Abstract

AIM: The aim of this study was to evaluate the role of intravascular virtual MR endoscopy in the planning of correct surgical clipping of the aneurysm neck. MATERIAL and METHODS: A total of 36 aneurysms were detected by using magnetic resonance angiography (MRA) in thirty patients. Intravascular virtual MR endoscopy is a realistic 3-dimensional simulation of intravascular structures that is generated by postprocessing of MRA maximum-intensity projection images. The images were evaluated by two neuroradiologists, in terms of image quality via qualitative analysis of MRA and intravascular virtual MR endoscopy of the orifice of the aneurysm neck, as well as the relationship of the main and bifurcating arteries with the orifice of the aneurysm. The readers were fully blinded. Mann-Whitney U test was used to compare the differences in mean scores for each reader between these two groups. RESULTS: Based on the scoring system, evaluating image quality using qualitative analysis, both readers found the mean scores to be 3.82 ± 0.52 and 3.91 ± 0.72 for intravascular virtual MR endoscopy, and 2.97 ± 0.71 and 2.89 ± 0.83 for MRA, which was statistically different (p<0.001). CONCLUSION: Intravascular virtual MR endoscopy may provide useful knowledge in the proper the surgical clipping of the aneurysm neck.

Özet

AMAÇ: Bu çalışmanın amacı, anevrizma boynunun doğru cerrahi kliplenmesinin planlanmasında intravasküler sanal MR endoskopinin rolünü değerlendirmektir. YÖNTEM ve GEREÇLER: 30 hastada 36 anevrizma magnetik rezonans anjiyografi (MRA) kullanılarak ortaya çıkarıldı. İntravasküler sanal MR endoskopi, MRA maximum-intensity projeksiyon görüntülemenin işlenmesinden üretilen intravasküler yapıların gerçekçi 3 boyutlu simülasyonudur. İki nöroradyolog tarafından MRA ve intravasküler sanal MR endoskopide anevrizma boynunun orifisi ve anevrizmanın orifisi ile bifurkasyon arter ve ana arterin ilişkisi kalitatif analiz vasıtasıyla görüntü kalitesi açısından değerlendirildi. İki okuyucu tamamen bağımsızdı. Bu iki grup arasındaki her bir okuyucu için ortalama puan farkının anlamlılığına Mann-Whitney testi ile karşılaştırıldı. BULGULAR: Kalitatif analiz kullanılarak görüntü kalitesini puanlama sistemine göre değerlendirilmesinde her iki okuyucu intravasküler sanal MR endoskopi için 3.82 ± 0.52 ve 3.91 ± 0.72; MRA için 2.97 ± 0.71 ve 2.89 ± 0.83 ortalama skora sahipti ve bu fark istatistiksel olarak anlamlıydı (p<0.001). SONUÇ: İntravasküler sanal MR endoskopi anevrizma boynunun uygun cerrahi kliplenmesinde faydalı bilgi sağlayabilir.
