Transcranial Doppler ultrasound

Transcranial doppler ultrasound (TCD) ndiyeso yoyezetsa matenda. Imayeza magazi kupita mkati ndi mkati mwa ubongo.

TCD imagwiritsa ntchito mafunde akumveka kuti apange zithunzi zamagazi mkati mwaubongo.

Umu ndi momwe mayeso amachitikira:

• Mudzagona chafufumimba patebulo lokhala ndi phukusi mutu wanu ndi khosi pilo. Khosi lanu latambasulidwa pang'ono. Kapena mutha kukhala pampando.
• Katswiriyu amathira gel osakaniza ndi madzi akachisi anu ndi zikope, pansi pa nsagwada, komanso pansi pa khosi lanu. Gel osakaniza amathandizira mafunde amawu kulowa m'matumba anu.
• Wendo, wotchedwa transducer, amasunthidwa mdera lomwe likuyesedwa. Wendoyo amatumiza mafunde akumveka. Mafunde amawu amapita mthupi lanu ndikungodutsamo komwe mukuphunzira (pamenepa, ubongo wanu ndi mitsempha yamagazi).
• Kompyutala imayang'ana momwe mafunde amawu amapangira akabwerera. Zimapanga chithunzi kuchokera pamafunde amawu. Doppler imapanga phokoso "swishing", lomwe ndi phokoso lamagazi anu loyenda m'mitsempha ndi m'mitsempha.
• Mayesowo atha kutenga mphindi 30 mpaka ola limodzi kuti amalize.

Palibe kukonzekera kwapadera komwe kumafunikira poyesaku. Simusowa kuti musinthe chovala chamankhwala.

Kumbukirani kuti:

• Chotsani magalasi asanayesedwe ngati muwavala.
• Khalani otseka pamene gelisi imagwiritsidwa ntchito m'maso mwanu kuti musayipeze m'maso mwanu.

Gel osavutikira amatha kumva kuzizira pakhungu lanu. Mutha kumva kupsinjika pamene transducer imayenda mozungulira mutu ndi khosi. Kupanikizika sikuyenera kupweteka. Muthanso kumva phokoso la "whooshing". Izi si zachilendo.

Kuyesaku kumachitika kuti mupeze zomwe zimakhudza magazi kupita kuubongo:

• Kuchepetsa kapena kutseka kwa mitsempha muubongo
• Sitiroko kapena kuwonongeka kwanthawi yayitali (TIA kapena ministerroke)
• Kukhetsa magazi pakati pa ubongo ndi minofu yomwe imaphimba ubongo (subarachnoid hemorrhage)
• Kulowetsa mtsempha wamagazi muubongo (ubongo aneurysm)
• Sinthani kuthamanga mkati mwa chigaza (kupanikizika kosakanikirana)
• Sickle cell anemia, kuti awone kuwopsa kwa sitiroko

Lipoti labwinobwino limawonetsa kuthamanga kwa magazi kulowa muubongo. Palibe kuchepa kapena kutsekeka m'mitsempha yamagazi yopititsa mkati ndi mkati mwa ubongo.

Zotsatira zosazolowereka zikutanthauza kuti mtsempha wamagazi ukhoza kuchepetsedwa kapena china chake chikusintha magazi m'mitsempha ya ubongo.

Palibe zowopsa pokhala ndi njirayi.

Zolemba za Transcranial Doppler; TCD kujambula zithunzi; TCD; Transcranial Doppler kuphunzira

• Endarterectomy
• Matenda a ubongo
• Kuukira kwakanthawi kwa Ischemic (TIA)
• Matenda a atherosclerosis amkati mwa carotid
