Ventriculography with metrizamide
1Department of Diagnostic Radiology, University Hospital, Lund, Sweden.
Abstract:
In 77 patients 85 ventriculographies were performed with metrizamide (Amipaque). No severe complications occurred. The diagnostic accuracy in lesions affecting the midline structures is excellent. However, the rapid passage of the medium from the ventricular system in cases with slight obstructions or small lesions requires a scrupulous technique to enable an exact diagnosis. Due to the difficulty in differentiating between intra- and extra-cerebral location of an expansivity, encephalography should be performed as the first examination whenever possible.
Insights
Metrizamide ventriculography in 77 patients showed no severe complications and excellent accuracy for midline brain lesions. Careful technique is needed due to rapid contrast medium passage, suggesting encephalography as a preferred initial diagnostic step.
Area of Science:
- Neuroradiology
- Diagnostic Imaging
Background:
- Metrizamide (Amipaque) is a contrast agent used in neuroradiology.
- Ventriculography is an imaging technique to visualize the cerebral ventricles.
Purpose of the Study:
- To evaluate the safety and diagnostic accuracy of metrizamide ventriculography.
- To assess the utility of metrizamide ventriculography for diagnosing lesions affecting midline brain structures.
Main Methods:
- 85 metrizamide ventriculographies were performed in 77 patients.
- The study assessed complication rates and diagnostic accuracy.
Main Results:
- No severe complications were observed during the procedures.
- Diagnostic accuracy was excellent for midline brain structure lesions.
- Rapid contrast medium passage in cases of slight obstructions or small lesions necessitates meticulous technique.
Conclusions:
- Metrizamide ventriculography is a safe procedure with high diagnostic value for midline lesions.
- Scrupulous technique is crucial due to the rapid contrast flow.
- Encephalography may be preferable as an initial examination due to challenges in differentiating intra- and extra-cerebral expansivities.
