A review of the value of MRI signs in low back pain

Area of Science:

• Radiology
• Orthopedics
• Pain Management

Background:

• Low back pain is a prevalent condition causing significant disability and socio-professional impact.
• Despite advanced imaging techniques like MRI, the precise etiology of low back pain frequently remains undetermined.
• Age-related degenerative changes in the spine are often observed on MRI, irrespective of symptomatic presentation.

Purpose of the Study:

• To review the current understanding of low back pain etiology in relation to imaging findings.
• To highlight key features for radiological practice concerning spinal aging and pain.
• To discuss the diagnostic value of imaging signs in low back pain.

Main Methods:

• Comprehensive literature review of anatomical, physiopathological, and semiological findings of the spine.
• Focus on anterior and posterior spinal segments.
• Analysis of the diagnostic utility of various imaging signs.

Main Results:

• Normal aging of intervertebral discs can manifest as morphological changes on MRI.
• The interpretation of these imaging findings in the context of low back pain requires careful consideration.
• Specific anatomical and physiopathological signs hold diagnostic value.

Conclusions:

• Radiological assessment, particularly MRI, plays a crucial role in evaluating low back pain.
• Distinguishing between age-related changes and pathology is essential for accurate diagnosis.
• This review provides a framework for interpreting imaging findings in routine practice.
