Compare image quality between the Optima and Intevo as primary objective and 2.Does one device produce images that are more impactful on clinical management as a secondary objective. In this study, the investigators hope to compare images using the standard and proprietary algorithms to determine if these provide equal or different levels of image interpretation confidence by the reader as well as changes in clinical management. The Bold, on the other hand, has a proprietary reconstruction algorithm called xSPECT which does use the CT data to extract a zone map to better delineate tissue boundaries. The Optima uses the Volumetrix Evolution algorithm to reconstruct SPECT data that does not incorporate the CT data into these reconstructions. The nuclear department has two cameras that are capable of performing SPECT-CT, an Optima manufactured by GE and a Symbia Intevo Bold manufactured by Siemens. This information can help guide therapy to the most active sites of disease which MRI and CT cannot do as anatomic imaging modalities. It can supplement other types of imaging like MRI by providing physiologic information about the type and location of various disease processes. SPECT-CT is evolving into an integral part of patient management in those having back pain.
