MRI Evaluation of Spinal Cord Edema After CT-Guided Percutaneous Cordotomy in Cancer Pain Patients

This observational study aims to evaluate changes in the spinal cord following CT-guided percutaneous cervical cordotomy performed for the treatment of intractable cancer-related pain. Cordotomy is a routine clinical procedure used to relieve severe pain in selected cancer patients. After the procedure, some patients may develop temporary neurological symptoms that are thought to be related to spinal cord edema. In this study, magnetic resonance imaging (MRI) will be performed as part of routine clinical follow-up on postoperative day 1 and at 1 month to assess the presence and extent of spinal cord edema. Clinical outcomes, including pain intensity and possible postprocedural symptoms, will be recorded and compared with MRI findings. The goal of this research is to better understand the relationship between imaging changes in the spinal cord and clinical outcomes after cordotomy, which may help improve patient care and postoperative management in the future.
