Objective: To comprehensively analyze the clinical value of the low-dose and low-concentration application of CT scanning technology in patients with acute pulmonary embolism (APE).Methods: The main subjects of this study were: APE patients (86 cases were selected in March 2021 and ended in March 2022). According to the digital random table method, it was divided into two groups (43 cases in each group), one was control group (applying conventional CT scanning technology) and the other was experimental group (using CT low dose and low concentration scanning technology).Results: Comparing the CT dose index, CT value, noise, image signal-to-noise ratio (SNR), and contrast noise ratio (CNR), the results showed that the experimental group was higher than the control group (P <0.05). Comparing the two groups of image scores, the positive detection rate, the main pulmonary artery, left pulmonary artery, right pulmonary artery, right pulmonary artery, left and right superior pulmonary artery, left and right basal pulmonary artery subsegment, and left and right basal pulmonary artery, the results showed no difference between the two groups (P> 0.05). Comparing the two groups of radiation doses (DLP), the results showed that the experimental group was lower than the control group (P <0.05). Conclusion: The clinical value of applying CT low-dose and low-concentration scanning technology in APE patients is higher than the conventional CT scanning technology, which can significantly reduce DLP, improve SNR, CNR, CT dose index and CT value.
