ke kiʻi ultrasound a me ke kala Doppler ultrasound imaging?
Ma kahi o 20 mau makahiki i hala, ua loaʻa i kekahi mau paionia i hoʻokumu i nā ʻōnaehana hoʻomaʻamaʻa ultrasound ʻē aʻe, ʻoi aku hoʻi ka poʻe mai ʻAmelika Hui Pū ʻIa, he pūʻulu o nā nīnau hoʻokolokolo ultrasound ʻAmelika ʻAmelika ma o nā ala like ʻole.Ua nīnau ʻia kekahi nīnau pane pōkole: He aha ka ʻokoʻa ma waena o COLORULTRASONOGRAPHYa me COLOR DOPPLER ULTRASONOGRAPHY?
He aha ka ʻokoʻa ma waena o ke kiʻi ultrasound kala a me ke kiʻi ultrasound Doppler kala?
I ka manawa i komo ai ke kiʻi ultrasound Doppler kala i Kina, ua kapa ʻia ʻo ia he "ultrasound kala".Ua hoʻohālikelike mau nā kauka ultrasound kala me ka ultrasound Doppler kala, no laila ʻike ʻo Kina i kēia pilikia no ka manawa mua.Pioloke nā kauka a ʻaʻole maopopo i ke ʻano o ka nīnau.
ʻOiaʻiʻo, he nīnau maʻalahi loa kēia.
ʻO ka ultrasound kala ke hōʻike ʻana i kahi hōʻailona kikoʻī o ka ʻike echo i ka wā o ka hoʻokolokolo ʻana me nā lula hoʻololi kala kūikawā, ʻo ia ke kiʻi ultrasound kala.Hiki i kēia mau ʻike echo kikoʻī ke ʻano echo intensity, Doppler frequency shift, hardness information, microbubble information, etc.
pela.ʻO ke kiʻi kala Doppler kekahi o nā ʻano kiʻi kala he nui.Wehe ʻo ia i ka ʻike Doppler frequency shift mai ka ʻike echo a hōʻike iā ia ma ke ʻano o ke kala kala.
Ma waho aʻe o ke kiʻi Doppler kala a mākou i kamaʻāina ai, e nānā i nā ʻano kiʻi ultrasound kala.
Ua ʻike mākou e hōʻike ana ka ultrasound gray-scale ʻelua-dimensional i ka ikaika o ka hōʻailona echo ma ke ʻano o ka hoʻopili ʻana o ka mālamalama.Inā mākou e kala-kala i kekahi wahi a i ʻole ka ʻōlinolino āpau, e loaʻa iā mākou kahi kiʻi kala kala.
Ma luna: Ua hoʻopili ʻia kahi ʻāpana kikoʻī o ka hōʻailona hina hina i ka poni (pua hāmama), a ʻo ka liona me ka ʻōlinolino like e lilo i poni (hōʻike ʻia e ka pua paʻa).
ʻO ke ʻano kiʻi kiʻi ma luna nei e hoʻopili ai i ka ikaika o ka leo i ka waihoʻoluʻu a i ʻole nā pae waihoʻoluʻu ʻē aʻe i kaulana loa ma Kina no kekahi manawa i nā makahiki 1990.Ua kapa ʻia ʻo "2Dpseudo-colorimaging" i kēlā manawa. ʻOiai he nui nā pepa i paʻi ʻia i kēlā manawa, ʻoiaʻiʻo Ua kaupalena ʻia ka waiwai o ka noi. I kēlā manawa, nui nā halemai i hoʻohana i kēia kiʻi e hala e like me ke kala Doppler imaging e hoʻopiʻi i nā maʻi "nā uku ultrasound kala". He hilahila ʻole.
ʻO ka ʻoiaʻiʻo, ʻo nā hōʻailona kala āpau ma ke kiʻi ultrasound kala he mau kala pseudo, a ua hoʻopaʻa ʻia kēia mau hōʻailona kala a hoʻonohonoho ʻia e mākou.
ʻO ka hapa nui o nā mea hanaultrasonic elastography, ka mea i kaulana loa i kēia manawa, hōʻike pū i ka paʻakikī (a i ʻole elastic modulus) o ka ʻiʻo a i ʻole nā ʻeha i loko o kahi ʻano kala-coded, no laila he ʻano ʻano ultrasound kala.
Ma luna: Hōʻike ka elastography nalu shear i ka modulus elastic o ka lesion i ka helu ʻana i ka unahi kala.
Ke pahū ka liʻiliʻi o nā microbubbles, e hoʻopuka ʻia kahi hopena nonlinear ikaika, ʻaʻole i hoʻopili pinepine ʻia me ka ikaika echo.Kāhea mākou i kēia ʻano o ka unuhi ʻana i ka ʻike pili ʻole no ke kiʻi ʻana i ke kiʻi ʻole pili ʻole.Hoʻohana nui ʻia ke kiʻi hoʻopili ʻole e hōʻike i nā microbubbles liʻiliʻi loa a he mea pono loa ia i ka noiʻi ʻana i ka ultrasound.ʻO ka mea maʻamau, hōʻike ʻia kēia hoʻohui ʻole i kahi ʻano kala-coded, no laila he kiʻi kala.
Ma luna: p-selectin microbubble-target imaging hōʻike koho hoʻonui ʻia o ka paia mua ma hope o ka ischemia, a me ka myocardial contrast-hoʻonui sonographic cardiac short-axis kiʻi ma ka hema mua iho ischemia-reperfusion i nāʻiole.
(A) Hōʻike ka ultrasound i hoʻonui ʻia i ka myocardial contrast-enhanced defect (arrow) i ka wā o ka myocardial ischemia.
(B) Ma hope o 45 mau minuke o ka reperfusion.Hōʻike ka pālākiō kala i ka ikaika o nā kiʻi i hoʻopili ʻole ʻia o nā microbubbles.
ʻO ke kiʻi kiʻi kahe koko ma lalo nei he ʻano kiʻi ultrasound kala
