Technological advances in existing modalities such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) have furthered their utility as diagnostic and management instruments, while the indications for newer imaging modalities such as 2-(18F)-fluoro-2-deoxy-D glucose (FDG) positron emission tomography (PET)/CT continue to expand. The use of tumor markers in identifying disease and molecular pathology in confirming which specific disease exists is presented. Because of the important role played by these diagnostic tools, the gynecologic oncologist must possess at least a passing familiarity with the basic science underlying these diagnostic instruments, as well as understand their advantages and limitations in imaging the spectrum of gynecologic cancers. Not all diagnostic modalities are useful or appropriate in evaluating the different and varied gynecologic cancers. Furthermore, the impact of diagnostic studies in the field of gynecologic oncology is ever expanding as newer technological developments become available to the clinician who must understand how to translate these advancements into improved patient care. Finally, as cost-effectiveness becomes an ever more important driver of health care decision making, it behooves the gynecologic oncologist to understand the various diagnostic tools in his armamentarium in order to use them to maximal effect.
