyo. scintigraphy engabalulekanga owazenza kunye namanye amachiza eziliqela, kodwa lo mgaqo indlela iyafana.

"Pertechnetate" - enombhalo iziyobisi ezithile ngenxa uxilongo kwezifo lengqula usebenzisa ikhamera gamma.

Kwakhona, kukho iziyobisi ezahlukeneyo radioactive, utshixelo ukuba ijwabu kwemiphunga kunye glomeruli kwezintso. Oku kwenza kube lula ukufumanisa abantu ngezifo ezi nkqubo kwi kwinqanaba lokuqala.

Ngokubanzi, scintigraphy - indlela jikelele lokufunyaniswa ezimbi ezininzi amalungu angaphakathi, yaye, mhlawumbi, kwixesha elizayo kuya kuba eqhelekileyo kakhulu kuwo onke amazwe.
