Abstract Objective: To establish and analyze its feasibility of a standardized procedure for 13N-ammonia dynamic myocardial perfusion imaging for PET/CT centers. Methods: 13N-ammonia dynamic myocardial perfusion imaging was performed on 53 patients based on the operational procedure from October 2013 to March 2015. Results: From October 2013 to September 2014, termed as primary stage, 43 samples were collected with their original dosage of(31.20±6.53)mCi and calibrated dosage of (23.37±5.22) mCi. The interval was set (4'05"±1'50") and the initial collecting counts(106) were 45.84±10.77. From October 2014 to March 2015, termed as optimizing stage, 10 samples were collected with their original dosage of (26.68±7.37) mCi and calibrated dosage of (20.39±5.41) mCi. The interval was set (3'47"±0'56") and the initial collection counts(106) were 35.08±11.55. Consequently, the images of the 53 samples were clear, indicating the excellent feasibility of this operational procedure. Conclusions: We build up a standardized procedure for 13N-ammonia dynamic myocardial perfusion imaging for PET/CT centers with good feasibility and repeatability and its promotion is recommended.
