First ImageGuide Registry Publication Delivers Insights on Appropriateness, Utilization, More

The vast majority of the myocardial perfusion imaging cases submitted to the ImageGuide Registry® from 2015 through 2018 were appropriate (96%), of good or excellent quality (89%), and employed rest/stress 1-day protocol (88%). These were among a variety of findings published last week in the Journal of Nuclear Cardiology.
The publication delivers a real-world look at the landscape of nuclear cardiology in the U.S. today while also demonstrating the value of the ImageGuide Registry to help “answer important clinical questions,” says Peter L. Tilkemeier, MD, MMM, MASNC, study coauthor and chair of the joint ASE/ASNC Registry Oversight Committee.

The observational study focused on the 10,000 patient records submitted to the registry in its startup period, during which the steering committee intentionally limited participation to smaller practices so as to avoid overwhelming the data pool with the cases of large and hospital-based practices. The goal, the authors wrote, was to ensure that the early data were “representative of the greater community.”

Other key findings include – 

  • Chest pain was the most common primary indication.
  • The average patient was a 66-year-old man.
  • Technetium-99m was the most commonly used radiopharmaceutical..
  • SPECT cases outnumbered PET 4:1. 
  • Only 6.5% of cases used stress-only or stress-first protocols
This small study is a huge first step for ImageGuide's goal of providing the field with real-world data that will uncover opportunities for growth and improvement. Rami Doukky, MD, MSc, FASNC, chair of the ASNC Registry Oversight Committee, offers a glimpse at ImageGuide's next leap forward: "The next frontier," he says, "is creating a Tc-99m PYP imaging registry for patients with suspected cardiac amyloidosis.”
