Uma kuziwa ekuxilongeni izinkinga ezihlobene nendawo yesifuba, ochwepheshe bezokwelapha bavame ukuthembela kumasu amabili wokucabanga:isifuba X-raykanye nesifuba CT.Lezi zindlela zokucabanga zidlala indima ebalulekile ekutholeni izimo ezihlukahlukene zokuphefumula nezenhliziyo.Yize zombili zingamathuluzi abalulekile, kubalulekile ukuqonda umehluko phakathi kwazo ukuze uqinisekise ukuxilonga okunembile kanye nokwelashwa okusebenzayo.
I-X-ray yesifuba,eyaziwa nangokuthi i-radiograph, iyindlela evame ukusetshenziswa yokuthwebula ekhiqiza isithombe esimile sesifuba kusetshenziswa imisebe ye-electromagnetic.Kuhilela ukuveza indawo yesifuba enanini elincane lemisebe ye-ionizing ukuze uthwebule izithombe zamaphaphu, inhliziyo, imithambo yegazi, amathambo, nezinye izakhiwo.I-X-ray yesifuba iyabiza, itholakala kalula, futhi inikeza umbono osheshayo wesifunda sesifuba.
Ngakolunye uhlangothi, isifuba se-CT scan, noma i-computed tomography, sisebenzisa inhlanganisela yama-X-ray nobuchwepheshe bekhompyutha ukuze kukhiqizwe izithombe zesifuba ezihlukene.Ngokukhiqiza izithombe ezinemininingwane eminingi ngama-engeli ahlukene, i-CT scan inikeza umbono ojulile wesifuba, ogqamisa ngisho nokungajwayelekile okuncane kakhulu.Ama-CT scan awusizo ikakhulukazi ekuxilongeni izimo eziyinkimbinkimbi nokuhlaziya izakhiwo zangaphakathi zesifuba.
Umehluko owodwa obalulekile phakathi kwe-X-ray yesifuba kanye ne-CT yesifuba kusemandleni abo wokuthwebula izithombe.Nakuba amasu womabili evumela ukubonwa kwezitho nezicubu ngaphakathi kwesifuba, i-CT yesifuba inikeza izinga eliphakeme kakhulu lemininingwane.I-X-ray yesifuba inikeza umbono obanzi kodwa ingase ingavezi izinto ezingavamile noma izinguquko ezicashile ezicutshini.Ngokuphambene, i-CT yesifuba ingakwazi ukubona futhi ibonise ngisho nezakhiwo eziyinkimbinkimbi kakhulu, iyenze ibe usizo kakhulu ekuboneni izimo ezithile.
Ukucaca nokunemba kwe-CT scan yesifuba kuyenza ibe ithuluzi eliyigugu ekuxilongeni izimo ezihlukahlukene zokuphefumula nezenhliziyo.Ingahlonza umdlavuza wamaphaphu, i-pulmonary embolism, inyumoniya, futhi ihlole izinga lomonakalo wamaphaphu obangelwa izifo ezifana ne-COVID-19.Ukwengeza, izikena zesifuba ze-CT zivame ukusetshenziswa kubantu abanezimo zenhliziyo okusoleka, ezinikeza izithombe ezinemininingwane yenhliziyo nemithambo yegazi ezungezile ukuze kutholwe okungavamile, njengesifo se-coronary artery noma i-aortic aneurysms.
Ngenkathi i-CT scan yesifuba inikezela ngamakhono akhethekile wokuthwebula, akuhlali kuwukukhetha kokuqala kwesithombe.I-X-ray yesifuba ngokuvamile yenziwa njengethuluzi lokuhlola lesinyathelo sokuqala ngenxa yokufinyeleleka kwayo nokufinyeleleka kwayo.Zivame ukusetshenziselwa ukukhomba ukungahambi kahle kwesifuba okuvamile futhi ziqondise uphenyo olwengeziwe lokuxilonga, njengama-CT scans noma ezinye izindlela zokucabanga.
Omunye umehluko oyinhloko phakathi kwe-X-ray yesifuba kanye ne-CT yesifuba izinga lokuchayeka emisebeni.I-X-ray yesifuba evamile ihilela ukuchayeka kancane emisebeni, okuyenza iphephe ngokuqhathaniswa ukuze isetshenziswe njengenjwayelo.Nokho, i-CT scan yesifuba iveza isiguli isilinganiso esiphezulu semisebe ngenxa yezithombe eziningi ze-X-ray ezithathwe kuyo yonke inqubo.Ingozi ehambisana nemisebe kufanele ikalwe ngokucophelela ngokumelene nezinzuzo ezingaba khona ze-CT scan yesifuba, ikakhulukazi ezigulini zezingane noma abantu abadinga izikena eziningi.
ama-X-ray esifubenikanye nesifuba se-CT scans angamathuluzi okuxilonga abalulekile asetshenziswa ekuhloleni izifo zokuphefumula nezenhliziyo.Nakuba i-X-ray yesifuba inikeza ukubuka konke okuyisisekelo kwendawo yesifuba, i-CT scan yesifuba inikeza izithombe ezinemininingwane nezinembayo, iyenze ibe ilungele ukuhlonza izimo eziyinkimbinkimbi.Ukukhetha phakathi kwalokhu kokubili kuncike emongweni othile womtholampilo, ukutholakala, kanye nezinga lemininingwane edingekayo ukuze kuxilongwe okunembile.
