M'mnyewa wamtima scintigraphy: kufotokoza ndondomeko, contraindications ndi ayamikira

Mu dziko zina zamakono walowa nthawi imene sayansi ndi mankhwala apite pamodzi ndi kuthandizana bwino. Kwenikweni ndi njira yatsopano ndi matenda matenda, kupeza iwo pa siteji ina. Tsopano milomo aliyense kulingalira maginito kumveka (Kujambula), nyukiliya maginito malumikizidwe (NMR), yopangidwa tomography (CT) ndipo ngakhale positron umuna tomography (PET). Koma kwa nthawi yaitali, pali njira ina udzakhalire chilengedwe mkati mwa thupi - m'mnyewa wamtima scintigraphy.

chimatanthauza

M'mnyewa wamtima scintigraphy - lakutali si olanda Kupenda mtima pogwiritsa ntchito particles nyukiliya. Ndipotu, lafalitsidwa cha kulowa deta isotopes mu thupi mu ndondomeko ya akukonzekera umuna awo.

M'mnyewa wamtima perfusion scintigraphy - makamaka phunziro lomwelo, monga tafotokozazi, koma ntchito nyukiliya thallium. Zinabala ngati mayesero nkhawa, ndipo popanda iwo. Iwo limakupatsani molondola anapereka cholinga cha ischemia, zomwe zimachititsa kuti chofunika kwambiri pa matenda a CHD (inatsekeratu matenda a mtima).

Aliyense - malinga ndi zosowa zake

Kuyambira 2007 mu US, kumadzulo kwa Ulaya ndi maiko ena olemera scintigraphy ambiri. utumiki uwu dokotala ntchito ndi anthu oposa khumi. Pali ndondomeko mwachilungamo chizolowezi kuti satenga nthawi yambiri ndiponso khama.

Soviet Union, zinthu kopambana osiyana. Panthawi mu Russia pali mazana awiri ndi ntchito makamera Popanga madzi a gamma kwa scintigraphy (poyerekeza ndi US khumi zikwi). Ndipo zilipo yekha pa mlingo wa chisamaliro ukachenjede.

Kodi ntchito?

Konzekerani ndi ndondomeko wodwalayo mankhwala ndi kutumikiridwa mu mtsempha-tracers zomwe zizindikiro vekitala molekyulu, ndi isotopes nyukiliya. ntchito yawo zogwirizana chifukwa vekitala ali tropism mankhwala (malo) kwa chiwalo kapena minofu ya m'thupi la munthu. isotope A limatulutsa mu danga owazungulira Popanga madzi a gamma kunyezimira. Register mtundu wa mafunde kudziwa malo wopambana ndipo choyipitsitsa kotunga magazi.

Izo zikusonyeza scintigraphy?

Ndiyamika njira zowonera akhoza bwinobwino kuwunika amayang'anitsitsa kotunga magazi minofu mtima wonse kapena m'madera osiyana. Pezani malo otaya kuchepa magazi, komanso kusiyanitsa pakati pa malo akufa mtima minofu, kuchokera kwa amene akhoza kupulumutsidwa. Mu positi-infarction odwala ndi wosavuta kudziwa zipsera ndi madera ischemia. Komanso, katswiri anganeneretu kuti zotsatira za kafukufuku, palibe mavuto ayembekezere ndi mmene posachedwapa.

zikuonetsa ndondomeko

Popeza njirayi - zosangalatsa mtengo ndithu, cholinga chake ayenera wolungama. Iwo ikuchitika milandu zotsatirazi:

1. Anthu athanzi pamaso zochitika zofunika zamasewera ndipo yaitali popanga munthu opaleshoni pogonekedwa ndi mankhwala ambiri kuthetsa kufala kwa mavuto kapena kuvulala.

2. matenda ya matenda a mitima, ngati muli prerequisites zonse chiphunzitso cha matenda amenewa.

3. Monga njira kuona mphamvu ya mankhwala: inatsekeratu mtsempha wamagazi kulambalala opaleshoni, angioplasty, mankhwala.

4. aletse ntchito mtima pambuyo m'mnyewa wamtima infarction (koma osati nthawi yomweyo pambuyo, monga kobwereza mtima kumachitika).

Monga ulamuliro, njira imeneyi zimathandiza inu molondola kupulumutsa matenda apakhungu ndi kutsimikizira izo.

Kukonzekera wodwalayo kwa ndondomeko

Musanadye mankhwala kapena ndondomeko matenda wodwala amalandira kuimilidwa ndi dokotala, kusunga zimene zingakuthandizeni kuti kafukufuku kokwanira kwambiri ndi zochepa yopweteka kwambiri kwa munthu:

- kafukufuku ikuchitika pa chopanda kanthu m'mimba;
- dzana sangathe kumwa khofi, "koka-Cola", tiyi, kudya chokoleti;
- muyenera kusiya kumwa mankhwala kukhazika mtima ntchito;
- kuchita ultrasound kuti akatsimikizire mimba, ndi amayi unamwino uyenera mkaka kukonzekera pasadakhale, monga mwana superekedwa bere kwa masiku awiri;
- Munthu dzana kuphunzira sayenera kugwiritsira ntchito mankhwala kusintha erections;
- sindilephera dokotala wanu ngati muli ndi mphumu iliyonse.

Kukonzekera wa radionuclides

Scintigraphy wa myocardium si popanda wothandizila nyukiliya. Awo tsopano alipo osiyanasiyana, malingana ndi cholinga cha phunziroli:

- MIBI kapena sestamibi ntchito phunziro la mtima, ali tropism kwa minofu mtima.

- mono- ndi bisphosphonates ndi kuyandikana kwa minofu fupa, ntchito matenda a khansa ndi mavuto ake, komanso kuvulala.

- asidi diethylenetriaminepentaacetic, limasonyeza kudwala aimpso.

- pertechnate ntchito kuphunzira chithokomiro England.

- ayodini 123 lakonzedwa kulingalira mabele England.

Pa pano msika pharmacological kale anaonekera mankhwala amene angakuthandizeni oterewa njira yeniyeni ya khansa. Mu thupi mankhwala awa kutumikiridwa m'nsinga, kotero muyenera kupeza pasadakhale ngati wodwalayo ali ndi ziwengo.

Chitani kuyezetsa

Kupanikizika m'mnyewa wamtima scintigraphy imagwiridwa chimodzimodzi monga phunziro analogical pa electrocardiography. Kuti akonze zinthu nkhawa, odwala akulimbikitsidwa kusonyeza pa masewero olimbitsa (matayala, njinga). The zikuonetsa kuti njirayi zofunika ECG kusintha, madandaulo, khalidwe la matenda a mitima. Mbali imodzi yovuta ndondomeko ndi kupeza kulingalira apamwamba a ventricle kumanzere. I chikhale chitsanzo olimbikitsa:

1. kumanzere yamitsempha yamagazi ejection kachigawo osakwana 35%.
2. Kuwonjezeka ejection kachigawo pa tima kwambiri ntchito kuposa 5%.
3. Chochititsa chidwi akuti matenda motility.
4. msokonezo Local wa contractility wa cardiomyocytes ndi katundu kochepa.

zotsatira scintigraphy

M'mnyewa wamtima scintigraphy amapereka mitundu ochepa mafano a minofu mtima. Choyamba, komabe otchedwa zithunzi malo amodzi. Izi ndi awiri azithunzi omwe tikunena (lathyathyathya) Thupi sanjira. Nthawi zambiri, kotero tione mafupa, zopangitsa za endocrine, ndi zina zotero D..

Chachiwiri, pali zithunzi zazikulu kapena kusuntha, kuti aone ntchito ziwalo dzenje. Iwo analandira chifukwa cha Kuwonjezera zithunzi Ena. Iwo amagwiritsa ntchito Kupenda chiwindi, impso, mtima, mitsempha ya magazi.

Chachitatu mtundu wa chonse cha phunziroli - ECG kalunzanitsidwe. kuchotsa zina ECG ndi limakupatsani perekani ntchito, ndi zimachititsa chilumbachi wa chotupa thupi.

Akatswiri ena, kuchititsa m'mnyewa wamtima scintigraphy, ndi kulumikiza OFEKT (osakwatira fotoni umuna yopangidwa tomography) kupeza zithunzi atatu azithunzi omwe tikunena wa limba mwafufuza. Nthawi zambiri izi zichitike milandu matenda amaganiziridwa mtima kapena ubongo.

ngati njira ndi otetezedwa?

Mu Russia, pokha pokha kwapadera, ndi m'mnyewa wamtima scintigraphy. Contraindications kafukufuku ndi losavuta: kupanda tilinazo munthu kwa radioisotope mankhwala. Komanso, ndondomeko ndi contraindicated mu:

- azimayi oyembekezera ndi azimayi unamwino;

- anthu ndi matenda aakulu a ziwalo zina ndi machitidwe (izo angalenge mavuto pa phunzirolo ntchito katundu);

- odwala sepsis ndi malungo;

- ndi myocarditis, pamaso pa matenda a mtima, ndipo posachedwapa m'mnyewa wamtima infarction.

The njira yokha ndi sabweretsa chisoni ndi pafupifupi vuto lililonse. Nthawi zina odwala kuona zotsatira zoyipa kwa mankhwala kapena zolimbitsa thupi, koma monga ulamuliro, ndi kusapeza akudutsa mwamsanga, ndipo anthu kubwerera ku moyo wabwinobwino.

Momwe pa phunzirolo

Kodi m'mnyewa wamtima scintigraphy? Sitepe yoyamba ndi kuyezedwa kuchipatala kapena pachipatala achire, kuti aone ngati pali kufunika kufufuza ngati mtengo. matenda a mtima angathe kuonedwa mosavuta njira zilipo.

Monga tanena zakale Soviet Union mwayi wochititsa chiyeso chotere chilipo pokhapokha m'mizinda ikuluikulu. M'mnyewa wamtima scintigraphy mu Moscow unachitikira ku zipatala zingapo lamtseri mu Center wa Interventional Cardiology mu RNII Gerontology moh RF, NC mtima Opaleshoni iwo. A. N. Bakuleva ndi dipatimenti cheza diagnostics MMA chipatala Center. I. M. Sechenova.

Mitengo mfundo m'zipatala boma ndi oziyimila paokha zingasiyane, nthawi zina kwambiri. Choncho, n'zomveka kuti kuganizira ntchito zoperekedwa ndi chipatala makamaka ndiyeno ife kusankha ali ndi kuchuluka anapempha kuti aziphunzira monga scintigraphy m'mnyewa wamtima. Price mu Moscow zingasiyane malingana ndi ndondomeko ndi kuchuluka kwa bwaloli. mtengo uli kwinakwake m'chigawo cha pakati pa asanu ndi asanu ndi atatu zikwi. Izi zikungofanana ndi kufufuza yosavuta. Koma pali odwala amene amafuna m'mnyewa wamtima scintigraphy katundu. mtengo wake udzakhala osachepera kawiri monga mkulu. Zikwi khumi ndi zisanu rubles, motero. Komabe, njira imeneyi amapereka dokotala lingaliro bwino za ukupeza wodwalayo komanso amathandiza kusankha mulingo woyenera ndondomeko mankhwala.

M'mnyewa wamtima scintigraphy - ndi watsopano, si olanda, otetezeka ndipo sabweretsa chisoni njira mosamala minofu mtima. Mwa kaphatikizidwe zomwe zamakono kompyuta ndi kufufuza mu munda wa zinthu nyukiliya chakhala zotheka matenda ischemic matenda a m'mapapo mu magawo ake oyambirira.
