    Theory and practice: how much contrast for myelography? (1991)
    Springer
    Neuroradiology 33 (1991), S. 411-413 
    Details
    ISSN: 1432-1920
    Keywords: Myelography ; Contrast medium ; Dose limitation

    Notes: Summary A questionnaire sent to members of the British Society of Neuroradiologists revealed that the majority of practitioners will, when necessary, inject more than 3 g of iodine during myelography with iohexol or iopamidol. The 3 g limit recommended by the contrast medium manufacturers is not based upon scientific studies involving these media, and it is the experience of British neuroradiologists that larger amounts of modern contrast agents can be used without an increase in post myelography complications. There is, therefore, a need for a controlled trial to assess the question of the most appropriate dose of contrast medium in myelography.

    MRI of idiopathic orbital inflammatory syndrome using fat saturation and Gd-DTPA (1995)
    Springer
    Neuroradiology 37 (1995), S. 475-478

    Notes: Abstract Idiopathic orbital inflammatory syndrome encompasses a group of inflammatory conditions for which no systemic or local cause can be found, and is commonly referred to as orbital pseudotumour. On conventional MRI sequences subtle areas of inflammation or enhancing tissue can easily be masked by the high signal intensity of orbital fat and involvement of the fat itself may not be appreciated. We describe the MRI features of three patients with idiopathic orbital inflammation using frequency-selective fat saturation and Gd-DTPA.

    Uncommon posterior cranial fossa anomalies: MRI with clinical correlation (1995)

    Notes: Abstract The clinical and MRI findings in two cases of rhombencephalosynapsis (RS) and two of tectocerebellar dysraphia (TCD) with an associated occipital encephalocele were studied to elucidate the clinical picture and embryogenesis of these rare anomalies. To our knowledge, only one case of TCD [1] and four of RS [2, 3] examined by MRI during life have been reported. The clinical picture in the cases of RS was rather constant and there were similarities with TCD. Consideration of the embryogenesis of the neural tube suggests a temporal proximity of the abnormalities, with TCD arising at a slightly earlier time.

    MRI of the anterior optic pathways following enucleation (1997)
    Springer
    Neuroradiology 39 (1997), S. 815-817

    ISSN: 1432-1920
    Keywords: Key words Enucleation ; Optic nerve ; Magnetic resonance imaging

    Topics: Medicine
    Notes: Abstract We examined five patients who had enucleation of one eye for inflammatory or neoplastic disease, using MRI at 1.5 Tesla. None had symptoms referable to the enucleated orbit. In addition, age- and-sex matched individuals were imaged as control subjects, and a further 15 subjects, referred for other than orbital disease, were reviewed. Measurements were made retrospectively of the dimensions of the optic chiasm to establish normal values. All five patients showed abnormalities on MRI following enucleation: abnormal signal within the optic nerve remnant on short τ inversion recovery (STIR) images, and atrophy of the nerve remnant and the chiasm. These findings were not apparent in the control or normal subjects. Such findings are to be expected following enucleation and should not be interpreted as indicating active pathology.

    Diagnosing CADASIL using MRI: evidence from families with known mutations of Notch 3 gene (2000)

    Topics: Medicine
    Notes: Abstract Clinical data and MRI findings are presented on 18 subjects from two families with neuropathologically confirmed CADASIL. DNA analysis revealed mutations in exon 4 of Notch 3 gene in both families. All family members with mutations in Notch 3 gene had extensive abnormalities on MRI, principally lesions in the white matter of the frontal lobes and in the external capsules. Of several family members in whom a diagnosis of CADASIL was suspected on the basis of minor symptoms, one had MRI changes consistent with CADASIL; none of these cases carried a mutation in the Notch 3 gene. MRI and clinical features that may alert the radiologist to the diagnosis of CADASIL are reviewed. However, a wide differential diagnosis exists for the MRI appearances of CADASIL, including multiple sclerosis and small-vessel disease secondary to hypertension. The definitive diagnosis cannot be made on MRI alone and requires additional evidence, where available, from a positive family history and by screening DNA for mutations of Notch 3 gene.

    A prospective comparison of brain contrast characteristics and lesion detection using single-shot fast spin-echo and fast spin-echo (1999)

    Notes: Abstract MRI is limited by movement artefact, even with current imagers, when examining a restless or claustrophobic patient. We prospectively analysed the images of 92 patients produced by a single-shot fast spin-echo (SSFSE) pulse sequence and compared them with conventional (FSE) and reduced-time fast spin-echo (RT-FSE) techniques, with regard to lesion detection and movement artefact in brain imaging. Images obtained in each case were independently reviewed and scored for overall diagnosis, number of lesions detected, and movement artefact. FSE showed 1217 lesions, RT-FSE 1137, and SSFSE 1044. This discrepancy arose mainly in patients with multiple sclerosis or small-vessel disease, since with SSFSE we were less able to separate small, adjacent low-contrast lesions than with FSE. Arbitrary movement scores were 36, 25 and zero respectively. There were, however, no clinically significant differences in overall diagnosis between the three techniques. SSFSE thus proved a reliable, fast, accurate method for obtaining T2-weighted images, and may be of particular use in the restless, claustrophobic or obtunded patient.

    Notes: Summary Approximately 1% of meningiomas arise in extradural sites. Intradiploic meningiomas form only a very small proportion of this number. They tend to occur in young patients. The CT and MRI apperances, although unusual, may be characteristic of the condition. We present two cases and describe the CT and MR appearance; the latter has not previously been described.
