Buza
Ukuhlomisa indawo yakho ngobuchwepheshe obufanele bokuthwebula - i-CT noma i-MRI - kudinga ukuqonda okuncane kokuthi indlela ngayinye ibhekana kanjani nezinselele ezithile zomtholampilo nezokusebenza. Lobu buchwepheshe bubili, nakuba buhambisanayo, bufeza izinjongo ezihlukene zokuxilonga ngokusekelwe ezimisweni zabo zokusebenza eziyinhloko, izinhlelo zokusebenza zomtholampilo ezihlukile, kanye namaphrofayela engozi ayingqayizivele. Uhlaka olulandelayo lokuqhathanisa lunikeza imininingwane engasebenza ukwazisa ukutholwa kobuchwepheshe bakho kanye nokuhlela kwamasu.
I-CT Scan Machines vs. Imishini ye-MRI: Umbuzo Wesimiso Somzimba
Imishini ye-CT scan kanye nemishini ye-MRI isebenza njengezihluthulelo eziyinhloko zomzimba womuntu, kodwa isebenza ngezimiso ezihluke ngokuphelele. Ukuqonda lo mehluko obalulekile kubalulekile ekwaziseni izicelo zabo zomtholampilo ezihlukile. Ithebula lokuqhathanisa elilandelayo lichaza umehluko wabo oyinhloko, likuqondise ekukhetheni okuphelele kwezinselele ezithile zokuxilonga.

Umshini wokuskena we-CT |
Umshini we-MRI |
Ubuchwepheshe Obubalulekile |
Imishayo ye-X-ray + ukwakhiwa kabusha kwekhompyutha |
Amandla kazibuthe + ama-radiofrequency pulses |
Isimiso Esiyisisekelo |
Ikala ukuncishiswa kwama-X-ray njengoba edlula ezicutshini ukuze kukhiqizwe izithombe ze-anatomical ngokusekelwe ekuminyana. |
Ijabulisa ama-nuclei e-hydrogen (ama-proton) emanzini nasemangqamuzaneni amafutha; izithombe zakhiwa kusukela kumasignali akhishwa ngesikhathi sokuphumula kwazo. |
Ukusetshenziswa kwemisebe |
Isebenzisa imisebe ye-ionizing (X-rays). |
Ayikho imisebe ye-ionizing (inqubo engeyona i-ionizing). |
Isikhathi Skena |
Fast (ngokuvamile 5-15 imizuzu isikhathi sokuhlolwa). |
Kancane kancane (imvamisa imizuzu engama-30-60 ukuhlolwa ngakunye, kuye ngephrothokholi). |
Isicelo esinembe: Izindlela zokufanisa nezimo zemitholampilo
Lo mehluko oyisisekelo wezobuchwepheshe uhumushela emandleni omtholampilo ahlukene, okusho ukuthi ukukhetha okuphelele kwezimo ezithile zezokwelapha. Ithebula elilandelayo licacisa lapho indlela ngayinye iba ithuluzi lokuxilonga elikhethwayo.
Isicelo |
Umshini wokuskena we-CT |
Umshini we-MRI |
Ukuphazamiseka Kwemizwa |
I-acute intracranial hemorrhage, ukuphuka kogebhezi, ischemic stroke (isigaba esibuhlungu) |
Izimila zobuchopho, izifo eziqeda amandla (isb., i-multiple sclerosis), ukugxilwa kwasendaweni kwesithuthwane, izifo zomgogodla. |
I-Trauma & Emergency |
Ukuhlolwa okusheshayo kwe-polytrauma, ukopha kwangaphakathi, nokuphuka |
Ayifanele ukuhlukumezeka okukhulu; esetshenziselwa ukuhlolwa kwezicubu ezithambile ngemva kokuzinzisa |
I-Oncology |
Ukutholwa kwesimila kanye nokuma emaphashini, esibindini, ezinso nakwezinye izitho ze-parenchymal |
Izimila zezicubu ezithambile, izimila zobuchopho, kanye nokutholakala kwasendaweni okunembile kwezilonda |
Isistimu ye-Musculoskeletal |
Ukuphuka, ukulimala okuhlangene okuyinkimbinkimbi, i-osteomyelitis |
Izinyembezi ze-Ligament/tendon, ukulimala kwe-meniscal, ukulimala koqwanga, i-edema yomnkantsha |
yenhliziyo Isistimu |
Isifo se-coronary artery (nge-CTA), i-pulmonary embolism, i-aortic aneurysms |
I-Cardiomyopathy, isifo senhliziyo se-valvular, ukungavamile kokuzalwa kwenhliziyo |
Esifuba & Amaphaphu |
I-pulmonary embolism, inyumoniya, umdlavuza wamaphaphu, ukuhlolwa kwamaqhuqhuva wamaphaphu |
Izilonda ze-Medistinal ne-hilar, izimila zezicubu ezithambile zesifuba |
Umgogodla |
Ukuphuka komgogodla, ukungazinzi komgogodla, izilonda zamathambo |
Izimila zomgogodla, i-disc herniation, ukucindezelwa kwezimpande zezinzwa, izimo zokuvuvukala |
I-Abdomen & Pelvis |
Isisu esibuhlungu (i-appendicitis, ukuvinjelwa kwamathumbu), ukuhlukumezeka kwesisu, amatshe ezinso |
Izimila zesibindi, izilonda zama-pancreas, izifo zabesifazane (isibeletho/amaqanda), izifo ze-prostate |
Izinketho Ezinolwazi: Ukukala Izingozi Zemishini Ye-CT Scan vs. Imishini ye-MRI
Ukuqonda lezi zinhlelo zokusebenza ezihlukile ingxenye eyodwa kuphela yemibandela yokukhetha. Ukwenza isinqumo unolwazi futhi kudinga ukuhlolwa ngokucophelela kwezingozi ezingokwemvelo, amaphrofayela okuphepha, nezici eziqondene nesiguli ezihambisana nobuchwepheshe obunye. Isiqhathaniso esilandelayo siveza lezi zinto ezibalulekile zokuhlola okunokulinganisela.
Ukucabangela |
Umshini wokuskena we-CT |
Umshini we-MRI |
Ukuvezwa kwemisebe |
Isebenzisa imisebe ye-ionizing (i-X-ray), ethwala ingozi engase ibe khona yomdlavuza. |
Ayikho imisebe ye-ionizing esetshenzisiwe; ithembele kumagnetic field namaza omsakazo. |
Izimila Zensimbi |
Ngokuvamile kuphephile; izimila eziningi aziphazamisi inqubo. |
Kuvinjelwe izimila eziningi (isb., ama-pacemaker, iziqeshana ze-aneurysm); kungabangela izingozi ezinkulu zokuphepha. |
Ukusabela Okuguquguqukayo Ukuze Uqhathanise |
Ama-agent asekelwe ku-iodine ahlotshaniswa nesigameko esiphezulu sokungezwani komzimba okumaphakathi kuya kokunzima. |
Ama-agent asekelwe ku-Gadolinium anezigameko eziphansi zokusabela, ngokuvamile ezithambile. |
Ukuchayeka Emsindweni |
Inqubo yokuskena ithule kancane. |
Ikhipha umsindo ongqongqozayo noma obhuzayo ngesikhathi sokusebenza; ukuvikelwa kwendlebe kuyadingeka. |
I-Claustrophobia |
Ngokuvamile evulekile futhi ngokushesha, kubekezelelwa kangcono iziguli claustrophobic. |
Umhubhe ovalekile ungabangela i-claustrophobia; imiklamo evulekile ingase ibe inketho. |
Ukukhulelwa |
Akunconywa, ikakhulukazi ku-trimester yokuqala, ngenxa yengozi yemisebe enganeni. |
Kubhekwa njengokuphephile ngemuva kwe-trimester yokuqala lapho isetshenziswa ngaphandle kokuqhathanisa; indlela ekhethwayo yokuxilongwa komama okuphuthumayo. |
Isiphetho
Kafushane, ukukhethwa kwamasu phakathi kwemishini ye-CT scan nemishini ye-MRI kuncike ekuboneni izindima zabo ezihambisanayo ekuxilongweni kwesimanje. Imishini ye-CT scan ihamba phambili ekuhloleni ukuhlukumezeka okusheshayo kanye nokunemba kwe-anatomical, kuyilapho imishini ye-MRI inikeza ukungafani okuphakeme kwezicubu ezithambile kanye nemininingwane yemizwa. Ekugcineni, ukucushwa kwesithombe okuphelele kwesikhungo kuncike ekuvumelaniseni izimiso zomzimba ezihlukile zendlela ngayinye, izinhlelo zokusebenza zomtholampilo, kanye namaphrofayili okuphepha anezinjongo ezithile zokunakekelwa kwesiguli kanye nezidingo zokusebenza.
