Abstract 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(P<0.05). 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(P<0.05). 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.
