We present the case of a 64-year-old man with cervical ossification of the posterior longitudinal ligament (OPLL) experiencing chronic neck pain and radiculopathy for 6 months. A catheter-assisted interlaminar Cervical Epidural Steroid Injection (CESI) was performed under fluoroscopic guidance, targeting the affected C2-C6 levels. Significant improvement was observed after this procedure, with decreased pain scores (visual analogue scale (VAS) 8 to 2) and improved mobility. This technique not only enhances the effectiveness of CESI but also reduces the likelihood of complications such as stroke or epidural hematoma and thus provides an alternative treatment option for patients with multiple stenotic levels who are unsuitable for surgery or are unresponsive to conservative therapy such as medication or physical therapy.

PurposeTo propose a method for simultaneous fluorescence and Compton scattering computed tomography by using linearly polarized *** Carlo simulations were adopted to demonstrate the feasibility of the proposed method. In the simulations, the phantom is a polytetrafluoroethylene cylinder inside which are cylindrical columns containing aluminum, water, and gold (Au)-loaded water solutions with Au concentrations ranging between 0.5 and 4.0 wt%, and a parallel-hole collimator imaging geometry was adopted. The light source was modeled based on a Thomson scattering X-ray source. The phantom images for both imaging modalities were reconstructed using a maximumlikelihood expectation maximization *** the X-ray fluorescence computed tomography (XFCT) and Compton scattering computed tomography (CSCT) images of the phantom were accurately reconstructed. A similar attenuation contrast problem for the different cylindrical columns in the phantom can be resolved in the XFCT and CSCT images. The interplay between XFCT and CSCT was analyzed, and the contrast-to-noise ratio (CNR) of the reconstruction was improved by correcting for the mutual influence between the two imaging modalities. Compared with K-edge subtraction imaging, XFCT exhibits a CNR advantage for the *** XFCT and CSCT can be realized by using linearly polarized X-rays. The synergy between the two imaging modalities would have an important application in cancer radiation therapy
