   — John T. Queenan, M.D., in response to a question about the three most significant technological developments in obstetrics and gynecology during the previous 30 years (1950 to 1980)

CT and MRI may attract more attention, but “ultrasound continues to be the workhorse”1 for imaging in gynecology. The reasons are not hard to understand. Ultrasonography is noninvasive and has a perfect safety record. It is portable and relatively easy to use, and it produces images, including moving ones, immediately. And it costs much less than other modalities to obtain and operate.

Ultrasonography is becoming even more popular as new technology expands its capabilities and manufacturers offer packages of features specific for particular specialties, including gynecology and obstetrics. This article takes a look at some applications of ultrasonography in women’s health in 2002.

New Capabilities
Because of the nature of ultrasonography data, three-dimensional rendering came more slowly to this modality, and for some time, 3D images were available only through extensive offline manipulation. Real-time 3D imaging is now available, making it possible even for operators with less experience to depict complex anatomy accurately, both for diagnosis and for discussions with other physicians and with patients. Views not available from 2D scans also become possible, and the accuracy of volume calculations improves dramatically. CPT codes are available for reimbursement for some 3D studies performed to obtain a second opinion.
