Pulmonary kufefetedza / perfusion scan

Kuvhenekera kwemapapu / perfusion scan inosanganisira miviri yekuongorora kwenyukireya kuyera kufema (kufefetedza) uye kutenderera (perfusion) munzvimbo dzese dzemapapu.

Iyo pulmonary kufefetedza / perfusion scan ndiyo chaiyo 2 bvunzo. Zvinogona kuitwa zvakasiyana kana pamwechete.

Munguva yeiyo perfusion scan, mutapi wezvehutano anojekesa radioactive albumin mutsinga yako. Iwe unoiswa patafura inofambiswa iri pasi pe ruoko rwe scanner. Mushini unoongorora mapapu ako sezvo ropa richiyerera nepakati pavo kuti uwane panowanikwa ma radioactive particles.

Munguva yekuvhenekesa mweya, iwe unofema mune radioactive gasi kuburikidza nemask pawakagara kana wakarara patafura pasi pe scanner ruoko.

Iwe haufanire kurega kudya (nekukurumidza), kuve pachikafu chakakosha, kana kutora chero mishonga usati waedzwa.

Bhokisi x-ray rinowanzoitwa pamberi kana mushure mekufefetera uye perfusion scan.

Unopfeka hanzu yechipatara kana mbatya dzakagadzikana dzisina zvekusunga simbi.

Tafura yacho inogona kunzwa yakaoma kana kutonhora. Iwe unogona kunzwa kubaya kwakapinza kana IV ikaiswa mutsinga muruoko rwako rwechikamu cheperefiyumu che scan.

Iyo maski inoshandiswa panguva yekufefetedza scan inoita kuti unzwe kutya pamusoro pekuve mune diki nzvimbo (claustrophobia). Unofanira kunyepera kunyarara panguva yekutarisa.

Iyo radioisotope jekiseni kazhinji haikonzere kusagadzikana.

Iyo yekufefetera scan inoshandiswa kuona kuti mweya unofamba zvakanaka sei uye neropa rinoyerera mumapapu. Iyo perfusion scan inoyera kuyerwa kweropa kuburikidza nemapapu.

Kufefetedza uye perfusion scan inowanzoitwa kuti itore pulmonary embolus (ropa clot mumapapu). Izvo zvinoshandiswa zvakare ku:

• Tsvaga kutenderera kusingaenzanisike (shunts) mumidziyo yeropa yemapapu (pulmonary vessels)
• Edza matunhu (akasiyana mapapu nzvimbo) yemapapu inoshanda muvanhu vane yepamusoro pulmonary chirwere, senge COPD

Iye mupi anofanira kutora mweya uye perfusion scan uye wozoiongorora nechipfuva x-ray. Mativi ese emapapu ese anofanira kutora radioisotope zvakaenzana.

Kana mapapu achitora akadzika kupfuura akajairwa ma radioisotope panguva yekufefetera kana perfusion scan, inogona kunge iri nekuda kwechero yeanotevera:

• Kuvharika kwemumhepo
• Chirwere chisingaperi chinodzivirira pulmonary chirwere (COPD)
• Chirwere chemabayo
• Kuderedza kweye pulmonary arteri
• Pneumonitis (kuzvimba kwemapapu nekuda kwekufema mune chinhu chekunze)
• Pulmonary embolus
• Kuderedza kufema uye kugona mweya

Njodzi dzakada kufanana nezve x-ray (radiation) uye tsono dzinobaya.

Hapana radiation yakaburitswa kubva ku scanner. Pane kudaro, inoona radiation uye inoichinja kuita mufananidzo.

Iko kune kudonhedzwa kudiki kune radiation kubva kune radioisotope. Iwo ma radioisotopu anoshandiswa panguva yekuwongorora anorarama kwenguva pfupi. Ose radiation anosiya muviri mumazuva mashoma. Nekudaro, sekufanana nekuratidzwa kwemwaranzi, yambiro inokurudzirwa kune vakadzi vane nhumbu kana vanoyamwisa.

Pane njodzi diki yekutapukirwa kana kubuda ropa panzvimbo inoiswa tsono. Ngozi ine perfusion scan yakafanana nekuisa tsono inopinza kune chero chimwe chinangwa.

Muzviitiko zvisingawanzoitika, munhu anogona kukura chisimbwa kune radioisotope. Izvi zvinogona kusanganisira yakakomba anaphylactic reaction.

Iyo pulmonary kufefetedza uye perfusion scan inogona kunge iri yakaderera-njodzi nzira kune pulmonary angiography yekuongorora kusagadzikana kwemapapu eropa kupa.

Uyu muedzo haugone kupa yakatarwa kuongororwa, kunyanya kune vanhu vane chirwere chemapapu. Mimwe miedzo inogona kudikanwa kuti isimbise kana kutonga kunze kwekuwanikwa kwepulmonary kufefetedza uye perfusion scan.

Uyu muedzo wakanyanya kutsiviwa neTC pulmonary angiography yekuongorora pulmonary embolism. Nekudaro, vanhu vane matambudziko eitsvo kana allergy yekusiyanisa dhayi vanogona zvakanyanya kuve nemuyedzo uyu.
