Reducing computed tomography radiation dose in diagnosing pulmonary embolism
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. 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.
This study aimed to estimate a baseline for the effective doses received by radiography internship students in Saudi Arabia. A retrospective study was conducted from 2015 to 2018 to discern the…
