ABSTRACT
PURPOSE:
To determine whether the compression technique is a valuable additional method for differentiating between benign and malignant breast masses. MATERIALS ANDMETHODS:
The ultrasonographic findings of 95 benign and 53 malignant masses, all pathologically proven, were prospectively analyzed with regard to five diagnostic criteria shape (regular/irregular), retrotumoral acoustic phenomena (posterior enhancement/posterior attenuation), internal echo pattern (homogeneous/inhomogeneous), compression effect on shape (distortion/no change), and compression effect on internal echo pattern (more homogeneous/no change).RESULTS:
The number of cases of benign and malignant masses, respectively, was as follows regular / irregular shape 84/11, 9/44; posterior acoustic enhancement/posterior attenuation 82/13, 16/37; homogeneous/inhomogeneous internal echo pattern 78/17, 14/39; distortion/no change in shpae 76/19, 5/48; and more homogeneous/ no change in internal echo pattern 71/24, 3/50. For all diagnostic criteria for the differentiation of benign and malignant masses, the differences were statistically significant (p<.05).CONCLUSION:
Ultrasonography is helpful for differentiating between benign and malignant breast masses. The compression technique is a valuable additional diagnostic method.
