Description

In this detailed presentation, the speaker elaborates on MRI and CT imaging techniques used for diagnosing spinal issues, particularly focusing on degenerative spinal disc diseases. The advantages of CT imaging include excellent volumetric assessment of bone structures and the capability for various reconstructions like MPR, MIP, and 3D volume rendering. MRI, on the other hand, offers high contrast resolution and is particularly effective for evaluating intervertebral discs, ligaments, and bone lesions. The speaker discusses different types of spinal issues, such as disc cracking, fluid collections in discs, and osteophytes. They also explain different types of degenerative changes classified as Modic changes and various forms of herniated discs, including under ligamentous, expelled, and sequestered hernias. The use of contrast medium in distinguishing between herniated discs and neurinoma is also addressed. The presentation concludes with a comparison between a normal spinal canal and one with stenosis, highlighting the impact of lumbar spondylarthrosis and facet joint arthrosis on spinal canal diameter.
