Background
Hybrid molecular imaging, including PET/CT, PET/MRI, and SPECT/CT, is evolving as a critical tool in the practice of individualized medicine. The application of hybrid molecular imaging is useful in numerous clinical situations in which the combination of molecular and structural imaging increases diagnostic accuracy, sensitivity, specificity, and clinical confidence. Optimizing protocols and ensuring radiologists are familiar with less common indications for hybrid imaging will continue our field’s progress toward improved patient care.

Educational Goals / Teaching Points
The goals of this exhibit are to illustrate the ability of hybrid molecular imaging to localize pathologic processes where anatomic imaging alone fails; display cases demonstrating the problem-solving capabilities of hybrid molecular imaging; identify clinically appropriate situations to apply hybrid molecular imaging; and discuss protocol optimization, specifically focused on anatomic imaging (CT and MRI).

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key points of this exhibit include SPECT/CT, PET/CT, PET/MRI, malignant peripheral nerve sheath tumor, parathyroid adenoma, and gastrointestinal bleed

Conclusion
Hybrid molecular imaging is an underutilized instrument in the radiologist’s imaging toolbox. Understanding the combination of anatomic and physiologic information provides the radiologist with vital information that can make a cryptic diagnosis possible. Knowing how and when to apply this powerful tool is key to guiding patient care.
