MRI mwoyo

Magnetic resonance kuri - chimwe chezvinhu anodzidzisa nzira Diagnostics ano. Nzira Izvi zvinoita kuti vawane mufananidzo yakasiyana kwemiviri uye panguva dzinongoitika inofamba uye ndakazorora. Uyezve, MRI Scans zvakaitwa 2-3 maberere dzakakwirira chisarudzo, hunobvumira iwe kuongorora dzichipfekeka zvechadenga nenyere.

MRI mu cardiology uye cardiac kuvhiyiwa chiri chaizvo kubatsira unyanzvi. Tichibatsirwa kudzidza mwoyo, anoita mavharuvhu, kuchinja zvose mwoyo makamuri panguva marwadzo inofamba ropa riyerere mumidziyo guru (pulmonary tsinga, yeropa). Pasina mubvunzo, MRI mifananidzo inokosha zvikuru mukudzidza chemwoyo, myocardial infarction uye ischemic mwoyo chirwere.

Sei munhu MRI mumwoyo?

Munguva nzira, mumwe murwere elektrovolnami achiisa imwe kwokunze remagineti. Masero Irradiated yokufungisisa nesimba remagetsi mwaranzi. Rwakadini Absorção de Água inonzi resonance, uye zvinokwanisika kuti kuyera. Mushure irradiation iri akamiswa masero zvakapiwa vakagamuchira simba, uye wakaiswa chaizvo sensors. Ongorora mifananidzo vakadzoka uye akagamuchira simba, purogiramu kombiyuta pave mifananidzo munyama pachena kuti nemwaranzi.

Record MRI akaita ultrathin zvidimbu mu akaturikidzana. Naizvozvo chiremba, kana inoongorora migumisiro kunogonawo kuona kuchinja kudzika mwoyo tishu.

Cardiac MRI rinoitwa sezvo nokushandiswa kusiyana nevasori, kana pasina, zvichienderana nezvinangwa uye yakananga mhosva. Kusiyana yomuchipatara anoshandiswa rokuongorora chakapfuura infarction, post-infarction, myocardial ischemia, uye anogumbura kuchinja.

Kazhinji, musiyano mumiririri ndiyo gadolinium - pakugadzirira gadopentetat dimeglumine (gadopentetate dimeglumine).

MRI kunoguma cardiology tikwanise kuona nzira hwokushanda pashure mwoyo kurwisa kumusoro nemazvo. By kuongorora kuchinja munyama nomwoyo, zvinokwanisika kuti zvakarurama kuisa kuzomukazve nokuda wakareruka wedzerai ropa (ischemia) kuchinja ventricular pamadziro. Ischemia chinokurwadzai mwero achidzikisa pavo. MRI anobvumira kudzidza zvakadzama rwakadini kuchinja izvi uye kusarudza coronary tsinga yokunzvenga kusonanidzwa. Kana myocardial nharaunda vaunganidza vakawedzera uwandu gadolinium, inoratidza kusingarapiki necrotic kuchinja mwoyo tishu. CABG Kuvhiya anogona kudzorera ropa aibuda, pavaigona kutora chikepe chaienda ari makavhara ropa riyerere nzvimbo. Asi kana iwe kuisa necrosis, kuvhiya hauchazopi zvinodiwa mugumisiro, kubudisa chinhu chaisafanira mutoro pamusoro muviri. Zvisinei, kana pasina necrosis, CABG kunze mwoyo murwere. Nokuda kwechikonzero ichi, cardiac MRI inoita basa rinokosha pakugadzirisa matambudziko cardiac.

Kana ichienzaniswa echocardiography kana MRI, positron anobuda tomography, zvinokwanisika kutaura rinotevera simba divi rinobva resonance kuri: kuunganidza gadolinium runoita kuona dzakakwirira zvakarurama non-zvimwe zvikamu uye chine musoro myocardium iri mukati tsandanyama rinenge mwoyo rusvingo.

MRI mwoyo: kuita zvesangano

The yezvinoreva MRI midziyo murwere nhema mira sezvo inofamba zvinoshatisa mufananidzo unhu. Nokuti nguva yose nzira inogona kutora pose kubva maminitsi 30 kusvika maminitsi 90. Office kuedzwa apo, zvakanaka yakavhenekerwa uye ventilated. Mune imwe ongororo yakaitwa vanachiremba mudonzvo anofanirwa nechokwadi yakanaka mamiriro murwere.

Contraindication kune MRI mufambiro zvinogona usimbiswe chinodzora kurova, simbi anodyara, uye nezvimwe zvinhu zvakafanana.

Vamwe havadi dzidzo chaiyo kuita cardiac MRI.
