Transient Ischemic Dilation with <sup>18</sup>F-flurpiridaz PET: Establishing Thresholds for a Novel Radiotracer
Listen to this summary
The authors aimed to establish normal thresholds for transient ischemic dilation (TID) using the novel radiotracer <sup>18</sup>F-flurpiridaz in patients with suspected coronary artery disease (CAD). Through a secondary analysis of the Flurpiridaz-301 trial, they determined stress-specific TID reference thresholds and found that these values varied by stress modality and were influenced by post-reconstruction filtering. The study underscores the need for tracer- and protocol-specific standards for accurate clinical interpretation of TID in nuclear cardiology.
