The meaning of venous flow spectrum in the adnexal region suggests ovarian, tubal or pelvic veins. Adnexal venous flow spectrum is a descriptive term used in ultrasound imaging and is often clarified by color ultrasound. The color Doppler is localized to the blood flow signals, which gives a clear idea of the direction and speed of the blood flow and whether it is venous or arterial signals. If it is a venous blood flow spectrum, it often suggests that the blood flow signal is venous blood flow from the ovaries or fallopian tubes, in addition to considering that it is due to tortuous dilatation of the pelvic veins. In addition to this, a combination of imaging features as well as pulsed multispectral are needed to make a definitive diagnosis. If there is any abnormality, the patient needs to consult the hospital in time, and actively diagnosis and treatment, so as not to delay the condition.
