Cervical Lordosis: Imaging Position and Measurement

Condition(s) studied

Investigational drug(s) / intervention(s)

No intervention: This is an observational study with no assigned intervention. Groups are defined based on the imaging modality (standing radiograph vs supine MRI).

Study summary

This retrospective cross-sectional study aims to compare cervical lordosis measurements obtained from standing lateral radiographs and supine magnetic resonance imaging (MRI) in individuals without structural cervical pathology. The study also evaluates the independent contribution of T1 slope to cervical alignment and investigates whether imaging modality significantly alters measured lordosis values.

Eligibility

Primary outcome measure(s)

• Difference in Cobb C2-C7 angle between standing radiographs and supine MRI — Baseline retrospective image assessment
  Cobb C2-C7 angle measured using standard endplate-based methodology on standing lateral cervical radiographs and supine cervical MRI. The primary comparison evaluates the difference in cervical lordosis between imaging modalities obtained under weight-bearing and non-weight-bearing conditions.
• Difference in Cobb C1-C7 angle between standing radiographs and supine MRI — Baseline retrospective image assessment
  Cobb C1-C7 angle measured on standing lateral radiographs and supine MRI using standard radiographic techniques. This outcome assesses global cervical lordosis differences between imaging modalities.
