Kodi Wodwala Wamba Ayenera Kudziwa Chiyani Zokhudza Kuyezetsa kwa MRI?

Tikapita kuchipatala, dokotala adzatipatsa mayeso ena ojambulira zithunzi malinga ndi kufunikira kwa vutolo, monga MRI, CT, X-ray film kapena Ultrasound. MRI, magnetic resonance imaging, yotchedwa "nuclear magnetic", tiyeni tiwone zomwe anthu wamba ayenera kudziwa za MRI.

Kodi pali radiation mu MRI?

Pakadali pano, MRI ndiyo dipatimenti yokhayo ya radiology yopanda zinthu zoyezera radiation, okalamba, ana ndi amayi apakati angathe kuchita izi. Ngakhale X-ray ndi CT zimadziwika kuti zili ndi radiation, MRI ndi yotetezeka.

Nchifukwa chiyani sindingathe kunyamula zinthu zachitsulo ndi zamaginito pathupi langa panthawi ya MRI?

Thupi lalikulu la makina a MRI lingayerekezeredwe ndi maginito akuluakulu. Kaya makinawo atsegulidwa kapena ayi, mphamvu yaikulu ya maginito ndi mphamvu yaikulu ya maginito ya makinawo zidzakhalapo nthawi zonse. Zinthu zonse zachitsulo zomwe zili ndi chitsulo, monga zikhomo za tsitsi, ndalama, malamba, mapini, mawotchi, mikanda, ndolo ndi zodzikongoletsera zina ndi zovala, n'zosavuta kuzimeza. Zinthu zamaginito, monga makadi a maginito, makadi a IC, makina oletsa kupweteka, AIDS yomvera, mafoni am'manja ndi zida zina zamagetsi, zimawonongeka mosavuta ndi maginito. Chifukwa chake, anthu ena omwe ali nawo limodzi ndi achibale sayenera kulowa mchipinda chowunikira popanda chilolezo cha ogwira ntchito zachipatala; Ngati wodwalayo ayenera kutsagana ndi womuperekeza, ayenera kuvomerezedwa ndi ogwira ntchito zachipatala ndikukonzekera malinga ndi zofunikira za ogwira ntchito zachipatala, monga kusabweretsa mafoni am'manja, makiyi, zikwama zandalama ndi zida zamagetsi mchipinda chowunikira.

Zinthu zachitsulo ndi zinthu zamaginito zomwe zimayamwa ndi makina a MRI zidzakhala ndi zotsatirapo zoopsa: choyamba, khalidwe la chithunzi lidzakhudzidwa kwambiri, ndipo chachiwiri, thupi la munthu lidzavulala mosavuta ndipo makinawo adzawonongeka panthawi yowunikira. Ngati choyikamo chachitsulo m'thupi la munthu chilowetsedwa mu mphamvu yamaginito, mphamvu yamaginito yamphamvu ingapangitse kutentha kwa choyikamo kukwera, kutentha kwambiri komanso kuwonongeka, ndipo malo a choyikamo m'thupi la wodwalayo angasinthe, komanso kubweretsa kutentha kosiyanasiyana pamalo a choyikamo cha wodwalayo, komwe kungakhale koopsa ngati kutentha kwa digiri yachitatu.

Kodi MRI ingagwiritsidwe ntchito ndi mano opangidwa ndi mano?

Anthu ambiri omwe ali ndi mano opangidwa ndi chitsulo amada nkhawa kuti sangathe kuchitidwa MRI, makamaka okalamba. Ndipotu, pali mitundu yambiri ya mano opangidwa ndi chitsulo, monga mano opangidwa ndi chitsulo ndi titaniyamu. Ngati mano opangidwa ndi chitsulo si aloyi yachitsulo kapena titaniyamu, sizikhudza kwambiri MRI. Ngati mano opangidwa ndi chitsulo kapena maginito, ndi bwino kuchotsa mano opangidwa ndi chitsulo kaye, chifukwa n'zosavuta kusuntha mu mphamvu ya maginito ndipo zimakhudza ubwino wa kuwunika, zomwe zidzawopsezenso chitetezo cha odwala; Ngati ndi mano opangidwa ndi chitsulo, musadandaule kwambiri, chifukwa mano opangidwa ndi chitsulo okha sadzasuntha, zinthu zomwe zimachokera zimakhala zazing'ono. Mwachitsanzo, kuti mupange MRI ya ubongo, mano opangidwa ndi chitsulo amakhudza filimu (ndiye chithunzi) chomwe chatengedwa, ndipo kukhudzako ndi kochepa, nthawi zambiri sikukhudza matenda. Komabe, ngati gawo la kafukufuku lili pamalo a mano opangidwa ndi chitsulo, limakhudzabe filimuyo kwambiri, ndipo vutoli ndi lochepa, ndipo ogwira ntchito zachipatala ayenera kufunsidwa pamalopo. Musasiye kudya chifukwa choopa kutsamwa, chifukwa simuchita MRI chifukwa muli ndi mano okhazikika.

N’chifukwa chiyani ndimadzimva kutentha komanso thukuta panthawi ya MRI?

Monga tonse tikudziwa, mafoni a m'manja amakhala otentha pang'ono kapena otentha kwambiri akaimba foni, kufufuza pa intaneti kapena kusewera masewera kwa nthawi yayitali, zomwe zimachitika chifukwa cha kulandira ndi kutumiza zizindikiro pafupipafupi zomwe zimachitika ndi mafoni a m'manja, ndipo anthu omwe akuchitidwa MRI ali ngati mafoni a m'manja. Anthu akapitiliza kulandira zizindikiro za RF, mphamvuyo imatulutsidwa kutentha, kotero amamva kutentha pang'ono ndikuchotsa kutentha kudzera mu thukuta. Chifukwa chake, thukuta panthawi ya MRI ndi lachibadwa.

Nchifukwa chiyani phokoso limakhala lalikulu panthawi ya MRI?

Makina a MRI ali ndi gawo lamkati lotchedwa "gradient coil", lomwe limapanga mphamvu yosinthasintha nthawi zonse, ndipo kusintha kwakuthwa kwa mphamvu kumapangitsa kuti coil igwedezeke kwambiri, zomwe zimapangitsa phokoso.

Pakadali pano, phokoso lomwe limayambitsidwa ndi zida za MRI m'zipatala nthawi zambiri limakhala ma decibel 65 mpaka 95, ndipo phokosoli lingayambitse kuwonongeka kwa kumva kwa odwala akalandira MRI popanda zida zotetezera makutu. Ngati ma earplugs agwiritsidwa ntchito bwino, phokosolo likhoza kuchepetsedwa kufika pa ma decibel 10 mpaka 30, ndipo nthawi zambiri palibe kuwonongeka kwa kumva.

Kodi mukufunika "kujambula" MRI?

Pali mtundu wa mayeso a MRI otchedwa enhanced scans. Kujambula kwa MRI kowonjezereka kumafuna jakisoni wa mankhwala omwe akatswiri a radiology amatcha "contrast agent," makamaka contrast agent yokhala ndi "gadolinium." Ngakhale kuti kuchuluka kwa zotsatira zoyipa ndi gadolinium contrast agents ndi kochepa, kuyambira 1.5% mpaka 2.5%, sikuyenera kunyalanyazidwa.

Zotsatira zoyipa za gadolinium contrast agents zikuphatikizapo chizungulire, mutu wosakhalitsa, nseru, kusanza, ziphuphu, kusokonezeka kwa kukoma, ndi kuzizira pamalo obayira jakisoni. Kuchuluka kwa zotsatira zoyipa kwambiri n'kochepa kwambiri ndipo kungawonekere ngati kupuma movutikira, kuchepa kwa kuthamanga kwa magazi, mphumu ya bronchial, kutupa kwa m'mapapo, komanso ngakhale imfa.

Odwala ambiri omwe ali ndi vuto lalikulu la impso anali ndi mbiri ya matenda opuma kapena matenda enaake. Kwa odwala omwe ali ndi vuto la impso, mankhwala oletsa gadolinium amatha kuwonjezera chiopsezo cha matenda a impso. Chifukwa chake, mankhwala oletsa gadolinium amaletsedwa kwa anthu omwe ali ndi vuto lalikulu la impso. Ngati simukumva bwino panthawi yoyezetsa MRI kapena mutatha, dziwitsani ogwira ntchito zachipatala, imwani madzi ambiri, ndikupumula kwa mphindi 30 musanachoke.

LnkMedImayang'ana kwambiri pakupanga, kupanga ndi kupanga ma injectcors okhala ndi mphamvu yotsika komanso zinthu zina zamankhwala zoyenera ma injector odziwika bwino. Mpaka pano, LnkMed yatulutsa zinthu 10 zomwe zili ndi ufulu wodziyimira pawokha wazinthu zanzeru pamsika, kuphatikizaInjektara imodzi ya CT, Injector ya mutu wa CT iwiri, jekeseni ya DSA, Jakisoni wa MRI, ndi sirinji yapaipi ya maola 12 yogwirizana ndi zinthu zina zapamwamba zapakhomo, zonseChiyerekezo cha magwiridwe antchito chafika pamlingo wapamwamba padziko lonse lapansi, ndipo zinthuzo zagulitsidwa ku Australia, Thailand, Brazil, ndi mayiko ena, Zimbabwe ndi mayiko ena ambiri.LnkMed ipitiliza kupereka zinthu zapamwamba kwambiri pa ntchito yojambula zithunzi zachipatala, ndipo imayesetsa kukonza ubwino wa zithunzi ndi thanzi la odwala. Funso lanu ndi lolandiridwa.
