AB  - Aim: The aim of our study was to evaluate the diagnosticvalue of three-dimensional contrast-enhanced magnetic resonance angiography (3DCE-MRA) in detecting renal artery stenosis (RAS), and in demonstrating segmentaland accessory renal arteries in patients with suspected renovascular hypertension,taking digital subtraction angiography (DSA) as the reference method. Material and Method: Twenty five patients underwent 3D CE-MRAand DSA. Sensitivity, specificity, positive predictive value, and negative predictivevalue of CE-MRA in depicting RAS, and sensitivity of the technique in demonstratingsegmental and accessory arteries were calculated.Results: For detecting RAS, the sensitivity, specificity,positive predictive value, and negative predictive value of 3D CE-MRA were; 100%,97.8%, 87.5%, and 100%, respectively. The sencitivity of the technique in demonstratingsegmental and accessory arteries were 58% and 91.7%,respectively. Conclusion: We found that 3D CE-MRA is a reliable techniquein not only detecting RAS, but in demonstrating accessory arteries as well. However,according to our results, the value of the method in visualising segmental arteriesis limited.

N2  - Amaç: Çalışmamızın amacı, digital subtraction angiography(DSA) tekniğini referans metod alarak, üç boyutlu kontrastlı manyetik rezonans anjiyografi(3D CE-MRA) tekniğinin, renal arter stenozu (RAS) tanısındaki ve segmental ve aksesuarrenal arter görüntülemesindeki değerini saptamak idi. Gereç ve Yöntem: Yirmi beş hastaya 3D CE-MRA ve DSA tetkikleriuygulandı. CE-MRA tekniğinin RAS tanısındaki sensitivite, spesifisite ve pozitifve negatif kestirim değerleri ile tekniğin segmental ve aksesuar renal arter görüntülemedekisensitivite değerleri hesaplandı.Bulgular: RAS tanısında CE-MRA tekniğinin sensitivite,spesifisite, pozitif ve negatif kestirim değerleri, aynı sıra ile; %100, %97,8,%87,5, ve %100 olarak hesaplandı. Tekniğin segmental ve aksesuar renal arter görüntülemedekisensitivite değerlerinin, aynı sıra ile; %58 ve %91,7 olduğu saptandı. Sonuç: 3D CE-MRA tekniğinin, sadece renal arter stenozutanısında değil, aksesuar arterlerin görüntülemesinde de güvenilir olduğu saptandı.Ancak çalışmamızın sonuçlarına göre, tekniğin segmental arter görüntülemesindekideğeri sınırlıdır.
