A common diagnostic method for endometriosis is:

The most common diagnostic method for endometriosis is laparoscopy. This minimally invasive surgical procedure allows direct visualization of the pelvic organs, enabling the clinician to identify and biopsy endometrial lesions. During laparoscopy, the abdomen is inflated with gas to provide a better view, and specialized instruments can be used to assess the extent of the disease.

While imaging techniques like ultrasound, MRI, and CT scans can provide valuable information and support the diagnosis of endometriosis, they are generally considered less definitive than laparoscopy. Ultrasound can help identify cysts associated with endometriosis, such as endometriomas, but it may not detect small lesions. MRI can offer detailed images of the pelvic anatomy and may assist in evaluating larger or deep infiltrating endometriosis, but it does not provide direct confirmation. CT scans are not typically used for diagnosing endometriosis as they do not offer the same level of detail as MRI or laparoscopy. Therefore, laparoscopy remains the gold standard for confirming the diagnosis and assessing the extent of the disease.
