There are certain differences between ultrasound and B-ultrasound, and the most important issue of the difference is the different positions of the probe placement, and the others are basically roughly the same. In an ordinary ultrasound, the probe is placed on the surface of the organs, such as the liver, gallbladder, pancreas, spleen and kidney, and the ultrasound probe is placed on the chest wall, moving above the position of the liver. The ultrasound probe is placed inside the woman’s vagina, so some women may experience vaginal cramps or other discomforts due to excessive nervousness that cause the ultrasound procedure to be less than smooth. In fact, ultrasound is more convenient and accurate than normal ultrasound for the examination of the uterus and ovaries, and the diagnosis of uterine and ovarian diseases is more clear.
