RSNA 2011: Virtual hysterosalpingography with CT scanning emerges as new standard
In assessing abnormalities of the female reproductive tract, computed tomography virtual hysterosalpingography (CT-VHSG) is credited with being highly accurate, very safe, and well accepted by patients. Performed with 64- or 256-row CT after instilling contrast agent through the vagina into the reproductive anatomy, the procedure can be performed in a few seconds with a radiation dose of approximately 0.3 mSv or less. In an overview based on a series of 4500 cases, most of whom had problems with infertility, this procedure was able to provide adequate information to provide a diagnosis of the underlying problem in most cases. A series of technological advances in CT were credited with permitting this approach to provide detailed information on all major anatomical structures in the reproductive tract, but the current technology appears to confer this approach with a level of accuracy that is equal to or superior to alternative but more invasive approaches.
