Abstract: PURPOSE: To evaluate the use of color Doppler sonography and free hand sonoelastography in the assessment of breast fibroadenomas according to their size and shape. MATERIALS AND METHODS: From December 2012 to March 2013 women with 16 solid breast masses, classified as BI-RADS category 3 or 4 were examined with B-mode ultrasound, sonoelastography and color Doppler sonography. Lesions were subdivided according to their shape in round, ovoid or macrolobulated and according to their size (<2.0 cm or ≥2.0 cm). Two readers assessed sonoelastographic findings at 12.5 MHz using the tsukuba elasticity score and results of Doppler sonography using a score of 0, 1 or 2, depending on the degree of perfusion. RESULTS: Among the 16 examined lesions 3 showed a round shape, 9 were ovoid and in 4 cases a macrolobulated appearance could be seen. No significant differences concerning Tsukuba-score depending on various shapes of fibroadenomas in B-mode sonography could be shown (p = 0.91) and also comparison of Tsukuba-scores and size of masses revealed no significant differences (p = 1.0). Sizes of fibroadenomas ≥2 cm were significantly associated with an increased vascularization of the lesions (p = 0.04) and a macrolobulated appearance in B-mode sonography (p = 0.04). CONCLUSION: The combination of color Doppler sonography and sonoelastography in addition to B-mode sonography leads to an increased accuracy in distinguishing benign from malignant breast masses and to an improvement in characterization of fibroadenomas independent of their shape or size.
