AIM: To determine the influence of weight, height, gender, age, heart rate, and blood pressure on count rate in cadmium-zinc-telluride single-photon emission computed tomography (CZT SPECT) gated radionuclide angiography.

METHOD: A total of 1,065 eligible patients referred for routine assessment of left ventricular ejection fraction were registered from August 2015 to November 2016. Data were recorded on heart rate, systolic and diastolic blood pressure, age, gender, height, weight, and count rate. All radionuclide angiographies were performed on a dedicated cardiac CZT SPECT camera, GE Discovery 530c. A dose of 550 MBq 99mTc-labeled human serum albumin was administered intravenously to each patient.

RESULTS: Count rate varied from 1.2 to 8.9 counts per second. All test variables were significantly associated with count rate. From the preliminary analysis, weight appeared as the main contributing factor for explaining the variations in count rate with and R2 of 0.68. A model consisting of weight, height, gender, and age explains 75% of the variance in count rate.

CONCLUSION: Patient height, weight, gender, and age have significant impact on count rate when performing CZT radionuclide angiography and may subsequently be used for individualized planning of tracer dosage.
