I-Cerebral scintigraphy, egama layo elifanele kakhulu yi-cerebral perfusion tomography scintigraphy (SPECT), ukuhlolwa okwenziwa ukuthola izinguquko ekujikelezeni kwegazi nokusebenza kobuchopho, futhi kuvame ukwenziwa ukusiza ekuhlonzeni noma ekuqapheleni izifo zobuchopho eziwohlozayo, njenge-Alzheimer's, Parkinson's noma isimila, ikakhulukazi lapho okunye ukuhlolwa okufana ne-MRI noma i-CT scan kunganele ukuqinisekisa izinsolo.

Ukuhlolwa kwe-cerebral scintigraphy kwenziwa ngomjovo wemithi ebizwa ngama-radiopharmaceuticals noma ama-radiotracers, akwazi ukuzilungisa ezicutshini zobuchopho, avumele ukwakheka kwezithombe ocingweni.

I-Scintigraphy yenziwa ngudokotela, futhi ingenziwa ezibhedlela noma emitholampilo eyenza izivivinyo zemithi yenuzi, ngesicelo esifanele sezokwelapha, nge-SUS, ngezivumelwano ezithile, noma ngendlela yangasese.

Yenzelwe ini

I-Cerebral scintigraphy inikeza imininingwane ngokugcotshwa kwegazi nokusebenza kobuchopho, ilusizo kakhulu ezimweni ezinjengalezi:

• Sesha ukuwohloka komqondo, njenge-Alzheimer's noma i-Lewy corpuscle dementia;
• Ukubona okugxilwe yisifo sokuwa;
• Hlola izimila zobuchopho;
• Siza ekutholeni isifo sikaParkinson noma amanye ama-syndromes e-parkinsonia, njengesifo sikaHuntington;
• Ukuhlolwa kwezifo ze-neuropsychiatric ezifana ne-schizophrenia nokudangala;
• Yenza ukuxilongwa, ukulawula kanye nokuvela kwesifo se-vascular brain okufana nokushaywa unhlangothi nezinye izinhlobo zohlangothi;
• Qinisekisa ukufa kwengqondo;
• Ukuhlolwa kokulimala okuhlukumezayo, ama-hematomas angaphansi, ama-abscesses namacala we-malformation malformation;
• Ukuhlolwa kwesilonda sokuvuvukala, njenge-herpetic encephalitis, i-systemic lupus erythematosus, isifo sikaBehçet kanye ne-encephalopathy ehlobene ne-HIV.

Imvamisa, ukucelwa kwe-scintigraphy kobuchopho kuyacelwa lapho kunokungabaza maqondana nokutholakala kwesifo sezinzwa, ngoba izivivinyo ezinjenge-magnetic resonance kanye ne-computed tomography, njengoba zikhombisa izinguquko ezengeziwe zokwakheka kanye nokwakheka kwezicubu zobuchopho, kungahle kunganeli ukucacisa amanye amacala .

Kwenziwa kanjani

Ukwenza i-cerebral scintigraphy, akukho ukulungiselela okuthile okudingekayo. Ngosuku lokuhlolwa, kunconywa ukuthi isiguli siphumule cishe imizuzu eyi-15 kuye kwengama-30, egumbini elinokuthula, ukunciphisa ukukhathazeka, ukuqinisekisa ikhwalithi engcono yokuhlolwa.

Ngemuva kwalokho, i-radiopharmaceutical, imvamisa i-Technetium-99m noma i-Thallium, isetshenziswa emthanjeni wesiguli, okumele silinde okungenani ihora elilodwa kuze kube ukuthi into leyo igxilwe kahle ebuchosheni ngaphambi kokuba izithombe zithathwe kule nto cishe imizuzu engama-40 kuya kwengu-60 . Ngalesi sikhathi, kuyadingeka ukuthi uhlale unganyakazi futhi ulale phansi, ngoba ukunyakaza kungaphazamisa ukwakheka kwezithombe.

Ngemuva kwalokho isiguli siyadedelwa senze imisebenzi ejwayelekile. Ama-radiopharmaceuticals asetshenziswayo awavamisile ukudala ukusabela noma umonakalo emfundweni yomuntu owenza lolu vivinyo.

Ubani okungafanele akwenze

I-Cerebral scintigraphy iyaphikiswa kwabesifazane abakhulelwe noma abancelisayo, futhi kufanele baziswe lapho kukhona okusolisayo.
