He mea koʻikoʻi ke kiʻi radiological e hoʻokō i ka ʻikepili lapaʻau a kākoʻo i nā urologists i ka hoʻokumu ʻana i ka hoʻokele maʻi kūpono. Ma waena o nā ʻano ʻano kiʻi like ʻole, ua manaʻo ʻia ka tomography computed (CT) i kēia manawa ke kumu kuhikuhi no ka loiloi ʻana i nā maʻi urological ma muli o kona ākea ākea, ka manawa scan wikiwiki, a me ka loiloi piha. ʻO ka mea nui, CT urography.
MOOOLELO
I ka wā ma mua, ua hoʻohana mua ʻia ka urography intravenous (IVU), i kapa ʻia ʻo "excretory urography" a / a i ʻole "intravenous pyelography," e loiloi i ka ʻāpana mimi. Hoʻohana ʻia ka ʻenehana i kahi radiograph maʻemaʻe mua a ukali ʻia e ka hoʻokele intravenous o kahi mea hoʻohālikelike wai-soluble (1.5 ml/kg ke kaumaha o ke kino). Ma hope iho, loaʻa kekahi pūʻulu kiʻi i nā manawa kikoʻī. ʻO nā palena nui o kēia ʻenehana he loiloi ʻelua-dimensional a me ka nalo ʻana o ka anatomy pili.
Ma hope o ka hoʻokomo ʻana i ka tomography computed, ua hoʻohana nui ʻia ʻo IVU.
Eia nō naʻe, i ka makahiki 1990 wale nō, me ka hoʻokomo ʻia ʻana o ka ʻenehana helical, ua wikiwiki loa nā manawa scan i hiki ke aʻo ʻia nā wahi nui o ke kino, e like me ka ʻōpū, i kekona. Me ka hiki ʻana mai o ka ʻenehana multi-detector i nā makahiki 2000, ua hoʻonui ʻia ka hoʻonā spatial, e ʻae ana i ka ʻike ʻana o ka urothelium o ka ʻāpana mimi kiʻekiʻe a me ka ʻōpū, a ua hoʻokumu ʻia ʻo CT-Urography (CTU).
I kēia lā, hoʻohana nui ʻia ka CTU i ka loiloi o nā maʻi urological.
Mai nā lā mua o CT, ua ʻike ʻia e hiki ke hoʻokaʻawale i nā mea o nā helu atomika X-ray spectra o nā ʻenehana like ʻole. ʻAʻole hiki i ka makahiki 2006 i hoʻohana maikaʻi ʻia kēia kumumanaʻo i ke aʻo ʻana i ka ʻiʻo o ke kanaka, a laila alakaʻi i ka hoʻokomo ʻana i ka ʻōnaehana ʻelua-energy CT (DECT) mua i ka hana lapaʻau i kēlā me kēia lā. Ua hōʻike koke ʻo DECT i kona kūpono no ka loiloi ʻana i nā kūlana pathological tract urinary, mai ka haki ʻana o nā mea i loko o ka calculi mimi a i ka lawe ʻana o iodine i nā maʻi maʻi urological.
pomaikai
Hoʻokomo pinepine ʻia nā kuʻuna CT kuʻuna i nā kiʻi precontrast a multiphase postcontrast. Hāʻawi nā CT scanner hou i nā pūʻulu data volumetric i hiki ke kūkulu hou ʻia i nā mokulele he nui a me ka mānoanoa ʻāpana ʻokoʻa, pēlā e mālama ai i ka maikaʻi o ke kiʻi. Ke hilinaʻi nei ka CT urography (CTU) i ke kumu polyphasic, e kālele ana i ka māhele "excretion" ma hope o ka kānana ʻana o ka mea hoʻohālikelike i loko o ka ʻōnaehana hōʻiliʻili a me ka ʻōpū, e hana maoli i kahi urogram IV me ka hoʻomaikaʻi maikaʻi ʻana o ka ʻiʻo.
LIMIT
ʻOiai inā ʻo ka tomography computed contrast-enhanced ka maʻamau kuhikuhi no ke kiʻi mua ʻana o ka ʻāpana mimi, pono e hoʻoponopono ʻia nā palena kūlohelohe. ʻO ka ʻike ʻana i ka radiation a me ka nephrotoxicity ʻokoʻa i manaʻo ʻia he mau hemahema nui. He mea koʻikoʻi ka hōʻemi ʻana i ka nui o ka radiation, ʻoi aku ka nui o nā maʻi ʻōpio.
ʻO ka mea mua, pono e noʻonoʻo mau ʻia nā ʻano hana kiʻi ʻē aʻe e like me ultrasound a me MRI. Inā ʻaʻole hiki i kēia mau ʻenehana ke hāʻawi i ka ʻike i noi ʻia, pono e hana ʻia ma ka protocol CT.
Hoʻopaʻa ʻia ka hoʻokolohua CT hoʻohālikelike ʻia i nā maʻi maʻi i ka radiocontrast a me nā mea maʻi me ka hana renal impaired. No ka hōʻemi ʻana i ka nephropathy i hoʻohālikelike ʻia, ʻaʻole pono e hāʻawi ʻia nā mea maʻi me ka glomerular filtration rate (GFR) ma lalo o 30 ml/min me ka nānā ʻole ʻana i nā pōʻino a me nā pōmaikaʻi, a pono e hoʻohana me ka akahele i nā maʻi me kahi GFR ma ka laulā. 30 a 60 ml / min i nā maʻi.
KA HOPE
I ka wā hou o ka lāʻau lapaʻau pololei, ʻo ka hiki ke hoʻokaʻawale i ka ʻikepili quantitative mai nā kiʻi radiological i kēia manawa a me ka wā e hiki mai ana. ʻO kēia kaʻina hana, i kapa ʻia ʻo radiomics, ua hana mua ʻia e Lambin i ka makahiki 2012 a ua hoʻokumu ʻia ma ka manaʻo e loaʻa i nā kiʻi lapaʻau nā hiʻohiʻona quantitative e hōʻike ana i ke kumu o ka pathophysiology o ke kino. Hiki i ka hoʻohana ʻana i kēia mau hoʻāʻo ke hoʻomaikaʻi i ka hoʻoholo ʻana i ka lāʻau lapaʻau a loaʻa i kahi ākea i ka oncology, e ʻae, no ka laʻana, ka loiloi o ka microenvironment cancer a me ka hoʻololi ʻana i nā koho lapaʻau. I nā makahiki i hala iho nei, ua nui nā haʻawina i hana ʻia e pili ana i ka hoʻohana ʻana i kēia ʻano hana, ʻoiai i ka loiloi ʻana i ka carcinoma urothelial, akā ʻo ia ke kuleana o ka noiʻi.

He mea hoʻolako ʻo LnkMed i nā huahana a me nā lawelawe no ka ʻoihana radiology o ka ʻoihana lapaʻau. Hoʻokumu ʻia nā syringes kiʻekiʻe-press contrast medium e kā mākou hui, meCT hoʻokahi injector,CT pālua poʻo injector,mea hoʻokomo MRIaangiography contrast media injector, Ua kūʻaiʻia aku ma kahi o 300 mau'āpana ma ka home a ma waho, a ua lanakila i ka mahalo o nā mea kūʻai. Ma ka manawa like, hāʻawi pū ʻo LnkMed i nā kola kākoʻo a me nā paipu e like me nā mea hoʻohana no kēia mau hōʻailona: Medrad, Guerbet, Nemoto, a me nā mea ʻē aʻe. Ua manaʻoʻiʻo mau ʻo LnkMed ʻo ka maikaʻi ke kumu kumu o ka hoʻomohala ʻana, a ke hana ikaika nei e hoʻolako i nā mea kūʻai aku i nā huahana a me nā lawelawe kiʻekiʻe. Inā ʻoe e ʻimi nei i nā huahana kiʻi lāʻau lapaʻau, e ʻoluʻolu e kūkākūkā a kūkākūkā me mākou.
