Cerebral scintigraphy, eo lebitso la eona le nepahetseng ka ho fetesisa e leng cerebral perfusion tomography scintigraphy (SPECT), ke tlhatlhobo e etsoang ho bona phetoho ea phallo ea mali le ts'ebetso ea boko, mme hangata e etsoa ho thusa ho khetholla kapa ho beha leihlo mafu a holofatsang a boko joalo ka Alzheimer's, Parkinson kapa hlahala, haholo-holo ha liteko tse ling tse kang MRI kapa CT scan li sa lekana ho netefatsa lipelaelo.

Tlhatlhobo ea `` cerebral scintigraphy '' e etsoa ka ente ea lithethefatsi tse bitsoang li-radiopharmaceuticals kapa li-radiotracers, tse khonang ho itlhopha ka har'a lisele tsa boko, ho lumella ho theoa ha litšoantšo sesebedisweng.

Scintigraphy e etsoa ke ngaka, mme e ka etsoa lipetlele kapa litleliniking tse etsang litlhahlobo tsa meriana ea nyutlelie, ka kopo e loketseng ea bongaka, ka SUS, litumellano tse ling, kapa ka tsela ea lekunutu.

Cerebral scintigraphy e fana ka tlhaiso-leseling ka phallo ea mali le ts'ebetso ea boko, e thusang haholo maemong a kang:

• Batla 'dementias' tse kang Alzheimer's kapa Lewy corpuscle dementia;
• Khetholla sepheo sa sethoathoa;
• Lekola lihlahala tsa boko;
• Thusa ho fumana lefu la Parkinson kapa li-syndromes tse ling tsa parkinsonia, joalo ka lefu la Huntington;
• Tlhahlobo ea maloetse a methapo ea pelo a kang schizophrenia le khatello ea maikutlo;
• Etsa tlhahlobo ea kapele, taolo le ho iphetola ha mafu a methapo ea boko joalo ka stroke le mefuta e meng ea lipolao;
• Netefatsa lefu la boko;
• Tlhatlhobo ea likotsi tse mpe, li-hematoma tse ka tlung, li-abscesses le linyeoe tsa ho senyeha ha methapo;
• Tlhatlhobo ea liso tsa ho ruruha, joalo ka herpetic encephalitis, systemic lupus erythematosus, lefu la Behçet le ts'oaetso e amanang le HIV.

Khafetsa, scintigraphy ea boko e kopuoa ha ho na le lipelaelo mabapi le ts'oaetso ea lefu la methapo, hobane liteko tse joalo ka magnetic resonance le computed tomography, joalo ka ha li bonts'a liphetoho tse ling tsa sebopeho le sebopeho sa lisele tsa boko, li kanna tsa se lekane ho hlakisa linyeoe tse ling .

E etsoa joang

Ho etsa scintigraphy ea boko, ha ho hlokahale boitokiso bo khethehileng. Letsatsing la tlhatlhobo, ho khothaletsoa hore mokuli a phomole metsotso e ka bang 15 ho isa ho e 30, ka kamoreng e khutsitseng, ho fokotsa matšoenyeho, ho netefatsa boleng ba tlhatlhobo.

Ebe radiopharmaceutical, hangata e leng Technetium-99m kapa Thallium, e sebelisoa mothapong oa mokuli, o tlamehang ho emela bonyane hora e le 'ngoe ho fihlela ntho e kentsoe bokong hantle pele litšoantšo li ka nkuoa sesebelisoa ka metsotso e ka bang 40 ho isa ho e 60. . Nakong ena, ho hlokahala hore u lule u sa sisinyehe 'me u paqame, hobane motsamao o ka senya sebopeho sa litšoantšo.

Ebe mokuli o lokolloa bakeng sa mesebetsi e tloaelehileng. Hangata li-radiopharmaceuticals tse sebelisoang ha li bake likarabo kapa tšenyo efe kapa efe bophelong ba motho ea etsang tlhahlobo.

Ke mang ea sa lokelang ho etsa joalo

Cerebral scintigraphy ha e lumellane le basali ba baimana kapa ba anyesang, mme ba lokela ho tsebisoa moo ho nang le lipelaelo.
