Ongororo yakaburitswa munguva pfupi yapfuura muAmerican Journal of Radiology inoratidza kuti MRI ingave ndiyo nzira yekutora mifananidzo inodhura zvakanyanya yekuongorora varwere vanouya kudhipatimendi rekukurumidzira vane dzungu, kunyanya kana tichifunga nezvemitengo yakaderera.
Boka rinotungamirwa naLong Tu, MD, PhD, wekuYale School of Medicine muNew Haven, CT, rakaratidza kuti zvakawanikwa izvi zvinogona kuwedzera kutarisirwa kwevarwere nekuona stroke dziripo. Vakacherechedzawo kuti dzungu chiratidzo chestroke chinowanzo batanidzwa zvakanyanya nekusaonekwa kwechirwere.
Zvinenge 4% zvekushanya kumadhipatimendi ekukurumidzira muUnited States zvinokonzerwa nedzungu. Kunyange zvazvo zvisingasviki 5% zvezviitiko izvi zvine chekuita nesitiroko, zvakakosha kuti zvisadaro. Non-contrast head CT uye head and neck CT angiography (CTA) zvinoshandiswa kuongorora sitiroko, asi kunzwisisika kwadzo kwakaganhurirwa, kuri pa23% uye 42% zvichiteerana. MRI, kune rumwe rutivi, ine kunzwisisika kwakanyanya pa80%, uye ma specialized MRI protocols akadai se high-resolution, multiplanar DWI acquisitions anoita seanowana kunzwisisika kwakanyanya kwe95%.
Zvisinei, mutengo weMRI unotsigirwa here nemabhenefiti ayo? Tu nechikwata chake vakaongorora kushanda kwemari kwenzira ina dzakasiyana dzekuongorora varwere vanosvika mudhipatimendi rekukurumidzira vaine dzungu: CT head imaging isina kusiyana, CT angiography yemusoro nemutsipa, MRI yepfungwa yakajairwa, uye MRI yepamusoro (inosanganisira multiplanar high-resolution DWI). Chikwata ichi chakaenzanisa mari inoshandiswa kwenguva refu nemigumisiro ine chekuita nekuona sitiroko uye kudzivirira kwechipiri.
Zvakawanikwa naTu nevamwe vake zvaive zvinotevera:
MRI yakasarudzika yakaratidza kuva nzira inoshanda zvakanyanya, ichipa maQALY akakwira pamutengo wekuwedzera we $13,477 uye maQALY 0.48 akakura kupfuura non contrast head CT.
Mushure meizvi, MRI yechinyakare yakapa rubatsiro rwepamusoro-soro pahutano, nemutengo wakawedzera we $6,756 uye 0.25 QALYs, nepo CTA yakawedzera mutengo we $3,952 pa 0.13 QALYs.
MRI yakajairika yakawanikwa ichidhura zvishoma pane CTA, uye mutengo wayo unowedzera zvishoma nezvishoma usingasviki $30,000 paQALY imwe neimwe.
Ongororo iyi yakaratidzawo kuti MRI chaiyo yaishanda zviri nani pane MRI yakajairika, iyo, zvakare, yaishanda zviri nani pane CTA. Pakuenzanisa sarudzo dzese dzemifananidzo, noncontrast CT chete yakaratidza bhenefiti shoma.
Kunyangwe mutengo weMRI wakakwira zvishoma nezvishoma zvichienzaniswa neCT kana CTA, timu yakaratidza kuti yakanyatsojeka uye mukana wayo wekuderedza mitengo yakaderera nekuwana maQALY akawanda.
Ndafara kutaura kuti LnkMed yave imwe yemakambani anonyanya kuvimbwa nawo mukugadzira mifananidzo yezvekurapa. Tinopa mhinduro dzakasiyana-siyana dzezvekurapa uye masevhisi mukugadzira mifananidzo yekuongorora. Tine nzvimbo mbiri, dzose dziri muShenzhen, pingshan district. Imwe ndeyekugadzira contrat media injector, kusanganisiraSisitimu yekubaiwa jekiseni rimwe chete reCT,Sisitimu yekubaya misoro miviri yeCT, Sisitimu yekubaiwa jekiseni reMRIuyeSisitimu yekuisa jekiseni reAngiographyUye imwe ndeyekugadzira sirinji nemachubhu.
Tine shungu dzekuva mutengesi wezvigadzirwa zvemifananidzo yekurapa zvinovimbwa newe.
