Cerebral scintigraphy, rine zita rakanyatsojeka inonzi cerebral perfusion tomography scintigraphy (SPECT), bvunzo inoitwa kuona shanduko mukutenderera kweropa uye mashandiro ehuropi, uye inowanzoitirwa kubatsira mukucherechedzwa kana kuongororwa kweanodzikira hosha dzehuropi, seAlzheimer's, Parkinson's kana bundu, kunyanya kana kumwe kuyedzwa kwakafanana neMRI kana CT scan kusingakwanise kusimbisa fungidziro.

Iyo cerebral scintigraphy bvunzo inoitwa pamwe jekiseni remishonga inonzi radiopharmaceuticals kana radiotracers, iyo inokwanisa kuzvigadzirisa pachavo muhuropi turu, ichibvumira kuumbwa kwemifananidzo muchigadzirwa.

Scintigraphy inoitwa nachiremba, uye inogona kuitwa muzvipatara kana makiriniki anoita bvunzo dzemishonga yenyukireya, nechikumbiro chakakodzera chekurapwa, kuburikidza neSUS, zvimwe zvibvumirano, kana nenzira yakavanzika.

Chii ichochi

Cerebral scintigraphy inopa ruzivo pamusoro perfusion yeropa uye kushanda kwehuropi, inobatsira kwazvo mumamiriro ezvinhu akadai se:

• Tsvaga dementias, senge Alzheimer's kana Lewy corpuscle dementia;
• Ziva chinotarisa pfari;
• Ongorora mamota europi;
• Batsira mukuongororwa kwechirwere chePasinson kana mamwe mapaki eparkinsonia, senge chirwere chaHuntington;
• Kuongororwa kwezvirwere zveurouropsychiatric senge schizophrenia uye kushushikana;
• Ita chirwere chekutanga, kutonga uye shanduko yezvirwere zvevascular senge sitiroko uye mamwe marudzi eshamhu
• Simbisa kufa kwehuropi;
• Kuongororwa kwekukuvara kunorwadza, subdural hematomas, abscesses uye kesi dzevascular malformation;
• Kuongororwa kwechirwere chinopisa, senge herpetic encephalitis, systemic lupus erythematosus, chirwere cheBehçet uye encephalopathy inosangana neHIV.

Kazhinji, uropi scintigraphy hunokumbirwa kana paine kusahadzika maererano nekuongororwa kwechirwere chetsinga, sezvo bvunzo dzakadai semagineti resonance uye computed tomography, sezvavanoratidza zvimwe shanduko uye mune maitiro ehuropi matishu, zvinogona kunge zvisina kukwana kujekesa zvimwe zviitiko .

Zvinoitwa sei

Kuti uite cerebral scintigraphy, hapana chaiyo gadziriro inodiwa. Pazuva rebvunzo, zvinokurudzirwa kuti murwere azorore kwemaminetsi gumi nemashanu kusvika makumi matatu, mune imwe imba yakanyarara, kudzikamisa kushushikana, kuve nechokwadi chebvunzo.

Zvino, iyo radiopharmaceutical, kazhinji Technetium-99m kana Thallium, inoiswa mutsinga yemurwere, iyo inofanirwa kumirira kweinenge 1 awa kusvikira chinhu chacho chakanyatsomira muuropi mifananidzo isati yatorwa pachigadzirwa kwemaminitsi makumi mana kusvika makumi matanhatu. . Munguva iyi, zvakakosha kuti ugare wakamira uye wakarara pasi, sezvo kufamba kuchikanganisa kuumbwa kwemifananidzo.

Ipapo murwere anosunungurwa kuitira zvakajairika zviitiko. Radiopharmaceuticals anoshandiswa haawanzo kukonzera maitiro kana chero kukuvara kune hutano hwemunhu anoita bvunzo.

Ndiani asingafanire kuita

Cerebral scintigraphy inopesana nevakadzi vane pamuviri kana kuyamwisa, uye vanofanirwa kuziviswa pamberi pekufungidzira.
