Cerebral scintigraphy, dzina lake lolondola ndi cerebral perfusion tomography scintigraphy (SPECT), ndimayeso omwe amachitika kuti azindikire kusintha kwa kayendedwe ka magazi ndi magwiridwe antchito aubongo, ndipo nthawi zambiri amachitidwa kuti athandizire kuzindikira kapena kuwunika matenda opatsirana aubongo, monga Alzheimer's, Parkinson's kapena chotupa, makamaka ngati mayeso ena monga MRI kapena CT scan sakukwanira kutsimikizira kukayikira.

Kuyeza kwa ubongo kumachitika ndi jakisoni wa mankhwala omwe amatchedwa ma radiopharmaceuticals kapena ma radiotracers, omwe amatha kudzikonza okha mu minofu yaubongo, kulola kupangidwa kwa zithunzi muchipangizocho.

Scintigraphy imachitidwa ndi adotolo, ndipo imatha kuchitika mzipatala kapena zipatala zomwe zimayesa mayeso a mankhwala a nyukiliya, pempho lachipatala, kudzera ku SUS, mapangano ena, kapena mwamseri.

Ndi chiyani

Cerebral scintigraphy imapereka chidziwitso chakuwonjezera kwa magazi ndi magwiridwe antchito aubongo, zothandiza kwambiri ngati:

• Sakani matenda amisala, monga Alzheimer's kapena Lewy corpuscle dementia;
• Dziwani cholinga cha khunyu;
• Onetsetsani zotupa zamaubongo;
• Thandizani kuzindikira matenda a Parkinson kapena ma syndromes ena a parkinsonia, monga matenda a Huntington;
• Kuunika kwa matenda amitsempha yam'mitsempha monga schizophrenia ndi kukhumudwa;
• Pangani matenda, kuwongolera komanso kusintha kwakanthawi kwamatenda am'mitsempha monga sitiroko ndi mitundu ina ya sitiroko;
• Tsimikizani kufa kwaubongo;
• Kuwunika kwa kuvulala koopsa, ma hematomas ochepera, zotupa ndi zovuta zamatenda;
• Kufufuza kwa zotupa zotupa, monga herpetic encephalitis, systemic lupus erythematosus, matenda a Behçet ndi encephalopathy yokhudzana ndi HIV.

Nthawi zambiri, scintigraphy yaubongo imafunsidwa kukayikira zakupezeka kwa matenda amitsempha, popeza mayesero monga maginito resonance ndi computed tomography, popeza akuwonetsa kusintha kwamapangidwe komanso mawonekedwe am'mimba yaubongo, sangakhale okwanira kufotokoza zina .

Momwe zimachitikira

Kuti muchite zowonera muubongo, palibe kukonzekera kofunikira. Patsiku la mayeso, ndikulimbikitsidwa kuti wodwalayo apumule kwa mphindi pafupifupi 15 mpaka 30, mchipinda chodekha, kuti muchepetse nkhawa, kuti muwonetsetse mayeso abwino.

Kenako, radiopharmaceutical, yomwe nthawi zambiri imakhala Technetium-99m kapena Thallium, imagwiritsidwa ntchito pamitsempha ya wodwalayo, yomwe imayenera kudikirira ola limodzi mpaka mankhwalawo atakhazikika muubongo zithunzi zisanatengeredwe pachipangizocho kwa mphindi 40 mpaka 60 . Munthawi imeneyi, ndikofunikira kukhalabe osayenda ndi kugona pansi, chifukwa kuyenda kumatha kusokoneza mapangidwe azithunzi.

Kenako wodwalayo amamasulidwa kuti achite ntchito zabwinobwino. Ma radiopharmaceuticals omwe amagwiritsidwa ntchito samakonda kuyambitsa machitidwe kapena kuwonongeka kwa thanzi la munthu amene amayesa mayeso.

Yemwe sayenera kuchita

Cerebral scintigraphy imatsutsana ndi azimayi omwe ali ndi pakati kapena akuyamwitsa, ndipo ayenera kudziwitsidwa pamaso pa kukayikira kulikonse.
