Abstract :
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.
