New Diagnostic Tool for Far Lateral Lumbar Disc Herniation : The Clinical Usefulness of 3-Tesla Magnetic Resonance Myelography Comparing with the Discography CT
نویسندگان
چکیده
OBJECTIVE To prospectively assess the diagnostic and clinical value of a new technique (3-tesla magnetic resonance myelography, 3T MRM) as compared to computed tomographic discography (disco-CT) in patients with far lateral disc herniation. METHODS We evaluated 3T MRM and disco-CT of 25 patients, whom we suspected of suffering from far lateral disc herniation. Using an assessment scale, 4 observers examined independently both 3T MRM and disco-CT images. We analyzed observer agreement and the accentuation of each image. RESULTS We found complete matching, and observer agreement, between high resolution images of 3T MRM and disco-CT for diagnosing far lateral disc herniation. CONCLUSION We think noninvasive 3T MRM is an appropriate diagnostic tool for far lateral disc herniation as compared to disco-CT.

متن کاملThe validity of upright myelography for diagnosing lumbar disc herniation.
Although computed tomographic (CT) myelography and magnetic resonance imaging (MRI) are used for assessing lumbar disc herniations (LDH), they cannot provide images when patients are standing or walking, whose CT myelograms and MRI images show only slight disc bulging. The purpose of this study was to evaluate the usefulness of upright myelography. We examined by myelography in both an upright ...

Abstract Background: Far lateral discal herniation is an uncommon disorder and is difficult to assess by physical examination alone. This study is designed to define clinical and epidemiological findings and to establish the indications of surgical and medical treatment for FLLDH. Methods: Between 2000 and 2005, a total of 2035 patients with lumbar disc herniation underwent surgical...

an incidence that ranges from 0.26% to 0.30% of all herniated discs (1). Myelography, computed tomography (CT) and magnetic resonance imaging (MRI) are generally used to diagnose intradural lumbar disc herniation (IDLDH), but there can be some differences according to each case. Several studies have reported of a potential association between intradural disc herniation and gas within the spinal...

Preoperative definitive diagnosis of intradural lumbar disc herniation (ILDH) is difficult despite the availability of various neuroradiological investigative tools. We present a case of ILDH diagnosed preoperatively by discography and computed tomography-discography (disco-CT).The patient was a 63-year-old man with acute excruciating right leg pain. Discography and disco-CT demonstrated leakag...
