New ASNC-led guideline details how to use CT in hybrid nuclear-CT cardiac imaging

The American Society of Nuclear Cardiology (ASNC) and three partner societies have come together to answer cardiac imagers’ questions about SPECT/CT and PET/CT imaging with attenuation correction, localization of radiotracer uptake and coronary artery calcium scoring (CACS). In a new multisociety guideline published today in the Journal of Nuclear Cardiology, the organizations recommend training and competency requirements for imaging physicians and technologists; describe models for collaborative, cross-specialty study interpretation and reporting; and suggest solutions for the preauthorization and reimbursement challenges that some labs have faced with hybrid imaging in nuclear cardiology.

Authored and endorsed by ASNC and the American Association of Physicists in Medicine (AAPM), Society of Cardiovascular Computed Tomography (SCCT) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI), the new guideline highlights how SPECT/CT and PET/CT testing improve diagnostic accuracy and risk-stratification in patients with known or suspected coronary artery disease as well as the clinical value of hybrid nuclear-CT imaging in assessing infection, inflammation, viability and hibernation in cardiac patients.

“Hybrid imaging is helping cardiology teams enhance image quality and obtain new information that impact treatment decisions and our patients’ long-term outcomes,” says ASNC President-elect Mouaz H. Al-Mallah, MD, MSc, FASNC, cardiac PET chair at Houston Methodist DeBakey Heart and Vascular Center and the new guideline’s lead author. “Assessing atherosclerosis burden in hybrid imaging improves the diagnostic accuracy of MPI studies and help clinicians identify high-risk patients and treat them accordingly. The question is not whether today’s cardiac imaging labs should adopt hybrid imaging but rather how to adapt their labs for the routine use of SPECT/CT and PET/CT. There are practical day-to-day issues that can become obstacles for labs. We developed this guideline to show the options available for managing the practical issues, thus making hybrid nuclear-CT imaging more accessible for patients who will benefit from it.”
