As we know, in X-ray imaging methods such as simple X-ray or CT scan, the body is exposed to a certain amount of ionizing radiation. However, X-ray are not used in ultrasound. The waves used in ultrasound are sonic waves, and they are in fact sound which is not harmful to the body. These waves, which are exactly like sound, but they are not audible by the human ear because of their high frequency. Nevertheless, they have properties of the sound; that is, they are rebounded after hitting obstacles.
Ultrasound imaging is not painful and the patient feels no discomfort during the procedure.
In ultrasound, most soft tissues of the organs can be seen and examined. Thus, ultrasound is not a suitable method for detecting bone problems. However, it can examine the problems in the muscles of ligaments and tendons and many other tissues.
Ultrasound my be two-dimensional or three-dimensional. Meanwhile, the ultrasound images of organs can be seen while in motion and activity.
There is a special type of ultrasound called Doppler ultrasound. This imaging technique works on the basis of the Doppler phenomenon and aims to check the amount and speed of blood flow in the body veins and arteries. This method is more used for assessing the possibility of clots in the deep veins of the leg.
color doppler ultrasonography:
Doppler ultrasound of vessels
Doppler of abdominal organ (Doppler of liver, Doppler of abdomen, Doppler of pelvis, Doppler of kidney) Doppler of the upper limps and lower limbs
Doppler of carotid
Pregnancy Doppler (Doppler of placenta and fetus)
Doppler of testicles
Penile Doppler with injection
Routine ultrasounds (abdomen, pelvis, breast, soft tissue, thyroid, etc)
Ultrasound for determining pregnancy
Vaginal Ultrasound of uterus
Screening of the second phase and anomaly
