Will gynecological ultrasound during menstruation affect the results

gynecological ultrasound during menstruation generally does not affect the examination results, but it may affect the observation effect of some items due to menstrual blood interference. Gynecological ultrasound examination mainly includes two methods: transabdominal and transvaginal. Endometrial shedding during menstruation may have a slight impact on the image clarity of transvaginal ultrasound, while the impact on transabdominal ultrasound is relatively small.

During menstruation, gynecological ultrasound examination is usually not significantly disturbed by abdominal ultrasound, which is suitable for observing larger lesions such as uterine fibroids and ovarian cysts. Before the examination, hold your urine to fill the bladder for ultrasound penetration. Menstrual bleeding does not affect the overall evaluation of pelvic organs by ultrasound, but may reduce the accuracy of determining subtle structures such as endometrial thickness. Transvaginal ultrasound may come into contact with blood during menstruation, affecting image quality, but it still has value in observing deep tissues such as ovaries and fallopian tubes. In rare cases, excessive bleeding during menstruation may cause blurred vision on transvaginal ultrasound, and doctors may recommend switching to abdominal ultrasound or delaying the examination. If it is necessary to evaluate endometrial lesions or monitor follicular development, it is more appropriate to check 3-7 days after the end of menstruation. Menstrual ultrasound is still a necessary diagnostic tool in emergency situations such as acute lower abdominal pain or abnormal bleeding.

Before the examination, the doctor should be informed of the menstrual cycle situation, and the doctor will choose the appropriate method based on the specific examination purpose. Re examination after menstruation can improve the accuracy of certain items, but routine screening or emergency evaluation is not absolutely limited. After the examination, keep the perineum clean and avoid vigorous exercise. If there is any discomfort, seek medical attention promptly.
