PET scan

A positron emission tomography scan wani nau'in gwajin hoto ne. Yana amfani da sinadarin rediyo mai suna tracer don neman cuta a cikin jiki.

Sanarwar fitar da sinadarin positron (PET) ya nuna yadda gabobi da kyallen takarda ke aiki.

• Wannan ya bambanta da sikanin MRI da CT. Wadannan gwaje-gwajen suna nuna tsarin, da kuma gudanawar jini zuwa da daga gabobin.
• Ana amfani da injunan da ke haɗa hotunan PET da CT, waɗanda ake kira PET / CT.

Sanarwar PET tana amfani da ɗan ƙaramin abin bincike na rediyo. Ana bayar da sihirin ne ta wata jijiya (IV). Ana yawan sanya allurar a cikin gwiwar gwiwar ka. Mai siye-tafiye yana tafiya ta jininka kuma yana tattara cikin gabobi da kayan aiki. Wannan yana taimaka wa masanin kimiyyar rediyo ganin wasu yankuna sosai.

Kuna buƙatar jira kamar yadda jikin jikin ku yake bin tracer. Wannan yana ɗaukar awa 1.

Bayan haka, zaku kwanta akan kunkuntun teburin da yake zamewa cikin babban na'urar daukar hotan takardu mai siffar rami. PET tana gano sigina daga mai siye. Kwamfuta tana canza sigina zuwa hotuna 3D. Ana nuna hotunan akan mai sa ido don mai kula da lafiyar ku ya karanta.

Dole ne ku yi kwance har yanzu yayin gwajin. Yin motsi da yawa na iya ɓata hotuna da haifar da kurakurai.

Tsawon lokacin da gwajin zai ɗauka ya dogara da wane ɓangare na jikin da ake yin sikanin.

Ana iya tambayarka kada ka ci komai na tsawon awanni 4 zuwa 6 kafin binciken. Za ku iya shan ruwa amma ba sauran abubuwan sha tare da kofi. Idan kuna da ciwon sukari, mai ba ku sabis zai gaya muku kada ku sha maganin ciwon sukarinku kafin gwajin. Wadannan magunguna zasu tsoma baki tare da sakamakon.

Faɗa wa mai ba ka sabis idan:

• Kuna jin tsoron wuraren kusa (suna da claustrophobia). Za a iya ba ku magani don taimaka muku jin bacci da ƙarancin damuwa.
• Kuna da ciki ko kuma kuna tsammanin kuna da ciki.
• Kuna da duk wata cuta ga fenti mai launi (bambanci).

Koyaushe fadawa mai baka game da magungunan da kake sha. Bari mai ba da sabis ya san game da magungunan da kuka saya ba tare da takardar sayan magani ba. Wani lokaci, magunguna na iya tsoma baki tare da sakamakon gwajin.

Kuna iya jin zafi mai kaifi lokacin da aka sanya allurar tare da mai sifa a cikin jijiyar ku.

A PET scan ba ciwo. Tebur na iya zama mai wahala ko sanyi, amma zaka iya buƙatar bargo ko matashin kai.

Wata hanyar shiga cikin daki tana baka damar yin magana da wani a kowane lokaci.

Babu lokacin warkewa, sai dai idan an baka magani don shakatawa.

Abinda aka fi amfani dashi don hoton PET shine don cutar kansa, lokacin da za'a yi shi:

• Don ganin yadda cutar daji ta bazu. Wannan yana taimakawa wajen zaɓar mafi kyawun tsarin kulawa.
• Don bincika yadda cutar kansa take amsawa, yayin magani ko bayan an kammala jiyya.

Hakanan za'a iya amfani da wannan gwajin don:

• Duba aikin kwakwalwa
• Gano asalin farfadiya a cikin kwakwalwa
• Nuna wuraren da ƙarancin jini ke gudana zuwa zuciya
• Tabbatar idan taro a cikin huhunka yana da cutar kansa ko ba shi da illa

Sakamakon yau da kullun yana nufin babu matsalolin da aka gani a cikin girma, siffa, ko matsayin wani ɓangaren jikin. Babu wuraren da mai sihiri ya tara su yadda yakamata.

Sakamako mara kyau ya dogara da ɓangaren jikin da ake nazari. Sakamakon sakamako mara kyau na iya zama saboda:

• Ciwon daji
• Kamuwa da cuta
• Matsala tare da aikin gabobi

Adadin radiation da aka yi amfani da shi a cikin hoton PET ya yi daidai da adadin da aka yi amfani da shi a yawancin sikan CT. Waɗannan hotunan suna amfani da ɗan gajeren bincike, don haka radiation ɗin ya tafi daga jikinku cikin kimanin awanni 2 zuwa 10. Samun hotuna masu yawa, CT ko PET scans akan lokaci na iya ƙara haɗarin kamuwa da cutar kansa. Koyaya, haɗarin daga kowane sikan ɗaya karami ne. Ku da likitanku ya kamata ku auna wannan haɗarin akan fa'idodi na samun ingantaccen ganewar asali don matsalar likita.

Faɗa wa mai ba ka sabis kafin yin wannan gwajin idan kana da ciki ko kuma shayarwa. Jarirai da jariran da ke tasowa a mahaifar sun fi saurin daukar hankali saboda har yanzu gabobin su na girma.

Ba da daɗewa ba, mutane na iya yin rashin lafiyan abu zuwa kayan masarufin. Wasu mutane suna da ciwo, ja, ko kumburi a wurin allurar.

Zai yiwu a sami sakamako na ƙarya akan hoton PET. Sikarin jini ko matakan insulin na iya shafar sakamakon gwajin a cikin mutanen da ke da ciwon sukari.

Yawancin PET scans yanzu ana yinsu tare da CT scan. Wannan hoton na hade shi ake kira PET / CT. Wannan yana taimakawa wurin gano ainihin wurin da cutar.
