Injongo kunye nendlela ye-ultrasound yesisu

Uvavanyo lwe-Ultrasonic kukujonga ukubonakaliswa kwamaza e-ultrasonic ngumzimba womntu, kukukhanyisa umzimba ngamaza abuthathaka e-ultrasonic, i-wave wave ye-tissue ebonakalisiweyo icutshungulwa ngokwegraphic, kwaye umfanekiso ungabonisa ngokungathanga ngqo ubume bomaleko ngamnye wethishu kwindawo ethile. emzimbeni womntu.I-Ultrasonography yesisu ifanelekile ukuxilongwa kweentlungu zesibindi, i-gallbladder, i-bile duct, i-spleen, i-pancreas, izintso, i-adrenal gland, i-bladder, i-prostate kunye namanye amalungu.Indlela yokuhlola i-Ultrasonic ilula, ukuchaneka okuphezulu kokuxilonga, akukho monakalo kwisigulane.I-Ultrasound ibola ngokukhawuleza emoyeni kwaye ayifanelekanga ukuhlolwa kwamalungu angenanto.

Olu vavanyo lunokukhangela ngokukhawuleza ubungakanani kunye neenguqu zemilo yesibindi, i-gallbladder, i-bile duct, i-spleen, i-pancreas, izintso, i-adrenal gland, i-bladder, i-prostate kunye namanye amalungu;Nokuba ikwimeko eqhelekileyo;Ingaba kukho indawo ehlala kwi-viscera;Izibambi-ndawo zikhulu okanye zingamanzi, ezinje ngamaqhuma, ihematoma kunye namathumba, njl. njl., kwaye ukuya kuthi ga kwinqanaba elithile, inokuchonga ukuba ngaba izibambi-ndawo zilungile okanye ziyingozi, nokuba zicinezelwe zizininzi ezibangqongileyo okanye amalungu;Usenako ukuloba umngxuma wesisu, i-pelvic idumbile i-lymph node;Ukucutheka kwe-gallbladder kunokujongwa ukugweba umsebenzi we-gallbladder;Unokugweba ngokuchanekileyo ukuba kukho i-ascites, nokuba i-ascites encinci inokulinganiswa.

1. Lungiselela ukuhlolwa

(1) Ukuhlolwa kwe-ultrasound yesisu, ngakumbi ukuxilongwa kwe-gallbladder kunye ne-pancreas, kufuneka kube kwisisu esingenalutho.Ngokuqhelekileyo kuyafuneka ukuba uyeke ukutya okunamafutha kwiiyure ezingama-24 phambi koviwo, kwaye ube sisisu esingenalutho ubuncinane iiyure ezisi-8 ngosuku loviwo.Ukuba i-barium fluoroscopy yesisu sele yenziwe ngaphambili, uviwo kufuneka luqhutywe emva kweentsuku ezi-3 zokupheliswa kwe-barium.

(2) Kubafazi abakhulelweyo abarhanelwa ngokubeka indawo ephantsi okanye i-placenta previa, uvavanyo lwe-ultrasound kufuneka luzalise ngokuphakathi isinyi.

(3) Ukukhulelwa kwangethuba (ngaphantsi kweenyanga ezi-3), ukuhlolwa kwe-embryo kunye ne-fetus kunye ne-appendages yayo nayo kufuneka igcwalise isinyi.

(4) Qwalasela isinyi, umchamo, amalungu esibeleko, idlala lengqula, njl.njl., efuna ukuzaliswa okuphakathi kwesinyi ukujonga ukuba isinyi asiqhelekanga.Sela amanzi ayi-1000 ~ 1500ml kwiiyure ezimbini phambi kovavanyo, kwaye ungachami de isinyi sigcwale kwaye isinyi siphume.Ukuba i-cholangiography yenziwe ngaphambili, i-ultrasound kufuneka yenziwe emva kweentsuku ezimbini.

2. Khangela iindlela

(1) isikhundla (1) Isikhundla esisezantsi, isifundo siphefumla ngokuzolileyo, izandla kumacala omabini entloko, ukwenzela ukuba isithuba sembambo sinyuke, kulula ukukhangela, sisetyenziselwa isibindi, i-gallbladder, i-pancreas, i-spleen, izintso ezimbini kunye nesisu. imithambo yegazi enkulu ngodonga lwesisu lwendawo esisiseko yoviwo lwe-ultrasound;Kwakhona jonga ukuba kukho i-ascites, ngakumbi inani elincinci le-ascites elihlala lisetyenziswa indawo;(2) icala lasekhohlo, 30 ° ~ 90 ° ukuya ekhohlo kwindawo supine, phakamisa ingalo yakhe yasekunene emqamelweni, lula ukukhangela isibindi, inyongo, izintso ekunene kunye nedlala adrenal ekunene, isakhiwo ucango lwesibindi ezifana portal vein. kunye namasebe ayo, i-extrahepatic bile duct, ukujonga rhoqo kufuna izifundo ezinzulu ngaxeshanye, ukuphefumla kwesisu emva kokuphefumla ukuphefumula ngokuskena;③ Idecubitus yasekunene, 60 ° ukuya 90 ° ukuya ekunene decubitus.Kukulungele ukuxilonga i-spleen, intso yasekhohlo kunye ne-adrenal gland yasekhohlo, indawo ye-caudal ye-pancreas kunye nokuboniswa kwe-spleen kunye ne-kidney arteries kunye ne-veins.(4) isikhundla isiqingatha recumbent, indawo ehleli: uvavanyo izandla emva ebhedini okanye ngabanye ukuxhasa umqolo wabo, ehleli phezu kwebhedi, ukuze udonga lwesisu ukuba zihlale zikhululekile, kwaye emva koko scan, kulula ukuqaphela ukutyeba, ulwelo lwesisu. , isibindi kunye ne-gallbladder isikhundla esiphezulu kunye nesiphezulu sesisu ngenxa yegesi yamathumbu emathunjini ngakumbi, i-pancreas ibonisa ukungacacanga;(5) indawo ethe tye, yindawo ebalulekileyo yokukhangela izintso zamazwe amabini;(6) idolo kunye nesifuba se-decubitus isikhundla, kulula ukujonga i-distal bile duct kunye ne-gallbladder intamo yamatye kunye nentshukumo yamatye e-bladder.

(2) Uvavanyo lwe-ultrasound yesisu kufuneka lucwangciswe, lubanzi kwaye luqhelekileyo, kwaye luqhutywe ngokulandelelana ngokwamanyathelo athile.
