Ukuthwebula izithombe ngemisebe kubalulekile ukuze kuhambisane nedatha yezokwelapha futhi kusekelwe odokotela bezifo zomchamo ekusunguleni ukuphathwa okufanele kwesiguli. Phakathi kwezindlela ezahlukene zokuthwebula izithombe, i-computed tomography (CT) okwamanje ibhekwa njengendinganiso yokubhekisela yokuhlola izifo zomchamo ngenxa yokutholakala kwayo kabanzi, isikhathi sokuskena esisheshayo, kanye nokuhlolwa okuphelele. Ikakhulukazi, i-CT urography.
UMLANDO
Esikhathini esidlule, i-intravenous urography (IVU), ebizwa nangokuthi “i-excretory urography” kanye/noma “i-intravenous pyelography,” yayisetshenziswa kakhulu ukuhlola umgudu womchamo. Le ndlela ihilela i-radiograph yokuqala ecacile elandelwa ukujova nge-intravenous kwe-ejenti yokungafani encibilikayo emanzini (isisindo somzimba esingu-1.5 ml/kg). Ngemuva kwalokho, uchungechunge lwezithombe lutholakala ngezikhathi ezithile. Imikhawulo eyinhloko yale ndlela ifaka phakathi ukuhlolwa okunezinhlangothi ezimbili kanye nokuhlolwa okungekho kwe-anatomy eseduze.
Ngemva kokwethulwa kwe-computed tomography, i-IVU isetshenziswe kabanzi.
Kodwa-ke, ngawo-1990 kuphela, ngokwethulwa kobuchwepheshe be-helical, izikhathi zokuskena zasheshiswa kakhulu kangangokuthi izindawo ezinkulu zomzimba, njengesisu, zazingafunda ngemizuzwana. Ngokufika kobuchwepheshe be-multi-detector ngawo-2000, ukulungiswa kwendawo kwathuthukiswa, okuvumela ukuhlonza i-urothelium yendlela ephezulu yomchamo kanye nesinye, kwase kusungulwa i-CT-Urography (CTU).
Namuhla, i-CTU isetshenziswa kabanzi ekuhlolweni kwezifo zomchamo.
Kusukela ezinsukwini zokuqala ze-CT, kwaziwa ukuthi ama-X-ray spectra anamandla ahlukene angahlukanisa izinto zezinombolo zama-athomu ahlukene. Kwaze kwaba ngo-2006 lapho lesi simiso sasetshenziswa ngempumelelo ekufundweni kwezicubu zomuntu, ekugcineni kwaholela ekungenisweni kohlelo lokuqala lwe-CT (DECT) lwamandla amabili emisebenzini yezokwelapha yansuku zonke. I-DECT ibonise ngokushesha ukufaneleka kwayo ekuhlolweni kwezimo ze-pathological zomgudu womchamo, kusukela ekuqhekekeni kwezinto kuma-calculi womchamo kuya ekuthathweni kwe-iodine kuma-malignancies e-urological.
inzuzo
Izinqubo ze-CT zendabuko ngokuvamile zifaka izithombe zangaphambi kokungafani kanye nezithombe eziningi zangemuva kokungafani. Izikena ze-CT zesimanje zinikeza amasethi wedatha e-volumetric angakhiwa kabusha ngezindlela eziningi futhi enobukhulu obuguquguqukayo besilayi, ngaleyo ndlela kugcinwe ikhwalithi yesithombe enhle kakhulu. I-CT urography (CTU) incike futhi esimisweni se-polyphasic, igxile esigabeni "sokukhipha" ngemva kokuba i-contrast agent isihlunge ohlelweni lokuqoqa kanye nesinye, ngokuyisisekelo idala i-IV urogram enokungafani kwezicubu okuthuthukisiwe kakhulu.
UMKHAWULO
Ngisho noma i-computed tomography ethuthukisiwe iyindlela ejwayelekile yokubhekisela ekuthathweni kwezithombe zokuqala zomzila womchamo, imikhawulo ekhona kufanele ixazululwe. Ukuchayeka emisebeni kanye nobuthi be-nephrotoxicity kubhekwa njengezinkinga ezinkulu. Ukunciphisa umthamo wemisebe kubaluleke kakhulu, ikakhulukazi ezigulini ezisencane.
Okokuqala, izindlela zokuthwebula izithombe ezihlukile njenge-ultrasound kanye ne-MRI kumele zicatshangelwe njalo. Uma lobu buchwepheshe bungakwazi ukunikeza ulwazi oluceliwe, kumele kuthathwe isinyathelo ngokwenqubo ye-CT.
Ukuhlolwa kwe-CT okuthuthukisiwe kwe-Contrast akuvunyelwe ezigulini ezine-allergy kuma-radiocontrast agents kanye neziguli ezinomsebenzi wezinso ongasebenzi kahle. Ukuze kuncishiswe i-nephropathy ebangelwa i-contrast, iziguli ezine-glomerular filtration rate (GFR) engaphansi kuka-30 ml/min akufanele zinikezwe i-contrast media ngaphandle kokulinganisa ngokucophelela izingozi nezinzuzo, futhi kufanele zisetshenziswe ngokuqapha ezigulini ezine-GFR ebangeni eliphakathi kuka-30 no-60 ml/min ezigulini.
IKUSASA
Enkathini entsha yezokwelapha ngokunemba, ikhono lokuthola idatha yobuningi evela ezithombeni ze-radiological liyinselele yamanje neyesikhathi esizayo. Le nqubo, eyaziwa ngokuthi i-radiomics, yasungulwa okokuqala nguLambin ngo-2012 futhi isekelwe emcabangweni wokuthi izithombe zezokwelapha ziqukethe izici zobuningi ezingase zibonise i-pathophysiology eyisisekelo yezicubu. Ukusetshenziswa kwalezi zivivinyo kungathuthukisa ukwenziwa kwezinqumo zezokwelapha futhi kuthole isikhala ikakhulukazi ku-oncology, okuvumela, isibonelo, ukuhlolwa kwe-microenvironment yomdlavuza kanye nokuthonya izinketho zokwelapha. Eminyakeni embalwa edlule, kuye kwenziwa izifundo eziningi mayelana nokusetshenziswa kwale ndlela, ngisho nasekuhlolweni kwe-urothelial carcinoma, kodwa lokhu kusalokhu kuyilungelo locwaningo.

I-LnkMed ingumhlinzeki wemikhiqizo nezinsizakalo zensimu ye-radiology embonini yezokwelapha. Amasirinji aphakathi nendawo anomfutho ophezulu athuthukiswe futhi akhiqizwa yinkampani yethu, okuhlanganisaUmjovo owodwa we-CT,Umjovo wekhanda eliphindwe kabili we-CT,Umjovo we-MRIfuthii-angiography contrast media injector, ithengiswe kumayunithi angaba ngu-300 ekhaya nakwamanye amazwe, futhi ithole udumo kumakhasimende. Ngesikhathi esifanayo, i-LnkMed iphinde inikeze izinaliti namapayipi asekelayo njengezinto ezisetshenziswayo zemikhiqizo elandelayo: i-Medrad, i-Guerbet, i-Nemoto, njll., kanye namajoyinti okucindezela amahle, ama-ferromagnetic detectors kanye neminye imikhiqizo yezokwelapha. I-LnkMed ibilokhu ikholelwa ukuthi ikhwalithi iyinsika yentuthuko, futhi ibilokhu isebenza kanzima ukuhlinzeka amakhasimende ngemikhiqizo nezinsizakalo ezisezingeni eliphezulu. Uma ufuna imikhiqizo yezithombe zezokwelapha, wamukelekile ukubonisana noma ukuxoxisana nathi.
