Abstract :

<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%;tab-stops:9.0pt .25in 22.5pt"><span style="font-size:&#10;14.0pt;line-height:200%">The basilar artery terminates by dividing into two posterior cereal anteries at a veriable level but most frequently in the interpeduncular cistern, behind the dorsum sallae.Each posterior cereal arteries supplies respective occipital lobe of the cereum. The present study is designed to know the diameter and variations of posterior cereal artery included MR Angiographies of 132 patient.<o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%;tab-stops:9.0pt .25in 22.5pt"><span style="font-size:&#10;14.0pt;line-height:200%"><span style="mso-spacerun:yes">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>The diameter of posterior cereal artery measure 2 mm away from its origin and observe variation of artery. The mean diameter of posterior cereal artery of all age group are Right - 1.5 mm, and Left - 1.5 mm (2) below age group 60 year- Right &ndash; 1.6 mm and Left &ndash; 1.6 mm (3) age above 60 year &ndash; Right &ndash; 1.7 mm and Left- 1.7 mm. Variations in posterior cereal arteries are Hypoplastic 1.89% and Absence 4.03%. The need for the diamensional data for diameter of artery and variations by neurosurgeons and radiologist as well as researchers but no comprehensive measurements have been published especially, in the Indian data.<o:p></o:p></span></p>
