Imaging of Discogenic and Vertebrogenic Pain

Area of Science:

• Orthopedics
• Radiology
• Pain Medicine

Background:

• Chronic low back pain is a global health issue with multifactorial causes.
• Discogenic pain, from intervertebral disc issues, and vertebrogenic pain, from vertebral endplates, are key anterior column pain generators.
• These pain types are often interconnected and linked to disc degeneration.

Purpose of the Study:

• To review the pathophysiology of vertebrogenic and discogenic pain.
• To explore the diagnostic capabilities of various imaging modalities for low back pain.
• To highlight advanced MRI techniques for detecting painful endplate and disc pathology.

Main Methods:

• Review of existing literature on low back pain pathophysiology and imaging.
• Comparison of traditional diagnostic methods (radiographs, discography) with advanced techniques (SPECT, CT, MRI).
• Focus on morphologic MRI, ultra-short-echo time imaging, and quantitative MRI for identifying Modic endplate changes, disc degeneration, and annular fissures.

Main Results:

• Morphologic MRI effectively reveals indicators of both vertebrogenic and discogenic pain.
• Advanced MRI methods significantly enhance the accuracy in detecting painful endplate and disc pathology.
• Imaging plays a crucial role in isolating pain generators and excluding comorbid conditions.

Conclusions:

• Vertebrogenic and discogenic pain are significant contributors to chronic low back pain.
• Advanced imaging, particularly MRI, is essential for accurate diagnosis.
• Improved diagnosis facilitates personalized treatment and image-guided therapies for low back pain patients.
