New 2018 guidelines for myocardial perfusion imaging (MPI) protocols on conventional and novel single photon emission computed tomography (SPECT) for nuclear cardiology practitioners has received praise from the Society for Nuclear Medicine and Molecular Imaging (SNMMI).

Physicians in fields like cardiology have traditionally looked to clinical practice guidelines to help articulate the best evidence-based care for patients. The rapidly growing movement to value-based care is prompting clinicians—including echocardiographers—to carefully weigh a more focused and integrative approach to delivering consistent, quality medicine: care pathways.

Organizations are working in sync to put a focus on mandating optimized radiation doses in nuclear cardiology studies performed across the nation and beyond. 

After reviewing the available literature, the societies said that rest-stress myocardial perfusion PET was a first-line preferred test for patients with known or suspected coronary artery disease who meet the criteria for stress imaging and are unable to complete the diagnostic level exercise stress imaging study.

While amyloid imaging is typically discussed with regard to diagnosing Alzheimer’s disease, a team of French researchers, presenting at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 annual meeting, have found that amyloid scans of the heart can predict major cardiac events.

PET with 11C-PIB provides a noninvasive method for visualizing amyloid deposits in the heart, according to a study published in the February issue of the Journal of Nuclear Medicine. The researchers suggest that 11C-PIB eventually may be used in the clinical setting as both a diagnostic tool and a treatment follow-up method.
