Isu tese tinoziva kuti kuongororwa kwekurapa kwekufungidzira, kusanganisira X-rays, ultrasound,MRI, mishonga yenyukireya uye X-rays, zvakakosha nzira dzekubatsira dzekuongorora kuongororwa uye dzinoita basa rinokosha pakuziva zvirwere zvisingaperi uye kurwisa kupararira kwezvirwere. Zvechokwadi, zvakafanana zvinoshanda kune vakadzi vane mimba yakasimbiswa kana isina kusimbiswa.Zvisinei, kana idzi nzira dzekufungidzira dzichishandiswa kune vakadzi vane pamuviri kana vanoyamwisa, vanhu vazhinji vachanetseka nezvedambudziko, zvingakanganisa hutano hwe fetus kana mwana here? Kungatungamirira kuzvinetso zvakawanda nokuda kwavakadzi vakadaro vamene here?
Zvinonyatsoenderana nemamiriro ezvinhu. Radiologists nevarapi vehutano vanoziva nezvekurapa kwekufungidzira uye njodzi yekufumurwa nemwaranzi yevakadzi vane pamuviri uye fetus. Somuenzaniso, X-ray yepachipfuva inofumura mwana asati aberekwa kumwaranzi yakapararira, nepo X-ray yepadumbu inoisa mukadzi ane pamuviri pamwaranzi yokutanga. Nepo kuratidzwa kwemwaranzi kubva kune idzi nzira dzekurapa kungave kudiki, kuramba uchiratidzira kunogona kuve nemhedzisiro inokuvadza kuna amai uye fetus. Iyo yakanyanya radiation dose vakadzi vane nhumbu vanogona kuoneswa i100msV.
Asi zvakare, iyi mifananidzo yezvokurapa inogona kubatsira kuvakadzi vane pamuviri, kubatsira vanachiremba kuti vape kuongororwa kwakarurama uye kupa mishonga yakakodzera. Mushure mezvose, zvakakosha kune hutano hwevakadzi vane pamuviri nevana vavo vasati vaberekwa.
Ndedzipi njodzi uye matanho ekuchengetedza emhando dzakasiyana dzemifananidzo yekurapa?Ngationgororei izvozvo.
Zviyero
1.CT
CT inosanganisira kushandiswa kweiyo ionizing radiation uye inoita basa rakakosha pakubata pamuviri, nekushandiswa kweCT scans kunowedzera ne25% kubva muna 2010 kusvika 2020, zvichienderana nehuwandu hune chiremera. Nemhaka yokuti CT inosanganiswa nepamusoro pe fetal radiation exposure, zvakakosha kufunga dzimwe sarudzo paunenge uchifunga kushandiswa kweCT muvarwere vane pamuviri. Lead shielding ichenjedzo inodiwa kuti uderedze njodzi yeCT radiation.
Ndedzipi dzakanakisa dzimwe nzira dzeCT?
MRI inofungidzirwa kuti ndiyo nzira yakanakisisa kune CT. Hapana humbowo hunoratidza kuti mwaranzi yemwaranzi iri pasi pe100 mGy panguva yekuzvitakura inobatanidzwa nekuwedzera kwezviitiko zvekuzvarwa malformations, kuzvara mwana akafa, kupfupfudzika, kukura, kana kuremara kwepfungwa.
2.MRI
Kuenzaniswa neCT, mukana mukuru weMRIndeyekuti inogona kuongorora zvakadzika uye zvinyoro zvinyoro mumuviri pasina kushandisa ionizing radiation, saka hapana chekudzivirira kana kupokana kune vane nhumbu.
Pose apo maitiro maviri ekufungidzira aripo, MRI inofanira kufungwa uye inosarudzwa nekuda kwehuwandu hwayo husingaonekwi. Kunyangwe zvimwe zvidzidzo zvakaratidza theoretical fetal mhedzisiro kana uchishandisa MRI, senge teratogenicity, kudziya kwetishu, uye kukuvadzwa kweacoustic, hapana humbowo hwekuti MRI inogona kukuvadza mwana. Kuenzaniswa neCT, MRI inogona kunyatsojeka uye zvakakwana mufananidzo wakadzika zvinyoro zvinyoro pasina kushandiswa kwekusiyanisa vamiririri.
Zvisinei, gadolinium-based agents, chimwe chezvinhu zviviri zvakasiyana-siyana zvinoshandiswa muMRI, zvakaratidzwa kuva nengozi kune vakadzi vane pamuviri. Vakadzi vane pamuviri pane dzimwe nguva vanosangana nedambudziko rakakura pakusiyanisa zvinobudisa nhau, zvakadai sokuramba kunonoka kunonoka, kuputika kwe fetal bradycardia, uye kusununguka nguva isati yakwana.
3. Ultrasonography
Ultrasound zvakare inoburitsa pasina ionizing mwaranzi. Pakave pasina mishumo yekiriniki yemhedzisiro yakaipa yemaitiro e ultrasound pavarwere vane nhumbu uye fetus.
Chii chinonzi ultrasound test yevakadzi vane pamuviri? Kutanga, inogona kusimbisa kana mukadzi ane pamuviri ane pamuviri zvechokwadi; Tarisa zera uye kukura kwe "fetus" uye woverenga zuva rakakodzera, uye tarisa kurova kwemoyo we "fetus", toni yetsandanyama, kufamba, uye kukura kwese. Uyezve, ongorora kana amai vane pamuviri pemapatya, vana vatatu kana kuti vanopfuura, tarisa kana chibereko chiri panzvimbo yokutanga-kutanga asati asununguka, uye tarisa kana mazai evha yaamai uye chibereko chaamai zvakanaka.
Mukupedzisa, kana michina ye ultrasound nemidziyo yakarongedzwa nemazvo, maitiro e ultrasound haaise njodzi dzehutano kuvakadzi vane pamuviri uye fetus.
4. Nuclear Radiation
Kufungidzira mushonga weNukireya kunosanganisira jekiseni reradiopharma mumurwere, iyo inoparadzirwa mumuviri wose uye inoburitsa mwaranzi panzvimbo yainotarirwa mumuviri. Vanaamai vakawanda vanonetseka pavanonzwa shoko rokuti nuclear radiation, asi kuratidzwa kwemwaranzi ye<em>fetus nemishonga yenyukireya kunoenderana nezvinhu zvakasiyana-siyana, zvakadai setsvina yaamai, kubatwa kweradiopharmaceuticals, uye kuparadzirwa kwemwana kweradiopharmaceuticals, kuyerwa kwemwaranzi inobudisa mwaranzi, uye rudzi rwemwaranzi. inoburitswa neradioactive tracers, uye haigone kuve yakajairika.
Mhedziso
Muchidimbu, mifananidzo yezvokurapa inopa ruzivo rwakakosha pamusoro pehutano hwehutano. Panguva yekuzvitakura, muviri wemukadzi unogara uchichinja uye unotapukirwa nezvirwere zvakasiyana-siyana uye zvirwere. Kuongororwa nemishonga yakakodzera kuvakadzi vane pamuviri kwakakosha kuhutano hwavo uye hwevacheche vavo vasati vaberekwa. Kuti tiite zvirinani, sarudzo dzine ruzivo, radiologists nedzimwe nyanzvi dzekurapa dzinofanirwa kunyatsonzwisisa mabhenefiti nemhedzisiro yakaipa yemaitiro akasiyana ekufungidzira ekurapa uye kuratidzwa kwemwaranzi pavakadzi vane pamuviri. Pese apo varwere vane pamuviri nevana vavo vanenge vachangobva kubatwa nemwaranzi panguva yekufungidzira kwekurapa, radiologists uye vanachiremba vanofanirwa kupa maitiro akajeka mune yega yega maitiro. Njodzi dzemwana ane chekuita nekufungidzira kwezvekurapa dzinosanganisira kunonoka kukura nekukura kwe "fetus", kupfupfudzika, kusaumbwa zvakanaka, kusashanda zvakanaka kwehuropi, kukura zvisina tsarukano muvana, uye kuvandudzwa kweuropi. Nzira yekurapa yekufungidzira inogona kusakonzera kukuvadza kune varwere vane pamuviri uye fetus. Nekudaro, kuenderera uye kwenguva refu kuratidzwa kwemwaranzi uye kufungidzira kunogona kuve nemhedzisiro inokuvadza kune varwere uye fetus. Nokudaro, kuitira kuti kuderedze njodzi yekufungidzira kwechiremba uye kuve nechokwadi chekuchengetedzwa kwe "fetus" panguva yekuongorora kufungidzira, mapato ose anofanira kunzwisisa chiyero chehutachiona hwehutachiona pamatanho akasiyana epamuviri.
