Nws yog dab tsi rau thiab thaum twg tag nrho lub cev scintigraphy tas?

Zoo Siab

• Thaum puv lub cev scintigraphy tas
• PCI tiav li cas
• Saib xyuas ua ntej kev kuaj mob

Tag nrho lub cev scintigraphy lossis tshawb nrhiav lub cev tag nrho (PCI) yog kev kuaj duab uas thov los ntawm koj tus kws kho mob kom kuaj cov qog qhov chaw, mob nqaij hlav, thiab metastasis. Rau qhov no, cov khoom siv hluav taws xob, hu ua radiopharmaceuticals, yog siv, xws li iodine-131, octreotide lossis gallium-67, nyob ntawm lub hom phiaj ntawm scintigraphy, uas tau tswj hwm thiab nqus tau los ntawm cov plab hnyuv siab raum, emitting hluav taws xob uas tau tshawb pom los ntawm cov khoom siv. Paub dab tsi ntawm radioactive iodine yog rau.

Cov duab tau los siv ib qho cuab yeej, uas taug qab tag nrho lub cev, tom qab ib hnub lossis ob ntawm kev coj ntawm lub zog. Yog li, nws muaj peev xwm txheeb xyuas li cas radiopharmaceutical muab faib rau hauv lub cev. Kev kuaj pom tau hais tias nws yog qhov qub thaum cov tshuaj faib tusyees hauv lub cev, thiab yog qhov cim ntawm tus kabmob thaum lub siab ntawm radiopharmaceutical pom rau hauv ib qho chaw lossis ib cheeb tsam ntawm lub cev.

Thaum puv lub cev scintigraphy tas

Tag nrho lub cev scintigraphy tsom mus tshawb xyuas thaj chaw thawj zaug ntawm cov qog, kev hloov kho thiab seb puas muaj metastasis. Lub radiopharmaceutical siv nyob ntawm lub kaw lus twg lossis khoom koj xav ntsuas:

• PCI nrog iodine-131: nws lub hom phiaj tseem ceeb yog lub qog, tshwj xeeb tshaj yog nyob rau cov neeg uas twb tau tshem tawm cov thyroid lawm;
• Gallium-67 PCI: feem ntau yog ua los xyuas cov kev hloov ntawm cov lymphomas, tshawb txog metastasis thiab tshawb xyuas kev kis kab mob;
• PCI nrog octreotide: nws yog ua tiav los soj ntsuam cov qog cov txheej txheem ntawm neuroendocrine keeb kwm, xws li cov thyroid, mob qog nqaij hlav thiab pheochromocytoma. Saib yuav ua li cas paub thiab kho pheochromocytoma.

Tag nrho lub cev scintigraphy yog ua tiav hauv kev qhia kho mob thiab tsis sawv cev rau kev pheej hmoo rau tus neeg mob, vim tias cov tshuaj tua kab mob hauv lub cev yog raug tshem tawm ntawm lub cev.

PCI tiav li cas

Kev tshawb tag nrho lub cev yog ib txwm ua nyob rau hauv plaub kauj ruam:

1. Kev npaj ntawm cov khoom siv hluav taws xob hauv cov tshuaj yuav tsum tau muab;
2. Kev tswj hwm cov koob tshuaj rau tus neeg mob, nrog rau qhov ncauj lossis ncaj qha rau hauv cov hlab ntsha;
3. Txais cov duab, los ntawm kev nyeem tau ua los ntawm cov khoom siv;
4. Duab ua.

Scintigraphy ntawm tag nrho lub cev tsis ib txwm xav kom tus neeg mob yoo mov, tab sis muaj qee qhov kev pom zoo yuav tsum ua raws li cov tshuaj uas yuav tsum tau ua.

Hauv iodine-131, nws pom zoo kom tsis txhob noj zaub mov ntau nyob rau hauv iodine, xws li ntses thiab mis nyuj, ntxiv rau kev ncua qee yam kev siv qee yam tshuaj, xws li tshuaj vitamin thiab thyroid hormones ua ntej ua qhov kev sim. Yog tias tag nrho lub cev scintigraphy tsis tau ua tiav, tab sis tsuas yog cov thyroid scintigraphy, koj yuav tsum tau yoo tsawg kawg 2 teev. Saib yuav ua li cas cov thyroid scintigraphy tau ua tiav thiab cov khoom noj twg muaj iodine ntau uas yuav tsum tau zam rau kev kuaj mob.

Qhov kev kuaj mob yog ua tiav nrog tus neeg mob pw ntawm nws lub plab thiab kav ntev txog 30 txog 40 feeb. Hauv PCI nrog iodine-131 thiab gallium-67, cov duab tau coj 48h tom qab kev saib xyuas ntawm radiopharmaceutical, tab sis yog tias muaj kab mob xav tias tsam, PCI nrog gallium-67 yuav tsum noj ntawm 4 thiab 6h tom qab kev tswj hwm ntawm cov tshuaj yeeb dej caw. Hauv PCI nrog octreotide, cov duab raug coj ob zaug, ib zaug nrog txog 6 teev thiab ib zaug nrog 24 teev kev tswj hwm tshuaj.

Tom qab kuaj xyuas, tus neeg tuaj yeem rov qab mus ua haujlwm li qub thiab yuav tsum tau haus dej kom ntau kom pab tshem tawm cov tshuaj radioactive sai dua.

Saib xyuas ua ntej kev kuaj mob

Ua ntej yuav raug kuaj lub cev tag nrho, nws yog ib qho tseem ceeb uas tus neeg qhia rau tus kws kho mob yog tias lawv muaj kev fab tshuaj dabtsi, yog tias lawv siv cov tshuaj uas muaj Bismuth, xws li Peptulan, piv txwv, uas siv rau mob plab, lossis yog tias koj cev xeeb tub los yog pub niam mis, raws li kev kuaj mob no tsis pom zoo, vim tias nws yuav cuam tshuam rau tus menyuam.

Cov kev mob tshwm sim rau kev tswj hwm ntawm radiopharmaceuticals tsis tshua muaj, tsis yog vim tsawg kawg yog siv ntau heev, tab sis kev fab tshuaj, tawv nqaij ua pob lossis o tuaj yeem tshwm sim hauv thaj chaw uas cov tshuaj tau tswj hwm. Yog li nws yog ib qho tseem ceeb uas kws kho mob paub txog tus neeg mob tus mob.
