目的 :提高对乳腺疾病的钼靶X线征象认识。材料和方法 :良性病变 6 0例 (6 9个病灶 ) ,恶性病变 5 1例 (5 5个病灶 ) ,年龄 13～ 72岁。患者均行乳腺钼靶X线摄影并经手术病理证实。结果 :良性病灶多为圆形、卵圆形 ,边缘规则 ,等密度、低密度或混合密度 ,80 %的病灶可见完全或不完全的晕环。恶性病灶多为分叶形或不规则形 ,80 %为高密度 ,2 0 %为等密度 ,没有低密度和混合密度病灶。病灶边缘模糊 ,6 1%伴有钙化 ,39%患侧血管增粗扭曲紊乱。结论 :钼靶乳腺摄影是乳腺影象学检查的首选方法 ,95 %以上的病变可望术前作出正确诊断。 Objective :To improve the understanding of mammographic mammographic signs. Materials and methods: 60 cases of benign lesions (6 9 lesions), 51 cases of malignant lesions (5 5 lesions), aged 13 to 72 years old. All patients underwent mammographic mammography and confirmed by pathology. RESULTS: Benign lesions were mostly round, oval, marginal, isodensity, low density, or mixed density, and 80% of lesions showed complete or incomplete halo. Malignant lesions are mostly lobulated or irregular, 80% are high density, 20% are isodensity, and there are no low-density and mixed-density lesions. The edges of the lesions were ambiguous, 6 1% were associated with calcification, and 39% of the affected vessels were thick and distorted. Conclusion : Molybdenum target mammography is the preferred method for breast imaging examination. More than 95% of lesions can be diagnosed correctly before surgery.
