Results of a new study show that breast sonography is more accurate than mammography in symptomatic women 45 years old or younger, and may be an appropriate initial imaging test in investigating these women, says Nehmat Houssami, MD, PhD, and lead author of the study. The study, published in the April 2003 issue of the American Journal of Roentgenology, “is the first published study to examine the comparative sensitivity and specificity of mammography and sonography in relation to age in young women with breast symptoms, where the two tests were interpreted independently of each other and where almost all subjects had undergone both tests,” says Dr. Houssami.
