I-Doppler ultrasound

I-Doppler ultrasonography isebenzisa umphumela we-Doppler ukuhlola ukuthi ingabe izakhiwo (ngokuvamile igazi)[32] ziyasondela noma ziqhelelene ne-probe, kanye nesivinini sayo esihlobene. Ngokubala ukushintshwa kwemvamisa yevolumu yesampula ethile, isibonelo, ukugeleza komthambo wegazi noma ijethi lokugeleza kwegazi phezu kwevalvu yenhliziyo, isivinini salo nendlela eya kuyo kunganqunywa futhi kubonakale ngeso lengqondo. I-Colour Doppler isilinganiso sejubane ngesilinganiso sombala. Izithombe ze-Doppler zombala ngokuvamile zihlanganiswa nezithombe zesikali esimpunga (imodi ye-B) ukuze kuboniswe izithombe ze-duplex ultrasonography.Ukusetshenziswa kuhlanganisa:

• I-Doppler echocardiography, ukusetshenziswa kwe-Doppler ultrasonography ukuhlola inhliziyo. I-echocardiogram, ngaphakathi kwemikhawulo ethile, ingakwazi ukukhiqiza ukuhlola okunembile kwesiqondiso sokugeleza kwegazi kanye nesivinini segazi nezicubu zenhliziyo kunoma iyiphi indawo engaqondakali kusetshenziswa umphumela we-Doppler. Izilinganiso zesivinini zivumela ukuhlolwa kwezindawo zevalvu yenhliziyo nokusebenza, noma yikuphi ukuxhumana okungavamile phakathi kohlangothi lwesobunxele nesokudla lwenhliziyo, noma yikuphi ukuvuza kwegazi ngamavalvu (i-valvular regurgitation), ukubalwa kokuphuma kwenhliziyo nokubalwa kwesilinganiso se-E/A[35 ] (isilinganiso sokungasebenzi kahle kwe-diastolic). I-ultrasound ethuthukisiwe kusetshenziswa imidiya yokuqhathanisa ye-microbubble egcwele igesi ingase isetshenziselwe ukuthuthukisa isivinini noma ezinye izilinganiso zezokwelapha ezihlobene nokugeleza.
• I-Transcranial Doppler (TCD) kanye ne-transcranial color Doppler (TCCD), ezikala isivinini sokugeleza kwegazi emithanjeni yegazi yobuchopho nge-transcranially (nge-cranium). Zisetshenziswa njengokuhlola ukusiza ukuxilonga i-emboli, i-stenosis, i-vasospasm ephuma ukopha kwe-subarachnoid (ukopha kusuka ku-aneurysm ephukile), nezinye izinkinga.
• Iziqapheli ze-Doppler fetus, nakuba ngokuvamile zingezona ubuchwepheshe -graphy kodwa kunalokho ezikhiqiza umsindo, zisebenzisa i-Doppler effect ukuze zithole ukushaya kwenhliziyo yengane ukuze inakekelwe ngaphambi kokubeletha. Lezi zibanjwa ngesandla, futhi amanye amamodeli aphinde abonise izinga lokushaya kwenhliziyo ngamabhithi ngomzuzu (BPM). Ukusetshenziswa kwalesi siqapha kwesinye isikhathi kwaziwa ngokuthi yi-Doppler auscultation. I-Doppler fetus monitor ijwayele ukubizwa ngokuthi i-Doppler noma i-fetus Doppler. Iziqapheli ze-Doppler fetus zinikeza ulwazi mayelana nombungu olufana nalolo olunikezwa i-stethoscope yengane.
