CME OnDemand: Novel Imaging and MIS Techniques in Foot and Ankle Care (2026)-Module 3

Video Transcription

Video Summary

Orthopedic foot and ankle surgeon Jensen Henry explains SPECT (single photon emission computed tomography), sometimes called SPECT-CT, which fuses nuclear “bone turnover” imaging (Tc99m-MDP tracer) with CT anatomy to create a 3D “heat map” of biologically active pathology. He reviews the three-phase bone scan technique and typical outputs (nuclear images, CT, and fused images). Indications include chronic pain with unclear radiographs, precise localization of symptomatic joints (e.g., midfoot arthritis) for injections or surgery, stress fractures, coalitions, and painful postoperative states (nonunion, painful ankle replacement). Evidence suggests improved specificity and impactful surgical planning. Pitfalls include radiation and the need to correlate with clinical findings and radiologist input.
