La lung scintigraphy muedzo unotarisa kugoverwa kwemhepo neropa mumapapu uye kuongorora pulmonary embolism. Isu tinotaurawo nezve pulmonary scintigraphy yemhepo (mhepo) uye perfusion (ropa).

Scintigraphy is a imaging technique iyo inosanganisira kupa murwere a radioactive tracer, inopararira mumuviri kana munhengo kuti zviongororwe. Nokudaro, murwere ndiye "anobudisa" mwaranzi iyo ichatorwa nemudziyo (kusiyana neradiography, apo mhepo inobudiswa nemudziyo).

Muedzo uyu unoshandiswa kana vanofungidzirwa kuti pulmonary embolism, kusimbisa kana kuramba chirwere.

Pulmonary embolism inokonzerwa nea kuvhara ropa (thrombus) iyo inongoerekana yavhiringidza a tsinga remapapu. Zviratidzo hazvina kunyanya kujeka: kurwadziwa kwechipfuva, malaise, chikosoro chakaoma, etc. Kusiiwa kusina kurapwa, embolism inogona kuuraya mu30% yematambudziko. Naizvozvo injodzi yekurapa.

Kuti asimbise kana kuti abvise kuongororwa, vanachiremba vanogona kushandisa bvunzo dzekufungidzira, kunyanya CT angiography kana lung scintigraphy.

Iyi bvunzo inogona zvakare kunyorerwa:

• to cas of chirwere chemapapu chisingaperi, kuongorora kushanda kwokurapa kana kuti kutevera mhindumupindu;
• kutora ongororo kana zvichiitikakupfupika kusingatsananguriki.

Lung scintigraphy haidi kugadzirira kwakakosha uye haina kurwadziwa. Nekudaro, zvakakosha kuzivisa chiremba nezve chero mukana wekuita pamuviri.

Vasati vaongororwa, vashandi vezvokurapa vanobaya chigadzirwa chine radioactive zvishoma mutsinga iri muruoko rwomurwere. Chigadzirwa chacho chinosanganiswa neprotein aggregates (albumin) iyo inogara mumidziyo yemapapu, iyo inobvumira kuti ionekwe.

Kuti utore mifananidzo, iwe uchakumbirwa kurara pasi patafura yebvunzo. Kamera yakakosha (gamma-kamera kana scintillation kamera) ichafamba nekukurumidza pamusoro pako: uchafanirwa kufema gasi uchishandisa mask (radioactive krypton yakasanganiswa neokisijeni) kuti ikubvumire iwe kuona zvakare pulmonary alveoli. Nenzira iyi, chiremba anogona kuona kugoverwa kwemhepo neropa mumapapu.

Zvakakwana kuti ugare usina kufamba kwemaminitsi gumi nemashanu panguva yekutorwa kwemifananidzo.

Mushure mekuongorora, zvinokurudzirwa kunwa mvura yakawanda kuti zvive nyore kubviswa kwechigadzirwa.

Lung scintigraphy inogona kuratidza kusagadzikana kweiyo mhepo uye kutenderera kweropa mumapapu.

Zvichienderana nemigumisiro, chiremba acharatidza kurapwa kwakakodzera uye kutevera. Kana iri pulmonary embolism, kutarisirwa kwekukurumidzira kunodiwa, kwauchazopihwa anticoagulant kurapwa kunyungudutsa clot.

Dzimwe bvunzo dzinogona kudikanwa kuti uwane rumwe ruzivo (x-ray, CT scan, PET scan, bvunzo dzinoshanda dzekufema, nezvimwewo).
