Fetal kuratidzwa nemwaranzi uye njodzi yegomarara reucheche: ndeipi mukana wenjodzi?

Chidzidzo chitsva chakaburitswa musvondo rino Mushonga wePLoS chine chinangwa chekuongorora mukana wekuti kuratidzwa kwemwana ari mudumbu kucomputed tomography kana radionuclide imaging inoitwa panguva yekuzvitakura kunogona kuwedzera njodzi inotevera yegomarara reucheche. Vatsvakurudzi vakagumisa kuti pasinei nehukuru hukuru hwekudzidza kwavo havana kukwanisa kubvisa mukana wengozi shoma, uye vakakurudzira kuti beta hCG yekuongorora (blood pregnancy test) inofanira kuramba ichiitwa muvakadzi vose vanogona kuva nepamuviri vasati vaita radiodiagnostic huru. kuedza. Saizvozvo, kushandiswa kweapron ye lead inodzivirira nzvimbo yepelvic yevakadzi vane nhumbu inokurudzirwa zvakare. Tsvakurudzo yakaitwa naJoel Ray nevamwe vaaishanda navo kubva kuSt. Michael's Hospital, Toronto, Canada, nevamwe vaaishanda navo.

Vanyori vakashandisa dhatabhesi isingazivikanwe yedunhu rose reOntario, Canada (uko hutano hwepasi rose hunowanikwa kune vese vagari) kubatanidza kuratidzwa kwemwaranzi yaamai kune chirwere chinotevera mumwana. Vachishandisa nzira iyi, vanyori vakakwanisa kutevera 1, 835, 517 amai-mwana vaviri vaviri. Mune dataset yose, 5, 590 vakadzi vakaratidzwa kuongororwa kweradiodiagnostic panguva yekuzvitakura; pakati pevana vakazvarwa nevakadzi vakafumurwa ava, paive nemagomarara mana akatevera evana. Paive nevakadzi 1, 829, 927 muboka risingazivikanwe (vasina kuve neradiodiagnostic imaging panguva yekuzvitakura), uye 2, 539 cancers yakawanikwa pakati pevana vakazvarwa nevakadzi ava. Huwandu hwegomarara rehucheche mumapoka akafumurwa akatarisana neasina kufumurwa anofanana nereshiyo yenjodzi ye0.69. Nekudaro, pakanga pachine kusavimbika kwakanyanya muchidzidzo ichi pamusoro penjodzi yehutsinye zvichitevera kuongororwa kweradiodiagnostic. Vatsvakurudzi vakafungidzira "yakagadziriswa hazard ratio" kuti njodzi iite 0.68, ine miganho yekuvimba pakati pe0.25 ne1.80. Iyi nguva yekuvimba (inomiririra kusava nechokwadi) inoratidza kuti kunyange zvazvo vatsvakurudzi vasina kuwana uchapupu hwakajeka hwekuwedzera kwengozi mushure mekufungidzira, vaisagona kubvisa mukana wekuwedzera kuduku, kusvika ku1.8 nguva iyo pamuviri usina kuvharwa.

Zvichipa mukana uyu vanyori vanokurudzira kuti kuongororwa kweradiodiagnostic kunofanirwa kuitwa panguva yekuzvitakura pasi pekukurumidzira kana mamiriro ekukurumidzira, asi kuti nonradiation-emitting imaging, yakadai seMRI uye ultrasonography, inotanga kufungwa, kana zvakakodzera kliniki. Zvinofanira kusimbiswa kuti chidzidzo ichi chine chekuita nekushandiswa kwemaitiro ekufungidzira senge computed tomography (nemamwe marudzi eiyo radionuclide imaging), anowanzo itwa kuongorora kana kusabvisa mamiriro anowanikwa panguva yekukurumidzira, senge pulmonary embolism kana sitiroko - uye kwete routine ultrasound scans inoitwa panguva yekuzvitakura.

Mumaonero anotevera, Eduardo Franco naGuy-Anne Turgeon vanobva kuMcGill University, Montreal, Canada vanokurudzira kuti mubatanidzwa wepasi rose uumbwe kuyedza kubatanidza ruzivo rwezvekusangana-njodzi kubva mukuferefeta kwese kuripo kuti vajekese nyaya iyi uye. kubatsira vanogadzira mitemo mune ramangwana.
