Impso ultrasound: popanda kupweteka ndi kuvulazidwa

Kafukufuku wa ultrasound kawirikawiri sichidetsa nkhawa odwala. Ndipotu, njirayi ndi yopanda phokoso, ndiko kuti, khungu limodzi nalo silinayambe kuonongeka. Ena amaopa kutentha kwa dzuwa, koma amatha kufooka - izi sizithunzi , zotsatira zake sizingatheke potsatira njira ya "ultrasound impso." Kuwonetsa chithunzi chomwecho pachiwonekera kwa munthu wopanda maphunziro a zachipatala ndizosatheka, kotero khulupirirani zomwe adokotala akuganiza.

Kodi ndikuwona chiyani pa ultrasound impso? Kawirikawiri, dokotala akhoza kufufuza malo, mawonekedwe ndi kukula kwake kwa impso potsatira njirayi. Mukhozanso kuyesa magazi opatsirana ndi impso, ndikuwonanso momwe zimakhalira m'matumbo.

Transducer yapadera imatumiza mafunde amphamvu afupipafupi kwambiri (ultrasound) kudzera pakhungu kupita ku ziwalo. Mafunde amenewa "amavuta", akuwonetsa kuchokera ku ziwalo zosiyanasiyana za thupi. Transducer imatenga mafundewa ndipo imatumiza uthenga monga mwa chisankho, zomwe adokotala amawona pawindo panthawi ya impso za ultrasound.

Mitundu yambiri yosiyanasiyana imalepheretsa kulowa kwa mafunde akupanga. Mafunde othamanga kwambiri amadutsa mu fupa, ndipo pang'onopang'ono kudutsa m'malo odzazidwa ndi mpweya. Transducer imatulukira momwe msangamsanga mawotchi amabwerera ndipo dokotala akhoza kuona zotsatira zosiyana pawindo.

Musanayambe ndondomekoyi, gelisi imatha kugwiritsidwa ntchito pakhungu kotero kuti kukhudzana ndi transducer kuli kovuta ndipo palibe chopotoka, komanso kuti pakhale khungu lokongola la transducer pa khungu.

Ndiponso, mu njira yapadera ya ultrasound pogwiritsa ntchito Doppler effect, magazi amatha kulingalira. Dokotala adzazindikira ngati pali vuto kapena kutha kwa magazi kumadera ena a impso.

Ultrasound sizowopsya kwa amayi apakati ndi anthu omwe amatsutsa, chifukwa palibe mvula yamagetsi kapena magetsi omwe amagwiritsidwa ntchito.

Kodi chingawononge impso za ultrasound? Matenda a impso osati chabe. Kusokonezeka kwa ureters ndi chikhodzodzo kukuwonekera. Mukhoza kudziwa majekeseni, madzi oundana, abulu, matumbo, kuchepa kwa mazira, ndipo nthawi zina mukhoza kukayikira kuti ali ndi matenda. Ndipo osati impso zokha, komanso ziwalo zozungulira.

Komanso pansi pa mphamvu ya ultrasound ingatengedwe zitsanzo za ziphuphu - biopsy. Mwachitsanzo, izi zimachitika pamene mukufuna kutsegula chida kapena pamene mukufuna kuika chubu. Pambuyo pa opaleshoni yopangira, ultrasound imaperekedwanso kuti iwonetse momwe ziwalo zatsopano za impso zimamvera. Mwachidule, pali zambiri zomwe mungachite kuti muthe.

Chifukwa ndondomekoyi ndi yopanda phindu, palibe ngozi zomwe zimagwiritsidwa ntchito. Koma zingakhale zosagwira ntchito pazochitika zingapo.

• Ndikunenepa kwambiri (kalasi 3-4);
• Ndizogwiritsa ntchito posachedwapa za mankhwala a barium (pamene iwo sanachokepo thupi);
• Ndi mafuta aakulu opangidwa m'matumbo.

Komabe, nthawi zambiri, palibe zopinga zogwiritsira ntchito ultrasound impso. Kukonzekera kawirikawiri kumakhala kophweka, sikufuna kudya kapena kutenga zinthu zapadera. Chokhacho "koma" - ngati dokotala akukonzekera kuyang'ana chikhodzodzo, muyenera kuchiza, ndiko kuti simungathe kupita kuchimbudzi musanayambe ndondomeko, koma muyenera kumwa madzi ambiri.

Ndiponso, anthu odziwa bwino amalimbikitsa kuti musavalole zovala zatsopano, chifukwa gel osagwiritsidwa ntchito nthawi zina amatsukidwa bwino.

Komabe, nthawi zina dokotala amalimbikira kukonzekera, koma kawirikawiri izi zimangokhalapo pamene ultrasound ikuphatikizidwa ndi njira zina.

Monga lamulo, panthawi yomwe wodwalayo akugona m'mimba mwake. Ngati mumagwiritsa ntchito Doppler effect, mudzamva zisonyezero. Ngati dokotalayo akuyang'aniranso chikhodzodzo, mudzafunsidwa kuti mugulitse, ndiyeno, mwina, idzafufuzidwa m'malo opanda kanthu.

Chinthu chokha chosavomerezeka mu njirayi ndifunika kukhala pamalo amodzi. Komabe, njirayi ndi yabwino kwambiri kuposa yambiri, kotero kuti yothetsera ultrasound ya impso, izo sizidzavulaza, koma dokotala angakhoze kudziwa zambiri zokhudza chigawo cha mkodzo ndi impso.
