[摘要] 目的：探讨相位对比乳腺钼靶成像技术特点及临床应用价值。方法：应用日本REGIUS PureView M型相位对比乳腺成像系统，2010年7~12月共检查患者1 173例，双侧乳腺对比检查，投照体位均包括侧斜位和轴位，采用多中心电离室控制全自动曝光，曝光千伏26~34 kV，毫安秒29~117 mAs。结果：双侧乳腺轴位及侧斜位对称显示，图像质量均符合乳腺摄影质量控制合格标准，乳房皮肤、皮下脂肪、乳腺、胸大肌及腋窝组织等不同组织结构均衡清晰显示，对致密型乳腺内0.1~0.2 mm微小钙化灶显示清晰。X线曝光剂量较低。经手术病理证实恶性肿瘤47例，其中，女46例，年龄24~88岁，平均53.13岁，右侧22例，左侧26例；男性1例，55岁，左侧。良性肿瘤72例，均为女性，年龄19~70岁，平均40.88岁，右侧41例，左侧40例，双侧病灶者9例。结论：相位对比乳腺成像技术影像学特点突出，为乳腺癌诊断和鉴别诊断提供可靠依据。

[Abstract] Objective: To Study the characteristics and clinical application value of phase contrast mammography system (PCM). Methods: 1 173 patients from July to December in 2010 with the PCM of Japanese REJIUS Pureview M type were examined. Double side breast was examined in both MLO and CC comparably of every patient. The exposure be controlled by polycentric ionization chamber with 26-34 kV and 29-117 mAs. Results: The high guality PCM images revealed the breast skin, subcutaneous fat, mammary gland, pectoralis major, armpit organization and some other organization structures clearly. And it also had a clear image on the compact mammary gland′s microcaleifications which were 0.1-0.2 mm. The X-ray exposure dose was low. 47 breast cancer on firmed by the surgical operation pathology. Among them, the female were 46 cases, the age was 24-88 years old, on the average was 53.13 years old, the right side were 22 cases, the left side were 26 cases, only one male was 55 years old, left side; and the benign tumor were 72 cases, all were female, the age was 19-70 years old, on the average was 40.88 years old, the right side were 41 cases, the left side were 40 cases, double side focus were 9 cases ......
