Xa ugqirha ekuxelela ukuba udinga i-SPECT scan, ngaba woyika okanye unomdla? Kuqhelekile ukuba uzive unzima kancinci xa usiva eli gama. "Luhlobo luni lovavanyo olu? Ngaba luza kuba buhlungu? Kuza kwenzeka ntoni?" Mhlawumbi unemibuzo emininzi efika engqondweni yakho. Kodwa ungoyiki. Namhlanje, siza kuthetha ngale SPECT scan ngendlela elula kakhulu onokuyiqonda. Njengokuthetha nomhlobo.
Ngamafutshane, yintoni i-SPECT scan?
I-SPECT scan luvavanyo olukhethekileyo lomfanekiso olusetyenziswa ngamayeza enyukliya. Kulungile, musa ukoyika igama elithi "nyukliya." Lithatha imifanekiso eneenkcukacha zamalungu angaphakathi emzimbeni wakho. Lisebenzisa into ebizwa ngokuba yi-radioactive substance (radiotracer) .
Cinga ngale ndlela. Ufuna ukubona ukuba ilungu elithile emzimbeni wakho lisebenza kakuhle na kwaye lifumana ukuhamba kwegazi okwaneleyo. I-X-ray eqhelekileyo ibonisa kuphela imilo yezinto ezifana namathambo. Kodwa i-SPECT scan ingabona iinkqubo ezenzekayo ngaphakathi kweso sitho, ingakumbi indlela igazi elihamba ngayo . Oko kuthetha ukuba ayinakubona kuphela imilo yelungu, kodwa nendlela elisebenza ngayo. Kufana nokuqala injini yemoto uze ubone indlela esebenza ngayo, endaweni yokuyijonga nje.
Zeziphi izinto eziphambili ezijongwayo kwi-SPECT scan?
Ii-SPECT scans zisetyenziselwa ukuhlola amalungu ahlukeneyo. Kukho iintlobo ezintathu eziphambili. Masizijonge ngale ndlela.
| Uhlobo lokuskena | Izifo ezichongiweyo kakhulu |
|---|---|
| Iskena sobuchopho se-SPECT | Oku kunceda ekuchongeni utshintsho kwindlela igazi elihamba ngayo kwiindawo ezahlukeneyo zobuchopho. Oku kuvumela ugqirha ukuba aqonde ukuba zeziphi iindawo zobuchopho ezingasebenzi kakhulu nezingasebenzi kakhulu. Oku kubalulekile ekuxilongeni iimeko ezifana nezi:
|
| I-SPECT Heart Scan | Olu vavanyo lusetyenziselwa ukubona ukuba intliziyo yakho isebenza kakuhle kangakanani na. Umzekelo:
|
| Iskena seThambo se-SPECT | Ngamanye amaxesha inokubona iingxaki emathanjeni ezingabonwayo zezinye iintlobo ze-scan. Imizekelo:
|
Ngamanye amaxesha, ugqirha wakho unokuyalela i -SPECT/CT scan ukongeza kwi-SPECT scan. Oku kudibanisa ulwazi oluvela kuzo zombini ii-scan (SPECT kunye ne-CT) ukuze kuvele umfanekiso ocacileyo.
Isebenza njani le scan?
Kukho amanyathelo amabini aphambili kwi-SPECT scan. Kulula kakhulu.
1. Ukufaka into ene-radioactive (Radiotracer) emzimbeni
Okokuqala, ugqirha okanye ingcali eqeqeshiweyo iza kufaka into ekhethekileyo ebizwa ngokuba yi-radiotracer emzimbeni wakho. Oku kunceda iskeni ukuba ivelise imifanekiso ecacileyo. Kufana nokukhanyisa isibane esincinci ukuze ufumane into ethile kwigumbi elimnyama.
- Amaxesha amaninzi, oku kunikwa njengenaliti emthanjeni.
- Kwiimeko ezingaqhelekanga, le nto ingaginywa okanye ifunxwe.
Njengoko le "(radiotracer)" ihamba emzimbeni, iqokelelana kwilungu okanye kwizicubu ezihlolwayo. Indlela eqokelelana ngayo ivumela ugqirha ukuba aqonde indlela elo lungu elisebenza ngayo.
Musa ukukhathazeka! Le `(radiotracer)` ikhuselekile kakhulu. Inemitha encinci kakhulu . Ilingana nomlinganiselo wemitha ofunyanwa ngumzimba xa uthatha i-X-ray eqhelekileyo. Ayinadayi kwaye ayibangeli miphumo emibi. NgokwesiqheloLe nto isuswa ngokupheleleyo emzimbeni kwiiyure ezingama-24.
2. Ukuthatha imifanekiso ngekhamera ye-gamma
Emva kokuba umzimba wakho ufunxe into ekhethekileyo, usiwa kwigumbi apho kukho i-scanner. Apho, ulaliswa etafileni. Emva koko, ikhamera ekhethekileyo ebizwa ngokuba yi-gamma camera ijikeleza kancinci ikujikeleze ize ithathe imifanekiso.
Le khamera ye-gamma ifana nesixhobo sokufumanisa imitha. Ayikhuphi imitha, kodwa endaweni yoko ithatha imiqondiso evela kwi-radiotracer engaphakathi emzimbeni wakho. Emva koko ithumela olo lwazi kwikhompyutha, edala imifanekiso yezitho zakho zomzimba enamacala amathathu (3D).
Ndingazilungiselela njani ngaphambi kokuba ndiskene?
Ugqirha wakho uza kukunika imiyalelo ethile, kodwa ngokubanzi, khumbula ezi zinto.
- Impahla: Nxiba impahla ekhululekileyo nekhululekileyo.
- Ubucwebe: Kungcono ukususa ubucwebe besinyithi obufana neewotshi, imigexo, kunye neebracelets uze uzishiye ekhaya xa usiya kuskena.
Ngamanye amaxesha inaliti ye-`(radiotracer)` inikwa ngaphambi nje kokuba ihlolwe. Kodwa kwezinye iimvavanyo, inokunikwa kwiiyure ezimbalwa okanye kwaneentsuku ezimbalwa ngaphambi kokuba ihlolwe. Ukuba kukho into efana naleyo ifunekayo, ugqirha wakho uya kukwazisa kwangaphambili.
Kwenzeka ntoni ngexesha leskeni?
Iskeni idla ngokuthatha malunga nemizuzu engama-30 . Nangona kunjalo, ngokuxhomekeke kwinxalenye yomzimba eskeniweyo, kungathatha ixesha elide. Okufuneka ukwenze kukulala ungashukumi etafileni. Awuyi kuva ntlungu ngeli xesha lenkqubo. Iskeni ayizukuchukumisa umzimba wakho.
Emva kokuba uvavanyo luphelile, ungagoduka ngaphandle kweengxaki uze uqhubeke nemisebenzi yakho yesiqhelo.
Zithini iingenelo ze-SPECT scan?
- Olu vavanyo lunokwenziwa ngokukhuselekileyo nakubantu abanezixhobo zentliziyo ezifana ne-pacemakers.
- Ingafumanisa ezinye iimeko zempilo ezifihlakeleyo ezingafumanekiyo zezinye iintlobo zeskeni.
- Asifundi nje kuphela ngemilo yezitho zomzimba, kodwa kwanendlela ezisebenza kakuhle ngayo .
Ngaba kukho naziphi na iziphumo ebezingalindelekanga okanye iingozi?
I-SPECT scan ayisebenzisi mitha ingako kakhulu, ngoko ke iingozi zincinci. Akukho mfuneko yokukhathazeka ngayo. Nangona kunjalo, ukuba unemibuzo okanye iinkxalabo malunga nemitha, thetha nogqirha wakho ngayo ngokukhululekileyo.
Ingakumbi umama okhulelweyo okanye oncancisayoUkuba kunjalo, olu vavanyo alukhuthazwa. Kwakhona, kunqabile kakhulu ukuba umntu abe ne-allergy kwi-radiotracer. Ngoko ke ukuba unemeko enjalo, xelela ugqirha wakho kwangaphambili.
Yintoni umahluko phakathi kwe-SPECT, CT kunye ne-MRI scans?
Abantu abaninzi bayadideka malunga nezi ntlobo zeskeni. Masiqonde umahluko ophambili phakathi kwazo.
| Uvavanyo | Iteknoloji esetyenzisiweyo | Yintoni eboniswa kakhulu? |
|---|---|---|
| Iskena se-SPECT | Imitha yeGamma kunye nesithako esinomsakazo (iRadiotracer) | I-Physiology - Indlela amalungu omzimba asebenza ngayo, ingakumbi ukujikeleza kwegazi. |
| Iskena se-CT | Ii-X-reyi | I-Anatomy - Ubume, ubungakanani, kunye nendawo amalungu, amathambo kunye nezicubu. |
| Iskeni yeMRI | Amasimi emagnethi anamandla kunye namaza erediyo | I-Anatomy - Imifanekiso ecacileyo kakhulu, ingakumbi yezicubu ezithambileyo (ingqondo, izihlunu, imisipha). |
Ngamafutshane, ii-CT kunye ne-MRI scans zifana nokuthatha 'ifoto' yamalungu omzimba. Oko kukuthi, zijonga izinto ezifana nemilo kunye nobukhulu bazo. Kodwa i-SPECT scan ifana nokubukela 'ividiyo' , inika ulwazi malunga nendlela loo malungu asebenza ngayo .
Kuthatha ixesha elingakanani ukufumana iziphumo?
Kudla ngokuthatha malunga neveki ukufumana iziphumo zeskeni yakho.Ungahamba. Imifanekiso evela kwiskeni ihlolwa ngononophelo yingcali ye-radiology kwaye ingxelo iyalungiswa. Ingxelo ithunyelwa kugqirha oku-odolele uvavanyo. Ekugqibeleni, ugqirha wakho uza kuyijonga kwakhona ingxelo, axoxe nawe ngeziphumo, aze agqibe kwelokuba loluphi olunye unyathelo olufunekayo, ukuba lukhona.
Umyalezo Wokuya Ekhaya
- I-SPECT scan luvavanyo olukhethekileyo olujonga kungekuphela nje imilo yamalungu akho, kodwa nendlela asebenza ngayo .
- Izinto ezisebenzisa i-radioactive (radiotracer) ezisetyenziswa koku zikhuselekile kakhulu. Ubungakanani bemitha ekhutshwayo buphantsi kakhulu.
- Oku kunceda ekufumaneni izifo ezithile zobuchopho, intliziyo, kunye namathambo ngcono kunezinye iiskeni.
- Akukho ntlungu ngexesha lovavanyo. Kufuneka ulale phantsi ngokukhululeka.
- Ukuba unemibuzo okanye iinkxalabo malunga nolu vavanyo, ungaze ungathandabuzi ukuthetha nogqirha wakho ngalo.
