Dokotala wanu mwina anakulangizani kuti muyesedwe ndi PET scan. Anthu ena amaopa pang'ono mawu oti 'scan' akamanena zimenezo. Koma si chinthu choopa kwenikweni. Uwu ndi ukadaulo wapamwamba kwambiri womwe umatithandiza kuona zomwe zikuchitika m'thupi mwathu komanso momwe matenda akupitira patsogolo. Tiyeni tikambirane za zomwe zikuchitika, momwe zimachitikira, komanso ngati tiyenera kuziopa.
Kodi PET scan imagwira ntchito bwanji kwenikweni?
Mwachidule, PET scan ndi mayeso apadera omwe amayang'ana momwe ziwalo ndi minofu ya thupi lathu ikugwirira ntchito. Ndi yosiyana ndi X-ray, CT kapena MRI scan, chifukwa ma scan ena amangowonetsa zithunzi za mkati mwa thupi. Komabe, PET scan imatha kuwonanso momwe maselo athu akugwirira ntchito. Asanachite mayesowa, dokotala adzalowetsa
mankhwala owopsa (otchedwa `radiotracer` kapena `tracer`) m'thupi lanu. Izi zili ngati mankhwala apadera. Musachite mantha, sizingavulaze thupi. Kenako makina owunikira a PET amatha kudziwa momwe mankhwalawa amayendera thupi ndi komwe amasonkhana. Ngati mankhwalawa asonkhana pamalo enaake, akhoza kukhala chizindikiro cha matenda. Ganizirani makina owunikira a PET awa ngati donut yayikulu. Bedi limasuntha pakati pake. Mumatumizidwa kukajambula muli pabedi. Makina awa sali otsekedwa kwathunthu ngati makina a MRI, kotero anthu ambiri samva ngati ali mumsampha.
Kodi kugwiritsa ntchito PET scan ndi kotani?
Madokotala amagwiritsa ntchito PET scan makamaka kuti adziwe matenda, kukonzekera opaleshoni, ndikuwona momwe chithandizo chikugwirira ntchito. Chimagwiritsidwa ntchito kwambiri pa khansa, matenda a mtima, ndi matenda a ubongo.
Za Khansa
Maselo a thupi lathu amafunika mphamvu kuti agwire ntchito. Maselo a khansa ndi mtundu wa selo lomwe limagwiritsa ntchito mphamvu zambiri kuposa maselo wamba. Kujambula kwa PET kumatha kuzindikira kugwiritsa ntchito mphamvu zambiri kumeneku. Kenako, pachithunzi cha kujambulidwa, madera omwe maselo a khansa amaoneka
ngati mawanga owala . Kujambula kwa PET nthawi zambiri kumatha kuzindikira khansa mayeso ena asanathe. Komanso,
- Onani ngati khansa yafalikira ku ziwalo zina za thupi.
- Dziwani ngati chithandizo chomwe chikugwiritsidwa ntchito panopa chili chothandiza.
- Yang'anani ngati khansa yabwerera mutalandira chithandizo.
Matenda a Mtima
Kujambula kwa PET kungasonyeze momwe mtima wanu ukugwira ntchito. Pamene 'tracer' yomwe yatchulidwayi yalowetsedwa m'thupi lanu, imapita kumtima kwanu ndi magazi anu. Kujambulaku kumasonyeza kuchuluka kwa magazi omwe akulowa m'malo osiyanasiyana a mtima wanu. Ngati gawo lina silikupeza magazi okwanira, likhoza kusonyeza vuto, monga kutsekeka kwa mtsempha wa mtima. Kumagwiritsidwanso ntchito poyang'ana kuwonongeka kwa mtima pambuyo pa matenda a mtima.
Za Matenda a Ubongo
Kujambula kwa PET kungathandizenso kuzindikira matenda osiyanasiyana okhudzana ndi ubongo. Mwachitsanzo:
Kodi kusiyana pakati pa PET, CT, ndi MRI scans ndi kotani?
Pali chisokonezo chachikulu pakati pa anthu pa mitundu itatu iyi ya ma scan. Tiyeni timvetse kusiyana kumeneku ndi tebulo.
| Mtundu wa sikani | Momwe imagwirira ntchito | Kodi chikusonyeza chiyani? |
|---|
| Kujambula kwa PET | Ntchito ya maselo imayesedwa pogwiritsa ntchito mankhwala otulutsa ma radioactive (tracer). | Imasonyeza momwe ziwalo ndi minofu zimagwirira ntchito . Ntchito ya maselo odwala ikhoza kuzindikirika. |
| Kujambula kwa CT | Ma X-ray amagwiritsidwa ntchito kujambula zithunzi za thupi lonse. | Imasonyeza kapangidwe ndi mawonekedwe a mafupa, mitsempha yamagazi, ndi minofu yofewa. |
| Kujambula kwa MRI | Zithunzi zimajambulidwa pogwiritsa ntchito maginito amphamvu komanso mafunde a wailesi. | Imasonyeza kapangidwe komveka bwino komanso katsatanetsatane ka zinthu monga ziwalo, minofu, ndi msana. |
Mwachidule, CT ndi MRIZili ngati kujambula 'chithunzi' cha mkati mwa thupi. Koma kujambula PET kuli ngati kujambula kanema wa momwe chiwalocho 'chimagwirira ntchito'.
Pachifukwa ichi, madokotala ena amagwiritsa ntchito ma scan osakanikirana otchedwa PET/CT kapena PET/MRI. Ma scan amenewa amatha kuwona kapangidwe ndi ntchito ya thupi pojambula kamodzi, kotero zotsatira zake zimakhala zolondola kwambiri.
Kodi mumakonzekera bwanji musanajambule?
Pali zinthu zingapo zomwe muyenera kukonzekera musanachite PET scan. Kutsatira njira izi ndikofunikira kwambiri kuti mupeze zotsatira zolondola.
Choyamba, uzani dokotala wanu zinthu izi:
- Ziwengo : Onetsetsani kuti mwatiuza ngati muli ndi ziwengo zilizonse, makamaka utoto wosiyana, ayodini , kapena nsomba.
- Matenda ena: Ngati muli ndi matenda monga matenda a shuga , chonde tidziwitseni za matendawa.
- Mankhwala omwe mumamwa: Uzani dokotala wanu za mankhwala onse, mavitamini, ndi mankhwala azitsamba omwe mumamwa.
Ngati ndinu mkazi, samalani kwambiri ndi izi:
- Ngati ndinu mayi woyamwitsa: Simungathe kuyamwitsa mwana wanu mpaka chotsukiracho chitatuluka m'thupi lanu. Chifukwa chake, muyenera kutulutsa mkaka wanu ndikuwuchotsa. Lankhulani ndi dokotala wanu kuti mudziwe nthawi yeniyeni yomwe muyenera kupewa kuyamwitsa.
- Ngati muli ndi pakati kapena mukuganiza kuti muli ndi pakati: Izi ndizofunikira kwambiri . Zinthu zowononga zomwe zimagwiritsidwa ntchito mu scan zitha kuvulaza mwana. Choncho uzani dokotala wanu za izi ndikukambirana za njira yabwino kwambiri.
Zinthu zofunika kutsatira tsiku lisanafike scan:
- Musachite masewera olimbitsa thupi otopetsa kwa maola 24 mayeso asanachitike.
- Musadye kapena kumwa china chilichonse kupatula madzi kwa maola angapo musanayesedwe.
- Chotsani zodzikongoletsera zonse zachitsulo m'thupi lanu, monga ndolo, mikanda, ndi mphete.
Momwe PET scan imachitikira
Ngakhale pali kusiyana pang'ono kutengera komwe kukuchitika komanso chifukwa chake kujambulidwaku, nthawi zambiri kumakhala motere: 1. Mudzafunsidwa kuvala diresi la kuchipatala. 2. Mudzapatsidwa mwayi wopita kuchimbudzi musanajambulidwe. 3. Kenako chojambulira chidzalowetsedwa m'thupi lanu. Izi zitha kuperekedwa ngati jakisoni, ngati piritsi, kapena ngati mpweya womwe mumapuma. 4. Muyenera kudikira
mphindi 30 mpaka 60 kuti chojambuliracho chilowe m'thupi lanu lonse. 5. Kenako mudzagona pabedi la chojambulira.
Musasunthe kapena kulankhula mukamajambula.Muyenera kukhala chete kwambiri. Izi zingatenge mphindi 30-60. Mungamve phokoso la kulira ndi kudina kuchokera ku makina pamene scan ikuchitidwa. Iyi ndi mayeso osapweteka. Komabe, anthu ena amatha kumva ululu m'thupi lawo ngati akhala pamalo omwewo kwa nthawi yayitali.
Mukamaliza kusanthula, imwani madzi ambiri kuti muthandize chotsukira kutuluka m'thupi lanu mwachangu. Komanso, popeza thupi lanu lidzakhala ndi mphamvu yochepa ya radioactivity kwa maola angapo, dokotalayo amalangiza amayi apakati, ana aang'ono, ndi makanda kuti asamayandikirane kwambiri panthawiyo.
Kodi pali zoopsa kapena zotsatirapo zake?
Kujambula PET nthawi zambiri kumakhala kotetezeka kwambiri, koma pali zoopsa zina ndi zovuta zina.
- Anthu omwe ali ndi vuto la claustrophobia (kuopa malo otsekedwa) angavutike kukhala mkati mwa makina. Komabe, dokotala wanu angakupatseni mankhwala kuti akupatseni bata panthawi ngati zimenezi.
- Ngati munthu wodwala matenda a shuga sakulamulira kuchuluka kwa shuga m'magazi mwake, zotsatira za mayesowo zingakhale zolondola.
- Pakhoza kukhala kupweteka kapena kufiira pamene chotsukiracho chinabayidwa.
- Kawirikawiri, ziwengo zimatha kuchitika ku tracer, koma nthawi zambiri zimakhala zochepa.
- Apanso, PET scan sidzachitika kwa mayi woyembekezera kapena woyamwitsa.
Tiyeni tidziwe za zotsatira zake.
Zotsatira za PET scan zikabweranso, malo omwe maselo ambiri amagwira ntchito amaoneka ngati mawanga owala. Izi zitha kukhala chizindikiro cha matenda.
Komabe, ndikofunikira kudziwa kuti zotsatira zabwino pa PET scan sizitanthauza kuti pali khansa nthawi zonse. Zingakhalenso matenda, kutupa, kapena chotupa chosakhala khansa. Komanso, ngati mwangochitidwa opaleshoni, chemotherapy, kapena radiation, zomwe zingakhudze zotsatira zake. Chifukwa chake, musakhale ndi nkhawa kwambiri kuti mupeze chithunzi chonse cha zomwe zotsatira zake zikutanthauza mukalandira. Dokotala wanu adzayerekeza zotsatira ndi malipoti ena a mayeso, adzayitanitsa mayeso ena ngati pakufunika kutero, ndikukufotokozerani zonse.
Uthenga Wopita Nawo Kunyumba
- Kujambula kwa PET sikungoyang'ana ziwalo za thupi zokha, komanso momwe zikugwirira ntchito . Izi ndizofunikira kwambiri pozindikira khansa, matenda a mtima, ndi matenda a ubongo.
- Kawirikawiri mayeso amenewa ndi otetezeka, koma onetsetsani kuti mwauza dokotala wanu ngati muli ndi pakati, mukuyamwitsa, muli ndi matenda a shuga, kapena muli ndi ziwengo zina .
- Tsatirani malangizo omwe aperekedwa musanayesedwe bwino (monga kusala kudya komanso kusachita masewera olimbitsa thupi).
- Kungoti malo owala aonekera pa scan sikutanthauza kuti ndi khansa nthawi zonse. Musadandaule nazo, lankhulani ndi dokotala wanu kuti akupatseni chidziwitso choyenera.
- Mukamaliza kuyezetsa, imwani madzi ambiri ndikutsatira malangizo a dokotala.
