Abstract

AIM: The aim of this study was to evaluate the use of Resovist in perfusion-weighted imaging (PWI) of rat hyperacute cerebral infarction. MATERIAL and mETHods: 30 Wistar rats were randomly divided into 2 groups. Group A was intravenously injected with 8 μmol Fe/kg body weight of Resovist, whilst Group B was injected with 0.2 mmol/kg body weight of Gd-DTPA. These dosages were chosen to provide comparable maximum signal changes in normally perfused brain. CBV, CBF and MTT parameter profiles were obtained for the core diseased region and the penumbra of brain ischemia and compared between the two groups. These results were then correlated with pathological findings and TTC staining. RESULTS: In our rat stroke model, signal-time curves were similar between Gd-DTPA and Resovist, both in the core area with severe ischemia and in the penumbra area with moderate ischemia. The CBV, MTT, and TTP values of PWI for ischemic penumbra in Groups A and B showed no statistical disparity. CONCLUSION: The efficacy of Resovist in MR PWI is similar to Gd-DTPA in the diagnosis of perfusion reduction in the rat stroke model.

Özet

AMAÇ: Bu çalışmanın amacı, sıçan hiperakut serebral enfarktüsünde perfüzyon ağırlıklı görüntülemede Resovist kullanımını değerlendirmekti. YÖNTEM ve GEREÇLER: 30 Wistar sıçanı olarak 2 gruba bölündü. Grup Aya intravenöz olarak 8 μmol Fe/kg vücut ağırlığı Resovist intravenöz olarak enjekte edilirken Grup Bye 0,2 mmol/kg vücut ağırlığı Gd-DTPA enjekte edildi. Bu dozlar normalde perfüze olan beyinde karşılaştırılabilir maksimum sinyal değişiklikleri oluşturmak üzere seçildi. CBV, CBF ve MTT parametre profilleri merkez hastalıklı bölge ve beyin iskemisi penumbrası için elde edilip iki grup arasında karşılaştırıldı. Bu sonuçlar sonra patolojik bulgular ve TTC boyaması ile korele edildi. BULGULAR: Sıçan inme modelimizde sinyal zaman eğrileri hem şiddetli iskemili merkez bölge hem orta derecede iskelemili penumbra bölgesinde Gd-DTPA ve Resovist arasında benzerdi. CBV, MTT ve TTP değerleri perfüzyon ağırlıklı görüntülemede iskemik penumbra bölgesinde A ve B Grupları açısından istatistiksel fark göstermedi. SONUÇ: Resovistin MR perfüzyon ağırlıklı görüntülemede etkinliği sıçan inme modelinde perfüzyon azalması tanısı açısından Gd-DTPA ile benzerdir.
