Xa kuziwa ekuxilongeni iingxaki ezinxulumene nommandla wesifuba, iingcali zonyango zihlala zixhomekeke kwiindlela ezimbini zokucinga:isifuba X-reyikunye nesifuba CT.Ezi ndlela zokucinga zidlala indima ebalulekileyo ekuboneni iimeko ezahlukeneyo zokuphefumla kunye nentliziyo.Ngelixa zombini zizixhobo eziyimfuneko, kubalulekile ukuqonda umahluko phakathi kwazo ukuqinisekisa uxilongo oluchanekileyo kunye nonyango olusebenzayo.
X-ray yesifuba,ekwaziwa ngokuba yiradiograph, bubuchule obusetyenziswa ngokuqhelekileyo obuvelisa umfanekiso omileyo wesifuba kusetyenziswa imitha ye-electromagnetic radiation.Kubandakanya ukuveza indawo yesifuba kwisixa esincinci semitha ye-ionizing ukubamba imifanekiso yemiphunga, intliziyo, imithambo yegazi, amathambo kunye nezinye izinto.I-X-ray yesifuba ingabizi kakhulu, ifumaneka ngokulula, kwaye inika umboniso okhawulezayo wengingqi yesifuba.
Ngakolunye uhlangothi, i-CT scan yesifuba, okanye i-computed tomography, isebenzisa indibaniselwano ye-X-ray kunye nobuchwepheshe bekhompyutha ukuvelisa imifanekiso enqamlekileyo yesifuba.Ngokuvelisa imifanekiso eneenkcukacha ezininzi ezivela kwii-angles ezahlukeneyo, i-CT scan ibonelela ngembono enzulu yesifuba, igxininisa nakwizinto ezingaqhelekanga ezincinci.I-CT scans ibaluleke kakhulu ekuxilongeni iimeko ezinzima kunye nokuhlalutya izakhiwo zangaphakathi zesifuba.
Umehluko omnye obalulekileyo phakathi kwe-X-ray yesifuba kunye ne-CT yesifuba kumandla abo okucinga.Nangona zombini iindlela zobugcisa zivumela ukubonwa kwamalungu kunye nezicubu ngaphakathi kwesifuba, i-CT yesifuba inika inqanaba eliphezulu kakhulu leenkcukacha.I-X-reyi yesifuba inika ujongo olubanzi kodwa isenokungabonakali izinto ezingaqhelekanga okanye utshintsho olufihlakeleyo kwizihlunu.Ngokuchasene noko, i-CT yesifuba inokubona kwaye ibonakalise kunye nezona zakhiwo eziyinkimbinkimbi, okwenza kube luncedo ngakumbi ekuchongeni iimeko ezithile.
Ukucaca kunye nokuchaneka kwesifuba se-CT scan kwenza kube sisixhobo esixabisekileyo ekuxilongeni iimeko ezahlukeneyo zokuphefumula kunye nenhliziyo.Inokuchonga umhlaza wemiphunga, i-pulmonary embolism, inyumoniya, kwaye ivavanye ubungakanani bomonakalo wemiphunga obangelwa zizifo ezinjenge-COVID-19.Ukongezelela, i-chest CT scans isoloko isetyenziswa kubantu abaneemeko zentliziyo ezikrokrelekayo, inika imifanekiso eneenkcukacha zentliziyo kunye nemithambo yegazi ejikelezileyo ukubona izinto ezingaqhelekanga, ezifana nesifo se-coronary artery okanye i-aortic aneurysms.
Ngelixa i-chest CT scan inikezela ngezakhono ezikhethekileyo zokucinga, akusoloko kulukhetho lokuqala lomfanekiso.I-X-reyi yesifuba ngokuqhelekileyo yenziwa njengesixhobo sokuqala sokuhlola ngenxa yokufikeleleka kunye nokufikeleleka.Zihlala zisetyenziselwa ukuchonga ukungahambi kakuhle kwesifuba kunye nokukhokela uphando olongezelelweyo loxilongo, olufana ne-CT scans okanye ezinye iindlela zokucinga.
Omnye umehluko obalulekileyo phakathi kwe-X-ray yesifuba kunye ne-CT yesifuba yizinga lokuvezwa kwemitha.I-X-reyi yesifuba eqhelekileyo ibandakanya ukukhanya okuncinci kwemitha, okuyenza ikhuseleke ngokwentelekiso ukuba isetyenziswe rhoqo.Nangona kunjalo, isifuba se-CT scan sibeka isigulana kwidosi ephezulu yemitha ngenxa yemifanekiso emininzi ye-X-reyi ethathwe kuyo yonke inkqubo.Umngcipheko onxulumene nokusasazeka kwemitha kufuneka ulinganiswe ngononophelo ngokuchasene noncedo olunokubakho lwe-CT scan yesifuba, ngakumbi kwizigulana zabantwana okanye abantu abafuna iskeni ezininzi.
isifuba X-reyikunye nesifuba se-CT scans zizixhobo ezibalulekileyo zokuxilonga ezisetyenziselwa ukuvavanya izifo zokuphefumula kunye nenhliziyo.Ngelixa i-X-ray yesifuba inikezela ngesiseko esisisiseko sendawo yesifuba, i-CT scan inikezela ngemifanekiso ecacileyo kunye nechanekileyo, eyenza ibe yinto efanelekileyo yokuchonga iimeko ezinzima.Ukhetho phakathi kwezi zibini luxhomekeke kwimeko ethile yeklinikhi, ukufumaneka, kunye nenqanaba leenkcukacha ezifunekayo ukuxilongwa ngokuchanekileyo.
