Background: Isocentric C-arm fluoroscopic cone beam CT (CBCT) is a new technique for near real time 3-D volume imaging guidance of percutaneous interventional procedures. In combination with digital flat panel detectors, CBCT has high spatial resolution with isotropic voxel size, allowing for high resolution image reconstruction in any plane, including 3D rotational reconstructions. CBCT combines the advantages of conventional CT imaging guidance with the improved spatial resolution, patient positioning, and access of fluoroscopy. Objective: The aim of this study is to demonstrate the advantages of CBCT over conventional CT and biplane fluoroscopy for imaging guidance of minimally invasive spinal and paraspinal interventional procedures. Methods: Five patients referred to the department of interventional neuroradiology for percutaneous spinal or paraspinal interventional procedures were intraoperatively evaluated with CBCT to assist in guidance of instrumentation placement. Procedures included transoral cervical vertebral biopsy, percutaneous thoracic vertebral biopsy, vertebroplasty, pelvic paraspinal/epidural abscess drainage, and paraspinal fiducial marker placement for treatment of osteoid osteoma. Results: All procedures were successfully performed with satisfactory diagnostic yield or therapeutic effect without procedure-related complications. Conclusion: Isocentric C-arm fluoroscopic cone beam CT (CBCT) is a new technique for 3D volume imaging guidance of interventional procedures of the spine with the capability to produce near real time high resolution image reconstructions in any plane. Compared to conventional CT and biplane fluoroscopy, CBCT offers improved anatomic visualization allowing high accuracy instrumentation placement, improving procedure results and minimizing risk of complications.

Background and purpose A frequently reported drawback of ethylene vinyl alcohol copolymer-based liquid embolic agents is the production of artifacts in diagnostic imaging. New embolic agents, such as Precipitating hydrophobic injectable liquid (PHIL; MicroVention, Tustin, CA, USA), are supposed to induce significantly fewer artifacts. The purpose of this study is to assess the degree of artifacts induced by the liquid embolic agents Onyx (Medtronic Neurovascular, Irvine, CA, USA) and PHIL in conventional computed tomography (CT), cone-beam CT and magnetic resonance imaging (MRI) in an experimental in vivo model. Materials and methods In 10 pigs the rete mirabile was embolized with Onyx ( n = 5) or PHIL ( n = 5). After embolization, conventional CT, cone-beam CT and MRI were performed. The degree of artifacts was graded qualitatively (five-point scale; for CT and MRI) and quantitatively (HUs of well-defined regions of interest (ROIs); for CT only). Results Artifacts were significantly more severe for Onyx both in the qualitative (e.g. conventional CT: 2 versus 5 (medians); p = 0.008) and in the quantitative image analysis (e.g. cone-beam CT: standard deviation of a ROI near to the embolic agent cast, 94 HU versus 38 HU (medians); p = 0.008). Neither Onyx nor PHIL produced any apparent artifacts in MRI. Conclusion PHIL produces fewer artifacts than Onyx in conventional CT and cone-beam CT in an experimental in vivo model.
