[A clinical study on the diagnosis of spinal cord tumor using magnetic resonance imaging]
1Department of Orthopaedic Surgery, School of Medicine, Chiba University, Japan.
Abstract:
Thirty-five patients with a variety of spinal cord tumors were studied by magnetic resonance imaging (MRI). In 22 out of these cases, the efficacy of Dimeglumine gadopentetate (Gd-DTPA) in enhancing MRI was also investigated. The results were as follows: (1) MRI was capable of discerning the level of tumors. (2) MRI was able to distinguish intramedullary from extramedullary tumors. MRI, however, could not always differentiate extradural from intradural tumors. (3) Some cases of lipoma, arteriovenous malformation and hematoma were diagnosed by MRI. (4) Gd-DTPA was found to be effective in enhancing MRI in all cases of spinal cord tumors with exception of two cases of arteriovenous malformations. In conclusion, MRI is very useful in diagnosing spinal cord tumors. MRI, when enhanced with Gd-DTPA, is capable of revealing the content of tumors but also differentiating intramedullary tumors from surrounding edema and syrinx.
Insights
Magnetic resonance imaging (MRI) effectively diagnoses spinal cord tumors, identifying their level and type. Contrast enhancement with Dimeglumine gadopentetate (Gd-DTPA) further improves tumor visualization and differentiation.
Area of Science:
- Neurology
- Radiology
- Oncology
Context:
- Spinal cord tumors present diagnostic challenges.
- Accurate tumor characterization is crucial for treatment planning.
Purpose:
- To evaluate the diagnostic utility of magnetic resonance imaging (MRI) for spinal cord tumors.
- To assess the efficacy of Dimeglumine gadopentetate (Gd-DTPA) contrast enhancement in MRI.
Summary:
- MRI accurately determined tumor level and differentiated intramedullary from extramedullary lesions.
- MRI diagnosed various tumor types including lipoma, arteriovenous malformation, and hematoma.
- Gd-DTPA enhanced MRI in most cases, improving tumor content visualization and differentiation from edema/syrinx.
Impact:
- MRI is a valuable tool for diagnosing spinal cord tumors.
- Gd-DTPA enhanced MRI aids in detailed tumor characterization, guiding clinical management.
