Total myelography with metrizamide through the lumbar route

Area of Science:

• Radiology
• Neurology
• Medical Imaging

Background:

• Metrizamide myelography is a diagnostic tool for spinal cord imaging.
• Optimizing the technique for whole-body imaging is crucial for diagnostic accuracy.

Purpose of the Study:

• To evaluate the efficacy and safety of whole-body spinal cord myelography using metrizamide.
• To identify technical factors contributing to successful imaging.

Main Methods:

• Whole-body myelography was performed on 64 patients using lumbar puncture with metrizamide.
• Technical factors including patient cooperation, contrast concentration, injection rate, and procedure speed were controlled.

Main Results:

• Successful opacification of the cervical and thoracic subarachnoid space was achieved in 63 out of 64 patients (98.4%).
• Minor side effects were observed, comparable to lumbar myelography alone.
• Adequate hydration and post-procedure upright positioning were associated with reduced adverse effects.

Conclusions:

• Whole-body metrizamide myelography is a highly successful imaging technique for the entire spinal cord.
• Specific technical factors are critical for achieving optimal opacification and patient safety.
• Metrizamide myelography remains a valuable tool for spinal cord evaluation.
