MRI is an excellent means of visualization of a narrowed spinal canal associated with spinal cord compression due to degeneratively changed spine. New modalities such as multiarray coils provide high-resolution sagittal images of the entire cord in a single scan and fast spin-echo sequences produce high-resolution T2-weighted imaging (T2WI) within a short time [40].

Cord compression due to metastatic disease is most common in the thoracic region and may require acute surgical decompression or radiotherapy. MRI is the investigation of choice for suspected spinal cord compression (Fig. 9.19).

All the patients who were diagnosed with KD were admitted between May 2010 and August 2015. A total of 19 patients (males, n = 7; females, n = 12) were enrolled in this study. They were aged from 65 to 87 years, with a mean age of 73.45 ± 5.62 years. Thirteen of the patients had a definite history of trauma (falling history, n = 9; sprain history, n = 4). The period of lumbago pain was 4 weeks to 6 months, with an average of 2.3 months. Low back pain self-mitigation occurred in 8 cases of trauma, which was the performance of KD’s typical occult, and occult duration lasted 4 weeks to 3 months (average of 5.8 weeks). In cases of recurrence of low back pain symptoms or an increase in these symptoms, patients were hospitalized. The remaining 19 cases initially had low back pain, which gradually developed into serious low back pain, with postural changes and pain in various postures (e.g. standing from a sitting position, sitting, and standing still). Conservative treatment was considered inappropriate in these cases. Among these cases, the spinal cord compression symptoms in 3 patients were manifested as decreased lower limb muscle strength and sensory disturbance. The involved vertebrae in 20 vertebrae (19 patients) were as follows: T10 vertebra (n = 1), T11 vertebra (n = 3), T12 vertebra (n = 8), L1 vertebra (n = 6), L2 vertebra (n = 1), and L2 combined with spinous process fracture (n = 1). The bone mineral density (T) was −2.8 to −6.0, with an average of −3.68.
