Kafukufuku wofalitsidwa posachedwapa mu American Journal of Radiology amasonyeza kuti MRI ikhoza kukhala yotsika mtengo kwambiri yojambula zithunzi poyesa odwala omwe akupezeka ku dipatimenti yodzidzimutsa ndi chizungulire, makamaka poganizira za mtengo wapansi.
Gulu lotsogozedwa ndi Long Tu, MD, PhD, kuchokera ku Yale School of Medicine ku New Haven, CT, linanena kuti zomwe zapezazi zingathe kupititsa patsogolo chisamaliro cha odwala pozindikira zikwapu zomwe zimayambitsa. Iwo adanenanso kuti chizungulire ndi chizindikiro cha sitiroko yomwe nthawi zambiri imamangiriridwa ku matenda omwe anaphonya.
Pafupifupi 4% ya kuyendera madipatimenti azadzidzidzi ku United States kumachitika chifukwa cha chizungulire. Ngakhale kuti osachepera 5% mwa milanduyi imakhala ndi sitiroko, ndikofunikira kuti tipewe. Mutu wosasiyanitsa CT ndi mutu ndi khosi CT angiography (CTA) amagwiritsidwa ntchito pozindikira sitiroko, komabe kukhudzidwa kwawo kuli kochepa, kuyima pa 23% ndi 42% motsatira. MRI, kumbali ina, imadzitamandira kwambiri pa 80%, ndipo ma protocol apadera a MRI monga okwera kwambiri, kupeza kwa DWI kwamitundu yambiri kumawoneka kuti akukwaniritsa kukhudzika kwakukulu kwa 95%.
Komabe, kodi mtengo wowonjezera wa MRI ndi wovomerezeka ndi ubwino wake? Tu ndi gulu lake adayang'ana mtengo wa njira zinayi za neuroimaging zowunikira odwala omwe amafika ku dipatimenti yodzidzimutsa ndi chizungulire: kujambula kwa mutu wa CT, mutu ndi khosi CT angiography, MRI ya ubongo, ndi MRI yapamwamba (yomwe imaphatikizapo multiplanar). DWI yapamwamba kwambiri). Gululo linayerekezera ndalama zomwe zimagwiritsidwa ntchito nthawi yayitali komanso zotsatira zomwe zimagwirizanitsidwa ndi kupwetekedwa kwa stroke komanso kupewa kwachiwiri.
Zotsatira zomwe Tu ndi anzake adapeza zinali motere:
MRI yapadera inatsimikizira kuti ndiyo njira yotsika mtengo kwambiri, yopereka ma QALY apamwamba kwambiri pamtengo wowonjezera wa $ 13,477 ndi 0.48 QALYs wamkulu kuposa mutu wosasiyanitsa CT.
Pambuyo pa izi, MRI yachizoloŵezi inapereka chithandizo chotsatira cha thanzi labwino, ndi mtengo wowonjezereka wa $ 6,756 ndi 0.25 QALYs, pamene CTA inapanga ndalama zowonjezera $ 3,952 kwa 0.13 QALYs.
MRI yachizoloŵezi inapezedwa kukhala yotsika mtengo kuposa CTA, yokhala ndi ndalama zowonjezera zosakwana $ 30,000 pa QALY.
Kufufuzaku kunawonetsanso kuti MRI yapadera inali yotsika mtengo kuposa MRI wamba, yomwe, nayonso, inali yotsika mtengo kuposa CTA. Poyerekeza zosankha zonse zamaganizidwe, CT yosagwirizana yokha idawonetsa phindu lochepa kwambiri.
Ngakhale kuti MRI ndi yokwera mtengo yowonjezereka poyerekeza ndi CT kapena CTA, gululi linatsindika zachindunji komanso kuthekera kwake kuchepetsa ndalama zotsika mtengo pokwaniritsa ma QALY akuluakulu.
Ndili wokondwa kugawana kuti LnkMed yakhala m'modzi mwa opanga odalirika kwambiri pazojambula zamankhwala. Timapereka mayankho athunthu azachipatala ndi ntchito pazithunzi za matenda. Tili ndi malo awiri, onse ali ku Shenzhen, chigawo cha pingshan. Chimodzi ndi kupanga contrat media injector, kuphatikizaCT single jekeseni dongosolo,CT wapawiri mutu jakisoni dongosolo, MRI jakisoni dongosolondiAngiography jekeseni system. Ndipo ina ndiyo kupanga syringe ndi machubu.
Tikufunitsitsa kukhala ogulitsa odalirika opangira zithunzi zachipatala.
