چکیده
|
Background and objective: 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. methods: the study compares two protocols i.e. conventional timing bolus ct protocol and delayed timing bolus protocol used to assist suspected pulmonary embolism patients. results: a significant reduction in the average effective dose (39%) was noticed when using the delayed timing bolus protocol. conclusion: delayed timing bolus protocol has a good impact on radiation dose without affecting the value of the computed tomography angiography study. © 2016,professional medical publications. all rights reserved.
