Abstract:
In 14 cases of unspecific infectious spondylodiscitis 11 patients underwent MR tomography, 3 of them were followed up. At the acute stage of the disease characteristic MR patterns are revealed. The main symptoms are 1) transdiscal hypointensity of the affected segment in T1-weighted images without differentiation of disk and adjacent vertebral bodies as well as 2) the manifestation of a hyperintense signal of diseased disks, vertebral bodies and paravertebral inflammation on T2-weighted images. A signal void is produced by sclerotic reactions of spongiosa. The formation of intraspinal abscesses and the compression of the spinal cord are clearly outlined by MR. When therapy is successfully applied, signal alterations largely normalize.
Insights
Magnetic resonance (MR) tomography reveals characteristic patterns in infectious spondylodiscitis. Successful treatment leads to normalization of MR signal alterations, aiding in disease monitoring.
Area of Science:
- Radiology
- Infectious Diseases
- Spinal Imaging
Context:
- Unspecific infectious spondylodiscitis presents diagnostic challenges.
- Early detection is crucial for effective management.
- Magnetic resonance (MR) tomography offers detailed spinal visualization.
Purpose:
- To identify characteristic MR imaging patterns of infectious spondylodiscitis in the acute stage.
- To evaluate the utility of MR tomography in diagnosing and monitoring the disease.
- To correlate MR findings with therapeutic outcomes.
Summary:
- MR tomography in infectious spondylodiscitis shows distinct T1- and T2-weighted image patterns.
- Key findings include transdiscal hypointensity (T1) and hyperintense signals in affected discs, vertebrae, and paravertebral tissues (T2).
- MR clearly delineates complications like intraspinal abscesses and spinal cord compression, with signal normalization indicating successful therapy.
Impact:
- Provides a comprehensive understanding of MR imaging in infectious spondylodiscitis.
- Enhances diagnostic accuracy and facilitates timely treatment.
- Demonstrates the role of MR in assessing therapeutic response and disease prognosis.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
