Vascular distribution On power Doppler ultrasound, kwv yees li 90% ntawm cov qog nqaij hlav ib txwm muaj qhov siab tshaj plaws transverse txoj kab uas hla ntau dua 5 hli yuav qhia tau tias muaj vascularity. Cov nodes li qub thiab reactive feem ntau qhia hilar vascularity, los yog pom meej avascular[47- 50
Puas cov qog ntshav qab zib muaj vascularity?
Lymph nodes tau muab faib ua 3 pawg hauv cov hlab ntsha sab hauv raws li cov vascular configuration hauv LN: normal, nrog radially symmetric branching hilar hlab ntsha; tshem tawm, nrog cov hlab ntsha uas muaj qhov chaw eccentric; thiab avascular, tsis muaj vascularity.
Pob cov qog ntshav qab zib?
Cov kab mob qog nqaij hlav (lossis lymphatic) yog ib feem ntawm koj lub cev tiv thaiv kab mob. Nws muaj xws li ib tug network ntawm lymph hlab ntsha thiab lymph nodes. Lymph hlab ntsha zoo li cov hlab ntsha uas sau thiab nqa ntshav los ntawm lub cev. Tab sis tsis txhob nqa ntshav, cov hlab ntsha no nqa cov kua dej ntshiab hu ua lymph.
Puas cov qog ntshav ib txwm muaj vascularity?
LNs li qub feem ntau qhia hilar predominant ib txwm vascularity Cov kab mob qog noj ntshav feem ntau yog vascularised ntau yam tsis muaj kev hloov pauv ntawm cov qauv hilar loj tshaj plaws. Hauv qhov sib piv metastatic lymph nodes tam sim no peripheral lossis sib xyaw vascularity thiab poob ntawm hilar hom vascularisation[13].
Puas yog qog nqaij hlav qog nqaij hlav vascular?
RESULTS. Malignant cov qog ntshav qog ntshav tau pom tias muaj cov vascularity siab dua (0.169 ± 0.147, P < 0.01). Cov qauv vascular ntawm cov kab mob benign feem ntau yog hom avascular lossis hilar (hauv 83% ntawm cov neeg mob). Cov kab mob phem tau tshwm sim los ntawm cov qauv sib xyaw (47%), pom (20%), lossis hom peripheral (11%).
