乳腺癌的X线征象分析

目的进一步提高乳腺癌的X线诊断水平。方法回顾性分析经手术病理证实的158例乳腺癌的X线表现。结果年龄40-59岁为乳腺癌高发年龄组121例(76.58%)。发病部位以外上象限为多见(63.92%)。乳腺癌的X线直接征象:肿块135例(85.43%),多形不规则密集钙化70例(44.30%)。间接征象:乳腺结构紊乱20例,不规则致密区或斑片状致密影8例,邻近血管增粗6例。结论乳腺钼靶摄影是诊断乳腺癌最主要的方法之一,主要表现为局部密度增高可有块影,多形不规则密集钙化,乳腺结构紊乱。

Analysis of radiologic signs in breast cancer

Objective To furthermore raise the roentgenologic diagnostic level of breast cancer. Methods The roentgen logic features of 158 cases of breast cancer confirmed by surgicopathology were analyzed retrospectively. Results Among 158 case, 121 cases (76.58%) were proved in breast cancer of high-risk ages (40-59y). The predilection sites were located in the lateral upper quadrant (63.92%). The direct signs of breast cancer by mammography: mass formation (85.43%); multimorphologic irregular clustering of calcification, (44.30%). The indirect signs included: structural distortion of breast tissue in 20 cases; irregular hyperdense area as patchy hyperdense in shadow, 8 cases; increase calibers of nearby vessels in 6 cases. Conclusion Mammography is one of the major modalities for diagnosing breast cancer, the local hyperdense area associated with mass formation, multimorphologic irregular clustering calcifications and tissue structural distortion are the criteria for roentgenologic diagnosis.
