Volume rendering technique (vrt) for planning and learning cranio-vertebral junction (cvj) surgeries: technical note.

Segmentation Assisted Object Distinction for Direct Volume Rendering

Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

Postero-lateral Approach to the Cranio-vertebral Junction: How, When and Why?

To date the postero-lateral approach represents the best strategy for the surgery of the intradural ventro-lateral lesions of the cranio-vertebral junction (CVJ). Over the years, several authors have proposed different variations of this technique, but the principle on which all are based is the ability to access to the ventral region of the brainstem and high cervical cord with minimum retract...

Posterior occipito cervical decompression with fixation and fusion in Cranio vertebral junction compression

Objective To find out the clinical outcome of posterior decompression with occipitocervical fixation and fusion in patients with Craniovertebral junction instability. Methods Eighty consecutive patients of cranio vertebral junction (CVJ) compression were treated in the department of neurosurgery, Jinnah Postgraduate Medical Centre (JPMC), Karachi over a period of 05 years from 1st January 201...

Transoral Surgery for Cranio-cervical Junction Compression

Quantification of Pediatric Cervical Spine Growth at the Cranio-Vertebral Junction

OBJECTIVE The purpose of this study was to investigate morphological change at the craniovertebral junction (CVJ) region using computed tomography. METHODS A total of 238 patients were included in this study, and mean age was 47.8±21.3 months. Spinal canal diameter, Power's ratio, McRae line, antero-posterior C1 ring height, atlantoaxial joint space, C2 growth, epidural space from the dens (M...
