I-Cerebral scintigraphy: yintoni, yenzelwe ntoni kwaye yenziwa njani

I-Cerebral scintigraphy, elona gama lichanekileyo yi-cerebral perfusion tomography scintigraphy (SPECT), luvavanyo olwenziwe ukukhangela utshintsho ekujikelezeni kwegazi kunye nokusebenza kwengqondo, kwaye kuhlala kusenziwa ukunceda ekuchongeni nasekubekweni esweni kwezifo zobuchopho, ezinje nge-Alzheimer's, Parkinson's okanye ithumba, ngakumbi xa ezinye iimvavanyo ezinjengeMRI okanye iCT scan zingonelanga ukuqinisekisa ukukrokrelwa.

Uvavanyo lwe-cerebral scintigraphy test lwenziwa ngenaliti yeziyobisi ezibizwa ngokuba zii-radiopharmaceuticals okanye ii-radiotracers, ezikwaziyo ukuzilungisa kwizihlunu zobuchopho, zivumela ukwenziwa kwemifanekiso kwisixhobo.

I-Scintigraphy yenziwa ngugqirha, kwaye inokwenziwa ezibhedlele okanye kwiikliniki ezenza iimviwo zamayeza enyukliya, ngesicelo sonyango esifanelekileyo, nge-SUS, izivumelwano ezithile, okanye ngendlela yabucala.

Yenzelwe ntoni

I-Cerebral scintigraphy ibonelela ngolwazi malunga nokufakwa kwegazi kunye nokusebenza kwengqondo, iluncedo kakhulu kwiimeko ezinje:

• Khangela i-dementias, efana ne-Alzheimer's okanye i-Lewy ye-corpuscle dementia;
• Ukuchonga ukugxila kokuxhuzula;
• Vavanya amathumba engqondo;
• Ncedisa ekuchongeni isifo sika-Parkinson okanye ezinye ii-syndromes zeparkinsonia, ezinjengesifo sikaHuntington;
• Uvavanyo lwezifo ze-neuropsychiatric ezinje nge-schizophrenia kunye noxinzelelo;
• Yenza uxilongo kwangoko, ulawulo kunye nokudaleka kwezifo zobuchopho zemithambo ezinje ngokubetha kunye nezinye iintlobo zemivumbo;
• Qinisekisa ukufa kwengqondo;
• Ukuvavanywa kokulimala okwenzakalisayo, i-hematomas yangaphantsi, amathumba kunye neemeko zokungalunganga kwe-vascular;
• Ukuvavanywa kwesilonda esidumbisayo, esifana ne-herpetic encephalitis, systemic lupus erythematosus, isifo sika-Behçet kunye ne-encephalopathy enxulumene ne-HIV.

Rhoqo, kuyacelwa ubuchwephesha bobuchopho xa kukho amathandabuzo malunga nokuchongwa kwesifo se-neurological, kuba iimvavanyo ezinje nge-magnetic resonance kunye ne-computed tomography, njengoko zibonisa utshintsho ngakumbi kulwakhiwo nakwi-anatomy yethishu yengqondo, isenokungonelisi ukucacisa amanye amatyala .

Kwenziwa njani

Ukwenza i-scintigraphy ye-cerebral, akukho lungiselelo luthile luyimfuneko. Ngosuku loviwo, kuyacetyiswa ukuba isiguli siphumle kangange-15 ukuya kwimizuzu engama-30, kwigumbi elithe cwaka, ukunciphisa uxinzelelo, ukuqinisekisa umgangatho woviwo olungcono.

Emva koko, i-radiopharmaceutical, ihlala i-Technetium-99m okanye i-Thallium, isetyenziswa emthanjeni wesigulana, ekufuneka silinde ubuncinci iyure enye de into igcinwe kakuhle kwingqondo ngaphambi kokuba kuthathwe imifanekiso kwisixhobo kangangemizuzu engama-40 ukuya kuma-60. . Ngeli xesha, kufuneka uhlale ungashukumi kwaye ulale phantsi, njengoko intshukumo inokuphazamisa ukwenziwa kwemifanekiso.

Emva koko isigulana siyakhululwa ukuba senze imisebenzi yesiqhelo. Iiradiopharmaceuticals ezisetyenzisiweyo azihlali zibangela ukusabela okanye nawuphi na umonakalo kwimpilo yomntu owenza uvavanyo.

Ngubani ongafanelekanga

I-Cerebral scintigraphy iyaphikiswa kwabasetyhini abakhulelweyo okanye abancancisayo, kwaye kufuneka baziswe xa kukho nasiphi na isikrokro.
