Abstract: Objective To compare ultrasound imaging features between triple-negative breast cancers and luminal breast cancers. Methods We analyzed ultrasound imaging features at initial diagnosis of 46 triple-negatibe cases and 260 luminal cases. Results Oval shape ( P= 0.000),circumscribed margin,( P=0.021 ) echo pattern（P=0.000）,posterior features（P=0.01） on sonogram were significantly associated with triple-negative breast .Microcalcifications was not（P=0.241）. Conclusions Triple-negative breast cancers had specific characteristic in sonogram .Sonography proves superior in detecting triple-negative breast cancers.
