“…Appropriate use of oblique section can improve MR image quality and diagnostic value [8]. By a simple modification of an existing pulse sequence program, oblique images of CS can easily be obtained and spatial orientation can be established so as to asses pertaining foramen and root [9]. MR imaging is considered the gold standard for visualizing soft tissue, whereas CT is still applied for identifying bony abnormalities.…”

ÖzetBu çalışmanın amacı, 45 derece oblik açıda çekilmiş manyetik rezonans (MR) gö-rüntülemenin karmaşık servikal patolojilerde ve ameliyat sonrası değerlendirme-deki faydasını vurgulamaktır. 2002 ve 2007 yılları arasında dejeneratif servikal omurga bozukluklarından dolayı 252 hastaya cerrahi müdahalede bulunduk. Bunların takiplerinde bazı hastalar devam eden kök ağrısından dolayı servikal spinal MR ile değerlendirildiler. Burada, servikal oblik MRın etkinliğini ortaya koymak için dört vaka takdim edilecektir. İlk vaka, ameliyat öncesi dönemde de cerrahi kararında oblik MR görüntülerinin önemini vurgulamaktadır. İkinci vakada, oblik gö-rüntülere dayanarak reoperasyona karar verilmiştir. Üçüncü vaka implantların neden olduğu artefaktlara, ve bu durumda 45 derece oblik MR görüntülerinin faydasına dikkati çekmektedir. Dördüncü olguda, servikal implanta rağmen oblik kesitlerde foramenlerin sağlıklı değerlendirilebildiği görülmektedir. Ameliyat sonrası dönemde, alışılmış MR görüntülerinde herhangi bir patolojiye atfedilemeyen devam eden kök ağrısı olan servikal implantlı hastalar, oblik servikal MR'dan fayda sağlayabilirler. case emphasizes its importance also in decision of treatment in the preoperative period. In the second case, reoperation was decided regarding oblique MR images. Third case draws attention to the artifacts due to implants and efficacy of 45° oblique MR images in such circumstances. In the fourth case despite the implants, foramina could be visualized clearly in oblique cuts. Patients with postoperative radiculopathy with implants that could not be ascribed to any pathology visible in the conventional MR sequences might benefit from oblique MR imaging. In this study, it has been aimed to depict the efficacy of 45° oblique MR images in selected patients for delineating foraminal pathology via sample cases particularly in the postoperative period.

A straightforward method for calculating maximum gradient amplitudes for the frequency-encoding, phase-encoding, and section-select functions in oblique magnetic resonance (MR) imaging is presented. The calculated amplitude values depend on the prescribed angulation and on which of the three functions are simultaneously active. The derived expressions are optimal in most cases, and when not optimal, they still offer substantial improvement over calculations that do not incorporate angular information. Both matrix-based and geometric interpretations are presented.
