The aim of this study is to evaluate how accurately transitional vertebrae can be identified using routinely employed clinical imaging methods, including thoracolumbar direct radiography and lumbar MRI with axial and sagittal sequences. The study also seeks to determine how anatomical markers commonly used in the literature for vertebral level identification correspond to vertebral levels in the Turkish population, and whether a new potential relationship between these anatomical markers can be identified to improve accurate vertebral numbering. Additionally, the study will assess the relationship between thoracolumbar transitional vertebra (TLTV) and lumbosacral transitional vertebra (LSTV) variations, and ultimately aims to provide new data to determine which imaging-based approach offers the highest diagnostic accuracy.
