Mtundu wa Doppler VS Power Doppler

 

Kodi Colour Doppler ndi chiyani?

 

Doppler yamtunduwu imasintha mafunde amawu kukhala mitundu yosiyanasiyana kuti iwonetse kuthamanga ndi komwe magazi amayendera munthawi yeniyeni.

Itha kugwiritsidwa ntchito kuyerekeza momwe magazi amayenda kudzera m'mitsempha yanu pomenya mafunde amphamvu kwambiri (ultrasound) kuchoka pama cell ofiira amagazi.Ultrasound yanthawi zonse imagwiritsa ntchito mafunde amawu kuti ipange zithunzi, koma sizikuwonetsa kutuluka kwa magazi.

Kodi Power Doppler ndi chiyani?

Power Doppler imachokera pakuzindikira ma siginecha oyenda pang'onopang'ono, imachotsa chizindikiro chosinthira pafupipafupi, ndipo imagwiritsa ntchito chizindikiro cha matalikidwe opangidwa ndi mphamvu yamwazi ya maselo ofiira amagazi kuwonetsa kugawa kwa mitsempha yaying'ono kwambiri.

Kodi pali kusiyana kotani pakati pa Colour Doppler ndi Power Doppler?

Colour Doppler imasintha kuyeza kwa magazi kukhala mitundu ingapo kuti iwonetse kuthamanga ndi komwe magazi amayendera m'chombo.

Doppler yamagetsi imakhala yovuta kwambiri kuposa mtundu wa Doppler pozindikira kutuluka kwa magazi, ngakhale siyimapereka chidziwitso chokhudza momwe magazi amayendera.

 

Dawei High-mapeto mtundu ultrasonica diagnostic zida,DW-T8, osati kokha ndi Power Doppler Imaging (PDI), koma Directional Power Doppler Imaging (DPDI).
