Radiological imaging yakakosha kuenderana nekiriniki data uye kutsigira urologists mukutanga kwakakodzera kutungamira kwevarwere. Pakati pemhando dzakasiyana dzekufungidzira, computed tomography (CT) parizvino inoonekwa seyerengedzo chiyero chekuongororwa kwezvirwere zveurological nekuda kwekuwanikwa kwayo kwakakura, kukurumidza scan nguva, uye kuongororwa kwakazara. Kunyanya, CT urography.
NHOROONDO
Kare, intravenous urography (IVU), inonziwo "excretory urography" uye / kana "intravenous pyelography," yainyanya kushandiswa kuongorora weti. Iyo nzira inosanganisira yekutanga plain radiograph inoteverwa nejekiseni remutsinga remvura-soluble difference agent (1.5 ml/kg uremu hwemuviri). Mushure meizvozvo, nhevedzano yemifananidzo inowanikwa panguva yakatarwa. Iwo maganhuriro makuru eiyi tekinoroji anosanganisira maviri-dimensional ongororo uye kushayikwa kuongororwa kwepedyo anatomy.
Mushure mekuiswa kwekomputa tomography, IVU yakashandiswa zvakanyanya.
Zvisinei, muma1990 chete, nekutanga kushandiswa kwehelical technology, nguva dzema scan dzakakwidziridzwa zvakanyanya kuitira kuti nzvimbo huru dzemuviri, dzakadai sedumbu, dzigone kuongororwa mumasekonzi. Nekuuya kwekombiyuta yakawanda-detector mumakore ekuma2000, kugadziriswa kwepakati kwakagadziridzwa, zvichibvumira kuzivikanwa kweurothelium yepamusoro-soro uye dundira, uye CT-Urography (CTU) yakasimbiswa.
Nhasi, CTU inoshandiswa zvakanyanya mukuongororwa kwezvirwere zveurological.
Kubva pamazuva ekutanga eCT, zvave zvichizivikanwa kuti X-ray spectra emasimba akasiyana anogona kusiyanisa zvinhu zvenhamba dzeatomu dzakasiyana. Yakanga isati yasvika 2006 iyo nheyo iyi yakashandiswa zvakabudirira pakudzidza kwezvinyama zvevanhu, pakupedzisira zvichiita kuti kuiswa kwekutanga-simba-simba CT (DECT) hurongwa mumakiriniki ezuva nezuva. DECT yakakurumidza kuratidza kukodzera kwayo kuongororwa kweurinary tract pathological conditions, kubva pakuparara kwezvinhu muurinary calculi kusvika pakutorwa kweiodine muurological malignancies.
kubatsirwa
Traditional CT protocols anowanzo sanganisira precontrast uye multiphase postcontrast mifananidzo. Yemazuva ano CT scanners inopa volumetric data seti inogona kuvakwazve mundege dzakawanda uye nekusiyana-siyana chidimbu ukobvu, nekudaro kuchengetedza yakanakisa mhando yemufananidzo. CT urography (CTU) zvakare inotsamira pane iyo polyphasic musimboti, ichitarisa pachikamu che "excretion" mushure mekunge mumiriri wekusiyanisa apinda muhurongwa hwekuunganidza uye dundira, achigadzira iyo IV urogram ine yakavandudzwa zvakanyanya kusiyana kwetishu.
LIMIT
Kunyangwe kana kusiyanisa-enhanced computed tomography iri chiyero chereferensi yekufungidzira kwekutanga kweiyo urinary turakiti, zvimiro zvemukati zvinofanirwa kugadziriswa. Radiation kuratidzwa uye kusiyanisa nephrotoxicity inoonekwa seyakanyanya kukanganisa. Kuderedza radiation dose kwakakosha zvakanyanya, kunyanya kuvarwere vadiki.
Kutanga, dzimwe nzira dzekufungidzira dzakadai se ultrasound uye MRI dzinofanira kufungwa nguva dzose. Kana matekinoroji aya asingakwanise kupa ruzivo rwakakumbirwa, chiito chinofanira kutorwa pane CT protocol.
Kusiyana-kuwedzerwa CT kuongororwa kunopikiswa kune varwere vanorwara neradiocontrast agents uye varwere vane kukanganisa renal basa. Kuti uderedze kusiyana-induced nephropathy, varwere vane glomerular filtration rate (GFR) isingasviki 30 ml/min havafanirwe kupihwa midhiya yekusiyanisa pasina kunyatsoyera njodzi uye mabhenefiti, uye inofanira kushandiswa nekuchenjerera kune varwere vane GFR muhuwandu. 30 kusvika 60 ml / min muvarwere.
FUTURE
Munguva itsva yemishonga chaiyo, kugona kufungidzira dhata kubva kumifananidzo yeradiological idambudziko razvino uye remangwana. Iyi nzira, inozivikanwa seradiomics, yakatanga kugadzirwa naLambin muna 2012 uye inobva pane pfungwa yokuti mifananidzo yekiriniki ine huwandu hwezvinhu zvinogona kuratidza pasi pathophysiology yetishu. Kushandiswa kweaya assays kunogona kuvandudza kuita sarudzo yekurapa uye kuwana nzvimbo kunyanya muoncology, zvichibvumira, semuenzaniso, kuongororwa kwekenza microenvironment uye nekupesvedzera nzira dzekurapa. Mumakore mashoma apfuura, zvidzidzo zvakawanda zvakaitwa pakushandiswa kweiyi nzira, kunyangwe mukuongororwa urothelial carcinoma, asi ichi chinoramba chiri kodzero yekutsvakurudza.

LnkMed mupi wezvigadzirwa uye masevhisi eiyo radiology ndima yeindasitiri yekurapa. Musiyano wepakati high-pressure sirinji akagadzirwa uye anogadzirwa nekambani yedu, kusanganisiraCT jekiseni rimwe chete,CT kaviri musoro jekiseni,MRI jekiseniuyeangiography kusiyanisa media injector, zvakatengeswa kumayuniti angangosvika mazana matatu kumba nekune dzimwe nyika, uye akawana kurumbidzwa kwevatengi. Panguva imwecheteyo, LnkMed inopawo kutsigira tsono uye machubhu senge zvinobatika kune anotevera mabhureki: Medrad, Guerbet, Nemoto, nezvimwewo, pamwe neakanaka kumanikidza majoini, ferromagnetic detectors uye zvimwe zvigadzirwa zvekurapa. LnkMed yagara ichitenda kuti mhando ndiyo musimboti webudiriro, uye yanga ichishanda nesimba kupa vatengi zvigadzirwa zvemhando yepamusoro uye masevhisi. Kana iwe uchitsvaga zvigadzirwa zvekufungidzira zvekurapa, unogamuchirwa kubvunza kana kutaurirana nesu.
