Reducing computed tomography radiation dose in diagnosing pulmonary embolism

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.
