"双低"技术结合迭代重建技术在64排螺旋CT肺动脉造影中的综合应用
Application of double-low technique and iterative reconstruction in 64-slice MSCT pulmonary angiography
摘要
Abstract
The development of CT and the clinical application of CT pulmonary angiography (CTPA) in diagnosing pulmonary embolism were introduced,and the methods for decreasing CTPA radiation dose and the importance of iterative reconstruction for low-dose scanning were analyzed.The development and application of contrast agent were described,and the ways to reduce contrast agent dose was expounded.Double-low CTPA combined with iterative reconstruction was pointed out to decrease greatly the radiation dose and contrast agent iodine dose while ensured image quality,and thus the damages to the patient by radiation and contrast agent could be lowered at the most.关键词
