Lung scintigraphy: Zvinoratidza akaongorora

Munguva ino yepamusorosoro mushonga achiedza kufambirana nguva uye kuva itsva nzira kundorondedzera womunhu muviri. The chikuru dzekuziva iri zvikuru mashoko, kuchengeteka, nyore uye vakaderera mutengo. Imwe nzira yakadaro pulmonary scintigraphy. Zvairatidza kuti nzira iyi zvikuru kwazvo, saka rinoshandiswa sezvo internists uye vanachiremba vanovhiya. Izvi zvinoita kuti tikwanise kuziva mazano kwokurapa uye zvakarurama kuwana dambudziko nzvimbo.

Lung scintigraphy: chii?

Scintigraphy - nzira X-ray Diagnostics, kushandiswa kuongorora mashandiro nhengo dzakavandika dzevanhu uye munyama. It unotora Kuropafadza kweropa hurongwa, uye negashiro radioactive isotopes nokuda nemwaranzi mufananidzo kurekodha, zvavakanga emit. The nzira pacharo riri kuitwa tichibatsirwa dzakananga michina kuti anogona kubata chiedza uye kuona izvozvo.

Lung scintigraphy rinoitwa kudzidza kweropa hurongwa mapapu uye kuziva kutyorwa kufefetedza. Kazhinji, pakupedzisira kuwana clots kana emboli kuti kuvhiringidza chakaipa chokubuda ropa. Munguva nzira, nzira mbiri kunyatsoongorora muviri ezvinhu anogona kushandiswa, zvichienderana chii mabasa pamberi chiremba:

- kufefetedza;
- perfusion.

Kufefetedza uye perfusion scintigraphy

Kufefetedza zvemapapu scintigraphy zvakafanira kuongorora kufema basa, zvinoratidza aibuda mhepo kupinda kufema hurongwa. Kuti aite izvi, varwere vanokurudzirwa fema imwe aerosol kuti rine radioisotopes, uye ipapo uchishandisa wegamma kamera kutarisa mberi kwavo mumuviri. Cold nharaunda dzinoratidza kuti aerosol kuti kuita izvozvo. Chiremba anogona kureva zvingangoitika zvinokonzera Fani iyi: stenosis, bundu, kuvapo emura kana atelectasis.

Perfusion zvemapapu scintigraphy pamwe pulmonary embolism nezvimwe zvirwere kweropa achibvumira Visualization of pulmonary midziyo uye kuona kufambira mberi ropa kubva kurudyi ventricle ari pulmonary tsinga. Asati kushanda pakuvheneka murwere nomutsinga raitongwa "Technetium-99", iro uchiora kupinda isotopes zvidiki uye nemwaranzi kubva kwacho kunonyora yacho wegamma kamera. Kana muviri akawanikwa nyika, iyo havana kugamuchira radioactive fuma, zviri kazhinji kuti lumen ari mudziyo chakavharwa imwe thrombus kana embolus.

zvairatidza nzira

Kana yakatarwa bapu scintigraphy? Zvairatidza - zvakadzama tsinga thrombophlebitis repasi maoko nemakumbo, chirwere pakati pulmonary embolism uye simba richiona kurapwa kwayo, kuziva zvinokonzera kuti pulmonary neBP , uye zvakawanda. Kuwedzera matambudziko vascular, vachishandisa scintigraphy anogona kuona dzichipfekeka mamiriro ari chiedza pamberi oparesheni unoparadza nguva-, tarisa kuvapo interstitial zvemapapu chirwere, uyewo kuvapo vachiberekwa zvirwere mwoyo nemapapu. Vanamukoti varayire zvemapapu scintigraphy kuti asava kana kusimbisa chisingaperi obstructive pulmonary chirwere uye mwoyo nokukundikana, emphysema, pulmonary infarction, kenza.

Contraindications

Lung scintigraphy hakurevi murwere upi nokudzidziswa zvakananga, mukusiyana kuti vakawanda invasive dzokuvhiya, zvakadai transesophageal echocardiography kana bronchoscopy.

Asi nzira pamberi kunokosha kuti allergoproby pamwe radioactive fuma kushandiswa kudzidzawo. Izvi kuitira kudzivisa kurwisa anaphylaxis munguva apo murwere achava mukati wegamma kamera. Kumisa sema kuita kwakaoma kupfuura kuzvidzivisa.

Kana firimu achava mukadzi, iye ndiongororwe imwe gayinakorojisiti kuti atonge fomu zvinobvira pamuviri, kana kuudza chiremba kuti mwana breastfed, sezvo radioisotopes kusvika mvura zvose, kusanganisira mukaka.

Hazvina varumbidzwa kwemaawa asingasviki mana pamberi nzira, zvinodhaka kana bismuth, barium, sezvo izvi zvingaita migumisiro pakudzidza.

Pfungwa scintigraphy

Maererano ongororo, zvemapapu scintigraphy zvinotora maminitsi chete maviri. Kuti kuitisa perfusion kudzidza, murwere akakumbirwa kupfeka wehunyambiri nechinzvimbo (sezvo mufananidzo zvichaita nani). Patient nomutsinga raitongwa chinodhaka, iyo ine radioactive isotopes, uye ipapo kutanga scan kuti aone mberi muropa inoramba. Vane diki zvokuti achawana kunyange rakamanikana midziyo.

Pakuita kufefetedza scintigraphy, murwere inhales ari aerosol sokuvapo chiedza haangavi dzishandise pakuenzanisa magasi. Radioactive nezvimedu vanotanga dziparare, uye kamera anogona anopamba nemwaranzi vaya dzine gasi angosimuka. Kana pashure nzira idzi mbiri akaratidza munharaunda apo pane kuremara perfusion, asi kufefetedza akaramba kuipa, asi ungangotarisa murwere pulmonary embolism.

yematambudziko

Kana munhu sema kuti, isotopes pamusoro zvezvinangwa, kurwadziwa uye kusagadzikana uchanzwira chete kana kuboora ganda. Munguva yokudzidza murwere ezvinhu utano kuti inogutsa. Kuda kurutsa, nomusoro, dzungu muri zvarakasiya kubva ndozvakajairwa, riri nani kuudza chiremba wako.

Usatya uye mwaranzi, nokuti kakawanda kuvatumwa zvakafanana munguva computed tomography kana rinobva resonance kuri. Chokwadi, munhu haagoni kutaura kuti kudzidza uri vakachengeteka zvakakwana, asi masayendisiti ari kushanda mibvunzo iyi kusvikira nhasi.

Reviews anoratidza: dzimwe nguva zvinoitika kuti migumisiro zvemapapu scintigraphy zvinogona kududzirwa kubva kumaonero akasiyana. Muzviitiko zvakadaro, kusimbisa chirwere zvaanofanira angiopulmonography. Kutongwa CT muropa aibuda murwere (kazhinji pashure pulmonary tsinga catheterization) raitongwa Mukupesana mumiririri iyo zvinofamba kuburikidza nhumbi mumapapu, achizadza zvose iripo nzvimbo yacho. Zvadaro, dzakatevedzana mifananidzo chiedza simba. Kana chiremba anoona nzvimbo apo pasina muenzaniso vascular, zvino, Ungangove, kune embolus.

надежным методом диагностики. Varwere vanoti zvemapapu scintigraphy chinodzidzisa, hwakavimbika uye nyarara chirwere nzira.
