Hongzhi Wang, Sandhitsu Das, John Pluta, Caryne Craige, Murat Altinay, Brian Avants, Michael Weiner, Susanne Mueller, Paul Yushkevich
2010 Lecture Notes in Computer Science  
We propose a simple strategy to improve automatic medical image segmentation.  ...  We apply this methodology on three segmentation problems/methods and show significant improvements for all of them.  ...  By contrast, our contribution lies in proposing the idea of improving the performance of existing segmentation algorithms relative to a specific manual segmentation protocol via learning-based bias correction  ...

This gives a need for identifying specific subgroups of LBP. Modic changes which are visible on Magnetic Resonance Imaging (MRI) might be one of these subgroups.  ...  The percentage of fused motion segments at twelve months was higher for the titanium cages, but the loss of segment height and the range of motion were not different from the PLDLA cages.  ...  A major concern is a possible bias in a longer perspective, since it is based on patients' memory of disability and improvement/deterioration (recall bias).  ...

One patient developed a transient femoral nerve injury.  ...  Conclusion: TLIF is an effective approach for enhancing correction of segmental lordosis. Annular tear on preoperative imaging predicts less postoperative correction.  ...
