Uke wacelwa ukuthi wenze i-PET scan? Ake sixoxe ngalokhu ngokuningiliziwe!

Sawubona! Uma udokotela ekutshela nge-`(PET Scan)`, kungenzeka ukuthi uzizwe unelukuluku elincane, mhlawumbe wesaba kancane, akunjalo? Empeleni kuyinto evamile kakhulu. Ngoba akumangazi ukuzizwa ngaleyo ndlela uma ufunda ngento entsha. Ngakho-ke namuhla sizoxoxa ngokuthi iyini le `(PET Scan)`, ukuthi yenzani, ukuthi ungayilungiselela kanjani, kanye nakho konke okudingeka ukwazi ngendlela elula kakhulu, njengokukhuluma nomngane. Khona-ke uzokwazi ukuqonda kangcono lokhu.

Kuyini ukuskena kwe-PET?

Kalula nje, i-"PET Scan" ifushaniswa ne -Positron Emission Tomography scan . Lolu vivinyo olukhethekile olusetshenziselwa ukubona ukuthi izitho nezicubu ezingaphakathi kwemizimba yethu zisebenza kanjani. Cabanga ngakho njengokuthatha "isithombe esisebenzayo" sezinto ezingaphakathi kwemizimba yethu.

Kulolu vivinyo, sisebenzisa inani elincane kakhulu lamakhemikhali anemisebe aphephile . Lokhu sikubiza ngokuthi `(Radiotracer)`. Ngemva kokuthi lokhu kufakwe emzimbeni, izithombe zithathwa kusetshenziswa ikhamera ekhethekile, okuyi-`(PET Scanner)`. Ubuchwepheshe balo `(Radiotracer)` ukuthi uma kukhona amangqamuzana emzimbeni wethu anesifo esithile, lawo maseli amunca kakhulu lo `(Radiotracer)`. Njengoba nje umuntu olambile edla kakhulu lapho ebona ukudla. Ngakho-ke, isithwebuli singathola izindawo lapho lo `(Radiotracer)` umunca khona kakhulu. Yilokho okusiza odokotela bethu ukuthi babone ukuthi kukhona yini inkinga yezempilo.

Odokotela bavame ukusebenzisa le "(PET Scan)" ukuze bahlole umdlavuza futhi babone ukuthi ukwelashwa komdlavuza kusebenza kahle kangakanani. Akukhona lokho kuphela, futhi kuyasiza kakhulu ekuboneni ezinye izifo zenhliziyo nezinkinga ezihlobene nobuchopho.

Uyini umehluko phakathi kwe-PET scan, i-CT scan, kanye ne-MRI?

Kungenzeka ukuthi uke wezwa nge-scan ye-`(CT scan)` noma ye-`(MRI)`. Manje ake sibone ukuthi lokhu kuhluke kanjani kwi-`(PET Scan).`

• (I-CT Scan): Lokhu kusebenzisa ama-X-ray.
• (I-MRI Scan): Lokhu kusebenzisa omaginethi namagagasi omsakazo.

Kokubili ama-CT scan nama-MRI kusinika izithombe ezimile zezitho zomzimba nezakhiwo ezingaphakathi emizimbeni yethu. Okusho ukuthi, sibona kuphela ukuthi zibukeka kanjani ngaleso sikhathi.

Kodwa-ke, i-PET scan ihlukile kancane. Ngenxa yokuthi isebenzisa i-radiotracer esikhulume ngayo ngaphambilini, i-PET scan isibonisa ukuthi izitho zethu zisebenza kanjani ngesikhathi sangempela . Okusho ukuthi, kufana nokuzibuka ziphila. Enye into ebalulekile ukuthi i-PET scan ingabona izinguquko ezithweni nasezicutshini zethu ezingeni lamaseli ngokushesha kakhulu kunezinye i-CT ne-MRI scan.

Ngezinye izikhathi udokotela wakho angase ancome i-"PET Scan" kanye ne-"CT Scan" ngesikhathi esisodwa. Lokhu kubizwa ngokuthi i-"PET-CT scan". Uma lokhu kokubili kuhlanganiswa, sithola izithombe ezinezinhlangothi ezintathu (3D). Lokhu kusenza sikwazi ukuthola ukuxilongwa okunembile.

Ezinye izibhedlela manje zisebenzisa ubuchwepheshe obusha obubizwa ngokuthi i-"(PET/MRI)`` scan. Lokhu kungathatha izithombe ezicacile kakhulu nezisezingeni eliphezulu. Kusetshenziswa kakhulu ukuthola nokuqapha umdlavuza wezicubu ezithambile njengalowo wobuchopho, ikhanda nentamo, isibindi kanye ne-pelvis.

Yini ngempela ebhekwa yi-PET scan?

Udokotela wakho angase akucele ukuthi uhlolwe i-PET ukuze ahlole umzimba wakho nganoma yiziphi zalezi zimpawu:

• Umdlavuza: Izibonelo zifaka umdlavuza webele, umdlavuza wamaphaphu, kanye nomdlavuza we-thyroid.
• Isifo senhliziyo: Isifo semithambo yegazi ye-coronary, ukuhlaselwa yinhliziyo, noma ezinye izifo zenhliziyo.
• Izinkinga zobuchopho: Izimo ezifana nezimila zobuchopho, isifo sokuwa, i-dementia, kanye nesifo i-Alzheimer's.

Ngidinga nini ukuskena kwe-PET?

Ngokuvamile, ukuskena kwe-PET kungalinganisa imisebenzi ebalulekile emzimbeni wethu, njengokugeleza kwegazi, ukusetshenziswa komoya-mpilo, kanye nokusetshenziswa kukashukela egazini (i-glucose) . Kungasiza futhi ekuboneni izitho nezicubu ezingasebenzi kahle.

Uma kwenzeka umdlavuza:

Uma udokotela wakho esola ukuthi unomdlavuza, cishe bazoncoma ukuthi kwenziwe i-PET scan, njengoba lokhu kungasiza ekutholeni nasekuxilongeni umdlavuza.

Uma usuvele utholakale unomdlavuza, udokotela wakho angase akucele ukuthi uhlolwe i-PET ngaphezu kweyodwa ngesikhathi sokwelashwa kwakho. Kunezizathu eziningana zalokhu:

• Bheka ukuthi umdlavuza ususakazekele kwezinye izingxenye zomzimba (owakhiwe ngamaseli) .
• Hlola ukuthi ukwelashwa kwamanje kuphumelele kangakanani .
• Hlola ukuthi umdlavuza "ubuyile" yini ngemva kokwelashwa.
• Hlola ukubikezela komdlavuza.

Uma unesifo senhliziyo:

Uma unezinkinga zenhliziyo, udokotela wakho angase ancome ukuthi uhlolwe nge-PET ukuze ahlole izinto ezifana nalezi:

• Hlola ukuthi ngabe zikhona yini izingxenye zenhliziyo yakho ezithintekile ngenxa yokuhlaselwa yinhliziyo.
• Thola ukuthi yiziphi izingxenye zemisipha yenhliziyo ezingazuza ngokuhlinzwa kwe -angioplasty noma kwe-coronary artery bypass .

Uma unezimpawu zesimiso sezinzwa:

Uma unezimpawu ze-neurological, udokotela wakho angase ancome ukuthi kwenziwe i-PET scan ukuze kubhekwe izinkinga zobuchopho, njengezimila, isifo sokuwa, nezinye izimo zesimiso sezinzwa esiyinhloko.

Isebenza kanjani i-PET scan?

I-PET scan uhlobo lokuhlolwa olubizwa ngokuthi i-nuclear medicine imaging . I-nuclear medicine ihilela ukunikeza inani elincane kakhulu neliphephile lezinto ezinemisebe, njenge-radiotracers esixoxe ngazo ngaphambili, ngomjovo we-IV.

Okwenza ama-PET scan ahluke kwezinye izindlela zokuthwebula izithombe ukuthi agxila ezinqubweni nasemisebenzini yama-molecule eyenzeka emizimbeni yethu . Ngakho-ke, anamandla okuthola izifo zisesencane kakhulu.

Cabanga nje, uma unamaseli agulayo emzimbeni wakho, lawo maseli amunca okuningi kwe-`(Radiotracer)` kunamaseli anempilo. Sibiza lezi zindawo zokumuncwa okwandisiwe ngokuthi `(Hot Spots)` . `(PET Scanner)` ithola lo msebe futhi idale izithombe zezicubu ezithintekile. Njengoba sishilo ngaphambili, ku-`(PET/CT)` scan, izithombe ze-X-ray ezithathwe ku-`(CT scan)` kanye nezithombe ezithathwe ku-`(PET scan)` ziyahlanganiswa ukuze kunikezwe umphumela wokugcina.

Ngingakulungiselela kanjani ukuhlolwa kwe-PET?

Ukuskena kwe-PET kuyindlela yokulaliswa esibhedlela . Lokhu kusho ukuthi ungaya ekhaya ngosuku olufanayo nokuskena. Udokotela wakho uzokunikeza imiyalelo eningiliziwe yokuthi ungalungiselela kanjani ukuskena. Kodwa-ke, ngokuvamile kufanele uqaphele okulandelayo:

• Kubaluleke kakhulu ukunikeza udokotela wakho uhlu olunembile lwazo zonke izidakamizwa, amavithamini, izithasiselo, kanye nokungezwani komzimba okuthathayo .
• Uma ucabanga ukuthi ukhulelwe, noma uma ungumama oncelisayo , qiniseka ukuthi utshela udokotela wakho.
• Ungadli lutho amahora ayisithupha ngaphambi kokuhlolwa. Kodwa-ke, uma unesifo sikashukela , udokotela wakho angase ashintshe lesi seluleko. Ngakho khuluma nodokotela wakho ngakho.
• Ungaphuza amanzi kuphela .
• Uma uhlolwa inhliziyo, gwema ukuphuza noma yini equkethe i-caffeine (njengetiye noma ikhofi) amahora angama-24 ngaphambi kokuhlolwa.
• Gqoka izingubo ezikhululekile . Shiya ubucwebe bensimbi, izibuko, amazinyo okufakelwa, kanye nezikhonkwane zezinwele ekhaya.
• Uma uzizwa ungakhululekile noma ukhathazekile lapho usesikhaleni esivalekile , tshela udokotela wakho. Bangase bakunike umuthi wokudambisa omnene ukuze bakusize uphumule ngesikhathi sokuhlolwa.

Yini ongayilindela ngesikhathi sokuhlolwa kwe-PET?

Uma kwenziwa i-PET scan, izinto ezilandelayo zivame ukwenzeka:

• Okokuqala, uzonikezwa umjovo we-IV we-radioactive tracer. Kusetshenziswa inani eliphephile. I-radiotracer evame ukusetshenziswa kakhulu yi -Fluorodeoxyglucose (FDG) .
• Ngemuva kwalokho kufanele uhlale esihlalweni cishe ihora . Phakathi nalesi sikhathi, i-`(Radiotracer)` ihamba egazini lakho futhi imuncwa yizitho zakho nezicubu. Kubaluleke kakhulu ukuhlala unganyakazi phakathi nalesi sikhathi. Ngoba uma uhamba kakhulu, i-`(Radiotracer)` ingaya ezingxenyeni zomzimba wakho ezingahlolwa. Ngeke uyizwe i-`(Radiotracer)` ingena emzimbeni wakho.
• Uma uhlolwa nge-PET/CT scan, ungase unikezwe umjovo wodayi wokungafani . Lokhu kwenza izithombe ze-CT scan zicace kakhudlwana.
• Ngemuva kwalokho uzolaliswa etafuleni lokuhlola, bese uyiswa ku-PET/CT Scanner. Lesi sikena simise okwedonathi, sinomgodi phakathi. Lo mgodi ungamasentimitha angu-30 ububanzi.
• Kumelwe uhlale unganyakazi ngesikhathi sokuskena (okuthatha cishe imizuzu engama-30 ). Ukunyakaza kungabangela ukuthi izithombe zifiphale.
• Ungase uzwe umsindo wokubhonga noma wokuqhafaza njengoba iskena sithatha izithombe. Lokhu kuvamile.
• Ngaphambi kokuba uhambe, uchwepheshe uzobuyekeza ama-scan futhi aqinisekise ukuthi acacile.

Kuthatha isikhathi esingakanani ukuhlolwa kwe-PET?

Inqubo yonke yokuskena i-PET ingathatha cishe amahora amabili .

• Kuthatha cishe imizuzu engama-60 ukuthi umzimba wakho umunce i-``(Radiotracer)``. Phakathi nalesi sikhathi, kufanele uhlale uzolile futhi unganyakazi.
• I-``(PET Scan)'' yangempela ithatha cishe imizuzu engama-30 .
• Ngemuva kwalokho, kufanele ulinde isikhashana ngenkathi uchwepheshe ebuka izithombe futhi eqinisekisa ukuthi zicacile.

Ingabe kukhona izingozi noma imiphumela emibi kulokhu?

Ngokuvamile, ukuskena kwe-PET kuyindlela ephephile kakhulu yokuhlola , futhi izinkinga azivamile. Ukusebenza kwemisebe ku-radiotracer kuphansi kakhulu. Akuhlali isikhathi eside emzimbeni wakho. Kufanele uphuze amanzi amaningi ngemva kokuskena kwe-PET. Lokhu kuzosiza ukususa i-radioactive tracer emzimbeni wakho ngokushesha.

Ukuskena kwe-PET kungaba yingozi kuphela kulezi zimo ezikhethekile:

• Uma ukhulelwe noma uncelisa, akufanele wenze i-PET scan . Lokhu kungenxa yokuthi imisebe ingaba yingozi enganeni esibelethweni futhi ingadlulela enganeni ngobisi lwebele.
• Abanye abantu baba nokusabela kokungezwani komzimba ne-radiotracer ku-PET scan noma idayi yokungafani ku-CT scan.Kungenzeka. Kodwa lolu hlobo lokusabela aluvamile kakhulu futhi ngokuvamile luncane. Uma kwenzeka, ithimba lezokwelapha lingazelapha ngokushesha ngemithi.
• Abantu abanesifo sikashukela bangase bangakwazi ukumunca ushukela kahle ku-radiotracer. Lokhu kungathinta imiphumela yokuskena. Udokotela wakho uzokweluleka ngokuthi ungashintsha kanjani ukudla kwakho kanye nemithi ngaphambi kokuhlolwa.

Ngizoyithola nini imiphumela ye-PET scan?

Udokotela we-X-ray, oqeqeshwe ngokukhethekile ukufunda ama-PET scan, uzobuyekeza ama-scan akho, abhale umbiko, bese ewuthumela kudokotela wakho. Le nqubo ivame ukuthatha cishe amahora angama-24 .

I-PET scan iyisivivinyo esiwusizo kakhulu futhi esiphephile ngokuvamile esisetshenziswa odokotela ukuhlola umdlavuza, isifo senhliziyo, kanye nezimo zobuchopho.

Ngakho-ke, ekugcineni, izinto okufanele uzikhumbule...

Uma uceliwe ukuthi wenze i-PET scan, ungakhathazeki ngakho. Kuyindlela yokuhlola ephephile ezimweni eziningi futhi kungaba usizo kakhulu ekuxilongeni isifo.

Uma unemibuzo noma ukukhathazeka ngalolu vivinyo, ungangabazi ukubuza udokotela wakho noma umhlengikazi . Bakhona ukukusiza nokukunikeza ulwazi oludingayo. Bazophendula yonke imibuzo yakho. Ngakho-ke, phumula futhi ulandele imiyalelo kadokotela wakho.

` I-PET Scan, umdlavuza, isifo senhliziyo, isifo sobuchopho, i-X-ray, ukuhlolwa kwe-scan, ukuxilongwa
