Mafunso 6 Omwe Amafunsidwa Kawirikawiri Okhudza Mayeso a MRI

Ngati munthu wavulala pamene akuchita masewera olimbitsa thupi, dokotala wawo adzalamula kuti aone X-ray. MRI ingafunike ngati ili yoopsa kwambiri. Komabe, odwala ena amakhala ndi nkhawa kwambiri moti amafunikira munthu amene angawafotokozere mwatsatanetsatane zomwe mtundu uwu wa mayeso umaphatikizapo komanso zomwe angayembekezere.

N’zomveka kuti vuto lililonse la zaumoyo lingayambitse nkhawa komanso kupsinjika maganizo. Kutengera ndi momwe zinthu zilili, gulu losamalira wodwalayo likhoza kuyamba ndi kujambula zithunzi monga X-ray, mayeso osapweteka omwe amasonkhanitsa zithunzi za ziwalo m’thupi. Ngati pakufunika kudziwa zambiri - makamaka zokhudza ziwalo zamkati kapena minofu yofewa - MRI ingafunike.

MRI, kapena magnetic resonance imaging, ndi njira yojambulira yachipatala yomwe imagwiritsa ntchito mphamvu zamaginito ndi mafunde a wailesi kuti ipange zithunzi zatsatanetsatane za ziwalo ndi minofu m'thupi.

Anthu nthawi zambiri amakhala ndi kusamvetsetsana ndi mafunso ambiri akamalandira MRI. Nawa mafunso asanu apamwamba omwe anthu amafunsa pafupifupi tsiku lililonse. Tikukhulupirira kuti izi zikuthandizani kumvetsetsa zomwe mungayembekezere mukalandira mayeso a radiology.

1. Kodi izi zimatenga nthawi yayitali bwanji?

Pali zifukwa zambiri zomwe mayeso a MRI amatenga nthawi yayitali kuposa ma X-ray ndi ma CT scan. Choyamba, ma electromagnetism amagwiritsidwa ntchito popanga zithunzi izi. Titha kuchita mwachangu ngati matupi athu ali ndi maginito. Kachiwiri, cholinga chake ndikupanga zithunzi zabwino kwambiri, zomwe zikutanthauza kuti nthawi yochulukirapo mkati mwa scanner. Koma kumveka bwino kumatanthauza kuti akatswiri a radiology nthawi zambiri amatha kuzindikira matenda m'zithunzi zathu kuposa m'zithunzi zochokera ku malo ena.

2. N’chifukwa chiyani odwala amayenera kusintha zovala zanga ndi kuchotsa zodzikongoletsera zanga?

Makina a MRI ali ndi maginito opititsa patsogolo mphamvu zomwe zimapangitsa kutentha ndikupanga mphamvu yamphamvu kwambiri ya maginito, kotero ndikofunikira kukhala otetezeka. Maginito amatha kukoka zinthu zachitsulo, kapena zomwe zili ndi chitsulo, kulowa mu makinawo ndi mphamvu zambiri. Izi zingayambitsenso makinawo kuzungulira ndi kuzungulira ndi mizere ya maginito. Zinthu zopanda chitsulo monga aluminiyamu kapena mkuwa zimapanga kutentha zikalowa mu scanner, zomwe zingayambitse kutentha. Pakhala nthawi zina pomwe zovala zayatsidwa. Pofuna kupewa mavuto aliwonse awa, tikupempha odwala onse kuti avale zovala zovomerezeka kuchipatala ndikuchotsa zodzikongoletsera zonse ndi zida zilizonse monga mafoni am'manja, zothandizira kumva ndi zinthu zina m'thupi.

3. Dokotala wanga akuti choyikamo changa chili bwino. N’chifukwa chiyani chidziwitso changa chikufunika?

Kuti wodwala aliyense ndi katswiri akhale otetezeka, ndikofunikira kudziwa ngati zipangizo zina, monga pacemakers, stimulators, clips, kapena coils, zaikidwa m'thupi. Zipangizozi nthawi zambiri zimabwera ndi majenereta kapena mabatire, kotero chitetezo chowonjezera chimafunika kuti makinawo asasokonezedwe, kuthekera kwake kupeza zithunzi zolondola kwambiri, kapena kuthekera kwake kukutetezani. Tikadziwa kuti wodwala ali ndi chipangizo choyikidwa, tiyenera kusintha momwe scanner imagwirira ntchito motsatira malangizo a wopanga. Makamaka, tiyenera kuonetsetsa kuti odwala akhoza kuyikidwa bwino mkati mwa scanner ya 1.5 Tesla (1.5T) kapena scanner ya 3 Tesla (3T). Tesla ndi gawo loyezera mphamvu ya maginito. Ma scanner a MRI a Mayo Clinic amapezeka mu mphamvu za 1.5T, 3T, ndi 7 Tesla (7T). Madokotala ayeneranso kuwonetsetsa kuti chipangizocho chili mu "MRI safe" mode asanayambe scan. Ngati wodwala alowa mu MRI popanda kutsatira njira zonse zodzitetezera, zidazo zitha kuwonongeka kapena kupsa kungachitike kapena wodwalayo angagwe ndi mantha.

4. Kodi wodwalayo adzalandira jakisoni wotani, ngati alipo?

Odwala ambiri amalandira jakisoni wa contrast media, womwe umagwiritsidwa ntchito kuthandiza kupititsa patsogolo kujambula zithunzi. (Contrast media nthawi zambiri imalowetsedwa m'thupi la wodwalayo pogwiritsa ntchitojekeseni wa media wotsutsana ndi kuthamanga kwambiriMitundu ya injector yosiyanitsa zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi mongaInjektara imodzi ya CT, Injector ya mutu wa CT iwiri, Jakisoni wa MRIndiInjector ya kuthamanga kwa magazi (Angiography)) Jakisoni nthawi zambiri amaperekedwa kudzera m'mitsempha ndipo sangayambitse mavuto kapena kupsa. Kuphatikiza apo, kutengera mayeso omwe achitika, odwala ena angalandire jakisoni wa mankhwala otchedwa glucagon, omwe angathandize kuchepetsa kuyenda kwa mimba kuti zithunzi zolondola zitha kujambulidwa.

5. Ndimaopa claustrophobia. Nanga bwanji ngati ndikumva kuti sindili bwino kapena sindikumva bwino panthawi ya mayeso?

Pali kamera mkati mwa chubu cha MRI kuti katswiriyo athe kuyang'anira wodwalayo. Kuphatikiza apo, odwala amavala mahedifoni kuti athe kumva malangizo ndikulankhulana ndi akatswiri. Ngati odwala akumva kusasangalala kapena kuda nkhawa nthawi iliyonse panthawi yoyezetsa, amatha kulankhula ndipo ogwira ntchito adzayesa kuwathandiza. Kuphatikiza apo, kwa odwala ena, mankhwala oletsa ululu angagwiritsidwe ntchito. Ngati wodwala sangathe kuchitidwa MRI, katswiri wa radiology ndi dokotala wotsogolera wodwalayo adzakambirana kuti adziwe ngati mayeso ena ndi oyenera.

6. Kaya zili zofunika mtundu wa malo omwe akupita kuti akawonedwe ndi MRI scan.

Pali mitundu yosiyanasiyana ya ma scanner, omwe amatha kusiyana malinga ndi mphamvu ya maginito yomwe imagwiritsidwa ntchito kusonkhanitsa zithunzi. Nthawi zambiri timagwiritsa ntchito ma scanner a 1.5T, 3T ndi 7T. Kutengera ndi kufunikira kwa wodwalayo komanso gawo la thupi lomwe likujambulidwa (monga ubongo, msana, mimba, bondo), scanner inayake ingakhale yoyenera bwino kuti ione bwino momwe wodwalayo alili ndi kudziwa matenda.

LnkMed ndi kampani yopereka zinthu ndi ntchito za radiology m'makampani azachipatala. Ma syringe opangidwa ndi kupangidwa ndi kampani yathu, kuphatikizapoInjektara imodzi ya CT,Injector ya mutu wa CT iwiri,Jakisoni wa MRIndiangiography contrast media injector, zagulitsidwa ku mayunitsi pafupifupi 300 kunyumba ndi kunja, ndipo zayamikiridwa ndi makasitomala. Nthawi yomweyo, LnkMed imaperekanso singano ndi machubu othandizira monga zinthu zogwiritsidwa ntchito pamitundu iyi: Medrad, Guerbet, Nemoto, ndi zina zotero, komanso malo olumikizirana mpweya wabwino, zowunikira ferromagnetic ndi zinthu zina zamankhwala. LnkMed nthawi zonse imakhulupirira kuti khalidwe ndiye maziko a chitukuko, ndipo yakhala ikugwira ntchito molimbika kuti ipatse makasitomala zinthu ndi ntchito zapamwamba. Ngati mukufuna zinthu zojambulira zamankhwala, takulandirani kuti mulankhule kapena kukambirana nafe.
