Value of direct and indirect uitrasonographic signs in diagnosis of small breast cancer / 中华超声影像学杂志

ABSTRACT

Objective To explore the value of direct and indirect ultrasonographic signs in diagnosis of small breast cancer. Methods The sonographic features of 103 small breast lesions (47 malignant, 56 benign) were retrospectively analyzed and divided into direct and indirect signs according to the pathology.The results of ultrasonography were compared with pathology. Agreement was measured with K statistics between ultrasonographie signs and pathology. Results Compared with the malignant and benign small breast noplasms, there was statistical significance of the direact signs of micro calcifications, grade Ⅱ- Ⅲ flow,resistance index (RI)≥0.7 and the indireact signs of changes of superficial fascia (P<0.01).Agreement was moderate for micro calcifications, grade Ⅱ-Ⅲ flow, RI≥0.7, changes of superficial fascia (0.7> K≥0.4) ,and substantial for the combination of direct and indirect signs(K=0.726). Conclusions Combination of direct and indirect ultrasonographie signs was significant in diagnosis of small breast cancer.
