Ultrasound can be helpful in identifying some signs of endometriosis, such as ovarian cysts (endometriomas), but it doesn't always detect smaller lesions or adhesions. While you can't necessarily change the outcome of the scan, there are a few things you can do to make the process go as smoothly as possible. First, follow any instructions your healthcare provider gives you, such as drinking water beforehand to have a full bladder if it's a pelvic ultrasound. A full bladder can help improve the visibility of the pelvic organs during the scan. Wearing comfortable clothing can also make the experience easier. If you're anxious about the scan or experiencing discomfort, talk to your technician or doctor before the procedure so they can help make you more comfortable. It’s also worth noting that, in some cases, more specialized imaging, like an MRI, or a diagnostic laparoscopy, might be needed to detect endometriosis more accurately. While laparoscopy was once considered the gold standard for diagnosing endometriosis, it's now often seen as a more traumatic option and is generally avoided unless absolutely necessary. If you're concerned about the effectiveness of the ultrasound, discussing these options with your healthcare provider could be a good next step.
