Yiziphi Intuthuko Yamuva Ezithombeni Zezokwelapha?
Kusukela ekuqaleni kwawo ngawo-1960 kuya kuma-1980, i-Magnetic Resonance Imaging (MRI), i-computerized tomography (CT) scans, kanye ne-positron emission tomography (PET) scans ziye zathuthuka kakhulu. Lawa mathuluzi okuthwebula izithombe zezokwelapha angangenisi umthelela aqhubeke nokukhula ngokuhlanganiswa kwezithombe...Funda kabanzi -
Kuyini ukushiswa kwemisebe?
Imisebe, ngesimo samagagasi noma izinhlayiya, uhlobo lwamandla oludlula lusuka kwenye indawo luye kwenye. Ukuchayeka emisebeni kuyinto evamile ekuphileni kwethu kwansuku zonke, lapho imithombo efana nelanga, ama-oven e-microwave, kanye nemisakazo yezimoto iphakathi kweyaziwa kakhulu. Ngenkathi iningi lalokhu...Funda kabanzi -
Izinyathelo Zokuqapha Nokubola Okunemisebe
Ukuqina kwe-nucleus kungatholakala ngokukhishwa kwezinhlobo ezahlukene zezinhlayiya noma amagagasi, okuholela ezinhlotsheni ezahlukene zokubola kwemisebe kanye nokukhiqizwa kwemisebe ye-ionizing. Izinhlayiya ze-Alpha, izinhlayiya ze-beta, imisebe ye-gamma, kanye ne-neutron ziphakathi kwezinhlobo ezivame ukubonwa...Funda kabanzi -
Ucwaningo lwe-Radiology Lukhombisa Ukonga Izindleko kanye Nezinzuzo Zokuzinza Kwemvelo ze-MRIs kanye ne-CT Scans
Ukubambisana phakathi kweRoyal Philips kanye neVanderbilt University Medical Center (VUMC) kufakazela ukuthi izinhlelo eziqhubekayo ekunakekelweni kwezempilo zingaba nobungane nemvelo futhi zingabizi kakhulu. Namuhla, la maqembu amabili embule okutholakele kokuqala okuvela emzamweni wawo wokucwaninga ohlangene ohlose ukunciphisa...Funda kabanzi -
Izinsizakalo Zokulungisa Okubikezelayo Zithembele ku-CT, i-MRI, kanye ne-Ultrasound njengezindlela ezihamba phambili.
Ngokusho kombiko we-IMV 2023 Diagnostic Imaging Equipment Service Outlook okhishwe muva nje, isilinganiso esimaphakathi sokubaluleka kokusebenzisa noma ukwandisa izinhlelo zokulungisa ezibikezelayo zesevisi yemishini yokuthwebula izithombe ngo-2023 singu-4.9 kwabangu-7. Ngokuphathelene nosayizi wesibhedlela, izibhedlela ezinemibhede engu-300 kuya ku-399 ziphinde...Funda kabanzi -
Indlela Yokuthuthukisa Ukuphepha Kweziguli Ezithola Izithombe Zezokwelapha Ezivamile
Kuleli sonto, i-IAEA ihlele umhlangano we-inthanethi ukuze kubhekwe inqubekela phambili ekunciphiseni izingozi ezihlobene nemisebe yeziguli ezidinga izithombe zezokwelapha njalo, ngenkathi kuqinisekiswa ukugcinwa kwezinzuzo. Emhlanganweni, ababekhona baxoxe ngamasu okuqinisa iziqondiso zokuvikela iziguli kanye...Funda kabanzi -
Iziqondiso Ezintsha Zamazwe Ngamazwe Zokuqapha Imisebe Yesiguli Ezithombeni Zezokwelapha Ziqokomisa Izinzuzo Zokwenziwa Kwedijithali
I-IAEA inxusa odokotela ukuthi bathuthukise ukuphepha kweziguli ngokushintsha kusuka ezindleleni ezisetshenziswa ngesandla kuya kwezedijithali zokuqapha imisebe e-ionizing ngesikhathi sezinqubo zokuthwebula izithombe, njengoba kuchaziwe encwadini yayo yokuqala ngale ndaba. Umbiko omusha Wokuphepha we-IAEA mayelana Nokuqapha Ukuvezwa Kwemisebe Yesiguli...Funda kabanzi -
Ungabhekana Kanjani Nezingozi Ezingaba Khona Zokusebenzisa Ama-Injector Anengcindezi Ephakeme Kuma-CT Scan?
Isihloko esandulele (esinesihloko esithi “Izingozi Ezingaba Khona Zokusebenzisa Umjovo Onomfutho Ophakeme Ngesikhathi Sokuhlolwa Kwe-CT”) sikhulume ngezingozi ezingaba khona zezinaliti ezinomfutho ophezulu kuma-CT scan. Ngakho-ke ungabhekana kanjani nalezi zingozi? Lesi sihloko sizokuphendula ngamunye ngamunye. Ingozi Engaba Khona 1: Ukungezwani komzimba okuhlukile kwemidiya...Funda kabanzi -
Izingozi Ezingaba Khona Zokusebenzisa Umjovo Onomfutho Ophakeme Ngesikhathi Sokuhlolwa Kwe-CT
Namuhla kuyisifinyezo sezingozi ezingaba khona uma usebenzisa ama-injector anomfutho ophezulu. Kungani ama-CT scan edinga ama-injector anomfutho ophezulu? Ngenxa yesidingo sokuxilongwa noma ukuxilongwa okuhlukile, ukuskena kwe-CT okuthuthukisiwe kuyindlela ebalulekile yokuhlola. Ngokuvuselelwa okuqhubekayo kwemishini ye-CT, ukuskena...Funda kabanzi -
Ingabe i-MRI iyindlela engabizi kakhulu yokuhlola iziguli ze-ED ezinesiyezi?
Ucwaningo olusanda kushicilelwa kuyi-American Journal of Radiology lubonisa ukuthi i-MRI ingaba yindlela yokuthwebula izithombe engabizi kakhulu yokuhlola iziguli ezifika emnyangweni wezimo eziphuthumayo ezinesiyezi, ikakhulukazi uma kucatshangelwa izindleko ezingezansi.
