Ovarian Torsion and Its Mimics

Color flow Doppler (CFD) imaging provides valuable information about the vascularity of tissue, organs, or systems. CFD imaging is commonly used during the evaluation of uterus and ovaries in addition to gray-scale imaging and is a helpful imaging modality in the diagnosis of various pathologic conditions in gynecology and obstetrics. The main limitation of CFD imaging is its user dependency that may lead to misdiagnosis owing to the artifacts or pitfalls derived from improper technique, incorrect use of imaging parameters, and unawareness of physical properties of the modality by the user. This article summarizes the CFD imaging technique, the optimization of imaging parameters, and the useful findings in the evaluation of uterus and ovaries.
