The researchers studied 41 women, age 20 - 46, with suspected endometriosis. MRI was performed prior to surgery. MRI accurately diagnosed 26 of 27 cases of deep endometriosis. In addition, MR images accurately depicted specific locations of deep endometrial lesions.
"The 3-T MRI results also demonstrated a high negative predictive value of 93.3 percent," Dr. Hottat said, "meaning that MRI findings accurately ruled out deep endometriosis in patients with superficial endometriosis, allowing the surgeon to perform the less invasive laparoscopic procedure."
Colon wall involvement was present in 32 percent of patients with deep endometriosis. MRI was effective at distinguishing different layers of the affected colon wall and accurately depicted the degree of colon wall invasion.
