摘要
目的:评价超声"萤火虫"成像技术对乳腺微小钙化灶的检测能力。材料与方法:对43例经钼靶X线片证实存在96个乳腺微小钙化灶、拟行活检的患者分别行超声"萤火虫"成像与常规超声检查,评价超声"萤火虫"成像技术显示乳腺微小钙化灶的能力。结果:超声"萤火虫"成像共在43例患者中显示出94个微小钙化灶,明显高于常规超声的发现能力(66个);二者比较,差异有显著性(P<0.05)。超声"萤火虫"成像共在31例恶性患者中的30例中发现存在微小钙化灶,明显高于常规超声的检测结果(18例,P<0.05);在声像图低回声背景内,超声"萤火虫"成像检出其中64个微小钙化灶中的62个,亦明显高于常规超声的检出结果(40个,P<0.05);同时,超声"萤火虫"成像对良恶性乳腺组织内的钙化灶均有较强发现能力。结论:超声"萤火虫"成像技术比常规超声显示乳腺微小钙化灶的能力更强,尤其是对声像图低回声背景内的微小钙化灶显示较好;提示"萤火虫"成像技术有助于提高超声对早期乳腺癌的发现能力。
Objective： To research the detectability of MicroPure system on breast micro-calcifications.Materials and Methods： Forty-three patients with 96 separate micro-calcifications in breast confirmed by the molybdenum target X-ray system were given MicroPure system detection and conventional ultrasound imaging technology respectively.Results： Ninety-four micro-calcifications were detected by MicroPure system,however,there were only 66 micro-calcifications found by conventional imaging technology.There was significant difference between them（P0.05）.Micro-calcifications were found in 30 patients with breast cancer of all the 31 patients with breast cancer by MicroPure system.When compared with conventional ultrasound imaging technology（18 patients）,there was significant difference between them（P0.05）.In addition,the results also showed that MicroPure system detected more micro-calcifications（62 lesions） within hypoechoic lesions（64 lesions） than conventional ultrasound imaging technology（40 lesions） in patients with breast cancer.At the same time,the detectability of MicroPure system for micro-calcification in benign and malignant breast tissue was very high.Conclusion： MicroPure system can detect micro-calcifications and has a better visibility for micro-calcifications within hypoechoic lesions,which suggests that the MicroPure system has the ability to discover early breast cancer.
