The cost of a single examination of the Yin ultrasound is around$100. Among medical ultrasound instruments, the higher the frequency of the probe equipped, the more expensive the price point. The frequency of the Yin ultrasound probe is higher than the frequency of the transabdominal probe, so the price of the probe is higher and the cost of one examination is higher than that of transabdominal ultrasound. The higher the frequency of the probe, the clearer the image is, but it needs to be closer to the organ tissue, so the ultrasound is performed by inserting the probe into the vagina, which is also called intracavitary ultrasound. Because it is closer to the uterus, the image quality is better than transabdominal ultrasound, and it is good at observing lesions that are easily missed or misdiagnosed in the uterus and adnexa. The ultrasound probe is long and thin, cylindrical, with a diameter of about 2 cm and a smooth appearance. When the condom is put on, it can enter the vagina smoothly without discomfort because there is a lubricant on the outside of the condom. Since you don’t have to hold urine when doing the ultrasound, you can save time and there is no pain. Although the price is higher than the ordinary ultrasound, its diagnosis rate of gynecological diseases is very high, so it is recommended that married women should prefer the ultrasound for gynecological examination.
