MRI Deemed Accurate for Diagnosing Endometriosis

Study finds MRI to be a noninvasive way to map endometriosis before surgery

MONDAY, Oct. 5 (HealthDay News) -- Pelvic MRI is a highly accurate and noninvasive way to diagnose and map endometriosis preoperatively in women suspected of having the condition, according to a study in the October issue of Radiology.

Nathalie Hottat, M.D., and colleagues from the Universite Libre de Bruxelles in Brussels, Belgium, performed 3.0 T pelvic MRI to diagnose and perform deep mapping of endometriosis before surgery in 41 women suspected of having endometriosis.

The researchers found that 66 percent of patients had endometriosis based on surgical and pathologic findings. MRI had a sensitivity of 96.3 percent, a specificity of 100 percent, and an accuracy of 97.6 percent in diagnosing deep endometriosis. Imaging could accurately depict all locations of deep endometriosis, including uterosacral ligaments and the colon wall. Use of an intrarectal gel as contrast did not improve assessment of colon wall infiltration using high-spatial-resolution T2-weighted imaging.

"MR imaging of the pelvis at 3.0 T is accurate in the diagnosis and staging of deep endometriosis for the preoperative assessment of patients clinically suspected of having endometriosis," Hottat and colleagues conclude.
