The Diagnostic Accuracy of Ultrasound in Assessment of Myometrial Invasion in Endometrial Cancer: Subjective Assessment versus Objective Techniques

Figure 1

Ultrasound images and schematic diagrams showing deepest invasion, the largest distance in any plane between endometrium-myometrium junction and maximum tumor depth, and corresponding normal myometrium assessed as the myometrial width aside of the deepest tumor invasion without fibroids; (a-b) deepest invasion/normal myometrium ratio ≥ 0.5 reflecting the deep invasion, histologically proven FIGO stage IB; (c-d) deepest invasion/normal myometrium ratio < 0.5 indicating superficial invasion, histologically proven FIGO IA.
