| 目的 评价超声微钙化点增强成像技术显示乳腺肿瘤内微钙化的能力。方法 分别应用高频超声及微钙化点增强技术检查57个乳腺肿瘤内微钙化灶,评价两种技术显示乳腺肿瘤内微钙化的能力。结果 微钙化点增强技术对57个乳腺肿瘤内微钙化的检出率(47/57,82.45%)明显高于高频超声(35/57,61.40%),差异有统计学意义(P<0.01)。微钙化点增强技术对乳腺良性、恶性肿瘤内微钙化灶的检出率分别为85.71%(18/21)、80.56%(29/36),均高于高频超声(12/21,57.14%;23/36,63.89%),差异均有统计学意义(P均<0.05)。微钙化点增强技术对低回声肿瘤内微钙化灶的检出率(26/33,78.78%)高于高频超声(21/33,63.63%),但差异无统计学意义(P>0.05);对非低回声肿瘤内微钙化的检出率(21/24,87.50%)高于高频超声(14/24,58.33%),差异有统计学意义(P<0.05)。结论 微钙化点增强技术较高频超声能够更好地显示乳腺肿瘤内的微钙化。 |

| Objective To assess the value of MicroPure imaging in detecting microcalcifications in breast neoplasms. Methods Microcalcifications of 57 breast neoplasms were detected with MicroPure imaging and high-frequency ultrasonography respectively, and the abilities to detect microcalcifications in breast neoplasms of these two methods were analyzed statistically. Results The detection rate of MicroPure imaging of breast microcalcification was 82.45% (47/57), significantly higher than that of high-frequency ultrasonography (35/57, 61.40%). There was significant difference between the two methods (P<0.01). The detection rate of MicroPure imaging for benign and malignant breast microcalcifications was 85.71% (18/21) and 80.56% (29/36), respectively, obviously higher than those of high-frequency ultrasonography (12/21, 57.14%; 23/36, 63.89%), and the differences were statistically significant (all P<0.05). The detection rate of MicroPure imaging for breast microcalcification (26/33, 78.78%) was higher than that of high-frequency ultrasonography (21/33, 63.63%) in hypoechoic tumors, but no significant difference was found (P>0.05). Difference of the detection rate for non-hypoechoic breast microcalcificationions was found between MicroPure imaging (21/24, 87.50%) and high-frequency ultrasonography (14/24, 58.33%, P<0.05). Conclusion Compared with high-frequency ultrasonography, MicroPure imaging can better show microcalcifications within breast neoplasms. |
