Myocardial scintigraphy: tsanangudzo nzira, contraindications uye vanorumbidza

Mugore yepamusorosoro nyika wapinda munguva apo sayenzi nemishonga kuenda pamwe chete uye kubatsira mumwe kuvandudza. Kumboda ndiye nzira itsva chirwere nechirwere, Detective navo panguva imwe yapfuura rwakazara. Zvino miromo wose rinonzi magnetic resonance kuri (MRI), zvenyukireya rinobva resonance (NMR), computed tomography (CT) uye kunyange positron achine tomography (PET). Asi kwenguva yakareba, pane imwe nzira kuona womukati ezvinhu womunhu muviri - myocardial scintigraphy.

tsanangura

Myocardial scintigraphy - kumaruwa asiri invasive kuzviongorora mwoyo uchishandisa radioactive inoramba. Kutaura zvazviri, kuparadzirwa iyi date kupinda isotopes mumuviri iri muitiro kugadzira achine yavo.

Myocardial perfusion scintigraphy - kudzidza chete chaizvoizvo, sezvinorondedzerwa kumusoro, asi vachishandisa radioactive thallium. Yakabereka ari kunetseka bvunzo, uye pasina navo. Kunoitawo kuti zvakarurama kuisa ainyanya ischemia, izvo zvinoita chinokosha nechirwere pamusoro CHD (nechirwere chemwoyo).

Mumwe - maererano zvaaida

Kubva 2007 muna US, Western Europe uye dzimwe dzakabudirira scintigraphy kwakapararira. basa iri yezvokurapa rakashandiswa vanhu vanopfuura mamiriyoni gumi nemashanu ne. Pane zvakanaka nomuitiro muitiro usingabereki kutora nguva yakawanda nesimba.

Yaimbova Soviet Union, mamiriro acho ezvinhu ane zvikuru akasiyana. Panguva iyoyo kuRussia pane anenge mazana maviri uye nokushanda wegamma makamera kuti scintigraphy (zvichienzaniswa US gumi nezviviri). Uye dziripo chete pachiyero tertiary hanya.

Ungazviita sei?

Wakagadzirwa nzira murwere zvinodhaka chinotarisirwa mune tsinga-tracers iyo unotora munhu Vector Morekuru, uye radioactive isotopes. Basa ravo riri chokuita nokuti Vector ane tropism namakemikari (nzvimbo) chairo nhengo kana zvinyama dzemuviri. A isotope inongorira iri nzvimbo vakavapoteredza wegamma mwaranzi. Register iri mhando mafungu kuona nzvimbo yakanakisisa uye yakaipisisa ropa rive.

Izvi zvinoratidza scintigraphy?

Pamusana nzira iyi Visualization anogona kwazvo dzokorora uye kuyera ropa wedzerai mwoyo tsandanyama, yose kana mune dzakasiyana. Tsvaga nzvimbo ropa aibuda kukwana, uyewo kusiyanisa pakati kunzvimbo wakafa mwoyo rinenge kubva avo kuti achiri angaponeswa. In post-infarction varwere vari nyore kuona mavanga uye nzvimbo ischemia. Mukuwedzera, nyanzvi anogona kufanotaura migumisiro yechidzidzo, hapana matambudziko vanofanira kutarisira uye sei nokukurumidza.

zvairatidza nzira

Sezvo nzira iyi - mufaro zvinodhura zvikuru, chinangwa chacho anofanira kururamiswa. Voitakura kunze zvinotevera nyaya:

1. Nokuti utano vanhu vasati inokosha dzemitambo uye refu maoparesheni pasi vakawanda yokutindivadza kubvisa ngozi yematambudziko kana kukuvara.

2. Nokuti nechirwere zviri nechirwere chemwoyo, kana uine ose prerequisites kuti idzidziso kuti chirwere chakadai.

3. Sezvo nzira pakuongorora kubudirira mishonga: coronary tsinga ndavhiyiwa, angioplasty, zvinodhaka kurapa.

4. Kuti kutarisa mwoyo kushanda pashure myocardial infarction (asi kwete pakarepo pashure pacho, sezvinoita mwoyo kurwiswa idzokororo zvingaitika).

Kazhinji, nzira iyi kunoita kuti zvakarurama kununura kukamura uchishandisa chirwere uye ongorora nayo.

Kugadzirira murwere nokuti nzira

Asati kurapwa neimwe kana chirwere muitiro, murwere anogamuchira chiremba dzokurumbidza, kuchengetwa izvo zvichatibatsira kuita tsvakurudzo zvizere uye zvishoma zvinorwadza nokuda munhu:

- kutsvakurudza kuitwa usina chawadya;
- zuva asati haagoni kunwa kofi, "Coca-cola", tii, mudye chokoreti;
- unofanira kurega kushandisa zvinodhaka kuti pakudzikamisa mwoyo ushande;
- ita Ultrasound ushe kubva pamuviri, uye vanoyamwisa vanofanira mukaka kugadzirira pachine, sezvo mwana haana kupiwa chityu kwemazuva maviri;
- Munhu zuva pamberi kudzidza havafaniri kushandisa zvinodhaka kuvandudza erections;
- kuva nechokwadi kuudza chiremba wako kana muine asima.

kugadzirirwa radionuclides

Scintigraphy of myocardium haisi pasina kushandisa radioactive nevamiririri. Yavo iripo zvino marudzi mazhinji, zvichienderana nechinangwa pakudzidza:

- MIBI kana sestamibi rinoshandiswa kuti kudzidza mwoyo, ane tropism mwoyo tsandanyama.

- mono- uye bisphosphonates vane achida kuti mapfupa rinenge inoshandiswa nechirwere kenza uye ayo matambudziko, uyewo akuvara.

- diethylenetriaminepentaacetic acid, anozivisa renal zvokurwara.

- pertechnate aimbodzidza thyroid shwanu.

- ayodhini-123 rakagadzirirwa kuri kuti thyroid shwanu.

Panguva ino pamusika pharmacological akatooneka mishonga inogona kukubatsira kuziva chaizvo siyana kenza. In womunhu yeimwe aya akapiwa nomutsinga, saka unofanira kuziva pachine nguva kana murwere ane chisimbwa.

Exercise yokuedzwa

Stress myocardial scintigraphy rinoitwa zvakafanana sezvo analogical kudzidza pamusoro electrocardiography. Kusika zvinhu zvinoshungurudza, varwere vanokurudzirwa kuva panguva yokurovedza muviri (wekusimbisa muviri, bhasikoro). The zvairatidza kuti nzira iyi dzinokosha ECG kuchinja, zvichemo, yo nechirwere chemwoyo. Mumwe akaoma zvinobatanidzwa nzira ndiko kuwana yepamusoro kuri pakati ventricle kuruboshwe. Nzira dzekuziva nadzo zvakanaka mharidzo dziri:

1. kuruboshwe ventricular ejection chakapatsanurwa asingasviki 35%.
2. The kuwedzera ejection kesimba panguva kumwezve basa pane 5%.
3. Chinokosha mashoko motility zvirwere.
4. vachivavhiringidza yomunzvimbomo contractility pamusoro cardiomyocytes shoma mutoro.

zvabuda scintigraphy

Myocardial scintigraphy inopa mhando shoma mifananidzo zvomwoyo tsandanyama. Chekutanga, harisati anonzi kunofambira mberi mifananidzo. Uyu maviri-dimensional (sandarara) muviri Mapping. Kakawanda, saka ongorora mapfupa, kuti kwemakemikari anobudiswa omumuviri, uye zvichingodaro. D.

Chechipiri, pane simba kana uchifamba zvifananidzo, kuongorora basa negomba zvomukati. Vari vakawana somugumisiro kuwedzera zvishoma zvichiri mifananidzo. Ivo inoshandiswa chiropa kuzviongorora, itsvo, mwoyo, nemidziyo ropa.

Third mhando vanyorwa kudzidza - ECG yaunonyanya kushandisa. Zvimwe nokubviswa ECG unokubvumira kurongera basa, uye kwakaita nzvimbo yacho yose lesion muviri.

Dzimwe nyanzvi, kuitisa myocardial scintigraphy, uye batanidza OFEKT (kuroora photon achine computed tomography) kuwana-dimensional matatu mifananidzo aongororwe nenyere. Kazhinji izvi zvinoitwa vanenge mwoyo chirwere vanofungidzirwa kana uropi.

kana nzira yakachengeteka?

MuRussia chete muna aakatipa zviitiko, rimwe myocardial scintigraphy. Contraindications nokutsvakurudza iri nyore: kushayikwa nomumwe aikanganiswa zvinodhaka radioisotope. Uyezve, nzira iri contraindicated mu:

- Vakadzi vane pamuviri uye ekukurerai;

- vanhu vane kwazvo zvirwere nezvimwe nhengo uye hurongwa (ingakutemesa matambudziko pataidzidza uchishandisa mutoro);

- varwere sepsis uye fivhiri;

- pamwe myocarditis, kuvapo chemwoyo, uye munguva pfupi yapfuura myocardial infarction.

Nzira pachayo nyarara uye zvachose isingakuvadzi. Apo neapo, varwere vanotanga nemishonga kubva zvinodhaka kana kubva muviri, asi somunhu ushe, kusagadzikana inomhanya, uye vanhu vadzokere dzose upenyu.

Sei kuti kudzidza

Where myocardial scintigraphy kuitei? Danho rokutanga rinofanira munyaya kiriniki kana chipatara kuchirapa, kuona kana pane kudiwa pakutsvakurudza dzinodhura kwakadaro. mwoyo chirwere zhinji unogona kuonekwa nyore nzira iripo.

Sezvataurwa pamusoro apa, yaimbova Soviet Union mukana kuitisa bvunzo yakadaro inowanikwa chete mumaguta makuru. Myocardial scintigraphy muMoscow rakaitirwa private makiriniki vanoverengeka uyewo pakati Interventional Cardiology muna RNII Gerontology Moh RF, NC zvemwoyo Surgery navo. A. N.

Saka, zvine musoro kuti kunyatsoongorora mabasa zvaipiwa muchipatara zvikuru uye ipapo isu usarudze vanogutsikana mari akakumbira chakadaro kudzidza sezvo myocardial scintigraphy. Price muMoscow dzingasiyana zvichienderana nzira uye kutsanangurwa yacho. Mari iri imwe nzvimbo munzvimbo pakati manomwe nezvisere zviuru. Izvi ndizvo chaizvo kuti nyore tsvakurudzo. Asi pane varwere zvinoda myocardial scintigraphy mutoro. mutengo wayo achava kanenge kaviri sezvo mukuru. Gumi nezvishanu rubles, ukuwo. Zvisinei, nzira iyi kunoita chiremba pfungwa nani pamusoro mamiriro eutano murwere uye inobatsirawo wasarudza Zvakanyanya Kunaka Panguva Yepamuviri kurapwa itsika.

Myocardial scintigraphy - a yerudzi rutsva, dzisiri invasive, wakachengeteka uye nyarara nzira kuongorora mwoyo tsandanyama. Nokuva nokubudirira yazvino kombiyuta uye Zvakawanikwa mumunda radioactive zvinhu yava zvichibvira rokuongorora ischemic zvirwere zvemapapu mu vepakutanga huchiri.
