It requires exact injection of distinction materials into the spinal canal, sometimes within the lumbar area. Correct interpretation of the ensuing photographs is important for diagnosing varied spinal situations, resembling disc herniations, spinal stenosis, tumors, and infections. This process necessitates a radical understanding of spinal anatomy, potential problems, and radiation security protocols.
Proficiency on this method is crucial for affected person security and diagnostic accuracy. Improper needle placement or incorrect distinction administration can result in severe problems, together with nerve injury, bleeding, or an infection. Moreover, the power to discern refined abnormalities on myelographic photographs straight impacts the effectiveness of subsequent therapy selections. The event and growing use of much less invasive imaging modalities like MRI have lowered the reliance on myelography, but it surely retains its worth in particular scientific conditions, significantly for sufferers with contraindications to MRI, resembling these with sure implanted medical gadgets.
