He aha nā pilikia o ka radiograph e ʻike ai i ka corona?

Me ka hoʻolaha ʻana o COVID-19 i ka honua holoʻokoʻa, ua hoʻonui ʻia ka hoihoi i ka hana a me ke kūpono o ka radiography chest (CXR) a me ka computed tomography (CT) scans no ka nānā ʻana, ka maʻi a me ka mālama ʻana i nā mea maʻi me ka maʻi COVID-19 i manaʻo ʻia. ʻO ka maikaʻi o ka hilinaʻi ʻana i ka CXR a me CT scans ʻo ko lākou hiki ke ʻike i nā poʻe maʻi me ka kānalua kiʻekiʻe o ka maʻi coronavirus hou a / a i ʻole nā ​​​​maʻi maʻi pneumonia.

Akā ua hōʻike ka International Atomic Energy Commission i ka hoʻonui ʻana o ka tomography computed i ka wā ʻōpio i ka maʻi kanesa ma hope o ke ola. ʻO ka CT scan e like me 300-400 x-rays a he mea maʻamau i nā poʻe maʻi me nā maʻi maʻi o ka maʻi COVID-19 e hana hou i ka CT scans i kēlā me kēia lā ʻekolu, ʻoiai ʻaʻole ia e ʻōlelo ʻia no ka mea e ʻike ʻia i kēlā radiation pōʻino.

Eia nō naʻe, ma muli o ka liʻiliʻi o nā pahu hoʻāʻo, nui nā kikowaena olakino i koho iā CT scan i ke koho mua no ka nānā ʻana a me ka ʻike ʻana iā COVID-19 e pili ana i nā ʻōnaehana hoʻopaʻa inoa ʻo CT. I loko o kekahi manawa, ua ʻōlelo nui ʻia ka nānā ʻana me ka noʻonoʻo ʻole i ko lākou hopena lōʻihi e like me nā hopena ʻino mai ka radiation a me nā maʻi maʻi e pili ana, i nā mea maʻi a me nā limahana mālama ola. I kekahi manawa, hiki i kona hoʻohana ʻana i nā pae weliweli, e hoʻāla ana i ka hoʻopaʻapaʻa nui ma waena o nā kumu kula, nā kauka, a me nā mea noiʻi.

hoʻoheheʻe ionizing

ʻO ka pāhawewe, ma keʻano laulā, kahi e hōʻike ʻia ai ke kino o ka mea maʻi mai nā kukui X, CT scans a me ke kiʻi nuklea he ionizing radiation - nā lōʻihi hawewe kiʻekiʻe e komo i nā molekala a i ʻole nā ​​ʻiʻo e hōʻike i nā ʻāpana a me nā hale o ke kino. Hiki paha ke hōʻino i ka DNA i kēia hoʻoheheʻe ionizing. ʻOiai ke hoʻoponopono nei nā cell i loko o ke kino o ke kanaka i ka hapa nui o nā pōʻino i hana ʻia e ka radiation mai kēia mau scans, hana lākou i ka hana i kekahi manawa me ka pau ʻole, e waiho ana i nā wahi liʻiliʻi o ka "pōʻino".

Nā hoʻololi DNA

ʻO ka hopena, ʻo ia ka hoʻololi ʻana o DNA i hiki ke kōkua i ka maʻi kanesa i nā makahiki ma hope. ʻO ka hapa nui o ka poʻe akamai i ʻike e pili ana i ka pōʻino o ka radiation ionizing mai nā haʻawina lōʻihi o ka poʻe i pakele i ka pahū ʻana o ka 1945 atomic bomb ma Hiroshima a me Nagasaki. Hōʻike kēlā mau haʻawina i kahi piʻi liʻiliʻi akā nui ka nui o ka maʻi kanesa i ka poʻe i ʻike ʻia i nā pahū, me kahi hui o 25000 mau mea i pakele o Hiroshima i loaʻa ma lalo o 50 mSv o ka radiation - kahi nui e ʻike ʻia ai ka mea maʻi i loko o ʻekolu a ʻoi aku ka hana. .

Ma keʻano laulā, pili ka ʻike maoli ʻana i ka radiation i nā kumu he nui, ʻo ia ka mea radiology ponoʻī, ka lōʻihi o ka hoʻokolokolo ʻana, ka nui o ke kino o ka mea maʻi, a me ka naʻau o nā ʻiʻo i hoʻopaʻa ʻia. Hāʻawi ka pahu CT i ka nui ma 100 a 200 mau kiʻi X-ray.

I loko o hoʻokahi makahiki, loaʻa i ka mea maʻamau ma kahi o 3 mSv a ʻo kēlā me kēia CT scan e hāʻawi i 1 a 10 mSv, ma muli o ka nui o ka radiation a me ka ʻāpana o ke kino e hoʻāʻo ʻia. ʻO kahi CT umauma haʻahaʻa haʻahaʻa ma kahi o 1.5 mSv a ʻo ka hoʻāʻo like ʻana ma kahi maʻamau maʻamau ma kahi o 7 mSv. Hiki ke noʻonoʻo ʻia ka haʻahaʻa loa - ʻo ka loaʻa ʻana o kahi maʻi maʻi make no ka mea e loaʻa i ka CT scan ma kahi o 1 i 2000.

Eia nō naʻe, inā ʻaʻohe koho o ka mea maʻi a pono ʻo ia e hana i nā hoʻokolohua he nui i ka manawa pōkole, i kēia hihia e ʻike ʻo ia i ke kauka loea a noi i kāna manaʻo e noʻonoʻo i kahi scan haʻahaʻa haʻahaʻa (ʻoi aku ka maikaʻi o ke kaʻina hana i nā hihia. o nā maʻi maʻi maʻi maʻi me ka mōʻaukala o nā scans i hana ʻia i kēia manawa).

Nā kumuhana ʻē aʻe: 

Pehea ʻoe e hana ai me kāu mea aloha ma hope o ka hoʻi ʻana mai kahi haʻihaʻi?
