Echogenic koob nyob rau hauv cov ntaub so ntswg Biopsy thiab kua dej ntws

Xyuas kom tsis txhob muaj qhov raug mob hauv cheeb tsam thiab zam kev raug mob ntawm lub cev

Percutaneous core needle biopsy (CNB / FNA) thiab cyst / abscess aspiration, thoracentesis / paracentesis / pericardiocentesis yog cov txheej txheem tseem ceeb niaj hnub hauv kev cuam tshuam hluav taws xob thiab sonography. Ntawm no, tus nqi ntawm echogenic koob nyob rau hauv kev uaob qho tib si tus qauv notch (Notch) thiab koob tip pom ib txhij. Ordinary Tru-Tau los yog Chibakoobnrog cov npoo du feem ntau "tso tawm" ntawm cov kaum sab xis lossis hauv cov ntaub so ntswg sib sib zog nqus; Cov tswv lag luam kwv yees qhov tob los ntawm qhov chaw anatomical ib leeg, pheej hmoo ua piv txwv sab nraum lub hom phiaj lesion (tshwj xeeb tshaj yog<1 cm nodules or viable rim of necrotic zones) or injuring posterior vessels/bowel loops upon firing.

Biopsy Scenario Cov ntsiab lus:

Echogenic tsis siv neeg / semi- tsis siv neeg biopsy koob (feem ntau 14G-18G) feature micro-etching lossis txheej txheej hauv zos ntawm qhov ze- lub taub hau thiab ib sab ntawm lub qhov rais sab nraud, tso cai rau tus neeg teb xov tooj kom paub meej ntawm qhov screen: ① lub taub tau nkag mus rau qhov sib thooj ntawm qhov txhab; ② lub qhov rais yuav muab tso rau hauv qhov chaw tsis txaus ntseeg thaum tig; ③ tsis muaj lub nkoj loj lossis cov tshuaj ntsiav tam sim ntawd nyob ib sab ntawm lub ntsis ua ntej ua rau. Muaj feem xyuam rau daim siab, raum, thyroid, mis, prostate, thiab cov qog ntshav qog ntshav.

Fine Needle Aspiration (FNA, 20G–25G), vim tsis muaj zog echo los ntawm nyias shafts, yuav tsum muaj siab FNA echogenic koob nrog puv -ntev los yog ntsis-tsuas yog muaj zog polymer microbubble txheej; Qee lub npe muab Sono-Sheath™- lub tes tsho echogenic polymer haum rau cov koob tshuaj biopsy, hloov kho cov khoom muag uas twb muaj lawm.

Cov kua dej (Paracentesis / Thoracentesis / Abscess Drainage):

Nyob rau hauv loj ascites / pleural effusion, cov koob dawb tej zaum yuav pom, tab sis me me encapsulated effusions los yog loculated abscesses xav kom puncture rau hauv nruab nrab ntawm cov kab noj hniav, zam lub ntsws / plab hnyuv loops. Siv rab koob echogenic (feem ntau yog 18G–16G, 7–15 cm), thawj zaug puncture los ntawm cov phab ntsa parietal tau txheeb xyuas- pom lub taub dot pop rau hauv cov kua dej anechoic yog cov pov thawj ncaj qha tshaj plaws ntawm "kev nkag." Tom qab ntawd, ib txoj hlua khi yog muab tso rau ntawm rab koob, ua raws li txoj kev dilation thiab tso catheter.

Percutaneous Nephrostomy (PCNL tract creation):Ntev nyias (15-20 cm) echogenic puncture koob yog thawj zaug nyob rau hauv ultrasound rau hauv lub raum calyx; cov lus qhia ntxiv txhawb nqa pab hauv kev lees paub nkag mus rau hauv kev sau cov kab ke (cov zis rov qab los yog cov lus qhia pom nyob rau hauv lub dilated calyx), txo cov hluav taws xob raug piv rau X-ray-tsuas yog hauv zos.

Cov lus qhia ua haujlwm:

Hauv - dav hlau (longitudinal) taug qab muab qhov zoo tshaj plaws tag nrho -shaft visualization; rau qhov sib sib zog nqus me me siv "pob zeb sojntsuam + koob ntswj txhim kho" txhawm rau txhawm rau lub taub hau ua ntej kev kho kom zoo.

Nco ntsoov me ntsis koob vibration ntawm biopsy firing- khov / duab lub taub hau txoj hauj lwm ua ntej pab ncej-hoc qhov tob correlation ntawm tus qauv.

Nyob rau hauv cov ntaub so ntswg heev attenuating (fatty daim siab, nyob ze calcifications), ua ntej micro-etched + hauv zos coated composite khoom los tiv thaiv attenuation los ntawm npog lub koob duab ntxoov ntxoo.

Nyob rau hauv luv luv, nyob rau hauv biopsy thiab kua, echogenic koob ua ntau tshaj li "qhia lub koob"-lawv cia cov kws kho mob precisely tswjthaum twg thiab qhov twg coj mus kuaj, ntim dab tsi yog ntes, thiab dab tsi yuav tsum zam, cuam tshuam ncaj qha rau kev kuaj mob txaus (Raws Tus Qauv Zoo) thiab qhov teeb meem hnyav (los ntshav / lub cev perforation) tiv thaiv. Lawv yog cov khoom siv tau zoo rau siab -cov kev pabcuam ultrasound zoo.
