Abstract:
In a comparative study between Dimer X and Amipaque (metrizamide) for lumbar myelography it was found that there is a little higher frequency of monor, but unimportant side effects after Amipaque. Amipaque has also been used for thoracocervical myelography with excellent results and without greater discomfort than after myelography in the lumbar region. A new puncture technique was used for the eximation of the cervical region alone: lateral puncture on the neck between the laminae of C1 and C2 under TV control. In more than 75 reinvestigations no arachnoid changes were observed.
Insights
Amipaque (metrizamide) is a safe and effective contrast agent for lumbar and thoracocervical myelography, showing minimal side effects compared to Dimer X. A novel C1-C2 lateral puncture technique proved safe for cervical imaging.
Area of Science:
- Radiology
- Neuroradiology
- Diagnostic Imaging
Background:
- Lumbar myelography is a common diagnostic procedure.
- Dimer X and Amipaque (metrizamide) are contrast agents used in myelography.
- Evaluating the safety and efficacy of contrast agents is crucial for patient outcomes.
Purpose of the Study:
- To compare the efficacy and side effect profiles of Dimer X and Amipaque (metrizamide) for lumbar myelography.
- To assess the utility and patient comfort of Amipaque for thoracocervical myelography.
- To evaluate a new lateral puncture technique for cervical myelography.
Main Methods:
- Comparative study of Dimer X and Amipaque (metrizamide) in lumbar myelography.
- Application of Amipaque for thoracocervical myelography.
- Introduction and evaluation of a lateral C1-C2 puncture technique under fluoroscopic guidance for cervical imaging.
Main Results:
- Amipaque demonstrated a slightly higher frequency of minor, non-significant side effects compared to Dimer X in lumbar myelography.
- Amipaque yielded excellent results for thoracocervical myelography with comparable discomfort to lumbar procedures.
- The novel lateral C1-C2 puncture technique was successfully employed in over 75 examinations without observed arachnoid changes.
Conclusions:
- Amipaque is a suitable and well-tolerated contrast agent for both lumbar and thoracocervical myelography.
- The new lateral puncture technique offers a safe and effective approach for cervical myelography.
- These findings support the expanded use of Amipaque and the novel puncture technique in neuroradiological imaging.
