Veterinary Services Postsurgical magnetic resonance imaging (MRI) is seldom performed for fear of poor image quality; however, MRI studies evaluating implant related artifacts in the canine vertebral column are lacking. Six canine cadaveric cervical vertebral columns were instrumented with monocortical titanium (Ti) screws and six with stainless steel (SS) screws. The imaging protocol consisted of the following sequences: T1-weighted, T2-weighted, STIR and SPIR. A scoring system (0-1-2-3) was used to rank evaluator ability to assess a total of 20 different regions of interest across four contiguous vertebrae (C3-C6). Ti monocortical screw/PMMA constructs produced significantly less susceptibility artifacting compared to SS constructs. Postoperative imaging with the intent to evaluate the spinal cord should not be avoided in patients with Ti screw constructs, but may cause mild artifacting associated with the osseous structures at the implanted site. Conversely, SS screw constructs will cause more severe susceptibility artifacts hindering interpretation of the implanted site; however, evaluation of anatomic structures outside the implanted site may be possible. Additionally, variations in implant positioning and angle may cause alterations in the location and degree of susceptibility artifacting. 2014-09-18 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1397716311 http://rave.ohiolink.edu/etdc/view?acc_num=osu1397716311 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
