Abstract：
:Duplex/color Doppler sonography (US) is the imaging modality of choice for the evaluation of patients with primary amenorrhea. Careful correlation with clinical history, physical examination and laboratory findings significantly narrows the diagnostic possibilities thus allowing for a more precise diagnosis. This article discusses the wide gamut of etiologies of primary amenorrhea, the US appearance of pathologic processes that result in primary amenorrhea, and helps the reader understand when additional higher tech imaging is indicated.
