Yintoni i-CT scan? Masifunde ngayo ngokulula! (CT Scan)

Xa ugqirha wakho ekuxelela ukuba wenze i-CT scan, ngaba waziva usoyika okanye unomdla? "Yintoni le? Ingaba iza kuba buhlungu? Kutheni le nto isenziwa?" Mhlawumbi unemibuzo emininzi efika engqondweni yakho. Iqhelekile kakhulu. Abantu abaninzi abazi kangako ngale nto. Ke namhlanje, masithethe ngale CT scan ngendlela elula kakhulu onokuyiqonda.

Ngamafutshane, yintoni i-CT scan?

I-CT scan, ukuba ndithetha ngokuchanekileyo, yi-'Computed Tomography' scan. Olu luvavanyo olukhethekileyo lwezonyango olusetyenziselwa ukubona izinto ngaphakathi emizimbeni yethu, njengezitho zomzimba, amathambo, kunye nemithambo yegazi, ngokucacileyo. Usenokuba ukhe weva nge-'X-ray' eqhelekileyo. Le CT scan yindlela yokuthatha imifanekiso yemizimba yethu kusetyenziswa uhlobo olufanayo lwe-'X-ray' ray, kodwa ngendlela ephucukileyo ngakumbi.

Cinga ngesonka. Njengokuba sisika isonka, i-CT scanner ithatha imifanekiso emininzi enqamlezileyo yenxalenye ethile yomzimba wethu. Emva koko, ikhompyutha idibanisa yonke le mifanekiso efana nezilayi ukuze idale umfanekiso ocacileyo we-3D wento engaphakathi emzimbeni wethu. Oku kuvumela ugqirha ukuba abone ukuba yintoni kanye kanye engalunganga emzimbeni wakho.

Unjani umatshini we-CT scan?

Lo ngumatshini odla ngokumila njengedonathi enkulu. Uza kulaliswa etafileni embindini womatshini. Emva koko, njengoko itafile ingena kancinci kumatshini, isixhobo esithi ``X-ray``` esingaphakathi kumatshini sijikeleza umzimba wakho size sithathe imifanekiso. Kuqhelekile ukuva isandi esincinci esithi ``gho...gho...'' ngeli xesha.

Yintoni umahluko phakathi kwe-CT, i-MRI kunye ne-PET scans?

Abantu abaninzi bayabhideka phakathi kwezi ntlobo zintathu zeskeni. Nangona zonke ezintathu ziimvavanyo ezijongeka ngaphakathi emzimbeni, indlela ezisebenza ngayo kunye noko zinokukubona zahlukile. Makhe sijonge le theyibhile ukuze siqonde umahluko ngokucacileyo.

Yenziwa njani i-CT scan? Ithatha ixesha elingakanani?

Kuya kufuneka wenze i-scan esibhedlele okanye kwikliniki ekhethekileyo ye-radiology.

Ugqirha usenokukuxelela ukuba ungatyi okanye ungaseli nto kangangeeyure ezimbalwa ngaphambi kokuba uhlolwe. Kuya kufuneka unxibe ilokhwe ekhethekileyo ebonelelwe sisibhedlele kwaye ususe zonke izinto zentsimbi, ezifana namacici, imigexo, kunye nemisesane.

Ingcali ye-radiology iza kwenza olu vavanyo. Uza kulala ebhedini yesikena uze ukhokelwe kancinci ungene kumatshini. Kubalulekile ukuba uhlale ungashukumi kakhulu ngeli xesha . Ukuba uyashukuma, imifanekiso isenokungacaci. Ngamanye amaxesha uya kucelwa ukuba ubambe umphefumlo wakho okwethutyana.

Yintoni i-CT scan ene-contrast?

Ii-CT scans zinokubona lula izinto eziqinileyo emizimbeni yethu, njengamathambo. Kodwa izicubu ezithambileyo, ezifana nesibindi namathumbu, ngamanye amaxesha azibonakali ngokucacileyo.

Kwezi meko, oogqirha basebenzisa idayi ekhethekileyo ukwenza amalungu okanye imithambo yegazi ibonakale icacile kumfanekiso. Oku kubizwa ngokuba yi-'contrast material'. Xa oku kufakwa emzimbeni, kubonakala kumhlophe kwiskeni, nto leyo eyenza amalungu abonakale kakhulu.

Kukho iindlela ezahlukeneyo zokubonelela ngolu 'mahluko' emzimbeni:

• Inaliti: Ifakwa ngqo emthanjeni. Le ndlela isetyenziselwa ukuhlola izinto ezifana nemithambo yegazi, inkqubo yomchamo, nesibindi.
• Ngomlomo: Ngokuyinika njengolwelo lokusela. Oku kusetyenziswa ukuhlola izinto ezifana nomgudu wokugaya ukutya kunye namathumbu.
• Njenge-enema: Ukuba amathumbu amakhulu ayaskenwa, afakwa emzimbeni nge-anus.

Emva kokuskena, ugqirha uya kukucebisa ukuba usele amanzi amaninzi ukuze uncede i-contrast agent iphume emzimbeni wakho ngokukhawuleza.

Yintoni enokuchongwa yi-CT scan? Ngaba ingachongwa ngumhlaza?

Ewe, i-CT scan inokufumanisa iimeko ezininzi, kuquka nomhlaza. Oogqirha bacebisa olu scan ngezizathu ezahlukeneyo.

• Izinto ezifana nokuqhekeka okuntsonkothileyo kunye neethumba zamathambo.
• Jonga utshintsho kwiimeko ezifana nesifo sentliziyo, isifo semiphunga (i-emphysema), kunye neethumba zesibindi.
• Chonga ukwenzakala kwangaphakathi kunye nokopha kwegazi okwenzeka kwingozi.
• Fumana indawo echanekileyo apho kukho ithumba, ihlwili legazi, usulelo, okanye ulwelo olugqithisileyo emzimbeni.
• Njengesikhokelo sokucwangcisa utyando okanye unyango lwemitha.

Indima ye-CT scans ekufumaneni umhlaza

I-CT scan iluncedo kakhulu ekuxilongeni ezinye iintlobo zomhlaza.

• Ukufumana indawo apho ithumba lomhlaza likhona.
• Ukubonelela ngolwazi lokufumanisa inqanaba lomhlaza.
• Ukukhetha indawo efanelekileyo yokwenza i-biopsy.
• Ukubona ukuba umhlaza ubuyile na emva konyango.
• Ukubona ukuba unyango olunikiweyo luphumelele na.

Umzekelo, ii-CT scans zisebenza kakuhle ekufumaneni umhlaza wemiphunga, izintso, isinyi, i-ovarian kunye nomhlaza wesisu.

Ngaba kukho iingozi kunye nemiphumo emibi?

Njengalo naluphi na uvavanyo lwezonyango, i-CT scan inomngcipheko othile, kodwa iphantsi kakhulu .

• Umngcipheko Wokutsalwa Kwemitha: Ii-CT scans zisebenzisa ii-X-reyi, ezaziwa ngokuba yi-ionizing radiation. Izifundo zibonise ukuba ukuvezwa kule mitha ixesha elide kunokubangela umhlaza. Nangona kunjalo, ngenxa yokuba ubungakanani bemitha ekhutshwa kwi-CT scan buncinci kakhulu, umngcipheko wokuba nomhlaza kwi-scan enye mncinci kakhulu, malunga ne-1 kwi-2,000.Ngokubanzi, iingenelo zokwenziwa iskeni zingaphezulu kakhulu kunengozi yokungabi nayo. Thetha nogqirha wakho ngale nto.

• Abafazi abakhulelweyo nabantwana abancinci: Ukuba ukhulelwe, qiniseka ukuba uxelele ugqirha wakho . Ukuba uskenwa, ingakumbi isisu, unganikwa enye indlela, efana ne-ultrasound scan, engasebenzisi imitha. Ukuba uskenwa kumntwana omncinci, kulungile ukubuza ugqirha okanye ingcali yezobuchwepheshe ukuba inqanaba lemitha yomatshini lilungisiwe ukuze lilungele bona.

• Ii-allergies xa kuthelekiswa nezinye izinto: Abanye abantu banokuba ne-allergy kwi-contrast dye. Uninzi lwexesha, ezi zii-reactions ezincinci, ezifana nokurhawuzelela okanye ukurhawuzelela kolusu. Amaxesha amaninzi, i-reaction enzima enokuba yingozi ebomini inokwenzeka. Ngenxa yesi sizathu, abasebenzi bezonyango baya kukujonga okwethutyana emva kwe-scan. Ukuba une-allergy kumayeza, ukutya kwaselwandle, okanye i-iodine, qiniseka ukuba uxelele ugqirha wakho ngaphambi kwe-scan.
