The Usefulness of Computed Tomographic Colonography for Evaluation of Deep Infiltrating Endometriosis

Abstract

Both CT colonography and MRI are highly sensitive to the detection of rectosigmoid endometriosis, but lack specificity. However, the depiction rate of morphologic change in rectosigmoid colon is greater with CT colonography than that of MRI, in the case of cul-de-sac obliteration. The luminal alteration significantly correlates with morphologic change in rectosigmoid endometriosis.
