Kuongororwa kwemifananidzo yeX-ray kwakakosha kuti kuwedzere ruzivo rwekiriniki uye kutsigira vanachiremba vezvedundira mukuona kuti varwere vanotarisirwa kutarisirwa zvakanaka. Pakati penzira dzakasiyana dzekuongorora, computed tomography (CT) parizvino ndiyo inoonekwa senzira yekuongorora zvirwere zvedundira nekuda kwekuwanikwa kwayo kwakakura, nguva yekuongororwa nekukurumidza, uye kuongororwa kwakazara. Kunyanya, CT urography.
NHOROONDO
Kare, intravenous urography (IVU), iyo inonziwo "excretory urography" uye/kana "intravenous pyelography," ndiyo yainyanya kushandiswa kuongorora nzira yeweti. Nzira iyi inosanganisira kutanga ne x-ray yekutanga ichiteverwa nekubaiwa jekiseni remushonga unonyungudika mumvura (1.5 ml/kg yehuremu hwemuviri). Mushure mezvo, mifananidzo yakawanda inowanikwa panguva yakatarwa. Zvipingamupinyi zvikuru zvenzira iyi zvinosanganisira kuongorora kwemativi maviri uye kusaongororwa kwemaumbirwo ari pedyo.
Mushure mekuiswa kwe computed tomography, IVU yakashandiswa zvakanyanya.
Zvisinei, muma1990 chete, nekuunzwa kwetekinoroji yehelical, nguva dzekuongorora dzakakurumidza zvikuru zvekuti nzvimbo huru dzemuviri, dzakadai sedumbu, dzaigona kudzidzwa mumasekonzi mashoma. Nekuuya kwetekinoroji ye multi-detector muma2000, spatial resolution yakawedzerwa, zvichibvumira kuzivikanwa kwe urothelium yenzira yepamusoro yeweti nedundira, uye CT-Urography (CTU) yakagadzwa.
Nhasi, CTU inoshandiswa zvakanyanya pakuongorora zvirwere zveurological.
Kubva pamazuva ekutanga eCT, zvave zvichizivikanwa kuti X-ray spectra yesimba rakasiyana inogona kusiyanisa zvinhu zvine maatomu akasiyana. Izvi zvakatozoshandiswa zvinobudirira mukudzidza kwenyama yemunhu muna 2006, zvichizoguma zvaita kuti pave nehurongwa hwekutanga hweCT (DECT) hune simba mbiri mukurapa kwezuva nezuva. DECT yakaratidza nekukurumidza kukodzera kwayo kuongororwa kwezvirwere zvemunzira yeweti, kubva pakuputsika kwezvinhu muweti kusvika pakutora iodine muzvirwere zveweti.
rubatsiro
Maitiro ekare eCT anowanzo sanganisira mifananidzo ye precontrast ne multiphase postcontrast. Ma CT scanner emazuva ano anopa data re volumetric rinogona kugadziriswazve muzvikamu zvakasiyana uye nehukobvu hwezvidimbu zvakasiyana, nokudaro richichengetedza mufananidzo wakanaka. CT urography (CTU) inoshandisawo polyphasic principle, ichitarisa pa "excretion" phase mushure mekunge contrast agent yapinda mu collecting system nedundira, zvichigadzira IV urogram ine tissue contrast yakagadziridzwa zvikuru.
MUGANHU
Kunyangwe kana computed tomography ine contrast-enhanced ndiyo nzira yekutanga yekutora mifananidzo yenzira yeweti, zvipingamupinyi zviripo zvinofanira kugadziriswa. Kuonekwa nemwaranzi uye kukuvadza kwemhando ye contrast zvinoonekwa sezvipingamupinyi zvikuru. Kuderedza huwandu hwemwaranzi kwakakosha zvikuru, kunyanya kuvarwere vadiki.
Chekutanga, dzimwe nzira dzekufungidzira dzakadai se ultrasound ne MRI dzinofanira kugara dzichifungwa. Kana matekinoroji aya asingakwanise kupa ruzivo rwakumbirwa, matanho anofanira kutorwa zvichienderana ne CT protocol.
Kuongororwa kweCT kwakavandudzwa hakubvumidzwe kuvarwere vane allergy kune zvinokonzeresa radiocontrast uye varwere vane dambudziko reitsvo. Kuti kuderedze contrast-induced nephropathy, varwere vane glomerular filtration rate (GFR) iri pasi pe30 ml/min havafanirwe kupihwa contrast media vasina kunyatsoongorora njodzi nemabhenefiti, uye inofanira kushandiswa nekungwarira kuvarwere vane GFR iri pakati pe30 kusvika 60 ml/min muvarwere.
RANGWA
Munguva itsva yekurapa kwakanyatsojeka, kugona kuwana data rehuwandu kubva kumifananidzo ye radiology idambudziko riripo uye remangwana. Maitiro aya, anozivikanwa se radiomics, akatanga kugadzirwa naLambin muna 2012 uye akavakirwa papfungwa yekuti mifananidzo yekiriniki ine zvinhu zvehuwandu zvinogona kuratidza pathophysiology iri pasi penyama. Kushandiswa kwekuyedza uku kunogona kuvandudza sarudzo dzekurapa uye kuwana nzvimbo kunyanya mu oncology, zvichibvumira, semuenzaniso, kuongororwa kwenzvimbo yekenza uye kukanganisa sarudzo dzekurapa. Mumakore mashoma apfuura, zvidzidzo zvakawanda zvakaitwa pakushandiswa kwenzira iyi, kunyangwe pakuongorora urothelial carcinoma, asi izvi zvinoramba zviri kodzero yekutsvagisa.
