Patient-centered imaging B Background: b Recently, professional societies have recognized the need to develop imaging protocols that are adaptable to a patient's specific need.[76],[77] Specifically, protocols should be adaptable to increase the administered radionuclide dosage when patients have a higher body mass index (BMI) and reduce that dose for lower BMI patients. B Definition of measure: b I Use of patient-centered SPECT MPI protocols. i Confirm the site has written protocols for modifying the imaging protocol for specific populations: Using different patient doses or variable acquisition times for low and high BMI patients. Literature demonstrates that attenuation mitigation strategies improve the normalcy rate of stress-first imaging.[88]-[90] B Definition of measure: b I Percentage of Tc-99m stress SPECT MPI studies performed with stress-only imaging. i B Rationale for inclusion: b Stress-only imaging, when possible, substantially reduces radiation dosage and improves patient convenience and experience compared to stress-rest or rest-stress protocols. It is rarely appropriate to repeat imaging if < 2 years after PCI.[8] Imaging post revascularization is a common indication for SPECT MPI, and nuclear labs should encourage high-value imaging guided by a change in clinical status that is concerning for ischemia, assessment of ischemia in the setting of incomplete revascularization or progression of disease.
