Xa ugqirha wakho ekuxelela ukuba kufuneka wenze i-'Nuclear Medicine Scan', usenokuba noloyiko okanye unomdla. Xa sisiva igama elithi 'nuclear', kuvela izinto ezahlukeneyo engqondweni. Kodwa oku akuyonto ibalulekileyo yokoyika. Olu luvavanyo lwezonyango olubaluleke kakhulu nolukhuselekileyo olunceda ekufumaneni izifo ezininzi kwangethuba. Masibone ukuba yintoni, yenziwa njani, kwaye zeziphi izinto ezilungileyo nezingalunganga. Masithethe ngayo yonke into ngokulula.
Yintoni i-Nuclear Medicine Imaging ngamazwi alula?
Ngamafutshane, le yindlela ekhethekileyo yokuskena esetyenziselwa ukujonga amalungu angaphakathi emizimbeni yethu. Kodwa into ekhethekileyo ngale nto kukuba ayinakubona kuphela imilo yesitho, kodwa nendlela esebenza kakuhle ngayo .
Nantsi indlela yokwenza oku:
1. Okokuqala, uza kunikwa isixa esincinci kakhulu sento enemisebe (iRadioactive Tracer). Oku kudla ngokwenziwa ngemithambo yegazi. Ngamanye amaxesha unganikwa nesiselo.
2. Le 'tracer' ayisiyoyeza okanye idayi. Ngoko ke akukho miphumo mibi . Ifana nepasela. Xa ingena emzimbeni, iya ngqo kwilungu esifuna ukulibona (umzekelo, intliziyo, izintso, i-thyroid gland).
3. Umlinganiselo omncinci wamandla (imitha) uphuma kwi-'tracer' engene kuloo malungu. Asiyiva loo nto.
4. Emva koko ufakwa kumatshini wokuskena onekhamera ekhethekileyo ebizwa ngokuba yi-'gamma camera'. Le khamera ithatha isignali evela kuloo nxalenye yomzimba ize isebenzise ikhompyutha ukwenza umfanekiso omhle nocacileyo welo lungu.
Ngokujonga le mifanekiso, ingcali inokubona ukuba amalungu akho omzimba asebenza kakuhle okanye ukuba kukho ingxaki.
Oku kwahluke njani kwiimvavanyo ezifana ne-X-ray kunye ne-CT scans?
Lo ngumbuzo abantu abaninzi abanawo. Nje ukuba uwuqonde umahluko ophambili phakathi kwezi mvavanyo zimbini, ukubaluleka konyango lwenyukliya kuya kucaca ngakumbi kuwe.
Cinga ngenjini yemoto yakho. Xa uvula ibhonethi yemoto uze ujonge injini, ungabona iindawo zayo. Yiyo loo nto isakhiwo (iAnatomy) . Yile nto eyenziwa zi-scan ezifana ne-X-ray, i-CT, i-MRI. Oko kukuthi, zijonga imo kunye nobukhulu besitho, nokuba kukho nantoni na kuso, njengethumba okanye ukwaphuka.
Ngoku khawucinge ngokuqalisa imoto uze umamele isandi senjini isebenza. Ngale ndlela sinokuqonda ukuba injini isebenza kakuhle na okanye kukho isifo kwenye indawo. Nguwo lowo umsebenzi . Yile nto eyenziwa yi-scan ye-nuclear medicine. Oko kukuthi, ijonga indlela esebenza kakuhle ngayo i-organ.
| Uphawu | Iskeni seMithi yeNyukliya | I-X-reyi / i-CT scan |
|---|---|---|
| Ikakhulu ndijonga | Umsebenzi welungu - oko kukuthi, indlela elisebenza ngayo ilungu. | I-Anatomy - oko kukuthi, imilo kunye nobukhulu besitho. |
| Ubuchwepheshe | Ukuthwebula imitha (evela kwi-tracer) ephuma emzimbeni ngekhamera. | Umatshini uthumela imisebe yemitha emzimbeni aze athathe umfanekiso welinye icala. |
| Ulwazi olufunyenweyo | Ulwazi olufana nendlela intliziyo empompa ngayo igazi? Izintso zicoca igazi kakuhle kangakanani? | Ulwazi olufana nokuba ithambo laphukile? Ngaba kukho ithumba emaphashini? |
Ngenxa yokuba lo msebenzi unokubonwa, iskeni yamayeza enyukliya inokufumanisa ukungasebenzi kakuhle kwamalungu omzimba kwezinye izifo, nangaphambi kokuba imo yesitho itshintshe.
Kutheni kufuneka senze olu hlobo lovavanyo?
Iiskeni zamayeza enyukliya zisetyenziselwa ukuxilonga izifo ezininzi, ukujonga impumelelo yonyango, kwaye ngamanye amaxesha zide zinyangwe.
| Imeko/ilungu | Imizekelo yezinto ekufuneka uziqaphele |
|---|---|
| Isifo sentliziyo | Emva kokuhlaselwa yintliziyo, jonga ukuba izihlunu zentliziyo zonakele na, ukuba imithambo yegazi ehambisa igazi entliziyweni ivalekile na, nokuba intliziyo impompa igazi kakuhle kangakanani na. |
| Iingxaki zamathambo | Khangela ukwaphuka okuncinci, usulelo, kunye neeseli zomhlaza ezisenokungabonakali kwi-X-ray. |
| Isifo se-thyroid | Ukuze ufumane ngokuchanekileyo ukuba i-thyroid gland isebenza kakhulu na (hyperthyroidism) okanye ayisebenzi ngokwaneleyo (hypothyroidism), jonga ukuba azikho na ii-nodules. |
| Isifo sezintso | Jonga ukuba izintso zihlambulula kakuhle kangakanani na igazi, nokuba kukho naziphi na izithintelo ekuphumeni komchamo, nokuba kukho naziphi na izibazi ezibangelwa zizifo. |
| Umhlaza | Ukufumanisa ukuba umhlaza usasazeke na kwamanye amalungu omzimba (i-metastasis) nokubona ukuba unyango luphumelele kangakanani. I-PET scan ikwaluhlobo olukhethekileyo lwe-scan. |
| Ezinye | Chonga amahlwili egazi emiphungeni, ukusebenza kwenyongo, ezinye zeengxaki zobuchopho, kunye nezifo zegazi. |
Ukongeza, obu buchwephesha bukwasetyenziselwa ukunyanga ezinye iintlobo zomhlaza. Bubizwa ngokuba yi-"Radioimmunotherapy." Kule nto, izinto ezisebenzisa i-radioactive zithunyelwa ngqo kwiiseli zomhlaza kwaye zitshatyalaliswe.
Ndingenza ntoni ngaphambi nangosuku lovavanyo?
Lo usenokuba ngumbuzo omkhulu engqondweni yakho, kodwa akukho mfuneko yokulungiselela kakhulu oku.
Ukulungiselela ngaphambi kovavanyo
Akukho mthetho uqhelekileyo woku. Indlela ekufuneka uzilungiselele ngayo iya kwahluka ngokuxhomekeke kuhlobo lweskeni onayo .
- Kwezinye iiskeni, ungacelwa ukuba ungatyi okanye ungaseli nantoni na ngaphandle kwamanzi kangangeeyure ezi-6 ngaphambi kovavanyo.
- Ezinye iiskeni zisenokungabi namiqathango yokutya okanye yokusela.
- Eyona nto ibalulekileyo onokuyenza ngeli xesha kukuhlala uzolile kwaye uzolile . Njengaxa uthatha ifoto, ukuba uyashukuma, umfanekiso usenokuba mfiliba.
- Ukuskena kudla ngokuthatha malunga nemizuzu engama-30-60.
- Ngamanye amaxesha kukho amaxesha apho imifanekiso ithathwa ngaphezu kwemini enye, kwiintsuku ezininzi.
- Umlinganiselo wemitha: Ubungakanani bemitha efunyanwa ngumzimba wakho ngexesha lovavanyo luphantsi kakhulu. Lusenokuba ngaphantsi kunalo oluvela kwi-CT scan. I-tracer ishiya umzimba kwiiyure okanye iintsuku ezimbalwa.
- Ii-Allergy: Umngcipheko wokuba ne-allergy kwi-tracer uphantsi kakhulu. Nangona kunjalo, ukuba kukho nayiphi na i-allergy kuyo nayiphi na into, kubalulekile ukuxelela ugqirha wakho kwangaphambili.
- Akukho ntlungu: Oku akubuhlungu njengotyando. Akukho ntlungu ngaphandle kokufakwa kwenaliti encinci.
- Ukufunyaniswa kwezifo kwangethuba: Njengoko bekutshiwo ngaphambili, utshintsho ekusebenzeni kwesitho lunokufunyaniswa kwangethuba, nto leyo evumela ukuba isifo sibonwe ngaphambi kokuba sibe sibi kakhulu.
- Ulwazi oluchanekileyo: Ungafumana ulwazi oluchanekileyo noluneenkcukacha olungenakufunyanwa kwezinye iimvavanyo.
- Ukuthintela utyando olungeyomfuneko: Ngamanye amaxesha utyando lokuhlola luyadingeka ukuze kufunyanwe isifo. Kodwa iskeni efana nale inokuphelisa loo mfuneko.
- Musa ukoyika igama elithi 'nuclear'. Ubungakanani be-radioactive tracer esetyenzisiweyo apha buncinci kakhulu, kwaye bukhuselekile.
- Olu vavanyo alujongi imilo yesitho sakho somzimba, kodwa lujonga 'umsebenzi' waso. Oku kuvumela ukubonwa kwesifo kwangethuba.
- Olu ayilovavanyo lubuhlungu. Okufuneka ukwenze kukulala ungashukumi phantsi kwesikena.
- Cela ugqirha wakho okanye isibhedlele ukuba akunike imiyalelo ethile malunga nento omawuyenze ngaphambi kovavanyo. Ayizizo zonke iiskeni ezifuna ukulungiswa okufanayo.
- Ugqirha wakho uza kukuchazela iziphumo. Ungathandabuzi ukubuza nayiphi na imibuzo okanye iinkxalabo onokuba nazo ngelo xesha.
Kungoko ke, kungcono ukufumana imiyalelo ecacileyo malunga noku kugqirha wakho okanye kwisibhedlele/kwiziko lokuskena apho uvavanyo lwenziwa khona. Landela kanye oko bakutshoyo.
Kwenzeka ntoni ngexesha lovavanyo?
Uza kufakwa inaliti yetracer uze ucelwe ukuba ulinde ixesha elithile ukuze ingene kwisitho somzimba. Eli xesha liyahluka ukusuka kwiskeni ukuya kwiskeni. Kungathatha imizuzu embalwa. Kwinto efana neskeni yamathambo, kungathatha iiyure ezi-2-3.
Emva koko uza kusiwa kwigumbi lokuskena uze ulaliswe kwindawo efana nebhedi yomatshini. Ikhamera ye-gamma iza kubekwa phezu kwenxalenye efanelekileyo yomzimba wakho kwaye iqalise ukuthatha imifanekiso.
Ngaba kukho iingozi koku? Zithini iingenelo?
Kuqhelekile ukuba uzive usoyika xa usiva igama elithi 'radioactive', kodwa umngcipheko uphantsi kakhulu.
Kukho iingenelo ezininzi kolu vavanyo:
Emva kovavanyo
Ngokwesiqhelo, ungaqhubeka nemisebenzi yakho yesiqhelo emva kokuskena. Akukho miqathango kwizinto ozityayo okanye oziselayo. Ugqirha wakho uya kukucebisa ukuba usele amanzi amaninzi imini yonke. Oku kuya kunceda i-tracer eseleyo emzimbeni wakho ukuba ikhutshwe ngokukhawuleza ngomchamo wakho.
Iiskeni zakho ziya kuhlolwa yingcali kwaye kuya kulungiswa ingxelo. Nje ukuba ingxelo ifunyenwe ngugqirha wakho onyangayo, uya kukufowunela aze akuchazele iziphumo.
