Attenuation values of the cerebrospinal fluid (CSF)
Neuroradiology
|May 31, 1978
Summary
Computed tomography (CT) attenuation values of cerebrospinal fluid (CSF) were measured. Protein content did not correlate with CSF CT attenuation, suggesting its use for artifact detection.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Cerebrospinal fluid (CSF) analysis is crucial in neurological diagnostics.
- Computed tomography (CT) is a common neuroimaging technique.
- Understanding factors influencing CT attenuation values of CSF is important for accurate interpretation.
Purpose of the Study:
- To determine the relationship between cerebrospinal fluid (CSF) protein content and its attenuation value measured by computed tomography (CT).
- To assess the potential of CSF CT attenuation values for detecting artifacts.
Main Methods:
- CSF samples were obtained from 25 patients via lumbar puncture.
- Attenuation values of CSF were measured using computed tomography.
- Protein content in the CSF samples was analyzed.
Main Results:
- No significant correlation was found between CSF protein concentration and its CT attenuation value.
- The effect of protein concentration on CSF attenuation is negligible within the normal range.
Conclusions:
- CSF CT attenuation values are not significantly influenced by protein content in the normal range.
- CSF CT attenuation measurements may serve as a reliable method for identifying substantial deviations in CT numbers caused by artifacts.
