In the present study 11 surgically confirmed patients with the clinico-radiological diagnosis of degenerative dorsal disc herniation are included. All patient were subjected to (1) full clinical examination (2) study of some haemorheological parameters and vascular risk factors (3) plain x ray dorsal spine (4) Myelography with postmyelography CT scan of the dorsal spine (5) MRI examination of t...

We reviewed 104 consecutive cases of closed dysraphism in patients seen at one institution between December 1984 and June 1987. All patients had myelographic studies, and 43 had associated CT examinations. Clinical and surgical findings (64 patients) were correlated with myelographic information. Twenty-three patients (22%) with clinical or plain film findings compatible with dysraphism had nor...

A parallel, double-blind, randomized study comparing iohexol and metrizamide-both 180 mg I/ml-in lumbar myelography was carried out in 60 consecutive patients. Eight to 15 ml of contrast medium were administered with the upper level at the middle thoracic column. A detailed neurologic examination was performed before and 24 hr after myelography. EEG recordings-evaluated visually and with fast F...

BACKGROUND AND PURPOSE The purpose of this work was to provide an intraindividual comparison of angiographic CT (ACT) and multisection CT (MSCT) in lumbar myelographic imaging and to evaluate possible benefits of ACT, which is a further development of rotational angiography providing image data of high spatial and CT-like contrast resolution. MATERIALS AND METHODS In 26 patients with degenera...

To date, there have been no prospective, objective studies comparing the accuracy of the MRI, myelo-CT and myelography. The purpose of this study is to compare the diagnostic and predictive values of MRIs, myelo-CTs, and myelographies. Myelographies with dynamic motion views, myelo-CTs, MRIs and exercise treadmill tests were performed in 35 cases. The narrowest AP diameter of the dural sac was ...

Aim To investigate the feasibility and effectiveness of intraoperative myelography in determining adequacy of indirect spinal canal decompression during transpsoas lateral lumbar interbody fusion (LLIF). Methods Seven patients diagnosed with degenerative lumbar spinal stenosis (DLSS) were prospectively included to this study. All patients underwent LLIF and subsequently received intraoperativ...

Deformities of the margins of the contrast material-filled lumbar thecal sac are common findings at myelography in patients with low back pain, but not all such deformities are due to herniated disks. Differentiation at Amipaque myelography between a diffusely bulging disk (unlikely to cause nerve root compression) and a herniated disk (which typically causes nerve root compression) is based on...

We would like to propose floating dural sac sign, which is observed as a hyperintense band or rim around the spinal dural sac on axial T2-weighted images, as a sensitive sign to identify cerebrospinal fluid (CSF) leakage. One hundred patients with orthostatic headache were prospectively registered in 11 hospitals. These patients were examined by brain magnetic resonance (MR) imaging (n = 89), r...

Recognized risk factors for metrizamide myelography are seizure disorder, seizure-threshold-lowering drugs, dehydration, and possibly age. After observing serious neurologic complications in diabetic patients after routine metrizamide myelography, a retrospective study was conducted to determine if diabetes should be considered another independent and important risk factor. Forty-one diabetic p...
