Ngaba i-MRI yeyona ndlela ingabizi kakhulu yokuvavanya izigulane ezinesiyezi?

Uphononongo olusandula ukupapashwa kwi-American Journal of Radiology lubonisa ukuba i-MRI isenokuba yeyona ndlela yokulinganisa engabizi kakhulu yokuvavanya izigulana ezifika kwicandelo longxamiseko ezinesiyezi, ingakumbi xa kujongwa iindleko ezisezantsi.

Iqela elikhokelwa nguLong Tu, MD, PhD, waseYale School of Medicine eNew Haven, CT, licebise ukuba ezi ziphumo zinamandla okuphucula ukhathalelo lwezigulane ngokuchonga isifo sohlangothi esingaphantsi. Bakwaqaphele ukuba isiyezi luphawu lwesifo sohlangothi oluqhele ukunxulunyaniswa nokuxilongwa okungachanekanga.

Phantse i-4% yokutyelela amasebe angxamisekileyo eMelika ibangelwa kukuziva ngathi kukho isiyezi. Nangona zingaphantsi kwe-5% zezi meko zibandakanya isifo sohlangothi esingaphantsi, kubalulekile ukuyisusa loo nto. I-CT yentloko engangqinelaniyo kunye ne-CT angiography yentloko nentamo (CTA) zisetyenziselwa ukuxilonga isifo sohlangothi, kodwa uvakalelo lwazo lulinganiselwe, lukwi-23% kunye ne-42% ngokulandelelana. I-MRI, kwelinye icala, inesimo sovakalelo esiphezulu kwi-80%, kwaye iiprotokholi ze-MRI ezikhethekileyo ezifana nokufunyanwa kwe-DWI enesisombululo esiphezulu zibonakala zifikelela kwinqanaba eliphezulu lovakalelo lwe-95%.

Nangona kunjalo, ngaba iindleko ezongezelelweyo ze-MRI ziyathetheleleka ngenxa yeenzuzo zayo? UTu kunye neqela lakhe bahlolisise ukusebenza kakuhle kweendlela ezine ezahlukeneyo ze-neuroimaging zokuvavanya izigulane ezifika kwicandelo likaxakeka zinesizungu: i-CT head imaging engeyiyo i-contrast, i-CT angiography yentloko nentamo, i-MRI yobuchopho eqhelekileyo, kunye ne-MRI ephucukileyo (equka i-multiplanar high-resolution DWI). Iqela lenze uthelekiso lweendleko zexesha elide kunye neziphumo ezinxulumene nokufunyaniswa kwestroke kunye nokuthintela okwesibini.

Iziphumo ezifunyenwe nguTu kunye noogxa bakhe bezilandelayo:

I-MRI ekhethekileyo iyeyona ndlela ingabizi kakhulu, ivelise ii-QALY eziphezulu ngexabiso elongezelelweyo le-$13,477 kunye nee-QALY ezingama-0.48 ezingaphezulu kune-non-contrast head CT.

Emva koku, i-MRI eqhelekileyo ibonise inzuzo yezempilo elandelayo ephezulu, ngexabiso elonyukileyo le-$6,756 kunye ne-0.25 QALYs, ngelixa i-CTA ifumene iindleko ezongezelelweyo ze-$3,952 kwi-0.13 QALYs.

I-MRI eqhelekileyo ifunyenwe ingabizi kakhulu kune-CTA, kwaye iindleko zayo ziphantsi kwe-$30,000 nge-QALY nganye.

Uhlalutyo lukwabonise ukuba i-MRI ekhethekileyo yayingabizi kakhulu kune-MRI eqhelekileyo, nto leyo, eyayingabizi kakhulu kune-CTA. Xa kuthelekiswa zonke iindlela zokuthatha imifanekiso, i-CT engangqinelaniyo yodwa ibonise inzuzo ephantsi.

Nangona iindleko ze-MRI ziphezulu xa kuthelekiswa ne-CT okanye i-CTA, iqela ligxininise ukucaca kwayo kunye nokukwazi kwayo ukunciphisa iindleko ezisezantsi ngokufezekisa ii-QALY ezinkulu.

Ndonwabile ukwabelana ukuba i-LnkMed iye yaba ngomnye wabavelisi abathembekileyo kwimifanekiso yezonyango. Sinikezela uluhlu olupheleleyo lwezisombululo zonyango kunye neenkonzo kwimifanekiso yokuxilonga. Sineendawo ezimbini, zombini zikwisithili saseShenzhen, ePingshan. Enye kukwenza i-contrat media injector, kuqukaInkqubo ye-CT single injection,Inkqubo yokujova iintloko ezimbini ze-CT, Inkqubo yokujova i-MRIkwayeInkqubo yokujova i-AngiographyEnye kukuvelisa isirinji kunye neetyhubhu.

Silangazelela ukuba ngumthengisi wakho othembekileyo weemveliso zemifanekiso yezonyango.
