Diagnostic accuracy of hysteroscopy, ultrasound and magnetic resonance imaging in detecting congenital uterine anomalies.

Congenital uterine malformations occur as a result of a defective uterine development. The formation of the uterus is a dynamic process that culminates after completing four phases (differentiation, fusion, migration and canalization). Because is an evolutionary process, the resulting uterine malformation is different depending on the uterine formation phase in which the failure occurs. To establish a correct diagnosis of uterine malformations, it is necessary to evaluate both the shape of the uterine cavity and the external contour of the uterus. In this review we will describe the imaging modalities used in current clinical practice for the evaluation of the patient with suspected congenital uterine anomalies. The current role of each modality is described.
