value of three-dimensional contrast-enhanced magnetic resonance angiography (3D
CE-MRA) in detecting renal artery stenosis (RAS), and in demonstrating segmental
and accessory renal arteries in patients with suspected renovascular hypertension,
taking digital subtraction angiography (DSA) as the reference method. &amp;lt;/span&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p class="MsoNormal" style="border:none;padding:0cm;"&amp;gt; &amp;lt;b&amp;gt;Material and Method &amp;lt;/b&amp;gt; &amp;lt;span lang="tr" xml:lang="tr"&amp;gt;: Twenty five patients underwent 3D CE-MRA
and DSA. Sensitivity, specificity, positive predictive value, and negative predictive
value of CE-MRA in depicting RAS, and sensitivity of the technique in demonstrating
segmental and accessory arteries were calculated. &amp;lt;/span&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p class="MsoNormal" style="border:none;padding:0cm;"&amp;gt; &amp;lt;b&amp;gt;Results: &amp;lt;/b&amp;gt; &amp;lt;span lang="tr" xml:lang="tr"&amp;gt; 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 demonstrating &amp;lt;a&amp;gt;segmental and accessory arteries &amp;lt;/a&amp;gt;were 58% and 91.7%,
respectively. &amp;lt;/span&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p class="MsoNormal" style="border:none;padding:0cm;"&amp;gt; &amp;lt;b&amp;gt;Conclusion: &amp;lt;/b&amp;gt; &amp;lt;span lang="tr" xml:lang="tr"&amp;gt; We found that 3D CE-MRA is a reliable technique
in not only detecting RAS, but in demonstrating accessory arteries as well. However,
according to our results, the value of the method in visualising segmental arteries
is limited. &amp;lt;/span&amp;gt; &amp;lt;/p&amp;gt; &amp;lt;p&amp;gt; &amp;lt;/p&amp;gt;}, number={2}, publisher={MEDİTAGEM Ltd. Şti.}
