Again, under the second modality, the absence or presence of suspected endometrial lesions will be noted. If suspected lesions are seen, the number of lesions, the extent of the lesions, the lesion color and the surgeon's confidence in the lesion being endometriosis will be recorded. A photograph will be taken, labeled and all lesions will be circled and numbered. Clinicians will record their degree of confidence on a 5 point likert scale that the lesion to be excised is a lesion of endometriosis. The surgeon will record if the lesion was also visualized under the 1st imaging modality or under only one of the modalities.
