Which topographic landmark corresponds to the L2-L3 vertebral level?

The L2-L3 vertebral level corresponds to the inferior costal margin, which is the lower edge of the rib cage. This landmark is clinically significant as it provides an approximate reference point for locating the second and third lumbar vertebrae. Located near the level of the umbilicus, the inferior costal margin helps practitioners identify the right position for lumbar spine imaging and procedures.

The other landmarks listed correspond to different vertebral levels in the body: the superior costal margin is typically associated with the T10 vertebra, the umbilicus corresponds closely to the L3-L4 intervertebral disc, and the xiphoid process relates to the T9-T10 vertebral levels. Understanding these associations is crucial for accurate imaging and procedures in radiologic technology.
