Learning Objectives: 1. Describe the role that both CT and SPECT imaging play in the diagnosis, staging and follow-up of neuroendocrine tumors. 2. Present the limitations of each modality when applied separately to evaluate these tumors. 3. Discuss the improved accuracy, diagnostic value and clinical utility of using SPECT/CT fusion compared to either study separately.

Abstract Body: Neuroendocrine tumors are usually small in size and lack anatomic delineation which makes their detection on conventional imaging difficult. Although the advent of SPECT In-111 pentetreotide imaging has greatly improved the diagnosis, staging and follow-up of these lesions, this imaging modality alone lacks the accurate anatomic localization necessary for optimal patient management and surgical planning. Since SPECT/CT overcomes this critical limitation, it has proved to be more accurate than SPECT and CT alone and results in the most appropriate patient management. In an effort to reveal the diagnostic value and clinical utility of SPECT/CT fusion, we review cases of pathology proven primary neuroendocrine tumors detected by this powerful imaging tool.
