Finite Element Modeling of the Human Lumbar Spine

Finite element (FE) numerical simulation is an effective tool for analyzing phenomena that cannot be clarified by experimental methods, like most of the biomechanical processes, for example the age-related spinal degeneration processes. Moreover, numerical simulation techniques have the potential to reduce costs and to save time during the development of new effective spinal treatment methods o...

Angiolipoma on the Lumbar Spine

Angiolipomas are composed of mature adipose tissue and blood vessels. Spinal angiolipomas are rare benign tumors with a good prognosis, and most symptoms are due to progressive compression of the spinal cord and root. The treatment of choice is total resection without any additional therapy. We report a case of an epidural angiolipoma on the lumbar spine in a 69-year-old man with weakness of th...

Investigation of the Entrance Surface Dose and Dose to Different Organs in Lumbar Spine Imaging

Background: Dose assessment using proper dosimeters is especially important in radiation protection optimization and imaging justification in diagnostic radiology.Objective: The aim of this study is to obtain the Entrance Skin Dose (ESD) of patients undergoing lumbar spine imaging using two thermoluminescence dosimeters TLD-100 (LiF: Mg, Ti) and GR-200 (LiF: Mg, Cu, P) and also to obtain the ab...
