摘　　要：目的比较超声"萤火虫"成像与X线钼靶摄影对乳腺病灶微小钙化的检出率。方法经手术病理证实的112例乳腺肿瘤患者接受X线钼靶摄影与超声"萤火虫"成像检查。计数两种方法检出的结节内微钙化及结节外簇状微钙化,并进行统计学分析。结果 112例中,X线钼靶摄影检出钙化61个,良性15个,恶性46个,其中结节外簇状钙化6个(均为恶性);超声"萤火虫"成像检出钙化97个,良性33个,恶性64个,其中结节外簇状钙化2个(均为恶性)。X线钼靶摄影未检出而超声"萤火虫"成像显示的钙化36个,其中良性22个,恶性14个。超声"萤火虫"成像检出微钙化灶及恶性病灶优于X线钼靶摄影(P<0.05)。结论与X线钼靶摄影相比,超声"萤火虫"成像可显著提高乳腺恶性肿瘤及微小钙化灶的检出率,提高超声对乳腺恶性病灶的诊断准确率。Objective To observe the value on demonstrating microcalcification with micro-pure imaging system of ultrasonography and mammography.Methods A total of 112 patients confirmed pathologically underwent micro-pure imaging system of ultrasonography and mammography.The clustered microcalcifications outside the nodules and microcafications inside the nodules were calculated respectively and analyzed statistically.Results In 112 patients,61 microcalcifications were detected with mammography,including 15 benign and 46 malignant.The clustered microcalcifications outside the nodules were found in 6 and all were proved malignant.Ninety-seven microcalcifications inside nodules were detected with micro-pure imaging system,including 33 benign and 64 malignant.The clustered microcalcifications outside the nodules were found in 2,and both were proved malignant.Thirty-six microcalcifications in 22 benign nodules and 14 malignant nodules that were not found with mammography were detected with micro-pure imaging system.The demonstration ratio on microcalcifications of micro-pure imaging system was significantly higher than that of mammography（P〈0.05）.Conclusion Compared with mammography,micro-pure imaging system of ultrasonography improves the demonstration ratio on microcalcification of breast tumor significantly and increases the diagnosis ratio of breast tumor.
