About the Course

Orthopedic implants are a routine part of modern clinical practice—and they often present radiologists and nuclear medicine physicians with challenging diagnostic questions. Knee and hip replacements, along with spinal fusion hardware, are among the most common procedures that require imaging follow-up—whether to clarify pain, suspected loosening, or infection.

In our new course, we demonstrate how hybrid imaging with SPECT-CT can significantly improve diagnostic accuracy by combining anatomical and functional information. The cases are thoroughly described, and many of them include video reviews that guide you through the interpretation process. Through practical examples and detailed case analysis, you’ll learn how to make the most of SPECT-CT in everyday clinical work.
