Ukusetshenziswa kwe-barium sulfate njenge-agent ehlukile kwaqala ekuqaleni kwekhulu lama-20, lapho odokotela bethola ukuthi le nto ingathuthukisa ngokuphumelelayo ukuhlukana kwezithombe ze-X-ray, okwenza isakhiwo sangaphakathi somzimba sicace futhi sibonakale. Ngokuhamba kwesikhathi, ukusetshenziswa kwe-barium sulfate kuye kwaduma kancane kancane futhi ingxenye ebalulekile yokuhlolwa kwe-radiology.
Ukuminyana okuphezulu namandla okumunca okuphezulu kwe-barium sulfate kuma-X-ray kuyisisekelo sokusetshenziswa kwayo njenge-agent ehlukile. Lapho ama-X-reyi edlula emzimbeni womuntu, umehluko wokuminyana kwezicubu ezihlukene ungaholela emazingeni ahlukene okumuncwa kwe-X ray, kwakhe izithombe efilimini noma kuma-digital detectors. Ngenxa yobuningi bayo, i-barium sulfate ingakwazi ukumunca ama-X-ray amaningi, okwenza izingxenye zomzimba ezimbozwe noma ezigcwele i-barium sulfate zibonakale zimnyama esithombeni, zinikeze umehluko ongcono futhi zivumele odokotela ukuba babheke isakhiwo sangaphakathi ngokucacile.
Ukusetshenziswa kwe-barium sulfate ekuhlolweni kwamathumbu kubanzi kakhulu. Ekuhlolweni kwamathumbu aphezulu, iziguli zithatha i-oral barium sulfate suspension, egcwalisa umminzo, isisu, ne-duodenum. Nge-X-ray fluoroscopy noma izithombe, odokotela bangakwazi ukubona ukuma, isikhundla, i-peristalsis yomgudu wokugaya ukudla, kanye nokuba khona kwe-stenosis, izilonda, noma izimila. Ekuhlolweni okuphansi kwamathumbu, i-barium sulfate ingafakwa kukholoni nge-enema ukuze ihlole ukwakheka nokusebenza kwekholoni.
I-Barium sulfate nayo inezinhlelo zokusebenza ezibalulekile ekuhlolweni kwe-imaging ye-urological. Ku-intravenous pyelography (IVP), i-barium sulfate ingajovwa egazini ukuze kubhekwe ukwakheka nokusebenza kwezinso, ureters, nesinye. Ngaphezu kwalokho, i-barium sulfate ingasetshenziselwa ukuthwebula isithombe sesinye ukusiza ukuxilonga izifo zesinye njenge-cystitis, amatshe esinyeni, noma izimila esinyeni.
Ngaphezu kokuhlolwa kwe-gastrointestinal kanye nesistimu yomchamo, i-barium sulfate ingase isetshenziselwe ezinye izivivinyo ze-imaging zezokwelapha ezihlukahlukene. Isibonelo, ekuhlolweni kwe-sinus X-ray, i-barium sulfate ingasetshenziswa ukugcwalisa ikhala lekhala ukuze kuthuthukiswe ukubonakala kwayo. Kwezinye izimo, i-barium sulfate ingase isetshenziselwe i-angiography, ikakhulukazi ku-digital subtraction angiography (DSA). I-Barium sulfate inganikeza ukungafani okwanele ukusiza odokotela baqaphele i-vascular stenosis, occlusion, noma okunye okungavamile.
Uma usebenzisa i-barium sulfate ekucabangeni kwezokwelapha, odokotela bazolungisa ukuhlushwa kanye nomthamo we-barium sulfate ngokuvumelana nezidingo ezithile zokuhlolwa. I-Barium sulfate ivame ukuhlinzekwa ngendlela yokumiswa, futhi iziguli zidinga ukuthatha noma i-enema ngokusho kwemiyalelo kadokotela. Ngesikhathi sokusetshenziswa, kufanele kuqashelwe ukuhlanzeka nokuhlakazeka kwe-barium sulfate ukuze kuqinisekiswe ukucaca nokunemba kwezithombe. Ngaphezu kwalokho, iziguli zingase zidinge ukwenza umsebenzi othile wokulungiselela, njengokuzila ukudla noma ukuhlanza amathumbu, ukuze kuqinisekiswe ukuphumelela kokuhlolwa.
I-Barium sulfate ivame ukubhekwa njenge-agent ehlukile ephephile. Ngenxa yokungamuncwa kwayo umzimba womuntu kanye nobuthi obuphansi, i-barium sulfate iphephile ezigulini ezingaphansi kwezimo ezijwayelekile zokusetshenziswa. Kodwa-ke, isibalo esincane seziguli singase sibe nokungezwani komzimba ne-barium sulfate, okubonakaliswa njengezimpawu ezinjengokucanuzela kwenhliziyo, ukuhlanza, nokuqubuka. Ezimweni ezingavamile, ukusetshenziswa kwe-barium sulfate kungase kubangele izinkinga ezinkulu ezifana nokubhobozwa kwamathumbu kanye ne-peritonitis. Ngakho-ke, lapho usebenzisa i-barium sulfate, odokotela bazohlola ngokucophelela isimo sempilo yesiguli futhi baqaphe ngokucophelela ukusabela kwesiguli ngesikhathi sokuhlolwa.
Ukusetshenziswa kwe-barium sulfate emkhakheni we-imaging yezokwelapha kungenye yezinto ezibaluleke kakhulu ezisetshenziswayo. Njenge-ejenti yokuqhathanisa ye-X-ray, i-barium sulfate idlala indima ebalulekile emathunjini, ohlelweni lomchamo, nakwezinye izivivinyo zezokwelapha ezihlukahlukene. Ukuminyana kwayo okuphezulu kanye nezakhiwo ezinhle kakhulu zokumunca i-X-ray kuyenza ibe yinto ebaluleke kakhulu ekucabangeni kwezokwelapha. Ngokuthuthuka okuqhubekayo kobuchwepheshe be-imaging yezokwelapha, ububanzi bokusebenza nokusebenza kwe-barium sulfate nakho kuthuthuka njalo, kuhlinzeka odokotela ngamathuluzi okuxilonga anembe kakhudlwana nasebenza kahle. Esikhathini esizayo, ukusetshenziswa kwe-barium sulfate emkhakheni we-imaging yezokwelapha kuzoqhubeka nokuthuthukisa, okwenza iminikelo emikhulu empilweni yabantu nasembonini yezokwelapha.
