Sinus MRI scan

Qhov sib nqus resonance duab (MRI) ntawm lub nqus tau tsim cov duab ntxaws ntawm cov huab cua nyob hauv thaj chaw pob txha taub hau.

Cov chaw no hu ua cov hlab ntshav. Qhov kev kuaj no yog qhov tsis yog.

MRI siv cov hlau nplaum muaj zog thiab xov tooj cua vuam siv hluav taws xob. Cov phiajcim los ntawm cov khoom sib nqus tau rub tawm ntawm koj lub cev thiab raug xa mus rau lub khoos phis tawm. Muaj, lawv tau hloov mus ua cov duab. Hom sib txawv ntawm cov ntaub so ntswg xa rov qab cov cim.

Ib leeg MRI cov duab yog hu ua cov hlais. Cov duab tuaj yeem khaws cia rau hauv computer lossis luam tawm ntawm zaj duab xis. Ib qho kev xeem yuav tsim tau ntau pua lossis qee zaum ntau pua tus duab.

Tej zaum yuav kom koj hnav lub tsho tshaj sab hauv tsev kho mob lossis khaub ncaws yam tsis muaj khawm hlau lossis zippers (xws li cov hws lossis lub tsho loj). Qee hom hlau tuaj yeem ua rau cov duab zim zuag.

Koj yuav tau pw ntawm lub rooj nqaim, uas swb rau hauv cov ntsuas qhov zoo li lub qhov.

Cov cuab yeej me me, hu ua coils, muab tso nyob ib ncig ntawm lub taub hau. Cov cuab yeej siv no pab txhim kho cov duab zoo.

Qee qhov kev xeem yuav tsum muaj xim xeb tshwj xeeb (sib piv). Qhov zas xim feem ntau yog muab ua ntej sim los ntawm txoj hlab ntshav (IV) hauv koj txhais tes lossis caj npab. Zas yuav pab cov kws ntsuas hluav taws xob pom qee thaj chaw kom pom tseeb.

Thaum lub sij hawm MRI, tus neeg siv lub tshuab yuav saib xyuas koj los ntawm lwm chav. Qhov kev kuaj mob feem ntau kav 30 feeb, tab sis yuav siv sijhawm ntev dua.

Ua ntej kev sim, qhia tus kws ntsuas hluav taws xob yog tias koj muaj teeb meem lub raum. Qhov no tej zaum yuav cuam tshuam rau qhov koj tuaj yeem muaj qhov sib txawv ntawm IV.

Yog tias koj ntshai tsam chaw kaw (muaj claustrophobia), qhia koj tus kws kho mob ua ntej kev kuaj mob. Koj yuav tau muab tshuaj kom pab koj tsaug zog thiab tsis ntxhov siab. Koj tus kws kho mob kuj tseem yuav pom zoo MRI "qhib", hauv lub tshuab kom tsis ze ntawm lub cev.

Cov teb muaj zog loj heev uas tsim thaum lub MRI tuaj yeem cuam tshuam nrog cov ntsuas nrawm thiab lwm yam kev cog hniav. Cov neeg uas feem ntau mob plawv dhia tsis tuaj yeem muaj MRI thiab yuav tsum tsis txhob nkag mus hauv thaj chaw MRI. Qee qhov ua kom qeeb qeeb dua tau ua uas muaj kev nyab xeeb nrog MRI. Koj yuav tsum paub meej nrog koj tus kws kho mob yog tias koj lub ntsuas phoo ua kom muaj kev nyab xeeb hauv MRI.

Koj tuaj yeem tsis muaj MRI yog tias koj muaj ib qho ntawm cov khoom siv hlau hauv qab no hauv koj lub cev:

• Hlwb aneurysm txiav
• Qee yam ntawm cov khoom cua plawv tus kheej
• Lub plawv defibrillator los yog ua pa nplawm
• Pob ntseg hauv (cochlear) kev cog hniav hauv
• Nyuam qhuav tso cov pob qij txha txuas
• Qee hom vascular stents
• Kev kho mob twj

Qhia rau koj tus kws kho mob yog tias koj muaj ib qho ntawm cov khoom siv no thaum teem caij sim, yog li cov hlau ntawm hom yuav raug txiav txim siab.

Ua ntej MRI, cov neeg ua haujlwm hlau lossis cov neeg uas tej zaum yuav tsum tau tsom rau cov hlau me me yuav tsum tau txais cov xaim hluav taws xob xoo hluav taws xob. Qhov no yog txhawm rau kuaj xyuas hlau hauv qhov muag.

Vim tias MRI muaj cov hlau nplaum, cov khoom siv hlau uas muaj cov khoom xws li cwjmem, hnab tshos, thiab cov tsom iav qhov muag yuav ya hla chav. Qhov no tuaj yeem ua rau txaus ntshai, yog li lawv tsis tso cai rau thaj chaw luam theej duab.

Lwm cov khoom siv hlau tsis tso cai rau hauv chav tsev:

• Cov khoom xws li cov hniav nyiaj hniav kub, watches, credit card, thiab khoom siv tau hnov ​​tau ua kom puas ntsoog.
• Pins, hairpins, hlau zippers, thiab cov khoom siv hlau zoo ib yam tuaj yeem cuam tshuam cov duab.
• Kev tshem hniav ua haujlwm yuav tsum tau coj tawm ua ntej lub scan xwb.

Kev kuaj MRI ua rau tsis muaj mob. Qee tus neeg yuav pib ntxhov siab sab hauv lub scanner. Yog tias koj muaj teeb meem dag tsis tseem ceeb lossis ntxhov siab, koj yuav tau muab tshuaj kom pab koj nyob ntsiag to (pw tsaug zog). Ntau dhau ntawm lub zog tuaj yeem plooj MRI cov duab thiab ua rau tsis raug.

Lub rooj yuav ua tau tawv lossis txias. Koj tuaj yeem thov kom pam vov lossis pam vov. Lub tshuab ua suab nrov nrov nrov thiab lub suab nrov thaum tig mus. Koj tuaj yeem hnav lub pob ntseg kom pab txo lub suab nrov.

Lub intercom nyob rau hauv chav tsev cia koj hais lus rau tus neeg ua haujlwm ntawm lub scanner txhua lub sijhawm. Qee qhov ntsuas MRI tau muaj TV thiab lub mloog pob ntseg tshwj xeeb los pab lub sijhawm.

Tsis muaj lub sijhawm rov qab, tsuas yog koj xav tau kev ua kom loog. Tom qab MRI scan, koj tuaj yeem rov qab koj li qub kev noj haus, ua si, thiab tshuaj.

Qhov kev sim no muab cov duab ntxaws ntxaws ntawm cov kev ua txhaum. Koj tus kws khomob yuav hais cov lus kuaj no yog koj muaj:

• Kev hnia tawm ntawm qhov ntswg qhov tsis zoo
• Qhov txawv txav nrhiav ntawm xoo hluav taws xob lossis duab qws qhov ntswg
• Lub caij yug ntawm cov txhaum
• Ua rau tsis hnov ​​tsw
• Txoj hlab pa qhov ntswg txhaws tsis zoo nrog kho
• Rov ua dua qhov ntswg ntshav (epistaxis)
• Cov cim ntawm kev raug mob rau thaj tsam sinus
• Tsis yoog taub hau
• Kev kuaj mob uas tsis tau txais kev mob uas ua tsis tau zoo dua nrog kev kho

Koj tus kws khomob yuav hais kom ua raws li no rau:

• Txiav txim siab yog tias qhov ntswg polyps tau kis mus dhau thaj chaw ntswg
• Kev ntsuas xyuas tus mob los yog qhaj
• Txheeb xyuas ib qhov loj lossis qog, nrog rau mob qog noj
• Npaj phais qhov ntswg ntshav lossis saib xyuas koj txoj kev kawm tom qab kev phais

Cov txiaj ntsig tau txiav txim siab ib txwm muaj yog tias cov plab hnyuv siab raum thiab cov qauv kuaj tau zoo li qub.

Txawv cov ntaub ntawv sib txawv xa rov qab sib txawv MRI cov cim. Cov nqaij zoo yuav xa rov qab lub suab txawv dua li mob qog nqaij.

Qhov ntsuas tsis zoo yuav yog vim:

• Mob cancer lossis qog
• Kab mob hauv cov pob txha ntawm qhov txhab (pob txha osteomyelitis)
• Kev kis mob ntawm cov ntaub so ntswg uas nyob ib ncig ntawm lub qhov muag (orbital cellulitis)
• Ncauj polyps
• Sinusitis - mob huam
• Mob Sinusitis - mob ntev

Tham nrog koj tus kws kho mob yog tias koj muaj lus nug thiab kev txhawj xeeb.

MRI siv tsis muaj hluav taws xob ionizing. Tsis muaj kev phiv los ntawm MRI tau qhia. Qhov feem ntau ntawm cov sib piv (zas xim) siv yog gadolinium. Nws muaj kev nyab xeeb heev. Ua xua rau cov xim no tsis tshua muaj tshwm sim. Tus neeg siv lub tshuab yuav saib xyuas koj lub plawv dhia thiab ua pa.

Tsis tshua muaj, cov neeg muaj lub raum tsis ua haujlwm lossis mob raum muaj peev xwm tsim kev tsis haum ntawm qhov sib piv (zas xim). Yog tias koj muaj teeb meem lub raum, nws yog qhov tseem ceeb uas yuav tau qhia rau MRI tus kws tshaj lij thiab koj tus kws kho mob ua ntej koj tau txais lub zas xim no.

MRI feem ntau tsis pom zoo rau cov xwm txheej mob hnyav, vim tias cov cuab yeej ua haujlwm thiab cov khoom siv pab cuam lub neej tsis tuaj yeem nkag mus rau thaj chaw thaij duab thiab kev soj ntsuam tuaj yeem siv sijhawm me ntsis.

Cov tib neeg tau raug mob nyob hauv MRI cov tshuab thaum lawv tsis tshem cov khoom hlau los ntawm lawv cov khaub ncaws lossis thaum lwm tus khoom hlau tau tso rau hauv chav los ntawm lwm tus.

Kev ntsuam xyuas uas yuav ua kom tsis muaj qhov qhov ntswg MRI muaj xws li:

• CT scan ntawm lub sinuses
• X-ray ntawm txoj kev ua txhaum

Txoj kev kuaj mob CT yuav tau zoo dua hauv cov xwm txheej ceev, vim nws sai dua thiab feem ntau muaj nyob hauv chav xwm txheej ceev.

Nco tseg: MRI tsis muaj txiaj ntsig zoo li CT hauv kev txhais lub cev ntawm lub qhov ntswg, thiab yog li ntawd tsis siv rau qhov kev xav tias mob siab mob siab.
