Cervical Spine Surgery with Intraoperative CT Imaging System using A Self-Moving Helical CT Scanner Gantry enabling Intraoperative 3D Imaging

Effective dose of intraoperative 3D imaging in spine surgery

3D-imaging was introduced in 1999. The first publications described the image quality of the 3D-images as comparable to a CT in small joints and sufficient for intraoperative control at the spine and the pelvis. It was initially not possible to visualize the shoulder region. The quality was insufficient for diagnostic purposes at spine and pelvis [1, 2]. The image quality of the CT is still the...

Efficacy of Preoperative CT Imaging in Posterior Cervical Spine Surgery

The aging of society has increased the number of cases of cervical spine disorder. Improved surgery, including cervical laminoplasty for posterior decompression, has resulted in favorable outcomes in many cases (Hirabayashi et al. 1981, Kurokawa et al.1983). Instrumentation such as pedicle screws used in lumbar surgery has also been developed for treatment of cervical deformities caused by agin...

Total navigation in spine surgery; a concise guide to eliminate fluoroscopy using a portable intraoperative-CT 3D navigation system

Intraoperative diffusion imaging on a 0.5 Tesla interventional scanner.

Intraoperative line scan diffusion imaging (LSDI) on a 0.5 Tesla interventional MRI was performed during neurosurgery in three patients. Diffusion trace images were obtained in acute ischemic cases. Scan time per slice was 46 seconds and 94 seconds, respectively, for diffusion tensor images. Diagnosis of acutely developed vascular occlusion was confirmed with follow-up scans. White matter tract...

Traction device to improve CT imaging of lower cervical spine.

CT demonstration of lower cervical spine detail is often limited by a streak artifact created by the shoulders within the tomographic field of view (Fig. 1). The patient may be instructed to hold the shoulders low; however, this position is difficult to maintain without moving throughout the often lengthy examination. Various methods for achieving optimal CT cervical spine images have been desc...
