Ultrasound ntawm nqaij mos mos nyob rau hauv lub caj dab thiab muaj qaub ncaug

Ultrasonography (US) yog ib txoj kev ntawm kev tshawb nrhiav ntawm ib qho kab mob siv ultrasonic tsis. Nws tau lug kis nyob rau hauv cov tshuaj, vim hais tias ntawm nws cov kev nyab xeeb thiab cov theem siab ntawm informativeness. Rau cov mob ntawm pathological dab tsim nyob rau hauv lub muaj qaub ncaug, raws li zoo raws li nyob rau hauv lub caj dab nqaij mos ultrasound nws yog tej zaum cov feem ntau ntau txoj kev. Nyob rau tib lub sij hawm tswj los qhia ntau cov kab mob nyob rau hauv thaum ntxov ua sawv ntawm lawv txoj kev loj hlob.

Caj dab ultrasound yog muaj nyob rau hauv lub nram qab no:

• xub ntiag ntawm palpable tsim nyob rau hauv lub tsev me nyuam cheeb tsam;
• ntawm lub sijhawm twg los ntawm txoj kev loj hlob ntawm pathologic txheej txheem nyob rau hauv lub carotid cov hlab ntsha, uas feem ntau yog kuaj txog lub hauv paus ntawm tsis ua hauj lwm cov tsos mob ntawm cov ntshav khiav tsis zoo hauv lawv, raws li tau zoo raws li ntxhib suab nrov thaum lub sij hawm auscultation receptacles.

Nws yuav tsum tau muab sau tseg tias nyob rau hauv lub thib ob cov ntaub ntawv ultrasound nqaij mos nyob rau hauv lub caj dab yog ib tug ntxiv txoj kev kuaj mob. Yuav kom meej lub mob nyob rau hauv txhua rooj plaub yuav tsum tau siv doplerografii carotid cov hlab ntsha.

Raws li ib tug tshwm sim ntawm lub ultrasound nyob rau hauv lub caj dab cheeb tsam yuav sufficiently loj nrog yooj yim thiab ib tug high degree ntawm responsiveness kom paub tias ob focal thiab diffuse txhab:

focal:

• ntawm (khoom) tsim (lawv yog cov feem ntau nrhiav tom qab xws li ib tug mob, thaum feem ntau ntawm lawv sawv cev rau ib tug kev hloov adenomatous thyroid, txoj kev pheej hmoo ntawm malignancy uas yog tsis tshua muaj);
• cyst (tseeb hlwv yog tsis tshua muaj, lawv thiaj paub hais tias nyob rau hauv cov kev tshwm sim hais tias lawv muaj ib tug ntshiab, du contour nrog anechogenic kab noj hniav (tshwj tsis yog nyob rau hauv tus neeg mob nyob qhov twg muaj ib tug cyst kab noj hniav hemorrhage));
• paug thiab ntshav (ultrasound feem ntau zoo li echogenic tag nrog fuzzy nkhaus thiab anechogenic kab noj hniav hauv hais tias tsis muaj hemorrhage);
• calcifications (hyperechoic cov lug feem ntau cov yam ntxwv ntawm adenomas thyroid, txawm li cas los, thiab tej zaum yuav qhia ntawm malignancy).

diffuse:

• thyroid o nyob rau hauv loj, thaum tswj ib yam ehostruktury;
• thyroid o nyob rau hauv loj nrog lub ntsiab txhais ehostruktury heterogeneity.

Thawj Embodiment diffuse hloov nyiam cov kab mob xws li goiter, tiav nkauj tiav nraug hyperplasia, hyperthyroidism, post-resection sawv thyroid hyperplasia. Nyob rau hauv lub thib ob rooj plaub no nws yog tau nyaj txoj kev loj hlob ntawm multinodular goiter thiab autoimmune thyroiditis.

Nqa tawm xws li diagnostic cov txheej txheem xws li ultrasound kev soj ntsuam ntawm muaj qaub ncaug, nws yog tiag tiag muaj kuab tsuas yog thaum muaj tsawg kawg yog ib tug ntawm cov nram qab no cov tsos mob:

• o ntawm submandibular thiab parotid qaub ncaug muab ib txhij raising lub cev kub;
• formations nyob rau hauv lub xub ntiag ntawm palpable submandibular, parotid thiab / los yog sublingual cheeb tsam;
• lub xub ntiag ntawm mob, tsis xis nyob thiab / los yog o nyob rau hauv lub submandibular, parotid thiab / los yog sublingual cheeb tsam.

nyob rau hauv lub muaj qaub ncaug ntawm ultrasound nqaij mos qhia cov nram qab no pathological dab:

• hlwv;
• paug;
• benign thiab phem hlav;
• contraction los yog expansion ciav qog;
• sialadenoz;
• sialodenit;
• sialolity.

Ua nyob rau hauv thaum ntxov ua sawv, nqaij mos ultrasound feem ntau ua rau nws ua tau kom paub tias cov kab mob nyob rau hauv nws cov earliest theem ntawm txoj kev loj hlob, thiab ua muaj kuab npaj rau nws kev kho mob, uas ho tsub kom tus neeg mob muaj feem ntawm rov qab.
