La mob ntsws scintigraphy yog ib qho kev ntsuam xyuas uas saib ntawm kev faib tawm ntawm huab cua thiab ntshav hauv lub ntsws thiab kuaj xyuas pulmonary embolism. Peb kuj hais txog pulmonary scintigraphy ntawm qhov cua (cua) thiab perfusion (ntshav).

Scintigraphy yog ib qho kev siv duab uas muaj nyob rau hauv kev tswj hwm tus neeg mob a radioactive taug qab, uas kis tau nyob rau hauv lub cev los yog nyob rau hauv lub cev los mus kuaj. Yog li, nws yog tus neeg mob uas "tso" cov hluav taws xob uas yuav raug khaws los ntawm lub cuab yeej (tsis zoo li radiography, qhov twg cov hluav taws xob tawm ntawm lub cuab yeej).

Qhov kev kuaj no yog siv rau hauv cov ntaub ntawv xav tias pulmonary embolism, kom paub meej lossis tsis lees paub qhov kev kuaj mob.

Pulmonary embolism yog tshwm sim los ntawm a ntshav txhaws (thrombus) uas dheev obstructs a pulmonary leeg. Cov cim qhia tsis meej heev: mob hauv siab, mob plab, hnoos qhuav, thiab lwm yam. Sab laug tsis kho, embolism tuaj yeem ua rau tuag taus hauv 30% ntawm cov neeg mob. Yog li ntawd nws yog ib qho kev kho mob xwm txheej ceev.

Txhawm rau kom paub meej lossis txiav tawm qhov kev kuaj mob, cov kws kho mob tuaj yeem siv cov kev kuaj pom, tshwj xeeb tshaj yog CT angiography lossis lub ntsws scintigraphy.

Qhov kev ntsuam xyuas no kuj tuaj yeem raug sau tseg:

• li cas mob ntsws mob, los ntsuas qhov ua tau zoo ntawm kev kho mob lossis ua raws li kev hloov pauv;
• coj Tshuag nyob rau hauv qhov kev tshwm sim ntawmua tsis taus pa tsis tau piav qhia.

Lub ntsws scintigraphy tsis xav tau kev npaj tshwj xeeb thiab tsis mob. Txawm li cas los xij, nws yog ib qho tseem ceeb kom qhia rau tus kws kho mob txog qhov muaj feem yuav xeeb tub.

Ua ntej kev kuaj mob, cov neeg ua haujlwm kho mob tau txhaj tshuaj me ntsis cov khoom siv hluav taws xob rau hauv cov hlab ntsha ntawm tus neeg mob caj npab. Cov khoom yog ua ke rau cov protein aggregates (albumin) uas yuav nyob hauv cov hlab ntsws, uas tso cai rau lawv pom.

Txhawm rau thaij duab, koj yuav raug hais kom pw ntawm lub rooj kuaj mob. Lub koob yees duab tshwj xeeb (gamma-lub koob yees duab lossis lub koob yees duab scintillation) yuav txav nrawm dua ntawm koj: koj yuav tsum tau nqus cov pa siv lub npog ntsej muag (krypton sib xyaw nrog oxygen) kom koj tuaj yeem pom cov pulmonary alveoli. Ua li no, tus kws kho mob tuaj yeem soj ntsuam qhov kev faib tawm ntawm huab cua thiab ntshav hauv lub ntsws.

Nws yog qhov txaus los nyob twj ywm tsis pub dhau kaum tsib feeb thaum lub sijhawm tau txais cov duab.

Tom qab kev tshuaj xyuas, nws raug nquahu kom haus dej kom ntau los pab tshem tawm cov khoom lag luam.

Lub ntsws scintigraphy tuaj yeem qhia qhov txawv txav ntawm cov cua thiab ntshav ncig hauv lub ntsws.

Raws li qhov tshwm sim, tus kws kho mob yuav qhia txog kev kho mob thiab ua raws li qhov tsim nyog. Nyob rau hauv cov ntaub ntawv ntawm pulmonary embolism, yuav tsum tau saib xyuas ceev, qhov twg koj yuav tau txais ib tug Kev kho mob anticoagulant kom yaj lub clot.

Lwm yam kev ntsuam xyuas yuav tsim nyog kom tau txais cov ntaub ntawv ntau ntxiv (x-ray, CT scan, PET scan, kev kuaj ua pa, thiab lwm yam).
