Lymphoscintigraphy

Lymphoscintigraphy yog ib txoj kev siv duab tshwj xeeb uas siv los tshuaj xyuas lub cev lymphatic, uas ua lub luag haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob. Lub cev lymphatic suav nrog cov qog lymph, cov hlab ntsha lymph, thiab cov kua lymph, tag nrho cov no pab tiv thaiv kev kis kab mob thiab tshem tawm cov khoom pov tseg ntawm lub cev. Lymphoscintigraphy pab soj ntsuam lub cev no thiab kuaj mob uas cuam tshuam rau kev ntws thiab kev ua haujlwm ntawm lymph, suav nrog lymphedema, lymphatic blockages, thiab qee yam mob qog noj ntshav.

Lymphoscintigraphy yog dab tsi?

Lymphoscintigraphy yog ib hom kev siv tshuaj nuclear imaging uas siv me ntsis cov khoom siv radioactive (radiotracer) los pom cov kab mob lymphatic. Cov tshuaj radiotracer raug txhaj rau hauv ib qho chaw tshwj xeeb ntawm lub cev, thiab lub koob yees duab gamma raug siv los ntes cov duab thaum cov tshuaj mus ncig los ntawm cov hlab ntsha lymphatic thiab cov qog ntshav. Cov txheej txheem no tso cai rau cov kws kho mob saib xyuas seb cov kua lymphatic ntws li cas, txheeb xyuas cov kev thaiv lossis qhov tsis zoo, thiab soj ntsuam cov kev ntws lymphatic.

Tsis zoo li cov txheej txheem thaij duab ib txwm muaj xws li X-rays lossis CT scans, lymphoscintigraphy muab cov duab dynamic thiab functional ntawm lub cev lymphatic, ua rau nws yog ib qho cuab yeej muaj txiaj ntsig rau kev kuaj pom cov teeb meem xws li lymphedema (o vim yog kua dej), qog, lossis kab mob hauv cov qog ntshav.

Lymphoscintigraphy Ua Haujlwm Li Cas?

Thaum lub sijhawm ua cov txheej txheem lymphoscintigraphy, ib qho radiotracer (feem ntau yog ib qho tshuaj ua los ntawm technetium-99m thiab colloid lossis nanoparticle) raug txhaj rau hauv thaj chaw uas xav tau, feem ntau nyob ze ntawm qhov chaw uas xav tias muaj kev kis kab mob lossis qog nqaij hlav. Lub radiotracer raug nqa los ntawm lub cev lymphatic los ntawm cov kua dej lymph, thiab thaum nws txav mus, nws tso tawm gamma rays uas raug ntes los ntawm lub koob yees duab gamma.

Lub koob yees duab gamma kaw cov hluav taws xob uas lub tracer tso tawm, tsim cov duab ntawm cov hlab ntsha lymphatic thiab cov qog ntshav lymph. Cov duab no pab cov kws kho mob soj ntsuam seb lub cev lymphatic ua haujlwm zoo li cas thiab txheeb xyuas cov teeb meem tsis zoo. Qee zaum, cov txheej txheem fluoroscintigraphy kuj siv ua ke nrog CT lossis MRI scans kom muab cov duab ntxaws ntxiv.

Cov Cheebtsam Tseem Ceeb ntawm Lymphoscintigraphy:

• Kev txhaj tshuaj ntawm Radiotracer: Cov tshuaj radiotracer raug txhaj rau hauv daim tawv nqaij lossis cov nqaij mos subcutaneous ze ntawm cov qog lymphatic lossis thaj chaw lymphatic uas muaj kev txhawj xeeb.
• Gamma lub koob yees duab thaij duab: Lub koob yees duab gamma ntes tau cov hluav taws xob uas lub radiotracer tso tawm thaum nws txav mus los ntawm lub cev lymphatic, tsim cov duab dynamic.
• Duab tsom xam: Tus kws kho mob xoo hluav taws xob yuav tshuaj xyuas cov duab kom paub seb cov ntshav ntws thiab kev ua haujlwm ntawm lub cev lymphatic zoo li cas, txheeb xyuas cov kev thaiv, lossis nrhiav pom cov cim qhia tias muaj mob qog noj ntshav.

Vim li cas Lymphoscintigraphy thiaj ua tiav?

Kev siv Lymphoscintigraphy los kuaj mob, soj ntsuam, thiab saib xyuas ntau yam mob uas cuam tshuam rau lub cev lymphatic. Nov yog qee qhov laj thawj tseem ceeb uas ua rau kev kuaj mob no:

• Kev Soj Ntsuam Lymphedema: Feem ntau siv Lymphoscintigraphy los ntsuam xyuas lymphedema, ib qho mob uas cov kua lymph sib sau ua ke thiab ua rau o ntawm cov ceg lossis lwm qhov ntawm lub cev. Los ntawm kev pom cov dej ntws ntawm cov kua lymph, lymphoscintigraphy tuaj yeem pab txheeb xyuas seb qhov o yog los ntawm kev thaiv lossis tsis txaus ntws hauv lub cev lymphatic.
• Kev Soj Ntsuam Cov Lymphatic Blockages: Kev siv tshuab Lymphoscintigraphy pab nrhiav pom qhov twg muaj kev thaiv lossis kev thaiv hauv cov hlab ntsha lymphatic. Cov kev thaiv no tuaj yeem tshwm sim vim ntau yam, xws li kev phais, kev kho mob hluav taws xob, kev raug mob, lossis kev kis kab mob. Cov txheej txheem no tuaj yeem qhia qhov twg qhov kev thaiv nyob thiab qhov dav ntawm qhov kev thaiv.
• Cancer Diagnosis thiab Staging: Hauv kev kho mob qog nqaij hlav, kev siv lymphoscintigraphy los ntsuas seb mob qog nqaij hlav puas tau kis mus rau cov qog ntshav (ib qho txheej txheem hu ua metastasis). Piv txwv li, nws feem ntau siv rau hauv kev txiav txim siab ntawm mob qog nqaij hlav mis los txiav txim siab seb mob qog nqaij hlav puas tau kis mus rau cov qog ntshav axillary. Kev ntes cov qog ntshav uas koom nrog yog qhov tseem ceeb rau kev npaj kho mob thiab kev ntsuas qhov kev kwv yees.
• Kev Txheeb Xyuas Cov Lymphatic Malformations: Kev siv Lymphoscintigraphy los txheeb xyuas cov teeb meem lymphatic malformations uas muaj txij thaum yug los, uas yog kev loj hlob tsis zoo lossis teeb meem kev loj hlob hauv cov hlab ntsha lymphatic uas tuaj yeem ua rau o lossis teeb meem lymphatic drainage. Cov teeb meem no tuaj yeem tshwm sim txhua qhov chaw hauv lub cev thiab tej zaum yuav xav tau kev phais.
• Kev Soj Ntsuam Kab Mob: Kev kuaj mob Lymphoscintigraphy tuaj yeem pab txheeb xyuas kev kis kab mob hauv lub cev lymphatic, tshwj xeeb tshaj yog thaum tus kab mob nyob hauv cov qog ntshav. Nws muaj txiaj ntsig zoo rau kev soj ntsuam cov mob xws li lymphadenitis (mob ntawm cov qog ntshav) lossis mob ntsws.
• Qhia Kev Txiav Txim Rau Kev Kho Mob: Muaj tej lub sij hawm, kev siv lymphoscintigraphy los pab txiav txim siab phais mob, tshwj xeeb tshaj yog thaum phais mob qog noj ntshav. Nws pab txheeb xyuas lub qog ntshav hauv lub cev (lub qog ntshav thawj zaug uas cov qog ntshav yuav kis mus rau). Los ntawm kev txheeb xyuas lub qog ntshav hauv lub cev, cov kws phais tuaj yeem tshem nws tawm los soj ntsuam seb puas muaj kev kis mob qog noj ntshav thaum tsis tas yuav tshem lwm cov qog ntshav.
