Isugeynta maskaxda, oo magaceeda ugu saxsan uu yahay cerebral perfusion tomography scintigraphy (SPECT), waa baaritaan la sameeyo si loo ogaado isbeddelada wareegga dhiigga iyo shaqada maskaxda, waxaana badanaa loo sameeyaa si looga caawiyo aqoonsiga ama kormeerka cudurrada maskaxda ee xumaada, sida Alzheimers, Parkinson's ama buro, gaar ahaan marka baaritaanada kale sida MRI ama CT scan kuma filna inay xaqiijiyaan tuhunada jira.

Imtixaanka scintigraphy ee maskaxda ayaa lagu sameeyaa cirbadeynta daawooyinka loo yaqaan 'radiopharmaceuticals or radiotracers', kuwaas oo awood u leh inay isku hagaajiyaan unugyada maskaxda, iyagoo u oggolaanaya sameynta sawirro aaladda.

Scintigraphy waxaa sameeya dhakhtarka, waxaana lagu sameyn karaa isbitaalada ama rugaha caafimaad ee sameeya baaritaanka daawada nukliyeerka, iyadoo la adeegsanayo codsi caafimaad oo macquul ah, iyada oo loo marayo SUS, heshiisyada qaar, ama qaab gaar ah.

Maxaa loogu talagalay

Sawir-qaadidda maskaxda ayaa bixisa macluumaad ku saabsan dhiig-baxa dhiigga iyo shaqada maskaxda, oo aad waxtar ugu leh xaaladaha sida:

• Raadi waallida, sida cudurka 'Alzheimer' ama 'dypiacle dypia';
• Aqoonso diiradda suuxdinta;
• Qiimee burooyinka maskaxda;
• Caawinta baaritaanka cudurka Parkinson ama cilladaha kale ee cudurka Parkinsonian, sida cudurka Huntington;
• Qiimaynta cudurada maskaxda ku dhaca sida shisoofrani iyo niyad jab;
• Samee baaritaan hore, xakameyn iyo isbeddel ku yimaada cudurrada maskaxda ee xididdada dhiigga sida istaroogga iyo noocyada kale ee istaroogga;
• Xaqiiji dhimashada maskaxda;
• Qiimeynta dhaawaca naxdinta leh, hematomada subdural, maqaarka iyo kiisaska cilladaha xididdada dhiigga;
• Qiimeynta nabar bararsan, sida herpesic encephalitis, systemic lupus erythematosus, cudurka Behçet iyo encephalopathy oo laxiriira HIV.

Badanaa, scintigraphy maskaxda ayaa la codsadaa marka ay jiraan shakiyo ku saabsan ogaanshaha cudurka neerfaha, tan iyo baaritaanada sida magnetic resonance iyo tirooyinka xisaabinta, maadaama ay muujinayaan isbeddelo badan oo qaabdhismeed iyo anatomy ee unugyada maskaxda ah, kuma filna in lagu caddeeyo xaaladaha qaarkood. .

Sidee loo sameeyaa

Si loo sameeyo scintigraphy-ka maskaxda, diyaar garow gaar ah looma baahna. Maalinta baaritaanka, waxaa lagula talinayaa in bukaanku nasto illaa 15 illaa 30 daqiiqo, qol deggan, si loo yareeyo welwelka, si loo hubiyo in tayada imtixaanku ka wanaagsan tahay.

Kadib, daawada radiopharmaceutical, badanaa Technetium-99m ama Thallium, ayaa lagu dabaqayaa xididka bukaanka, oo ay tahay inuu sugo ugu yaraan 1 saac ilaa walaxda si sax ah maskaxda ugu urursan tahay kahor inta aan sawirada laga qaadin aaladda ilaa 40 ilaa 60 daqiiqo. . Inta lagu jiro muddadan, waxaa lagama maarmaan ah in la sii wado dhaqdhaqaaq la'aan iyo jiif, maxaa yeelay dhaqdhaqaaqa ayaa wax u dhimi kara sameynta sawirrada.

Kadibna bukaanku waxaa loo siidaayaa howlo caadi ah. Daawooyinka loo yaqaan 'radiopharmaceuticals' ee la isticmaalay badanaa ma keenaan falcelin ama waxyeello caafimaadka qofka baaritaanka sameeya.

Yaan yeelin

Scrinigraphy-ka maskaxda ayaa laga mamnuucay haweenka uurka leh ama naas nuujinaya, waana in lagu wargaliyaa iyadoo ay jiraan wax shaki ah.
