Canine degenerative lumbosacral stenosis (DLSS) is a syndrome of low back pain with or without neurologic dysfunction associated with compression of the cauda equina. Most commonly occurring in medium- to large-breed dogs of middle to older age, German shepherd and working dogs are predisposed.

2016年11月27日 · (B) Midsagittal plane MRI demonstrates intervertebral disc degeneration at the lumbosacral junction associated with central protrusion and ventral spondylosis. (C and D) Transverse and parasagittal plane MR images demonstrate marked ventral spondylosis and marked abaxial encroachment of the left L7 neuroforamen (right on image) by protruding ...

2005年7月1日 · MRI features in dogs with degenerative lumbosacral stenosis include degeneration of the nucleus pulposus as evidenced by a decreased signal intensity on a T2-weighted image, protrusion of the annulus fibrosis, narrowing of the vertebral canal, loss of epidural fat overlying the intervertebral disk herniation (Figure 11), compression of the L7 ...

The L7 vertebra is key in keeping us standing tall and doing everyday tasks. It also helps us play sports. Knowing how the L7 spine works helps us take care of our backs.

2021年4月7日 · Magnetic resonance imaging (MRI) was performed and identified compression of the cauda equina and L7 nerve root associated with intervertebral disc herniation (IVDH) at L6‐L7 as well as widespread sciatic nerve enlargement with moderate rim enhancement.

Diagnostic imaging findings agreed regarding affected site(s) in 99 of 165 cases (60.0%). Two dogs with equivocal radiographic findings had definitive evidence of disease on MRI. One dog had an L7‐S1 lesion suspected on radiographs that was not reported on MRI, and 1 dog had multifocal lesions detected on CT but not on MRI.

2021年1月21日 · We used magnetic resonance imaging (MRI) to image and analyze the spinal cords of rats, cats, domestic pigs, rhesus monkeys, and humans, and created atlases with a minimum resolution of 1 mm ×...

MRI interrogation of the LS spine in dogs has been used to divide the L7-S1 intervertebral foramen (IVF) into entrance, middle and exit zones, allowing description of a foramin as stenotic when loss of the fat signal is complete or when only a minimal rim of fat signal is visible within one of the foraminal zones on parasagittal imaging plane ...

2022年3月12日 · Eighty-seven percent of herniations occurred at L5-L6 or L6-L7. A good to excellent outcome was seen in 95% of surgically and 90% of medically treated dogs.

2025年2月11日 · Lumbosacral transitional vertebrae (LSTV) are a relatively common variant and can be seen in ~25% (range 15-35%) of the general population 1-3. Non-recognition of this variant and/or poor description in the report can lead …
