Is abdominal ultrasound accurate during menstruation

Abdominal ultrasound during menstruation is usually accurate, but image clarity may be affected by factors such as endometrial thickening. The results of abdominal ultrasound examination are mainly influenced by factors such as bladder filling and surgical techniques, and menstruation is not an absolute contraindication. During menstruation, when performing abdominal ultrasound examination, the uterus is in a congested state, and thickening of the endometrium may affect the diagnosis of intrauterine lesions. However, morphological examination of pelvic organs such as ovaries and fallopian tubes can still provide effective information. The diagnostic accuracy of space occupying lesions such as cysts and fibroids is relatively small. Before the examination, it is necessary to keep the bladder moderately full, which can help improve the image quality. If it is necessary to evaluate endometrial lesions or perform fine examinations such as follicle monitoring, endometrial shedding during menstruation may interfere with the interpretation of results. At this time, it is recommended to have a follow-up examination 3-7 days after the menstrual cycle is clean. However, for emergency situations such as ectopic pregnancy rupture, corpus luteum rupture, and other acute abdominal conditions, immediate ultrasound examination is still necessary during menstruation to confirm the diagnosis. After the SEP examination, apply appropriate hot compress to the lower abdomen to relieve discomfort and avoid vigorous exercise. It is recommended to wear loose clothing for easy inspection, and drink 500-800 milliliters of water one hour before the inspection to keep the bladder full. Those with severe dysmenorrhea or excessive menstrual flow can inform the doctor in advance and adjust the examination time if necessary. The examination results should be comprehensively judged based on clinical symptoms and other examinations, and if necessary, follow medical advice for re examination.
