Kutulutsa mpweya m'mapapo mwanga / perfusion scan

Kuwonetsetsa kwa mpweya m'mapapo / kupopera kumaphatikizapo mayesero awiri a nyukiliya kuti ayese kupuma (mpweya wabwino) ndi kufalitsa (perfusion) m'madera onse a mapapu.

Kuwunika kwamapapu / ma perfusion scan ndi mayeso awiri. Zitha kuchitidwa mosiyana kapena palimodzi.

Pakusanthula mafuta onunkhira, wothandizira zaumoyo amalowetsa ma radioin albumin mumtsinje wanu. Mumayikidwa patebulo losunthika lomwe lili m'manja mwa sikani. Makinawo amayang'ana m'mapapu anu pamene magazi amadutsamo kuti apeze komwe kuli ma radioactive particles.

Mukamayang'ana mpweya wabwino, mumapuma mpweya wamagetsi kudzera pachisoti mukakhala pansi kapena kugona pa tebulo pansi pa sikani.

Simuyenera kusiya kudya (mwachangu), muzidya zakudya zapadera, kapena kumwa mankhwala aliwonse musanayezedwe.

X-ray ya pachifuwa imachitika nthawi yayitali isanachitike kapena itatha mpweya wabwino.

Mumavala zovala zachipatala kapena zovala zabwino zomwe zilibe zomangira zachitsulo.

Gome likhoza kumverera lolimba kapena kuzizira. Mutha kumva kuwawa kwakuthwa IV ikayikidwa mtsempha m'manja mwanu chifukwa cha mafutawo.

Chigoba chomwe chimagwiritsidwa ntchito panthawi yojambulidwa ndi mpweya wabwino chimatha kukupangitsani kukhala ndi mantha kukhala muntunda yaying'ono (claustrophobia). Muyenera kugona chonchi panthawi yojambulira.

Jakisoni wa radioisotope nthawi zambiri samayambitsa vuto.

Kujambula kwa mpweya kumagwiritsidwa ntchito kuwona momwe mpweya ukuyendera komanso magazi akuyenda m'mapapu. Kujambula kwa perfusion kumayesa magazi kudzera m'mapapu.

Kuwonetsetsa kwa mpweya ndi perfusion kumachitika nthawi zambiri kuti muzindikire mawonekedwe am'mapapo (magazi a m'mapapu). Amagwiritsidwanso ntchito ku:

• Onani kutuluka kwachilendo (shunts) m'mitsempha yamagazi yamapapu (zotengera zam'mapapo)
• Yesani madera (mapapu osiyanasiyana) mapapu amagwirira ntchito mwa anthu omwe ali ndi matenda am'mapapo, monga COPD

Wothandizira ayenera kutenga mpweya wabwino ndi perfusion scan ndiyeno ayese ndi chifuwa x-ray. Magawo onse am'mapapu onse akuyenera kutenga radioisotope wogawana.

Ngati mapapo atenga zocheperako poyerekeza ndi ma radioisotope panthawi yopuma kapena kuwunikira, mwina chifukwa cha izi:

• Kutsekeka kwa ndege
• Matenda osokoneza bongo (COPD)
• Chibayo
• Kupondereza kwa mtsempha wamagazi
• Pneumonitis (kutupa m'mapapu chifukwa cha kupuma mwachilendo)
• Kuphatikiza kwamapapo
• Kuchepetsa kupuma ndi mpweya wabwino

Zowopsa ndizofanana ndi ma x-ray (radiation) ndi zibowo za singano.

Palibe radiation yomwe imamasulidwa kuchokera pa sikani. M'malo mwake, imazindikira kutentha kwa dzuwa ndikusintha kukhala chithunzi.

Pali kukhudzana pang'ono ndi radiation kuchokera pa radioisotope. Ma radioisotopes omwe amagwiritsidwa ntchito pazosanthula amakhala osakhalitsa. Ma radiation onsewa amatuluka mthupi m'masiku ochepa. Komabe, monga momwe zimakhalira ndi ma radiation, chenjezo limalangizidwa kwa amayi apakati kapena oyamwitsa.

Pali chiopsezo chochepa chothandizira kutenga matenda kapena kutuluka magazi pamalo omwe alowetsa singano. Chiwopsezo chofufuza mafuta onunkhira ndichofanana ndi kuyika singano yolowa mkati mwanjira ina iliyonse.

Nthawi zambiri, munthu amatha kukhala ndi vuto la radioisotope. Izi zitha kuphatikizira kuchitapo kanthu kwa anaphylactic.

Kutulutsa mpweya m'mapapo ndi kusungunula mafuta atha kukhala njira yocheperako poyerekeza ndi mapangidwe am'mapapo poyesa kusokonezeka kwa magazi am'mapapu.

Mayesowa sangapereke chidziwitso chotsimikizika, makamaka kwa anthu omwe ali ndi matenda am'mapapo. Mayeso ena angafunike kutsimikizira kapena kutsutsa zomwe zapezedwa m'mapapo a mpweya wabwino ndi kusinthana kwa perfusion.

Mayesowa adasinthidwa kwambiri ndi CT pulmonary angiography kuti athe kuzindikira kuphatikizika kwamapapu. Komabe, anthu omwe ali ndi vuto la impso kapena chifuwa chosiyanitsa utoto amatha kuyesedwa bwino.
