| 目的 探讨超声萤火虫技术在检测乳腺肿物微小钙化中的临床应用价值。方法 收集已接受手术或穿刺活检的乳腺肿物患者46例，常规超声共发现69个肿物，选取经X线钼靶摄影和病理结果均证实存在微小钙化的56个肿物作为研究对象，分析56个肿物经常规超声及萤火虫成像技术检测到肿物内微小钙化情况，包括两种技术发现微小钙化的病灶例数，微小钙化的形态及排列特征，比较常规超声与萤火虫技术显示微小钙化的差异。结果 56个肿物中，病理证实恶性肿物42个，良性肿物14个，萤火虫技术检测到微小钙化肿物48个，常规超声检测到微小钙化肿物33个，二者差异有统计学意义（χ2=11.84，P<0.01），42个恶性肿物中，萤火虫技术检测到微小钙化肿物39个，高于常规超声的28个，差异有统计学意义（χ2=8.07，P<0.01）。萤火虫技术检测到良性肿物内微小钙化9个，常规超声检出5个，差异无统计学意义（P>0.05）。常规超声检出的钙化灶大小形态不一，呈点状（n=12）、短棒状（n=6）及多种形态组合型钙化（n=15），而萤火虫技术显示微小钙化均呈现颗粒状或细小的针尖样强光点。常规超声显示的微小钙化的分布特征为局域性（5例，其中恶性3例）、弥漫性散在分布（3例，其中恶性2例）、节段性（6例，其中恶性5例）及簇状分布（19例，其中恶性18例）。萤火虫技术显示的微小钙化分布则为局域性、弥漫性散在分布及簇状分布。萤火虫技术显示的良、恶性乳腺肿物内微小钙化的分布特征差异有统计学意义（χ2=17.11，P<0.01）。结论 超声萤火虫技术可用于检出乳腺肿物微小钙化，在乳腺良恶性肿物鉴别、乳腺癌早期诊断及超声引导下乳腺穿刺活检方面具有重要的价值。 |

| Objective To investigate the clinical application value of MicroPure ultrasonography in detection of microcalcifications of breast masses. Methods Totally 46 patients underwent surgery or puncture biopsy were enrolled in this study. A total of 69 masses were found by ultrasonography and 56 masses confirmed the presence of microcalcifications by X-ray mammography and pathology were selected as the research subjects. The microcalcifications characteristics including the number of cases, the shape and arrangement characteristics detected by ultrasonography and MicroPure ultrasonography technique were analyzed, and the differences were compared. Results In the 56 masses, there were 42 malignant masses and 14 benign masses which were confirmed by pathological diagnosis. Microcalcifications were detected in 48 masses by MicroPure ultrasonography technology, and in 33 massed by ultrasonography, the difference was statistically significant (χ2=11.84, P<0.01). Among the 42 malignant masses, microcalcifications were found in 39 masses by MicroPure ultrasonography technology, higher than that of 28 massed by ultrasonography, the difference was statistically significant (χ2=8.07, P<0.01). In benign masses, microcalcifications were detected in 9 masses by MicroPure ultrasonography, and were 5 massed by ultrasonography, but there was no significant difference between them (P>0.05). The size and shape of ultrasonography in the detection of calcifications were different, including point (n=12), short rod (n=6) and various combination type of calcification (n=15), and the MicroPure ultrasonography technique showed granular or small needle tip like strong point. The distribution characteristics of microcalcification in ultrasonography displayed as localized (5 cases, including 3 malignant cases), diffuse scattered (3 cases, including 2 malignant cases) and segmental (6 cases, including 5 malignant cases) and cluster distribution (19 cases, including 18 malignant cases). The MicroPure ultrasonography technique showed the distribution of microcalcification localized and diffuse. The distribution of microcalcification between benign and malignant breast tumors by the MicroPure ultrasonography technique showed statistical significance (χ2=17.11, P<0.01). Conclusion MicroPure ultrasonography technology can be used to detect microcalcifications of breast masses, and it has important value in differentiation of breast benign and malignant masses, early staging of breast cancer diagnosis and ultrasound guided puncture biopsy of the breast. |
