Abstract：Objective:To explore the effect of different fasting regimens on patients' comfort,physiological indexes and examination results of positron emission computed tomography (PET/CT) multimodal imaging.Methods:A total of 150 cases of patients with PET/CT multimodal imaging were divided into group A,group B and group C by random number table method.The patients in three groups received fasting at 4 h,6 h and 8 h before examination after oral light liquid diet,respectively.The comfort,physiological parameters and examination results were compared in patients with different fasting regimens.Results:The systolic blood pressure,diastolic blood pressure and blood glucose in group A were significantly higher than those in the other two groups (P<0.01),and systolic blood pressure and blood glucose decreased significantly with the extension of fasting time (P<0.05 or P<0.01) The levels of starvation,thirst,tired,fatigue and weakness were significantly lower than those in the other two groups (P<0.01),among which starvation,weakness,tired and fatigue were significantly increased with the extension of fasting time.The degree of cooperation was better and examination time was shorter than those in the other two groups (P<0.01).Conclusions:Shortening the fasting time to more than 4 h could help to improve the patient's comfort before PET/CT multimodal imaging,maintain stable physiological indexes and improve the efficiency of the examination.
