BACKGROUND AND PURPOSEThe high variability of CSF volumes partly explains the inconsistency of anesthetic effects, but may also be due to image analysis itself. In this study, criteria for threshold selection are anatomically defined.
METHODST2 MR images (n = 7 cases) were analyzed using 3‐dimentional software. Maximal–minimal thresholds were selected in standardized blocks of 50 slices of the dural...
A 3D model of lumbar structures of anesthetic interest was reconstructed from human magnetic resonance (MR) images and embedded in a Portable Document Format (PDF) file, which can be opened by freely available software and used offline. The MR images were analyzed using a specific 3D software platform for biomedical data. Models generated from manually delimited volumes of interest and selected MR...
