Philips AAA Model improves the patient experience by eliminating exposure to high levels of radiation and nephrotoxic contrast agents, while still providing clinicians with the necessary diagnostic information.
It has been shown that 3D ultrasound can be used to estimate the diameter and volume of an AAA with acceptable reproducibility and an improved agreement with CT2.
3D ultrasound also correlates significantly better to 3D CT than the currently used method of 2D ultrasound when assessing maximum diameter of the residual sac after EVAR, with clinically acceptable reproducibility3.
Procedure | Approximate effective radiation dose | Comparable time period of natural background radiation |
Ultrasound | 0 mSv | 0 years |
Computed tomography (CT): abdomen and pelvis | 10 mSv | 3 years |
X-ray: chest | 0.1 mSv | 10 days |
X-ray: dental | 0.005 mSv | 1 day |
Mammography | 0.4 mSv | 7 weeks |
