Biophilia Intruder High Resolution Intervertebral Disc Degeneration

Due to the high resolution of NLS devices such as Biophilia Intruder, this method can not only reveal morphological damage, but also provide information on the extent of changes in degenerated discs. Degeneration of the intervertebral disc leads to dehydration of its tissue, which leads to progressive shrinkage of the intervertebral disc space and increased coloration of the image signal. The latter was associated with changes in the proteoglycan structure of the intervertebral disc; but it was not caused by absolute changes in water content. Loss of water from the intervertebral disc causes its height to decrease and the boundary between the nucleus pulposus and annulus fibrosus to disappear. As the degree of degeneration increases, fine fluid-filled fissures appear; they are detected as linear areas of high chroma. Calcification may develop later in the degenerated disc.

We can pick out (non-prominent local topics):

1) Disc herniation - a displaced intervertebral disc (nucleus pulposus) that stretches the annulus fibrosus with microfissures on the outside but no perforation;

2) Intervertebral disc herniation - part of the intervertebral disc breaks through the fibrous ring and protrudes to the epidural space;

3) Disc sequestrum - nucleus pulposus material moves above or below the disc.

The typical changes in the NLS diagram of bone marrow tissue near the intervertebral disc of vertebral degeneration can be divided into three types for convenience: vascular type, fatty type and sclerotic type.

Due to this fact, in most cases a sufficient study includes the following examinations: 2D scanning of the damaged intervertebral disc in sagittal and axial projections at the level of changes detected. The application of a three-dimensional scanning method is a practical way to emphasize the closure of the plate to detect its erosion and condition the bone marrow tissue.

The application of NLS microscanning is of great significance in assessing the degree of deformation and contraction of the dural sac, and the condition of the dural funnel to detect its deformation and misalignment.

Considering non-invasive and ionizing radiation-free, Biophilia Intruder technology can be used to dynamically monitor postoperative changes. To distinguish recurrent disc herniation from postoperative scarring, we used spectral entropy analysis. Mature scar tissue has its own special specter that is different from disc tissue, which is perfectly visible on SEA.
