Technical feasibility vs. clinical utility: a question of “can we?” vs. “should we?”

Excerpt

In the current issue Lin et al. present the results of their study investigating the technical feasibility of a “cocktail” PET imaging approach whereby ¹⁸F-FDG and NaF were injected simultaneously (85%) or sequentially on the same day (15%). Compared with the FDG studies performed independently, the authors report improved sensitivity for detection of osseous metastatic lesions, nearly comparable soft tissue lesion detection, more efficient patient throughput, and reduced radiation exposure from the CT component of the simultaneous examination. The authors conclude that “cocktail” PET imaging is technically feasible; that is, it can be done using existing equipment [1]. …
