III. Pehea e hana ai ka mīkini CT Scan?

ʻO ke kumu hana o kahi mīkini scan CT e hoʻohuli a puni nā kukui X. Eia ka wehewehe ʻanuʻu maʻalahi o ka hana ʻana o ka mīkini scan CT:

1. X-ray Tube Rotation

Hoʻonoho ʻia ka mea maʻi ma luna o kahi pākaukau kaʻa e neʻe mālie i loko o kahi puka pōʻai o ka mīkini scan CT. Hoʻololi mau ka paipu X-ray a puni ke kino o ka mea maʻi, e hoʻopuka ana i nā kukui X.

2. ʻIke X-ray

ʻO nā kukui X i hoʻokuʻu ʻia mai ka pahu X-ray e hele i ke kino. Hoʻopili ʻia kēia mau kukui X e nā ʻiʻo like ʻole ma nā ʻano like ʻole (ʻoi aku ka nui o nā ʻiʻo X-ray). ʻO kahi pūʻulu o nā mea ʻike, i hoʻonoho ʻia ma ka ʻaoʻao ʻē aʻe o ka paipu X-ray, e hopu i nā kukui X e hele ana ma ke kino.

3. Hoʻololi ʻikepili

Hoʻololi ka pūʻulu o nā mea ʻike i kēia mau hōʻailona X-ray i nā hōʻailona uila, a laila hoʻouna ʻia i kahi kamepiula. Loaʻa i ka lolouila kēia mau hōʻailona uila a hoʻoponopono iā lākou e hana i nā kiʻi kikoʻī kikoʻī a i ʻole nā ​​''āpana.'

4. Hana Hou Kiʻi 3D

Hoʻohui ʻia kēia mau ʻāpana pākahi i kahi kiʻi ʻekolu-dimensional o ke kino, e ʻae ana i ka radiologist e nānā hohonu i nā ʻano a me nā ʻiʻo.

 

IV. Nā Pōmaikaʻi Nui o nā Mīkini CT Scan

Hāʻawi nā mīkini scan CT i nā pono koʻikoʻi e hoʻolilo iā lākou i mea pono pono i ka mālama olakino hou. ʻO kekahi o nā pōmaikaʻi koʻikoʻi:

1. Kiʻi hoʻoholo kiʻekiʻe

ʻO kekahi o nā mea maikaʻi loa ʻo ko lākou hiki ke hāʻawi i nā kiʻi hoʻonā kiʻekiʻe. Hiki iā lākou ke ʻike i nā kikoʻī anatomical liʻiliʻi loa a me nā mea ʻino. No ka laʻana, i ka nānā ʻana i ka maʻi kanesa, hiki i nā mīkini scan CT ke ʻike i nā nodule liʻiliʻi e like me kekahi mau millimeters, ʻaʻole hiki ke loaʻa me nā mīkini X-ray maʻamau. ʻO kēia mau kiʻi hoʻonā kiʻekiʻe e hiki ai i nā kauka ke nānā pono i nā hale o loko o nā kino, e kōkua ana i ka hanaʻana i nā hōʻailona kūpono o nāʻano likeʻole.

2. Ka wikiwiki a me ka pono

ʻO nā kiʻi CT, hana maʻamau i loko o nā minuke wale nō, ʻoi aku ka wikiwiki e hoʻohālikelike ʻia i kekahi mau ʻano kiʻi e like me MRI. He pōmaikaʻi nui ia, ʻoi aku hoʻi no nā poʻe maʻi i paʻakikī i ka noho ʻana no ka manawa lōʻihi a i ʻole ka poʻe me kekahi mau maʻi maʻi.

3. ʻIke piha

Hiki i nā mīkini scan CT ke hana i nā kiʻi cross-sectional e hāʻawi i kahi ʻike piha loa o nā hale o loko o ka mea maʻi, e kōkua ana i nā kauka e nānā i nā wahi paʻakikī, e like me nā kīʻaha koko, nā iwi, a me nā ʻāpana, no ka ʻike pololei ʻana. ʻO ka mea ʻē aʻe, hiki ke hoʻohui ʻia kēia mau kiʻi keʻa i loko o kahi kumu hoʻohālike ʻekolu. Hoʻohana pinepine ʻia kēia no ka hoʻolālā ʻana i nā ʻokiʻoki a me nā biopsies. ʻO keʻano hoʻohālikeʻekolu ke kōkua i nā kauka e nānā i kahi kūpono o nā meaʻino, e hōʻoia i ka hanaʻana o nā kaʻina hana me ka pololei.

 

V. Nā Lapaʻau Lapaʻau maʻamau o nā mīkini CT Scan

ʻO nā mīkini CT scan he mau mea pono loa ia i nā ʻano loea lapaʻau. ʻO kekahi o nā mea hoʻohana maʻamau:

1. ʻIke a me ka nānā ʻana i ka maʻi maʻi

I ka nānā ʻana i ka maʻi kanesa, hoʻohana pinepine ʻia nā mīkini CT scan e ʻike i ka maʻi kanesa ma nā ʻāpana like ʻole, e like me ke akemāmā, ate, pancreas, a me nā puʻupaʻa. I ka nānā ʻana i ka maʻi kanesa a i ʻole ma hope o ka mālama ʻana, hoʻohana ʻia nā mīkini scan CT e nānā i ka holomua o ka maʻi kanesa, e kōkua ana i nā kauka e loiloi i ka emi ʻana a i ʻole ka laha ʻana o ka maʻi maʻi.

2. ʻIke ʻana i ka maʻi maʻi maʻi

ʻO CT angiography (CTA) kahi ʻano kūikawā o ka CT imaging i hoʻohana ʻia e nānā i ke olakino cardiovascular. Kōkua ia i ka poʻe cardiologists e ʻike i ke ʻano o ka naʻau, nā paʻa i loko o nā aʻa coronary, a me nā aneurysms me ka ʻole o ka pono o ka hōʻoki invasive.

3. ʻIke ʻana i ka maʻi neurological

I loko o ka neurology, hoʻohana ʻia nā mīkini scan CT e ʻike i nā ʻano ʻano like ʻole e pili ana i ka lolo a me ka ʻōnaehana o ke kikowaena, e like me ka hemorrhages o ka lolo, ka hahau ʻana, ka lolo lolo, ka traumatic brain injury (TBI). Hiki iā lākou ke kōkua i nā neurologist e hoʻokaʻawale i nā ʻano maʻi nui (e laʻa, ischemic stroke a me hemorrhagic stroke), e nānā i ka nui o nā maʻi (e laʻa, nā maʻi maʻi maʻi a me nā maʻi maʻi ʻino), a hoʻolālā i nā lāʻau lapaʻau kūpono.

4. ʻIke ʻana i ka maʻi orthopedic

I nā orthopedic, hoʻohana pinepine ʻia nā mīkini scan CT e ʻike i nā pilikia me nā iwi, e like me ka haʻihaʻi ʻana o ka iwi, nā maʻi hui, nā maʻi spinal, a i ʻole nā ​​maʻi iwi (ma mua a me ka metastatic). Kōkua pū lākou i ka hoʻolālā ʻana i nā ʻokiʻoki orthopedic a me ka nānā ʻana i ke kaʻina hana ho'ōla.

5. Ka ʻeha a me ka mālama ʻana i ka pilikia

I loko o ka lumi ulia pōpilikia, kahi i koʻikoʻi ai kēlā me kēia kekona, lawelawe nā mīkini scan CT ma ke ʻano he mea hana diagnostic koʻikoʻi no nā hihia trauma. Hiki iā lākou ke ʻike koke i nā pōʻino weliweli i ke ola i ʻike ʻole ʻia ma waho, e like me ke kahe koko o loko, ka pōʻino o ke kino, nā haʻihaʻi, nā pilikia neurological, a me nā pilikia o ka ʻōpū.

 

VI. ʻO nā pilikia a me nā noʻonoʻo o nā mīkini CT Scan

ʻOiai he mea maikaʻi loa ka mīkini scan CT i nā diagnostics lapaʻau, loaʻa iā lākou kekahi mau pilikia, pili nui i ka hoʻolaha ʻana i ka radiation. Eia kekahi mau manaʻo.

1. Hōʻikeʻike ʻia ka Radiation

ʻO ka hoʻohana ʻana i nā mīkini kiʻi CT e huli holoʻokoʻa a puni nā kukui X, ʻo ia ke ʻano o ka radiation ionizing. Hiki i ka Ionizing radiation ke hoʻopōʻino i ka DNA i loko o nā pūnaewele, a ma nā hihia kakaʻikahi hiki ke alakaʻi i ka piʻi nui ʻana o nā pilikia olakino pili i ka radiation, e like me ka maʻi kanesa, i ka wā lōʻihi. ʻOiai he haʻahaʻa ka nui o ka radiation mai kahi CT scan hoʻokahi, hiki i nā scan hou a pono ʻole ke hoʻonui i ke ola o ke kanaka i ka radiation. Eia nō naʻe, ʻoi aku ka nui o nā pono o ka CT scans ma mua o nā pilikia, ʻoiai inā pono lākou no ka ʻike ʻana a i ʻole ka mālama ʻana i nā kūlana koʻikoʻi.

2. Nā Lehulehu Kūikawā

Pono kekahi mau pūʻulu o nā kānaka i ka nānā kūikawā i ka wā e pili ana i ka CT scans. ʻO nā wāhine hāpai ke kumu nui. ʻO ka manaʻo nui, ʻo ka radiation mai ka CT scans hiki ke hoʻopilikia i ka ulu ʻana o ka fetus, ʻoi aku hoʻi i ka wā o ka trimester mua. Hiki ke alakaʻi i ka hoʻoheheʻe ʻana i ka radiation i nā kīnā hānau, nā palena o ka ulu ʻana, nā maʻi maʻi ʻōpiopio, a i ʻole ka hāʻule ʻana i kekahi mau hihia. No laila, inā ʻaʻole i ʻoi aku ka maikaʻi o nā pōmaikaʻi ma mua o nā pilikia i kahi kūlana weliweli i ke ola no ka makuahine a i ʻole ka pēpē, pono i nā wahine hāpai ke pale i ka CT scans, ʻoi aku ka nui o ka ʻōpū a i ʻole ke pelvis. Hoʻohana mau ʻia nā ʻano hana kiʻi ʻē aʻe, e like me ke ultrasound a i ʻole MRI, no nā maʻi hāpai.

3. Nā Agena Kūkākūkā

Hoʻohana ʻia nā mea ʻokoʻa (ʻulaʻula) i kekahi mau CT scans e hoʻomaikaʻi i ka ʻike ʻana o nā kīʻaha koko, nā ʻāpana, a me nā ʻiʻo ʻano ʻino. ʻOiai he mea koʻikoʻi lākou no ka hoʻomaikaʻi ʻana i ka pololei diagnostic, pono lākou e nānā pono ma muli o nā pilikia. ʻO nā mea e hopohopo nui ai, ʻo ia ka hopena maʻi, hiki ke hoʻomaka mai ka ʻuʻu haʻahaʻa a hiki i ka anaphylaxis koʻikoʻi, a me ka ʻawaʻawa o ka puʻupaʻa - ʻoi loa i nā poʻe maʻi me ka pōʻino o ka renal. No laila, no ka mālama pono ʻana, pono e mālama mua ʻia kahi hoʻomaʻamaʻa ʻana, e pili ana i ka nānā ʻana i ka mōʻaukala olakino o ka mea maʻi no nā allergies, asthma, hana maʻi maʻi, diabetes, a me nā lāʻau lapaʻau o kēia manawa.

 

VII. Ka hopena

ʻO nā mīkini CT scan ka pōhaku kihi o ka lāʻau diagnostic hou. Hoʻopuka lākou i nā kiʻi kikoʻī, ʻāpana ʻāpana o nā hale i loko o ke kino, e kōkua ana i nā kauka e ʻike a mālama i nā ʻano maʻi like ʻole, mai ka trauma a hiki i ke kanesa. ʻOiai nā pilikia e pili ana i ka hoʻolaha ʻana i ka radiation, ʻo ka maikaʻi o nā mīkini scan CT ma ke ʻano o ka hoʻonā kiʻekiʻe, ka wikiwiki wikiwiki, a me ka ʻike piha e lilo ia i mea pono i ka mālama olakino.
