Imaging ntawm lub paj hlwb

Yuav kom kawm pathology ntawm lub paj hlwb yam khoom uas yog siv computer duab ntawm lub paj hlwb. Qhov no txoj kev yog uas tsis yog-tus, nws combines cov kev siv ntawm computer technology thiab X-rays. Nrog kev pab los ntawm X-ray khoom yog tau ib tug series ntawm tus ntoo khaub lig-nraaj dluab, uas yog ces yog ua los ntawm ib tug computer. Qhov no txoj kev tso cai rau koj mus kawm nyob rau hauv kom meej qhov nta ntawm nqaij mos, cov pob txha tshuaj, cov hlab ntsha. Xoo tomography ntawm lub paj hlwb muab ho xav paub ntxiv tshaj li ib tug pa X-ray.

Qhov zoo ntawm no txoj kev yog:

- Lub versatility thiab clarity. Duab muab ib tug ncauj lus kom ntxaws daim duab ntawm tag nrho cov hom ntawm fabrics.

- Ceev. Rau kev raug mob los yog tus cwj nrag, qhov no txoj kev yuav pab kom sai sai txiav txim hemorrhage thiab lwm yam kev raug mob. Xoo tomography yuav siv sij hawm ib tug ob peb feeb. Rau magnetic resonance imaging yuav yuav tsum tau ib nrab ib teev.

- MRI yog ib qho yooj yim mus use.

- tsis mob thiab tsis yog-tus.

- profitability. Qhov no txoj kev ntawm kev tshawb fawb yog cheaper (thaum piv nrog magnetic resonance imaging).

- Neeg.

- Cov tau muab peb-dimensional dluab.

Lub mechanism ntawm lub

Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm cov imager muaj ib tug zoo sib thooj rau lub mechanism ntawm X-ray tshuab. Lub apparatus muaj ib tug X-ray qhov twg los, uas tawg yog xa mus rau lub taub hau, thiab sensors, uas hloov lub rays nyob rau hauv lub graphic duab. Fabrics nqus tawg nyob ntawm seb nws ceev, ntau dua qhov nws yog, ntau dua qhov lub haum muaj peev xwm. Tej formations tshwm sim sib zog tshaj qhov tsawg tuab formations. Piv txwv li, cov pob txha muaj ib tug sib zog ntxoov ntxoo, teeb meem ntawm lub paj hlwb, on qhov tsis tooj, ib tsos tsaus tsawv.

daim ntawv thov

Xoo tomography ntawm lub paj hlwb los mus txiav txim lub ntau ntawm cov ntshav uas nyob rau hauv cov kab noj hniav ntawm cov pob txha taub hau thiab pob txha qauv. Txoj kev tshawb no ntawm lwm cov lug (yog tias muaj sij hawm txaus) yog nqa tawm los ntawm txoj kev MRI.

Xoo tomography ntawm lub paj hlwb yuav ntes cov nram qab no pathologies:

- lub hlwb puas tsuaj, los ntshav, pob txha taub hau pob txha lov uas tshwm sim nyob rau txawv lub taub hau raug mob ;

- intracranial hemorrhage, uas muaj arisen raws li ib tug tshwm sim ntawm ib tug mob stroke;

- tej yam tshwm sim ntawm ischemic stroke, uas yuav tshwm sim tsis pub dhau ob peb teev tom qab qhov pib ntawm thawj cov tsos mob. Ntau rhiab diagnostic txoj kev yog magnetic resonance imaging;

- lub hlwb rwj (contrast li yog yuav tsum tau);

- hydrocephalus - ib qho kev nce nyob rau hauv lub loj ntawm lub cerebral ventricles ;

- o;

- tsis xws luag thiab txhab ntawm lub pob txha taub hau pob txha.

Xoo tomography ntawm lub paj hlwb yuav siv tau rau:

- kev ntsuam xyuas cov neeg kawm ntawv ntawm nqaij mos thiab pob txha nyob rau hauv cov neeg mob uas muaj ib tug ntau yam ntawm kev raug mob rau lub ntsej muag, uas yuav pab tau pab txhawb qhov kev npaj ntawm reconstruction nyob rau hauv phais xyaum;

- mob ntawm sab nqaij daim tawv pob txha poob plig, uas muaj peev xwm yuav tawg thaum lub hnov muaj nuj nqi;

- txiav txim pathological dab uas cuam tshuam sinuses;

- txoj kev kho npaj nyob rau hauv ntau yam hlwb hlav;

- Koob cov kev taw qhia thaum me ntawm lub paj hlwb cov ntaub so ntswg;

- txoj kev tshawb no ntawm vascular kab mob;

- kua paug.

Duab ntawm lub paj hlwb cov hlab ntsha yuav tsum siv cov zoo nrog. Los ntawm contrasts to taub qhov tshwj xeeb tshuaj uas txhim kho cov duab zoo thiab pab qhia cov lug uas undetected nyob rau hauv cov pa imaging. Feem ntau siv yotalamat meglumine, diatrizoate sodium. Lub sib piv muaj ib tug high ntom rengenologicheskuyu, yog li kev kawm ntawv uas nws accumulates nyob rau hauv cov duab pleev xim rau nyob kaj lug xim.
