CT ndi MRI zimagwiritsa ntchito njira zosiyanasiyana kuti zisonyeze zinthu zosiyanasiyana - komanso sizili "zabwino" kuposa zina.
Kuvulala kwina kapena mikhalidwe imatha kuwonedwa ndi maso. Ena amafuna kumvetsetsa kozama.
Ngati wothandizira zaumoyo wanu akukayikira kuti ali ndi vuto monga kutuluka magazi mkati, chotupa, kapena kuwonongeka kwa minofu, akhoza kuitanitsa CT scan kapena MRI.
Kusankha kugwiritsa ntchito CT scan kapena MRI kuli kwa wothandizira zaumoyo wanu, makamaka malinga ndi zomwe akuganiza kuti adzapeza.
Kodi CT ndi MRI zimagwira ntchito bwanji? Ndi iti yomwe ili yabwino kwa chiyani? Tiyeni tione bwinobwino.
CT scan, yochepa pa computed tomography scan, imagwira ntchito ngati makina a 3D X-ray. CT scanner imagwiritsa ntchito X-ray yomwe imadutsa wodwala kupita ku detector pamene ikuzungulira wodwalayo. Imajambula zithunzi zambiri, zomwe kompyuta imasonkhanitsa kuti ipange chithunzi cha 3D cha wodwalayo. Zithunzizi zimatha kusinthidwa m'njira zosiyanasiyana kuti mupeze malingaliro amkati mwa thupi.
X-ray yachikhalidwe imatha kupatsa wothandizira wanu mawonekedwe amodzi pamalo omwe anali zithunzi. Ndi chithunzi chokhazikika.
Koma mutha kuyang'ana zithunzi za CT kuti muwone momwe mbalame imawonera malo omwe adajambulidwa. Kapena kuzungulira kuti muyang'ane kuchokera kutsogolo kupita kumbuyo kapena mbali ndi mbali. Mukhoza kuyang'ana kunja kwa dera. Kapena mawonedwe mkati mkati mwa gawo la thupi lomwe linajambulidwa.
CT Scan: Zimawoneka bwanji?
Kupeza CT scan kuyenera kukhala njira yachangu komanso yopanda ululu. Mumagona patebulo lomwe limadutsa pang'onopang'ono pa scanner ya mphete. Kutengera ndi zomwe dokotala akukufunirani, mungafunikenso utoto wosiyanitsa ndi mtsempha. Kujambula kulikonse kumatenga nthawi yosakwana miniti imodzi.
CT scan: ndi chiyani?
Chifukwa makina a CT scanner amagwiritsa ntchito X-ray, amatha kusonyeza zinthu zofanana ndi X-ray, koma molondola kwambiri. X-ray ndi mawonekedwe athyathyathya a malo ojambulira, pomwe CT imatha kupereka chithunzi chokwanira komanso chozama.
Ma CT scans amagwiritsidwa ntchito poyang'ana zinthu monga: Mafupa., Miyala, Magazi, Ziwalo, Mapapo, Gawo la Khansa, Zadzidzidzi za m'mimba.
Ma CT scans angagwiritsidwenso ntchito kuyang'ana zinthu zomwe MRI singathe kuziwona bwino, monga mapapo, magazi, ndi matumbo.
CT scan: Zowopsa zomwe zingachitike
Chodetsa nkhawa chachikulu chomwe anthu ena amakhala nacho ndi ma CT scan (ndi ma X-ray pankhaniyi) ndi kuthekera kwa kuyatsidwa kwa radiation.
Akatswiri ena anena kuti ma radiation ya ionizing opangidwa ndi makina ojambulira a CT angawonjezere pang'ono chiopsezo cha khansa mwa anthu ena. Koma kuopsa kwake kumatsutsana. Bungwe la Food and Drug Administration linati malinga ndi zimene asayansi akudziwa panopa, kuopsa kwa khansa yochokera ku radiation ya CT “sikudziwika bwinobwino.”
Komabe, chifukwa cha kuopsa kwa ma radiation a CT, amayi oyembekezera nthawi zambiri sali oyenerera CT scan pokhapokha ngati kuli kofunikira.
Nthawi zina, othandizira azaumoyo angasankhe kugwiritsa ntchito MRI m'malo mwa CT kuti achepetse chiopsezo cha radiation. Izi ndizowona makamaka kwa anthu omwe ali ndi thanzi lomwe limafunikira kujambulidwa kangapo kwa nthawi yayitali.
MRI
MRI imayimira magnetic resonance Imaging. Mwachidule, MRI imagwiritsa ntchito maginito ndi mafunde a wailesi kuti apange zithunzi mkati mwa thupi lanu.
Njira yeniyeni yomwe imagwirira ntchito imaphatikizapo phunziro lalitali la physics. Koma mwachidule, zili ngati izi: Matupi athu amakhala ndi madzi ambiri, omwe ndi H20. H mu H20 imayimira hydrogen. Hydrogen ili ndi ma protoni - tinthu tating'ono tambiri. Nthawi zambiri, ma protoni awa amazungulira mbali zosiyanasiyana. Koma akakumana ndi maginito, monganso mumakina a MRI, mapulotoni amenewa amakokedwa ku maginito n’kuyamba kufola.
MRI: Zili bwanji?
MRI ndi makina a tubular. Kujambula kwa MRI kumatenga pafupifupi mphindi 30 mpaka 50, ndipo muyenera kukhala chete panthawiyi. Makinawa amatha kukhala mokweza kwambiri, ndipo anthu ena angapindule povala zotsekera m’makutu kapena kugwiritsa ntchito mahedifoni kuti amvetsere nyimbo akamajambula. Kutengera ndi zosowa za omwe akukupatsani, atha kugwiritsa ntchito utoto wosiyanitsa m'mitsempha.
MRI: ndi chiyani?
MRI ndi yabwino kwambiri kusiyanitsa pakati pa minofu. Mwachitsanzo, opereka chithandizo amatha kugwiritsa ntchito thupi lonse la CT kuyang'ana zotupa. Kenako, MRI imachitidwa kuti imvetse bwino misa iliyonse yomwe imapezeka pa CT.
Wothandizira wanu angagwiritsenso ntchito MRI kuti ayang'ane kuwonongeka kwa mgwirizano ndi kuwonongeka kwa mitsempha.
Mitsempha ina imatha kuwonedwa ndi MRI, ndipo mukhoza kuona ngati pali kuwonongeka kapena kutupa kwa mitsempha m'madera ena a thupi. Sitingathe kuwona mitsempha mwachindunji pa CT P scan. Pa CT, tikhoza kuona fupa lozungulira mitsempha kapena minofu yozungulira mitsempha kuti tiwone ngati ili ndi zotsatira pa malo omwe timayembekezera kuti mitsempha ikhale. Koma poyang'ana mwachindunji mitsempha, MRI ndi mayeso abwinoko.
Ma MRIs sali abwino kwambiri poyang'ana zinthu zina, monga mafupa, magazi, mapapo ndi matumbo. Kumbukirani kuti MRI imadalira mbali ina pakugwiritsa ntchito maginito kuti iwononge haidrojeni m'madzi m'thupi. Zotsatira zake, zinthu zowirira monga miyala ya impso ndi mafupa sizimawonekera. Ngakhalenso chirichonse chomwe chadzazidwa ndi mpweya, monga mapapo anu.
MRI: Zowopsa zomwe zingatheke
Ngakhale MRI ikhoza kukhala njira yabwino yowonera zinthu zina m'thupi, si za aliyense.
Ngati muli ndi mitundu ina yazitsulo m'thupi lanu, MRI siingakhoze kuchitidwa. Izi ndichifukwa choti MRI kwenikweni ndi maginito, motero imatha kusokoneza zitsulo zina. Izi zikuphatikizapo ma pacemaker, defibrillators kapena shunt zipangizo.
Zitsulo monga zolowa m'malo olowa nthawi zambiri zimakhala zotetezedwa ndi MR. Koma musanapeze MRI scan, onetsetsani kuti wothandizira akudziwa zitsulo zilizonse m'thupi lanu.
Kuonjezera apo, kuyesa kwa MRI kumafuna kuti mukhale chete kwa nthawi, zomwe anthu ena sangathe kuzilekerera. Kwa ena, kutsekedwa kwa makina a MRI kungayambitse nkhawa kapena claustrophobia, zomwe zimapangitsa kujambula kukhala kovuta kwambiri.
Kodi imodzi yabwino kuposa inzake?
CT ndi MRI sizili bwino nthawi zonse, ndi nkhani ya zomwe mukuyang'ana komanso momwe mumalekerera zonsezi. Nthawi zambiri, anthu amaganiza kuti wina ndi wabwino kuposa wina. Koma zimatengera funso la dokotala wanu.
Mfundo yofunika kwambiri: Kaya dokotala wanu akulamulani CT kapena MRI, cholinga chake ndi kumvetsa zomwe zikuchitika m'thupi lanu kuti akupatseni chithandizo chabwino kwambiri.

Monga tonse tikudziwira, chitukuko cha makampani opanga zithunzi zachipatala sichingasiyanitsidwe ndi chitukuko cha zida zachipatala - majekeseni osiyanitsa ndi mankhwala omwe amawathandiza - omwe amagwiritsidwa ntchito kwambiri pa ntchitoyi. Ku China, komwe kumadziwika chifukwa chamakampani opanga zinthu, pali opanga ambiri otchuka kunyumba ndi kunja chifukwa chopanga zida zofananira zamankhwala, kuphatikizaLnkMed. Chiyambireni kukhazikitsidwa kwake, LnkMed yakhala ikuyang'ana kwambiri pa majekeseni ophatikizika kwambiri. Gulu la engineering la LnkMed limatsogozedwa ndi Ph.D. ali ndi zaka zopitilira khumi ndipo ali wotanganidwa kwambiri ndi kafukufuku ndi chitukuko. Motsogozedwa ndi iye, aCT single head injector,CT double mutu jekeseni,Injector yofananira ya MRI,ndiAngiography high-pressure jekeseni wothandizirazidapangidwa ndi izi: thupi lolimba komanso lolumikizana, mawonekedwe osavuta komanso anzeru ogwirira ntchito, ntchito zonse, chitetezo chokwanira, komanso kapangidwe kolimba. Tithanso kupereka majakisoni ndi machubu omwe amagwirizana ndi ma jakisoni otchuka a CT,MRI,DSA Ndi malingaliro awo owona komanso mphamvu zamaluso, onse ogwira ntchito ku LnkMed akukuitanani mowona mtima kuti mubwere kudzayendera limodzi misika yambiri.
