Kupopera kwa PET

Positron emission tomography (PET) ndi njira yotsogola yolingalira zamankhwala. Imagwiritsa ntchito tracer yama radioactive kuti izindikire kusiyanasiyana kwamatenda pamaselo. Kusanthula thupi lonse kwa PET kumatha kuzindikira kusiyanasiyana kwa magwiridwe antchito amthupi, monga kuyenda kwa magazi, kugwiritsa ntchito mpweya, komanso kutenga mamolekyulu a shuga (shuga). Izi zimathandiza dokotala kuti awone momwe ziwalo zina zimagwirira ntchito.

Pazovuta zam'mapapo, adotolo amatha kuyang'anitsitsa m'mapapo kwinaku akumasulira zithunzi za PET.

Pulogalamu ya m'mapapo ya PET imagwirizanitsidwa ndi mapapu a CT kuti muwone ngati khansa ya m'mapapo. Kompyutayi imaphatikiza chidziwitso kuchokera pazithunzi ziwiri kuti chikhale chithunzi chazithunzi zitatu, chomwe chikuwunikira magawo aliwonse azomwe zimachitika mwachangu. Izi zimadziwika kuti kusakanikirana kwazithunzi. Zojambulazo zimalola dokotala wanu kusiyanitsa pakati pa anthu oopsa (osayambitsa khansa) ndi oopsa (khansa).

Kodi kusaka kwa PET kwamapapu kumachitika bwanji?

Pofufuza m'mapapo a PET, umalowetsedwa kudzera m'mitsempha yocheperako shuga yomwe imakhala ndi mankhwala osokoneza bongo pafupifupi ola limodzi chisanafike. Nthawi zambiri, isotope ya element fluorine imagwiritsidwa ntchito. Singanoyo imatha kuluma kwakanthawi, koma apo ayi njirayi siyopweteka.

Kamodzi m'magazi, chinthucho chimasonkhana m'ziwalo zanu ndi matupi anu ndikuyamba kupereka mphamvu ngati cheza cha gamma. Chojambulira cha PET chimazindikira kunyezimira uku ndikupanga zithunzi mwatsatanetsatane kuchokera kwa iwo. Zithunzizi zitha kuthandiza dokotala kuti awunikire kapangidwe kake ndi kagwiritsidwe ntchito ka chiwalo kapena dera lomwe likuwunikiridwa.

Pakati pa mayeso, muyenera kukhala pansi patebulo locheperako. Tebulo ili limalowa mkati mwa sikani yoboola pakati. Mukutha kulankhula ndi akatswiri pamene kusanthula kukuchitika, koma ndikofunikira kugona chete pomwe sikani ikuyenda. Kuyenda kwambiri kumatha kubweretsa zithunzi zosalongosoka.

Kuwunika kumatenga pafupifupi mphindi 20 mpaka 30.

Momwe mungakonzekerere

Dokotala wanu adzakufunsani kuti musadye kapena kumwa chilichonse kupatula madzi kwa maola angapo musanayese. Ndikofunika kwambiri kutsatira malangizo awa. Kusanthula PET nthawi zambiri kumadalira pakuwunika kusiyanasiyana pang'ono m'momwe maselo amathandizira shuga. Kudya chotupitsa kapena kumwa chakumwa chotsekemera kungasokoneze zotsatira.

Mukafika, mutha kupemphedwa kuti musinthe zovala zanu zachipatala, kapena mungaloledwe kuvala zovala zanu. Muyenera kuchotsa zinthu zilizonse zachitsulo mthupi lanu, kuphatikiza zibangili.

Uzani dokotala wanu ngati mukumwa mankhwala kapena zowonjezera. Mankhwala ena, monga omwe amachiza matenda ashuga, amatha kusokoneza zotsatira za PET scan.

Ngati simuli omasuka m'malo otsekedwa, dokotala wanu akhoza kukupatsani mankhwala kuti akuthandizeni kupumula. Mankhwalawa mwina amayambitsa kugona.

Pulogalamu ya PET imagwiritsa ntchito kanyumba kakang'ono ka radioactive. Ma radioacac tracer satha kugwira ntchito mthupi lanu mkati mwa maola ochepa kapena masiku ochepa. Pamapeto pake imatuluka mthupi lanu kudzera mumkodzo ndi chopondapo.

Ngakhale kutulutsa kwa radiation kuchokera ku PET scan sikokwanira, muyenera kudziwitsa dokotala musanachite chilichonse chogwiritsa ntchito radiation ngati muli ndi pakati kapena mukuyamwitsa.

Mapapu a PET ndikusanthula

Kujambula kwa m'mapapo kwa PET kumagwiritsidwanso ntchito popanga khansa yamapapo. Minofu yokhala ndi kagayidwe kachakudya (kugwiritsa ntchito mphamvu zambiri), monga zotupa za khansa yam'mapapo, zimayamwa zochulukirapo kuposa ziwalo zina. Madera awa amaonekera pa PET scan. Dokotala wanu amatha kugwiritsa ntchito zithunzi zazithunzi zitatu kuti azindikire zotupa za khansa zomwe zikukula.

Zotupa za khansa yolimba zimapatsidwa gawo pakati pa 0 ndi 4. Staging amatanthauza momwe khansa inayambira. Mwachitsanzo, khansa ya khansa 4 yapita patsogolo kwambiri, yafalikira patali, ndipo nthawi zambiri imakhala yovuta kuchiza kuposa khansa ya siteji 0 kapena 1.

Staging imagwiritsidwanso ntchito kulosera zamtsogolo. Mwachitsanzo, munthu amene amalandila chithandizo akapezeka kuti ali ndi khansa ya m'mapapo 0 kapena 1 amatha kukhala ndi moyo nthawi yayitali kuposa munthu yemwe ali ndi khansa ya 4.

Dokotala wanu amatha kugwiritsa ntchito zithunzi kuchokera m'mapapu a PET kuti adziwe njira yabwino yothandizira.
