Correlation is defined as a connection or relationship between two or more things that are not caused by chance. Medical research is naturally based on finding the relationship between the known and the unknown. Correlation has been an integral part of medicine. A clinician correlates signs and symptoms with the results of medical imaging, pathology or laboratory investigations. A nuclear medicine physician or radiologist correlates findings of medical imaging with another imaging modality or laboratory investigation such as tumor marker levels, hormone levels etc. Correlative imaging comprises combining complimentary information provided by different imaging techniques for better interpretation of pathology. In this chapter, our aim is to familiarize readers with the basics of correlative imaging, the strengths and shortcomings of various imaging modalities, and how the correlation among them leads to better understanding of pathologies. The main emphasis of this chapter will be on “fusion imaging”, which has proved to be the best available form of correlative imaging at present.
