Tikamapita kuchipatala, dokotala adzatipatsa zoyezetsa zithunzi molingana ndi kufunikira kwa vutoli, monga MRI, CT, X-ray film kapena Ultrasound. MRI, imaging resonance imaging, yotchedwa "nuclear magnetic", tiyeni tiwone zomwe anthu wamba ayenera kudziwa za MRI.
Kodi pali ma radiation mu MRI?
Pakalipano, MRI ndi dipatimenti yokhayo ya radiology popanda zinthu zowunikira, okalamba, ana ndi amayi apakati angachite. Ngakhale X-ray ndi CT amadziwika kuti ali ndi ma radiation, MRI ndiyotetezeka.
Chifukwa chiyani sindingathe kunyamula zinthu zachitsulo ndi maginito pathupi langa panthawi ya MRI?
Thupi lalikulu la makina a MRI likhoza kufananizidwa ndi maginito aakulu. Ziribe kanthu kaya makina atsegulidwa kapena ayi, mphamvu yaikulu ya maginito ndi mphamvu yaikulu ya maginito ya makina idzakhalapo nthawi zonse. Zinthu zonse zachitsulo zomwe zili ndi chitsulo, monga zopangira tsitsi, ndalama, malamba, mapini, mawotchi, mikanda, ndolo ndi zodzikongoletsera ndi zovala zina, ndizosavuta kuyamwa. Zinthu zamaginito, monga makadi a maginito, IC makadi, makina owongolera pacemaker, AIDS yakumva, mafoni a m’manja ndi zipangizo zina zamagetsi, zimakhala ndi maginito kapena kuwonongeka mosavuta. Chifukwa chake, anthu ena otsagana nawo ndi achibale sayenera kulowa mchipinda chojambulira popanda chilolezo cha achipatala; Ngati wodwala akuyenera kuperekezedwa ndi woperekeza, ayenera kuvomerezana ndi ogwira ntchito zachipatala ndikukonzekereratu malinga ndi zofunikira za ogwira ntchito pachipatala, monga kusabweretsa mafoni am'manja, makiyi, zikwama zachikwama ndi zida zamagetsi m'chipinda chojambulira.
Zinthu zachitsulo ndi maginito zomwe zimayamwa ndi makina a MRI zidzakhala ndi zotsatira zoopsa: choyamba, khalidwe lachifanizo lidzakhudzidwa kwambiri, ndipo chachiwiri, thupi la munthu lidzavulazidwa mosavuta ndipo makinawo adzawonongeka panthawi yoyendera. Ngati chitsulo choyikapo m'thupi la munthu chikubweretsedwa ku mphamvu ya maginito, mphamvu ya maginito imatha kupangitsa kuti kutentha kwa thupi kuchuluke, kutenthedwa ndi kuwonongeka, ndipo malo a implants m'thupi la wodwalayo angasinthe, ndipo amatsogolera ku madigiri osiyanasiyana. kuyaka pamalo oikapo wodwalayo, komwe kumatha kukhala koopsa ngati kupsa kwa digiri yachitatu.
Kodi MRI ingachitidwe ndi mano?
Anthu ambiri okhala ndi mano amadandaula chifukwa cholephera kupeza MRI, makamaka okalamba. Kunena zowona, pali mitundu yambiri ya mano, monga mano osasunthika ndi osunthika. Ngati mano a mano sizitsulo kapena titaniyamu aloyi, alibe mphamvu pa MRI. Ngati mano ali ndi chitsulo kapena maginito zigawo zikuluzikulu, ndi bwino kuchotsa yogwira mano choyamba, chifukwa n'zosavuta kusuntha mu mphamvu maginito ndi kukhudza khalidwe anayendera, amenenso adzaika pangozi chitetezo cha odwala; Ngati ndi mano osasunthika, musadandaule kwambiri, chifukwa mano osasunthika okhawo sangasunthe, zomwe zimapangidwira zimakhala zazing'ono. Mwachitsanzo, kupanga MRI yaubongo, mano okhazikika amangokhudza filimuyo (ndiye kuti, chithunzi) chomwe chatengedwa, ndipo zotsatira zake zimakhala zazing'ono, nthawi zambiri sizikhudza matendawo. Komabe, ngati gawo la kafukufukuyo likupezeka pa malo a mano, limakhalabe ndi chikoka chachikulu pa filimuyi, ndipo izi ndizochepa, ndipo ogwira ntchito zachipatala ayenera kufunsidwa pazochitikazo. Osasiya kudya chifukwa choopa kutsamwitsidwa, chifukwa simupanga MRI chifukwa muli ndi mano opangira mano.
Chifukwa chiyani ndimamva kutentha komanso thukuta pa MRI?
Monga tonse tikudziwira, mafoni a m'manja adzakhala otentha pang'ono kapena otentha pambuyo poyimba mafoni, kufufuza intaneti kapena kusewera masewera kwa nthawi yaitali, zomwe zimachitika chifukwa cholandira ndi kufalitsa zizindikiro zomwe zimayambitsidwa ndi mafoni a m'manja, ndi anthu omwe akukumana ndi MRI. zili ngati mafoni am'manja. Anthu akapitiliza kulandira ma siginecha a RF, mphamvuyo imatulutsidwa pakutentha, motero amamva kutentha pang'ono ndikuchotsa kutentha kudzera mu thukuta. Choncho, kutuluka thukuta pa MRI n'kwachibadwa.
Nchifukwa chiyani pali phokoso lalikulu pa MRI?
Makina a MRI ali ndi gawo lamkati lotchedwa "gradient coil", lomwe limapanga kusintha kosasintha, ndipo kusintha kwakuthwa kwaposachedwa kumabweretsa kugwedezeka kwapamwamba kwa coil, komwe kumatulutsa phokoso.
Pakalipano, phokoso la zida za MRI m'zipatala nthawi zambiri zimakhala ma decibel 65 ~ 95, ndipo phokosoli likhoza kuwononga makutu a odwala pamene akulandira MRI popanda zipangizo zotetezera makutu. Zomangira m’makutu zikagwiritsiridwa ntchito bwino, phokosolo limatha kuchepetsedwa kufika pa ma decibel 10 mpaka 30, ndipo kaŵirikaŵiri sipamakhala kuwonongeka kwa makutu.
Kodi mukufuna "kuwombera" kwa MRI?
Pali kalasi ya mayeso mu MRI yotchedwa enhanced scans. Kujambula kowonjezera kwa MRI kumafuna jakisoni wamtsempha wamankhwala omwe akatswiri a radiology amawatcha "contrast agent," makamaka wosiyanitsa wokhala ndi "gadolinium." Ngakhale kuchuluka kwa zoyipa zomwe zimachitika ndi mankhwala a gadolinium ndizochepa, kuyambira 1.5% mpaka 2.5%, siziyenera kunyalanyazidwa.
Zotsatira zoyipa za mankhwala osiyanitsa a gadolinium ndi monga chizungulire, mutu kwanthawi yayitali, nseru, kusanza, zidzolo, kusokoneza kukoma, komanso kuzizira pamalo obaya jakisoni. Kuchuluka kwa zovuta zoyipa ndizochepa kwambiri ndipo kumatha kuwonetsedwa ngati kukomoka, kuchepa kwa magazi, mphumu ya bronchial, edema ya m'mapapo, ngakhale kufa.
Odwala ambiri omwe ali ndi vuto lalikulu anali ndi mbiri ya matenda opuma kapena matupi awo sagwirizana. Odwala omwe ali ndi vuto laimpso, gadolinium kusiyanitsa othandizira amatha kukulitsa chiwopsezo cha aimpso systemic fibrosis. Chifukwa chake, mankhwala osiyanitsa a gadolinium amaletsedwa mwa anthu omwe ali ndi vuto laimpso kwambiri. Ngati mukumva kuti simukumva bwino panthawi ya MRI kapena pambuyo pake, dziwitsani ogwira ntchito zachipatala, kumwa madzi ambiri, ndipo mupumule kwa mphindi 30 musananyamuke.
LnkMedimayang'ana pa chitukuko, kupanga ndi kupanga ma injetcors ophatikizika kwambiri komanso zogulitsira zamankhwala zoyenera majekeseni akuluakulu odziwika bwino. Mpaka pano, LnkMed yakhazikitsa zinthu 10 zokhala ndi ufulu wodziyimira pawokha wamsika pamsika, kuphatikizaCT injector imodzi, CT wapawiri mutu jekeseni, DSA injector, MRI jekeseni, ndi syringe ya chitoliro cha maola 12 ndi zinthu zina zapamwamba zapakhomo, zonseindex index yafika pagulu lapadziko lonse lapansi, ndipo zinthuzo zagulitsidwa ku Australia, Thailand, Brazil, ndi mayiko ena. Zimbabwe ndi mayiko ena ambiri.LnkMed idzapitirizabe kupereka mankhwala apamwamba kwambiri pazithunzi zachipatala, ndikuyesetsa kupititsa patsogolo chithunzithunzi ndi thanzi la odwala. Kufunsa kwanu ndikolandiridwa.
