Color Doppler Ultrasound in Uterine Arterial Embolization
1Ultrasonography Department of Linyi People's Hospital, Shandong Province, Linyi, 276003, China.
Objective:
To observe and analyze the effect of color doppler ultrasonography (CDU) in uterine arterial embolization (UAE).
Methods:
160 cases of patients with uterine fibroid were selected in this study. CDU were performed on all patients before UAE as well as 5-9 days and 3-6 months after UAE, so as to observe the shape, size and ultrasonogram of the uterus and uterine fibroid, and the blood flow changes of the uterine fibroid. In addition, analysis was carried out on the improvement of the clinical symptoms 3 months to 6 months after UAE.
Results:
5-9 days and 3-6 months after UAE, the blood flow of uterine fibroid was significantly reduced or even disappeared, with P <0.05; according to the observation carried out 3-6 months after UAE, irregular menstruation and uterine fibroid compression were significantly relieved; the uterine size and the uterine fibroid volume were significantly decreased;high-level echo was generated inside of the uterine fibroid, which was then gradually reduced into slightly higher echo, equal echo and low echo. High-level echo was found around the uterine fibroid.
Conclusion:
It is safe and reliable for the patients with symptomatic uterine fibroid to take UAE. The application of CDU can also provide a good basis and has great significance.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
