Uthini umahluko phakathi kweskena sokukhula se-2D, ukuskena iinkcukacha ezigcweleyo ze-2D, kunye ne-2D NGAPHANDLE KWESIQINISEKISO sokuskena iinkcukacha?

(a) Ukukhula kwe-2D (iiveki ezi-4-40)

- ukwazi iskena esisisiseko sokukhula kosana lwakho esiquka ukujonga ukukhula kosana lwakho, indawo ekuyo i-placenta, inqanaba le-amniotic fluid, ubunzima bomntwana, ukubetha kwentliziyo yosana lwakho, umhla oqikelelwayo, indawo elele kuyo usana kunye nesini kwiiveki ezingama-20 ngaphezulu.Nangona kunjalo, le phakheji ayibandakanyi ukujonga i-anomaly yomntwana.

(b) I-2D EPHELELEYO iskena seenkcukacha (20-25veki)

-ukwazi ukuskena okungaqhelekanga komntwana okubandakanya:

* Isiseko sokukhula kwe-2D scan

* ukubala kweminwe neenzwane

* umqolo kwi-sagittal, i-coronal kunye ne-transverse view

* Onke amalungu ethambo afana ne-humerus, i-radius, i-ulna, i-femur, i-tibia, kunye ne-fibula

*amalungu esisu angaphakathi afana nezintso, isisu, amathumbu, isinyi, imiphunga, idiaphragm, ukufakwa kwenkaba, inyongo njalo njalo.

* Ubume bobuchopho obunje ngecerebellum, cisterna magna, nuchal fold, thalamus, choroid plexus.I-ventricle esecaleni, i-cavum septum pellucidum kunye nokunye.

* Ubume bobuso obunje ngee-orbits, ithambo lempumlo, ilensi, impumlo, imilebe, isilevu, iprofayili yokujonga njalo njalo.

* Isakhiwo sentliziyo esifana neentliziyo zegumbi le-4, i-valve, i-LVOT / RVOT, i-3 inqanawa yokujonga, i-aorta arch, i-ductal arch kunye njl.

Ukuchaneka kokuphononongwa kweenkcukacha ezigcweleyo kunokubona malunga ne-80-90% yesifo somzimba somntwana wakho.

(c) 2D INGXENYE yeskeni yeenkcukacha (26-30veki)

- ukwazi ukuskena okungaqhelekanga komntwana kwakhona kodwa oko kunokuba ngamalungu athile okanye ulwakhiwo alunakubonwa okanye lulinganiswe.Oku kungenxa yokuba i-fetus inkulu kwaye ipakisha esibelekweni, kunzima ukubala iminwe, ukwakheka kwengqondo akunakuchaneka kwakhona.Nangona kunjalo, ubume bobuso, ilungu lesisu, isakhiwo sentliziyo, umqolo kunye nethambo lethambo liya kujongwa ukujonga iinkcukacha.Kwangaxeshanye, siya kubandakanya yonke iparameter yokukhula kwe2d.Ukuchaneka kokuskena kweenkcukacha ezingagqibelelanga kunokubona malunga nama-60% okudida komzimba wosana lwakho.
