Abstract

Objectives: In this study we aimed to evaluate any reliable marker on MRI studies for vertebral enumeration without any need to whole spine imaging.Background: Lumbosacral transitional vertebra (LSTV) is an anatomical variation that is mostly incidentally detected in routine spinal magnetic resonance imaging (MRI) studies. Its detection and awareness have great importance especially for planning of an interventional procedure. Methods:We retrospectively evaluated 899 lumbar MRI examinations. Vertebral levels of aortic bifurcation (AB), celiac trunk (CT), superior mesenteric artery (SMA), right renal artery (RRA), left renal artery (LRA), inferior vena cava (IVC) confluence), 12th costovertebral junction and the origin level of psoas muscle were evaluated.
