Brain PET scan

Tsarin kwakwalwa mai kwakwalwa (PET) shine gwajin hoto na kwakwalwa. Yana amfani da sinadarin rediyo mai suna tracer don neman cuta ko rauni a cikin kwakwalwa.

Wani hoton PET ya nuna yadda kwakwalwa da kyallen takarda ke aiki. Sauran gwaje-gwajen daukar hoto, kamar su maganadisu mai daukar hankali (MRI) da sikanin kirji (CT) kawai yana bayyana tsarin kwakwalwa ne.

Sanarwar PET tana buƙatar ƙananan adadin kayan aikin rediyo (tracer). Ana ba da wannan mai silar ne ta wata jijiya (IV), galibi a cikin gwiwar gwiwar ka. Ko kuma, kuna numfasawa a cikin kayan aikin rediyo azaman gas.

Mai siye-tafiye yana tafiya ta jininka kuma yana tattara cikin gabobi da kayan aiki. Traan wasan yana taimaka wa mai ba da lafiyar ku don ganin wasu yankuna ko cututtuka da kyau.

Kuna jira a kusa yayin da mai binciken ya mamaye jikin ku. Wannan yakan dauki kusan awa 1.

Bayan haka, za ku kwanta a kan kunkuntar tebur, wanda ya zame cikin babban na'urar daukar hotan takardu mai siffar rami. Kayan aikin PET yana gano sigina daga mai siye. Kwamfuta tana canza sakamakon zuwa hotuna 3-D. Ana nuna hotunan akan mai sakawa don mai ba da sabis ya karanta.

Dole ne kuyi kwance har yanzu yayin gwajin domin inji zai iya samar da cikakkun hotunan kwakwalwar ku. Ana iya tambayarka ka karanta ko ka rubuta sunayen haruffa idan ana gwada kwakwalwarka.

Gwajin yana ɗaukar tsakanin minti 30 da awanni 2.

Ana iya tambayarka kada ka ci komai na tsawon awanni 4 zuwa 6 kafin binciken. Za ku iya shan ruwa.

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).
• Kun sha insulin don ciwon suga. Kuna buƙatar shiri na musamman.

Koyaushe fadawa mai baka game da magungunan da kake sha, gami da waɗanda aka siya ba tare da takardar sayan magani ba. Wani lokaci, magunguna suna tsoma baki tare da sakamakon gwajin.

Kuna iya jin ƙaiƙayi mai kaifi lokacin da aka sanya allurar da ke ƙunshe da abin da aka gano 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.

Bayan gwajin, sha ruwa mai yawa don fitar da abin da aka samo daga jikin ku.

A PET scan zai iya nuna girman, sura, da aikin kwakwalwa, don haka likitan ku na iya tabbatar yana aiki kamar yadda ya kamata. Ana amfani dashi mafi yawa lokacin da wasu gwaje-gwaje, kamar su MRI scan ko CT scan, basu samar da cikakken bayani ba.

Ana iya amfani da wannan gwajin don:

• Gano cutar kansa
• Shirya tiyata
• Taimaka wajan gano cutar dementia idan sauran gwaje-gwaje da gwaje-gwaje basu samar da cikakken bayani ba
• Faɗi bambanci tsakanin cutar Parkinson da sauran rikicewar motsi

Za'a iya ɗaukar sikanin PET da yawa don sanin yadda kuke amsa maganin cutar kansa ko wata cuta.

Babu wasu matsaloli da aka gano a cikin girma, sura, ko aikin kwakwalwa. Babu wuraren da mai sihiri ya tara su yadda yakamata.

Sakamakon sakamako mara kyau na iya zama saboda:

• Alzheimer cuta ko lalata
• Ciwon ƙwaƙwalwa ko yaduwar cutar daji daga wani yankin jiki zuwa kwakwalwa
• Cutar farfadiya, kuma yana iya gano inda ciwon ya fara a kwakwalwarka
• Rikicin motsi (kamar cutar Parkinson)

Adadin radiation da akayi amfani dashi a cikin PET scan yana da ƙasa. Kusan adadin adadin radiation kamar yadda yake a yawancin sikanin CT. Hakanan, radiation din baya dadewa a jikinka.

Mata masu juna biyu ko masu shayarwa ya kamata su sanar da mai ba su kafin su yi wannan gwajin. Jarirai da jarirai masu tasowa a cikin mahaifar sun fi lura da tasirin radiation saboda har yanzu gabobin su na girma.

Abu ne mai yiyuwa, kodayake ba mai yiwuwa bane, don samun rashin lafiyan abu mai tasirin rediyo. 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.

Ana iya yin sikanin PET tare da hoton CT. Wannan hoton na hade shi ake kira PET / CT.
