La i-lung scintigraphy ukuhlola okubheka ukusatshalaliswa komoya negazi emaphashini futhi kuhlonzwe i-pulmonary embolism. Siphinde sikhulume nge-pulmonary scintigraphy ye-ventilation (umoya) kanye ne-perfusion (igazi).

IScintigraphy iyi- izithombe zobuchwepheshe okuqukethe ukwelapha isiguli a i-radioactive tracer, esibhebhetheka emzimbeni noma ezithweni ukuze zihlolwe. Ngakho-ke, yisiguli "esikhipha" imisebe ezolandwa yidivayisi (ngokungafani ne-radiography, lapho imisebe ikhishwa khona yidivayisi).

Lesi sivivinyo sisetshenziswa uma kwenzeka okusolwayo embolism yamaphaphu, ukuqinisekisa noma ukuphika ukuxilongwa.

I-Pulmonary embolism ibangelwa a ihluli (i-thrombus) evimbela ngokuzumayo a umthambo we-pulmonary. Izimpawu azicacile kakhulu: ubuhlungu besifuba, i-malaise, ukukhwehlela okomile, njll. Uma kungelashwa, i-embolism ingaba yingozi ku-30% yamacala. Ngakho-ke kuyisimo esiphuthumayo sezokwelapha.

Ukuqinisekisa noma ukukhipha ukuxilongwa, odokotela bangasebenzisa ukuhlolwa kwe-imaging, ikakhulukazi i-CT angiography noma i-lung scintigraphy.

Lokhu kuhlolwa kungamiselwa futhi:

• kuya ku-cas of isifo samaphaphu esingamahlalakhona, ukuhlola ukusebenza kokwelashwa noma ukulandela ukuziphendukela kwemvelo;
• ukuthatha isitoko uma kwenzekaukuphelelwa umoya okungachazeki.

I-Lung scintigraphy ayidingi ukulungiswa okukhethekile futhi ayibuhlungu. Kodwa-ke, kubalulekile ukwazisa udokotela nganoma yikuphi ukukhulelwa okungenzeka.

Ngaphambi kokuhlolwa, abasebenzi bezokwelapha bajova umkhiqizo okhipha imisebe kancane emthanjeni osengalweni yesiguli. Umkhiqizo uhlanganiswe nama-protein aggregates (albumin) azofaka emithanjeni yamaphaphu, evumela ukuthi ibonakale.

Ukuthatha izithombe, uzocelwa ukuba ulale etafuleni lokuhlola. Ikhamera eyisipesheli (ikhamera ye-gamma noma ikhamera ye-scintillation) izohamba ngokushesha ngaphezu kwakho: kuzodingeka uphefumule igesi usebenzisa imaski (i-krypton yomsakazo exutshwe nomoya-mpilo) ukuze ikuvumele ukuthi ukwazi ukubona ngeso lengqondo i-alveoli yamaphaphu. Ngale ndlela, udokotela angakwazi ukubona ukusatshalaliswa komoya negazi emaphashini.

Kwanele ukuhlala kunganyakazi imizuzu eyishumi nanhlanu ngesikhathi kutholwa izithombe.

Ngemuva kokuhlolwa, kungakuhle ukuthi uphuze amanzi amaningi ukwenza lula ukuqedwa komkhiqizo.

I-Lung scintigraphy ingaveza okungavamile kwe- umoya nokujikeleza kwegazi emaphashini.

Ngokuya ngemiphumela, udokotela uzophakamisa ukwelashwa okufanele nokulandelwa. Uma kwenzeka i-pulmonary embolism, ukunakekelwa okuphuthumayo kuyadingeka, lapho uzonikezwa khona ukwelashwa kwe-anticoagulant ukuncibilikisa ihlule.

Okunye ukuhlolwa kungase kudingeke ukuze uthole ulwazi olwengeziwe (i-x-ray, i-CT scan, i-PET scan, ukuhlolwa okusebenzayo kokuphefumula, njll.).
