Summary

This prospective comparative observational study evaluates image quality characteristics and short-term physiological effects associated with contrast-enhanced magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in patients with cervical and lumbar spinal pathologies.

A total of 120 adult participants undergo either contrast-enhanced MRI or FDG-PET/CT as part of routine clinical evaluation. Image quality is assessed using quantitative metrics, including signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR), as well as qualitative Visual Grading Analysis (VGA) performed by blinded radiologists. Short-term physiological effects are evaluated using blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), and hemoglobin measurements obtained before imaging and 48 hours after imaging.

The study aims to compare image quality characteristics and short-term physiological parameters associated with these imaging modalities and to examine the influence of age group and spinal region on imaging performance.
