【摘要】：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(χ~2=11.84,P0.01),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(χ~2=8.07,P0.01)。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(P0.05)。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(χ~2=17.11,P0.01)。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。
[Abstract]:Objective to evaluate the clinical value of ultrasonic firefly technique in detecting microcalcification of breast masses. Methods A total of 69 breast masses were detected by conventional ultrasound in 46 patients who had undergone surgery or puncture biopsy. Fifty-six masses with minimal calcification were selected as the study objects by mammography and pathology. The microcalcification in 56 masses was detected by conventional ultrasound and firefly imaging, including the number of lesions found by two techniques, the shape and arrangement of microcalcification. To compare the difference between conventional ultrasound and firefly technique in showing microcalcification. Results of the 56 tumors, 42 were malignant, 14 were benign, 48 were small calcified by firefly technique and 33 were detected by conventional ultrasound. The difference was statistically significant (蠂 ~ (2 +) 11.84 (P 0.01), P 0.01 (n = 42). There were 39 small calcified masses detected by firefly technique, which was higher than that of conventional ultrasound (28 cases). The difference was statistically significant (蠂 2 + 8.07%, P 0.01). Nine microcalcifications in benign tumors were detected by firefly technique and 5 by conventional ultrasound. The difference was not statistically significant (P 0.05). The size of calcified foci detected by conventional ultrasound was different in size, such as dotted and rod-shaped calcification (6) and various kinds of combined calcification. Firefly technique showed that tiny calcification showed granular or small pinniform intense light spots. The distribution of microcalcification showed by conventional ultrasound was localized in 5 cases, in which 3 cases were malignant, 3 cases were diffuse scattered, 2 cases were malignant, 6 cases were segmental, 5 cases were malignant) and 19 cases were clustered distribution, of which 18 cases were malignant. The microcalcification distribution showed by firefly technique was local, diffuse and cluster distribution. The distribution of microcalcification in benign and malignant breast masses was significantly different by firefly technique (蠂 ~ 2 ~ 2 ~ (17.11) P ~ (0.01). Conclusion Ultrasonic firefly technique can be used to detect small calcification of breast masses, which has important value in differentiating benign and malignant breast masses, early diagnosis of breast cancer and ultrasound guided breast biopsy.
