“…2 Variations, including fat saturation, T 2 -weighted turbo-spin echo, turbo fluidalternated inversion recovery, short-tall inversion recovery, and differing contrast media have been suggested to increase sensitivity and specificity of MR imaging. 2,3,11,15 Most practitioners agree that optimal evaluation requires that the patient undergo neuroimaging immediately after contrast administration because the enhancement pattern is best within the first 5 minutes; beyond that, enhancement in the disc can be seen if imaging is delayed (Figs. 1 and 2).…”

“…Gadolinium-enhanced MR imaging is thought to be the best modality to differentiate between the two. 2,3,11,20,25 Computerized tomography discography may also provide additional information. 4 The scar may surround the nerve roots and cause symptoms by means of neural tension, decreased axoplasmic transport, restriction of blood flow, or of venous return.…”

Recurrent lumbar disc herniation is a common disease process. It has been noted to occur in 5 to 15% of cases surgically treated for primary lumbar disc herniation. Outcomes in one series approached those after the initial operations, although this is not the case in the experience of most surgeons. The removal of recurrent lumbar disc herniations requires meticulous surgical technique. Great care is taken to identify the osseous margins of the previous surgical site. Identification and dissection of scar from the dura mater is greatly aided with the use of a microscope.

“…In fact, CT myelography needs a lumbar puncture with contrast administration and is associated with risks of epidural injection, infection, contrast allergy and bleeding [28,29]. However, CT myelography remains the modality of choice for localizing a post-operative CSF leak [30][31][32]. It has been shown that it is able to more accurately define the degree of spinal and neural foraminal stenosis compared with MRI [33].…”

Imaging of post-operative spine in intervertebral disc pathology

et al. 2017

View full text Add to dashboard Cite

This work is an imaging review of spine after surgery with special regard to imaging modality in intervertebral disc pathology. Advances in imaging technology can be evaluated. Depending on the clinical question is asked to the radiologist, it is possible to evaluate post-operative patients with conventional radiology (X-ray), computed tomography and magnetic resonance. Main indications for each technique are analysed. Imaging is important in the diagnosis of many forms of spine pathology and plays a fundamental role in evaluating post-surgical effects of treatments, according to the imaging method which is used, both on spine and on its surrounding tissues (intervertebral discs, spinal cord, muscles and vessels).

“…Previous MRI studies have shown that there is much controversy concerning lumbar spine imaging (25). Fast spin echo (FSE), conventional spin echo (CSE), and proton-density (PD) sequences have been used for imaging degenerative diseases of the lumbar spine (1,4,7,20,25). Furthermore, gradient echo sequences have been evaluated for imaging the lumbar spine (3,18,21).…”
