The application value of low dose scanning technology of multi-slice spiral CT for pulmonary diseases / 中国医学装备

ABSTRACT

Objective:To discuss the value of low dose scanning technique of 16-slice spiral CT for the diagnosis of pulmonary diseases.Methods: A retrospective analysis was adopted to analyze 43 image documents were scanned by 16-slice spiral CT and to evaluate their qualities.Results:All of patients were examined in accordance with the requirements and all of image qualities were more than good. Although their background noise were increased, the image quality did not affect the display of anatomical structure. Therefore, it can satisfy the requirements for the diagnosis of pulmonary diseases.Conclusion:The pulmonary multi-slice spiral CT based on low-dose scanning technology can improve the detection rate of lesions, reduce radiation dose for patients, prolong the service life of the tube and reduce the maintenance cost, therefore it is worthy for further promotion.
