Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose.
The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assist suspected pulmonary embolism patients.
A significant reduction in the average effective dose (39%) was noticed when using the delayed timing bolus protocol.
Delayed timing bolus protocol has a good impact on radiation dose without affecting the value of the computed tomography angiography study.
计算机断层血管造影在肺栓塞诊断中起主要作用。与之相关的辐射剂量是一个主要问题;因此,优化方案和技术以确保最小辐射剂量很重要。
该研究比较了两种方案,即用于辅助疑似肺栓塞患者的传统团注CT方案和延迟团注方案。
使用延迟团注方案时,平均有效剂量显著降低(39%)。
延迟团注方案对辐射剂量有良好影响,且不影响计算机断层血管造影研究的价值。
