Koj yuav tsum paub txog B-ultrasound thiab MRI!
MRI siv cov hlau nplaum muaj zog los co cov dej hauv lub cev, tom qab ntawd ua kom nws xis nyob, hnov qhov kev vibration hauv, thiab tom qab tsim cov duab, koj tuaj yeem soj ntsuam qhov sib txawv ntawm cov ntaub so ntswg thiab cov kab mob. Yog li ntawd, MRI kuj tau raug tso dag hu ua" co kev ntsuam xyuas".
Qhov xwm txheej ntawm kev thov:
NMR tuaj yeem hlais ntawm txhua lub kaum sab xis ntawm qhov xav tau, thiab tsis muaj hluav taws xob. Lub cev nqaij daim tawv thiab cov kab mob pathological ntawm lub hlwb, txha nraub qaum thiab qaum qaum yog zoo dua li CT;
MRI yog rhiab rau cov ntaub so ntswg ntau dua li CT, tshwj xeeb tshaj yog rau cov nqaij mos xws li pob qij txha, cov leeg, thiab cov hlab ntsha hauv nruab nrab, nrog cov qauv pom tseeb.
MRI muaj qhov tshwj xeeb zoo hauv kev sib koom ua ke ntawm tus txha nraub qaum, pob qij txha, qog nqaij hlav, kab mob sib kis, cov qog nqaij hlav thiab cov hlab ntsha.
tsis xws luag:
Hauv qee qhov, MRI tsis zoo rau CT. Xws li: cov ncauj lus kom ntxaws ntawm lub ntsws, cov qauv pob txha, pob txha, thiab lwm yam, yog li qee zaum tus kws kho mob orthopedic yuav tsum tau kuaj xyuas;
Nws yuav tsum tau muab sau tseg tias cov neeg uas muaj cov khoom hlau hauv lawv lub cev thiab cov neeg uas muaj pacemakers yuav tsum tsis txhob tau txais MRI, thiab lawv yuav tsum qhia lawv cov kws kho mob ua ntej kuaj.
B-ultrasound siv ultrasonic tsis nkag mus rau tib neeg lub cev. Thaum lub suab nthwv dej ntsib tib neeg cov ntaub so ntswg, lawv tsim cov nthwv dej reflected. Cov echoes yog cov duab B-ultrasound. Qhov no zoo li thaum xaiv ib lub txiv tsawb, tapping thiab mloog kom nkag siab qhov xwm txheej sab hauv.
Qhov xwm txheej ntawm kev thov:
B-ultrasound paub txog nws qhov kev siv qis, siab zaus, tsis muaj kev puas tsuaj rau tib neeg lub cev, tsis muaj mob, thiab ntau yam kev qhia. Nws yog qhov tshwj xeeb tshaj yog nyob rau hauv kev tshawb pom ntawm tib neeg cov ntaub so ntswg thiab kev soj ntsuam ntawm hemodynamics ntawm cov hlab plawv, xws li: qhov tob ntawm lub rooj lumps, cov hlab ntsha, puncture qhov chaw, thiab lwm yam.
B-ultrasound yog tsis muaj hluav taws xob thiab tuaj yeem siv rau kev kuaj lub cev ntawm cov poj niam cev xeeb tub. Nws kuj tuaj yeem pom qee qhov teeb meem ntawm pob txha xws li pob txha tawg kom tsis txhob xoo hluav taws xob puas tsuaj.
tsis xws luag:
Lub zog nkag mus ntawm B-ultrasound tsis muaj zog, thiab nws nyuaj rau kev kuaj pom cov kabmob hauv nruab nrog cev, xws li lub ntsws thiab cov hnyuv. Nws tseem yog ib qho nyuaj rau kev tso saib ntawm cov duab ultrasound thaum qhov txhab me me los yog qhov sib txawv ntawm qhov acoustic impedance tsis loj, xws li: qog nqaij hlav ntawm li 1cm Nws tsis yooj yim rau kev kuaj pom thiab muaj qee yam kev txwv.
