MRI o ka naau

ʻume mākenēki resonance kiʻi - o kekahi o ka loa informative ano o kēia lapaʻau 'ana. Keia papa hana i ka mea e hiki ai e loaa i ke kiʻi o kaʻokoʻa kino, a ma ka manawa o maoli ka noi, a ma koena. Eia hou kekahi, MRI scan NineManga.com hana i 2-3 nā wānana waiwai me kiʻekiʻe olelo hooholo, e leie aku oe, e makaikai i ka iaea ooieoeiiaeuiiai ano o ka hui,.

MRI ma cardiology a cardiacʻoki kino o ka loa maikaʻi kēiaʻano hana. Me ke kōkua o këia ka naau, ma ka contraction noi o ke koko i loko o na moku nui (pulmonary artery, aorta) i ka hana o ka nohona kiwikā, hou i loko o nā mea a pau naʻau ke Keena. Oiaio no, o ka MRI kiʻi i paʻa i loko o ke ao o ka naau maʻi, myocardial infarction a me ischemic naʻau maʻi.

Pehea i ka MRI o ka naau?

Iloko o ke kaʻina hana, he ahonui elektrovolnami waiho i loko o ka mawaho ʻume mākenēki kahua. Irradiated keena mēkene i ka ikaika o ka electromagnetic a pāhawewe. Loa o ke omo ua kapaia resonance, a me ia mea e hiki ke ana. Ma hope o ka irradiation ua 'ōlelo, i haawiia mai na keena a hiki i ka ikehu loaa mai, a ua paa me ka kūikawā nā mea e loaʻa ka mea nalo. Ke kālailai i nā kiʻi hoi mai la, a loaa ka mana, i ka polokalamu kamepiula hana kiʻi o nā'aʻaʻa paku ole ia i ka pāhawewe.

Record MRI hana ultrathin slices ma ka papa. No ia mea, ke kauka, ia ia kālailai i nā hualoaʻa ke i ike i ka loli i loko o ka hohonu o ka naau'aʻaʻa.

Cardiac MRI ua lawe mai like me ka hoʻohana 'ana o ka Akä naÿe no nä konohiki, a me ka ole, ke kaumaha ma muli o nā Pahuhopu a me kekahi hihia. Akä naÿe no nä konohiki e hoʻohana i ka diagnose ma mua infarction, lāʻau kū-infarction, myocardial ischemia, a me ka hoʻoʻino hou.

Ma ka hapanui o na hihia, he Akä hope paha ka gadolinium - hoomakaukau gadopentetat dimeglumine (gadopentetate dimeglumine).

MRI i nā hualoaʻa ma ka cardiology hiki ai iā mākou, e hooholo i ka nā kaʻa mokulele o ka hana ma hope o ka naau hoouka me kiʻekiʻe miomio. Ma ke kālailai hoʻololi i loko o nā nā'aʻaʻa o ka naau, e mea hiki ke pololei kau kaua kipi ma muli o ka nele i ke koko lako (ischemia) loli ma ka ventricular paia. Ischemia hoʻonāukiukiʻana mai o'āno'ē hoemi ia. MRI apono 'i ka noiʻi i loko o au mamuli o ka nui o kēia mau loli, a hooholo ina paha i coronary artery holo alaʻokoʻa pakuiia auanei lakou. Inā myocardial wahi hoʻonui hoonuiia dala o ka gadolinium, e Hōʻike irreversible necrotic loli i loko o ka naʻau'aʻaʻa. CABGʻoki kino ke hoʻihoʻi koko, piliwaiwai i ka wahi koko mau. Akā, inā 'oe i necrosis,ʻoki kino e e haawi aku i ka makemake hopena, ka hana ka hoʻokali kūpono' mea kaumaha ma luna o ke kino. Naʻe, i ka wa aole mea ole necrosis, CABG hoola i ka hoʻomanawanui ka naau. No keia kumu, cardiac MRI Radio nui i kūlana i kamaʻilio cardiac pilikia.

I ka hoʻohālike me ka echocardiography a MRI, positron ea puka tomography, e mea hiki ke kamailio e pili ana i kela ikaikaʻaoʻaoʻume mākenēki resonance kiʻi: ka hoʻomāhuahua o gadoliniumʻo ia ka mea hiki ke huai ae me ka kiʻekiʻe pololei ole-viable Hoʻohana a me viable myocardium aia i loko o ka Muscle'aʻaʻa o ka naau paia.

MRI o ka naau: e lawe mai nā kaʻina hana

I ka laulā o ka MRI nakeke o ka hoʻomanawanui moe motionless me ka noi degrade kiʻi e like ai. No ka mea lōʻihi like 'ole o ke kaʻina hana hiki ke lawe anywhere mai 30 minuke i 90 minuke. Office kahi e ikea ai, ua pono ho'āʻia a me ventilated. Ma ke ana o ka 'inikua limahana ua koi' ia e hōʻoia i ka oluolu ana o ka hoʻomanawanui.

Contraindication i MRI hana hiki ke kukuluia e kekahi pacemaker, metala implants, a me ka 'ē aʻe like' ikamu.

Ke koena eʻAʻole pono kuikawa aʻo e hana cardiac MRI.
