He aha ka Doppler Imaging?

ʻO ka Ultrasound Doppler imaging ka hiki ke nānā a ana i ke kahe o ke koko ma nā ʻano aʻa, nā ʻaʻa, a me nā moku. Hōʻike pinepine ʻia e kahi kiʻi neʻe ma ka ʻōnaehana ultrasound, hiki ke ʻike maʻamau i kahi hōʻike Doppler mai ke kahe koko kala i ʻike ʻia ma ke kiʻi ultrasound. Hiki i ka Doppler ke wehewehe i nā kala o ke kiʻi ma muli o ke ana ʻana i ke kahe koko ma kahi kikoʻī i kiʻi ʻia.

He ʻokoʻa ke kiʻi Doppler mai ke kiʻi ultrasound kuʻuna ma ke ʻano kumu hoʻokahi: ʻaʻole ia e kiʻi maoli i kekahi hale. Hāʻawi ka ultrasound kuʻuna i nā kiʻi o nā ʻano like ʻole, nā ʻāpana, a me nā veins e ʻike i ka ulu ʻana, nā haʻihaʻi, nā pilikia hoʻolālā, a me nā kūlana ʻē aʻe he nui. ʻO ka Doppler imaging, ma ka ʻaoʻao ʻē aʻe, hana wale i kahi kiʻi o ke kahe koko.

ʻO ka Ultrasound Doppler imaging kahi hana i ʻike ʻia a mahalo nui ʻia ma muli o kona ʻano non-invasive a me ka radioactive ʻole. ʻAʻole hoʻohana ʻo Doppler i ka radiation a i ʻole nā ​​hiʻohiʻona invasive, akā hana like me nā mea hana kiʻi ultrasound ʻē aʻe; ka hoʻohana ʻana i nā hawewe kani kiʻekiʻe i ʻike ʻia a hoʻololi ʻia i kala, nā kiʻi, a me nā neʻe like ʻole.

Nā lawelawe o Doppler Imaging:

He ʻokoʻa ke kiʻi Doppler mai ke kiʻi ultrasound kuʻuna ma ke ʻano kumu hoʻokahi: ʻaʻole ia e kiʻi maoli i kekahi hale. Hāʻawi ka ultrasound kuʻuna i nā kiʻi o nā ʻano like ʻole, nā ʻāpana, a me nā veins e ʻike i ka ulu ʻana, nā haʻihaʻi, nā pilikia hoʻolālā, a me nā kūlana ʻē aʻe he nui.

Hoʻohana ʻia ka Doppler imaging, ma ka ʻaoʻao ʻē aʻe, e ʻike i ke kahe o ke koko a me nā pōʻino like ʻole e hiki mai ana i loko o nā veins, arteries, a me nā kīʻaha koko. Hoʻohana pinepine ʻia ka Doppler imaging no ka ʻike ʻana i ke koko koko, ʻike i ka hana maikaʻi ʻole o nā kiwi i loko o nā veins, e hoʻoholo inā paʻa ʻia nā aʻa, a i ʻole e ʻike i ka emi ʻana o ke kahe koko ma ke kino. Hiki ke nānā a pale ʻia kēia mau mea hoʻoweliweli a pau i ke olakino a me ke ola me ka Doppler imaging.

Hoʻohana ka poʻe i ke kiʻi Doppler no nā noi like ʻole: No ka laʻana, ʻo Doppler cardiac, nāna e nānā i ke kahe koko i a mai ka puʻuwai, he mea maʻamau a koʻikoʻi loa o ka hoʻokolokolo maʻi puʻuwai.

ʻO nā noi Doppler kaulana ʻē aʻe e pili ana i ka Doppler transcranial (ka nānā ʻana i ke kahe koko ma ka lolo a me ke poʻo), Doppler vascular, a me ka Doppler venous a me arterial.
