What is the difference between transvaginal ultrasound and colposcopy?

There are clear differences between transvaginal ultrasound and colposcopy in gynecological examinations. Transvaginal ultrasound, also known as vaginal ultrasound, involves inserting an ultrasound probe into the vagina or rectum to perform ultrasonic diagnosis. It is particularly suitable for observing pelvic organs within the small pelvis, such as the uterus and ovaries. This method provides clear images and accurate results, and does not require a full bladder, making it especially useful for monitoring ovulation and confirming ectopic pregnancies. Colposcopy, also known as vaginal镜 (colposcope), is a common gynecological endoscope that allows doctors to clearly observe tiny lesions on the cervix and within the vagina by magnifying the view many times. It offers high diagnostic accuracy for cervical and vaginal abnormalities and is primarily used for patients with abnormal cervical cytology findings or those suspected of having cervical precancerous lesions.
