Cerebrospinal fluid rhinorrhea: evaluation with metrizamide cisternography.
Metrizamide computed tomographic cisternography was used to examine 27 patients (19 males and eight females, 14-59 years old) clinically suspected of having cerebrospinal fluid fistulae with rhinorrhea. Twenty-one fistulae were traumatic and six were spontaneous. Five to 6 ml of metrizamide (or lopamidol, two cases) were injected by lumbar puncture at a concentration of 185-200 mg I/ml for dire...
متن کاملThe value of metrizamide CT cisternography in the management of cerebral arachnoid cysts.
Arachnoid cysts may or may not communicate with the cerebrospinal fluid pathways. Patterns of communication were studied in six patients, using metrizamide computed tomography (CT) cisternography, ventriculography, and cystography. Two types of cysts were found: one with free communication with the cerebrospinal fluid pathways and one with restricted communication. This information can be usefu...
متن کاملMetrizamide sagittal tomography: adjunct to CT cisternography of the sellar region.
A total of 30 patients with pituitary adenoma was studied by sagittal polytomography en route to coronal and axial computed tomography (CT) cisternography after a low FDA-approved dose of 6 ml of 170 mg I/ml metrizamide via lumbar injection. The requirement for defining the relation of the optic nerves and chiasm to the intrasellar contents or suprasellar mass before proton beam irradiation or ...
متن کاملLateral C2--C3 subarachnoid puncture for metrizamide myelography or cisternography.
Metrizamide is useful for evaluating both posterior fossa and the cervical spinal canal [1, 2]. Because the contrast material is diluted by spinal fluid enroute from the lumbar region to the cervical spinal canal, the C1-C2 puncture technique has been advocated as the most suitable approach for instillation of contrast material [3]. The procedure is safe and without great technical difficulties...
متن کامل¹¹¹In-DTPA cisternography with SPECT/CT for the evaluation of normal pressure hydrocephalus.
Although new MR imaging techniques can provide high-resolution information on CSF dynamics and are not associated with ionizing radiation, SPECT/CT cisternography is a valuable alternative for those with contraindications to MR imaging. SPECT/CT cisternography combines functional and anatomic imaging to provide accurate and detailed information on CSF distribution to be used in conjunction with...
