Transcranial Doppler duban dan tayi

Transcranial doppler duban dan tayi (TCD) gwajin gwaji ne. Yana auna jini zuwa ciki da cikin kwakwalwa.

TCD yana amfani da raƙuman sauti don ƙirƙirar hotunan gudan jini a cikin kwakwalwa.

Wannan shine yadda ake yin gwajin:

• Za ku kwanta a bayanku a kan tebur mai ɗorawa tare da kai da wuyanku a matashin kai. Wuyanki ya dan miqe. Ko zaka iya zama akan kujera.
• Mai sana'ar yana amfani da gel ne mai ɗora ruwa a jikin gidajen ibada da fatar ido, ƙarƙashin muƙamuƙanka, da ƙasan wuyanka. Gel ɗin yana taimakawa raƙuman sauti su shiga cikin kyallen takarda.
• Ana motsa sanda, da ake kira transducer, akan yankin da ake gwada shi. Sandar tana aika sautin raƙuman ruwa. Sautin raƙuman ruwa ya ratsa jikin ku kuma ya tashi daga yankin da ake nazari (a wannan yanayin, kwakwalwar ku da jijiyoyin jini).
• Kwamfuta na kallon tsarin da igiyar sauti ke ƙirƙirawa yayin da suke dawowa. Yana haifar da hoto daga raƙuman sauti. Doppler yana kirkirar sauti "mai jujjuyawa", wanda shine sautin jininka yana motsawa ta jijiyoyi da jijiyoyin jini.
• Jarabawar na iya ɗaukar minti 30 zuwa awa 1 don kammalawa.

Ba a buƙatar shiri na musamman don wannan gwajin. Ba kwa buƙatar canzawa zuwa rigar likita.

Ka tuna da:

• Cire ruwan tabarau na tuntuɓar kafin gwajin idan ka sa su.
• Kashe idanunka yayin da aka sanya gel a kan idanunka don kar ka shiga cikin idanunka.

Gel din yana iya jin sanyi akan fata. Kuna iya jin ɗan matsi yayin da transducer ke motsawa a kusa da kai da wuya. Matsewar bazai haifar da wani ciwo ba. Hakanan zaka iya jin sautin "mara kyau". Wannan al'ada ce.

Ana yin gwajin ne don gano yanayin da ke shafar kwararar jini zuwa kwakwalwa:

• Ragewa ko toshewar jijiyoyin cikin kwakwalwa
• Bugun jini ko bugun iske na wucin gadi (TIA ko ministroke)
• Zub da jini a sararin samaniya tsakanin kwakwalwa da kyallen takarda da ke rufe kwakwalwa (zubar jini ta subarachnoid)
• Ballarar jijiyar jini a cikin kwakwalwa (cerebral aneurysm)
• Canji cikin matsi a cikin kwanyar (matsin intracranial)
• Ana fama da cutar sikila, don tantance haɗarin bugun jini

Wani rahoto na yau da kullun ya nuna yadda jini yake gudana zuwa kwakwalwa. Babu takaitawa ko toshewar jijiyoyin jini da ke kaiwa zuwa da cikin kwakwalwa.

Wani sakamako mara kyau yana nufin jijiyoyin na iya takaita ko wani abu yana canza saurin jini a jijiyoyin kwakwalwa.

Babu haɗari tare da samun wannan hanyar.
