For diagnosing arachnoiditis Contrast enhanced study is definitely indicated to look adherent enhancing nerve roots. Arachnoiditis is a broad term denoting inflammation of the meninges and subarachnoid space. A variety of etiologies exist, including infectious, inflammatory, and neoplastic processes. Infectious etiologies include bacterial, viral, fungal, and parasitic agents. Noninfectious inflammatory processes include surgery, intrathecal hemorrhage, and the administration of intrathecal agents such as myelographic contrast media, anesthetics, and steroids.
Thank you for your response. I will ask my doctor for a referral for MRI with contrast.
Thanks again,
