ʻO ka tomography helu, ʻike nui ʻia ma lalo o ka huaʻōlelo o "scanner", i ʻike ʻia no ka manawa mua ma 1972. Ke hoʻohana nei kēia loiloi radiological i nā kukuna X. lawe ʻia e kahi radiologist, kiʻi ʻia i nā kiʻi kikoʻī i ʻekolu mau ana. Hiki i ka tomography helu ke hoʻopaʻa i nā ʻōnaehana o ka mea maʻi a ʻike i kekahi mau mea kūpono ʻole ma mua o nā hoʻokolohua ʻē aʻe.

ʻO kahi tomography compute (CT) kahi loiloi x-ray. ʻO kēia ʻano hana kiʻi olakino, hana ʻia e kahi radiologist, kāhea ʻia ia he scanner (a i ʻole CT-Scan: i ka ʻōlelo Pelekania, tomography i helu ʻia). Hoʻohui ia i ka hoʻohana o nā kukuna X me kahi ʻōnaehana kamepiula. Loaʻa kēia i nā kiʻi ʻāpana maikaʻi o ke kino. 

Aia i ke apo he Tube x-ray a me kahi o nā mea ʻike:

• ke kaʻapuni nei ke kukuna x-ray a puni ka mea maʻi;
• Hōʻiliʻili nā mea huli X i nā ʻano o nā kaola i hala i ke kino o ka mea maʻi;
• kālailai ʻia e kahi kamepiula, e ʻae kēia ʻike i ka hana ʻana o kahi kiʻi. ʻO ia he algorithm hana hou kiʻi matematika i hiki ai ke kiʻi i ka ʻike o ka meaola.

Hiki ke aʻo pākahi ʻia nā ʻōhua. Pēlā i hiki ai ke kūkulu hou i 2D a i ʻole 3D kiʻi o nā ʻano anatomical. ʻO ka liʻiliʻi o ka ʻike lesion liʻiliʻi, keu hoʻi, hoʻomaikaʻi nui ʻia me ka scanner.

Hoʻohana o kahi mea hoʻohālikelike

I mea e hoʻomaikaʻi ai i ka ʻike ʻana o nā nāʻa, hoʻohana pinepine ʻia kahi huahana hoʻohālikelike iodine. Hōʻike waha ʻia ia, a i ʻole i loko o ke kino. Pono e hoʻopili i ka ʻume i ka mea hoʻomanawanui, ke ʻano hoihoi, ka pōʻaiapili. Pono nā mahele lāʻau injected i ka hana ma muli o ke kaupaona o ka mea maʻi. 

ʻO kēia mea hoʻohālikelike kahi mea e hoʻopili i kekahi mau ʻāpana o ke kino. ʻO ka pahuhopu e hōʻike iā lākou ma nā kiʻi i kiʻi ʻia i ka wā o ka hoʻokolokolo. Hoʻopili ʻia kēia mau iodined media media, kahi laʻana e hoʻolilo i ke kahihi urinary a me nā kīʻaha koko i loko o ke ʻano o kahi mea i kapa ʻia ʻo iomeprol. He mea nui ia e nānā i nā pilikia maʻi ʻaʻa, e ola nei me ka nānā ʻole i ke ala o ka hoʻokele a me ka hopena.

Ma kahi o ʻelima mau miliona scanners i hana ʻia ma Palani i kēlā me kēia makahiki, i nā makahiki i hala iho nei (2015 huahelu), 70 miliona ma ʻAmelika Hui Pū ʻIa. ʻAʻole hōʻike ʻia kēia hōʻoia no nā wahine hāpai.

Pono ke kiʻi olakino no ka hoʻokumu ʻana i kahi kuhi, loiloi i ke koʻikoʻi o kahi pathology, a i ʻole me ka hōʻoia ʻana i ka maikaʻi o kahi lapaʻau. ʻO ka maikaʻi o ka nānā ʻana me ka scanner hāʻawi ia i ka ʻike kikoʻī ma nā wahi i hoʻopaʻa ʻia. Kuhi ʻia ka tomography helu i ka ʻimi ʻana i nā leona i ʻike ʻole ʻia ma ka ultrasound a i ʻole nā ​​kukuna x maʻamau:

• Brain. No ka ʻimi kūpilikiʻi, nā hōʻailona no ka tomography helu i kēia lā e pili nui ana i nā mea maʻi i loaʻa i kahi poʻo poʻo, a i ʻole ia e manaʻo ʻia ai he hemorrhage intracranial. No ka ʻimi ʻana i nā pathologies cerebral non-traumatic, ʻoi aku ka MRI e hoʻokō ʻia (kahi ninaninau e hoʻohana ana i kahi kahua uila a me nā nalu lekiō);

• Kaona. ʻO ka scanner i kēia lā ka hoʻokolohua radiological maikaʻi loa no ka ʻimi ʻana i ka thorax;

• 'Apena. ʻO ka tomography helu kekahi o nā hōʻike x-ray maikaʻi loa no ka mākaʻikaʻi ʻana i ka ʻōpū. Ma kahi kikoʻī, hāʻawi ia i kahi mahalo maikaʻi i nā "intra-ʻōpū o ke kino" āpau;

• Liona iwi. ʻAe ka mea scanner i ka loiloi i nā lehelehe iwi e like me nā haki;

• Nā Pathologies maʻi. ʻO ka tomography compute kahi hōʻike maʻamau e nānā ana i ka embolism pulmonary a i ʻole ka dissection aortic.

Maikaʻi loa ka tomography compute no ka mākaʻikaʻi ʻana i ka ʻōpū a me ka thorax no ka mea hāʻawi ia i nā kiʻi hoʻonā kiʻekiʻe loa. Hoʻonui ʻia nō hoʻi i ka ʻimi ʻana i nā haki, a i ʻole ka puna a i ʻole ke koko i nā aʻa. ʻO ka scan CT, ma ka ʻaoʻao ʻē aʻe, ʻaʻohe mea hoʻohana iki no ke aʻo ʻana i nā mea palupalu, koe wale no ka ʻimi ʻana i ka helu ʻana ma kahi tumo.

• kahe ana ke koko;
• ʻōpū;
• cista;
• nā maʻi maʻamau. 

Hoʻohui ʻia, hiki i kahi scanner ke kōkua i ka nānā ʻana i kekahi mau ʻano lapaʻau, i loko o ka oncology.

Ma mua o ka hoʻāʻo

Ma mua o ka hoʻokolokolo ʻana, wehe ka mea hoʻomanawanui i nā mea hao a pau. Koi ʻia ka CT scan i ka injection o ka huahana ʻokoʻa: i kēia hihia, hoʻonoho ka radiologist i kahi laina venous (nila e pili ana i kahi catheter) ma ka pā o ka kuʻe lima.

I ka wā o ka hoʻokolokolo

E moe ana ka mea maʻi ma ka pākaukau e neʻe ana i loko o ke apo. Aia i loko o kēia apo he Tube x-ray a me kahi o nā mea ʻike. I ka wā o ka hoʻokolokolo ʻana, pono ke neʻe ʻole ka mea hoʻomanawanui, e moe ana ma ka papa. ʻO ka mea hoʻomanawanui wale nō i loko o ka lumi, akā hiki iā ia, ma o ka microphone, kamaʻilio me ka hui olakino ma hope o ka ninaninau ʻana ma hope o ke aniani kēpau. ʻO ka manawa maʻamau no ka hoʻokolohua ma kahi o ka hapahā o ka hola.

ʻO ke kūlana maʻamau no ka mea hoʻomanawanui e moe ma ke kua me nā lima ma luna o ke poʻo. ʻAʻole ʻeha ka nānā ʻana. I kekahi manawa pono ʻoe e haʻalele i ka hanu ʻana no kekona kekona. Pono nō ia e mālama i ke ala hele a venous no kekahi manawa, inā ʻike ʻia kahi hopena maʻi ma hope o ka hoʻopili ʻana.

Ma hope o ka hōʻike

Hiki i ka mea hoʻomanawanui ke hoʻi me ka home ʻole, e aʻo ʻia ʻo ia e inu nui i mea e hoʻopau koke ai i ka huahana ʻokoʻa. He ʻōlelo aʻoaʻo nui e inu i ʻelua lita o ka wai i ke koena o ka lā.

E `ike :

• ma hope o ka scan, hiki i ka radiologist ke kālailai koke i nā kiʻi a wehewehe koke i nā hopena mua i ka mea maʻi;

• ʻo ka wehewehe ʻana i nā kiʻi i kekahi manawa ke koi i ka manawa hou, ʻo ka hāʻawi hope loa ʻana o nā hopena i hana ʻia ma loko o 24 mau hola hana. Pono paha e koi i ka hana kamepiula ʻelua ʻoi aku a ʻoi paha o ka paʻakikī;

• i nā hihia paʻakikī loa, hiki i nā hopena ke ʻekolu mau lā hana ma hope o ka hoʻokolokolo ʻana.

E hoʻouna ʻia ka hōʻike i ke kauka i kākau ʻia e ka pou, a me nā kiʻi paʻi ʻia a me kahi kiʻi CD-ROM pinepine. 

Inā loaʻa kekahi mau mea kūpono ʻole, hōʻike pinepine ʻia kēia mau mea i nā kiʻi e like me nā kiko, nā nodule, a me nā opacities. ʻIke ʻia ka tomography compulated i nā mea liʻiliʻi ʻuʻuku, ʻoi aku paha ka liʻiliʻi ma mua a i ʻole ka like ʻana me 3 millimeter. Eia nō naʻe, ʻaʻole pono kēia mau mea maʻamau i hōʻailona o ka maʻi ʻaʻai, no ka laʻana. E wehewehe ʻia ka wehewehe i ka mea maʻi e ke kauka, nāna e kūkākūkā i ka ʻike.
